Authorized Service Centers  
The unit is a precision instrument. Although it has been designed for optimum  
durability and trouble free operation, it must be handled with care.  
Most probes have handle temperature limits. Be sure that the probe handle tem-  
perature limit is not exceeded in the air above the instrument.  
The instrument and any thermometer probes used with it are sensitive instru-  
ments that can be easily damaged. Always handle these devices with care. Do  
not allow them to be dropped, struck, stressed, or overheated.  
When calibrating PRTs always follow correct calibration procedure and cali-  
brate from high temperatures to low temperatures with the appropriate triple  
point of water checks. Never immerse a wet or cold PRT into a bath filled with  
hot medium. Severe damage to the PRT may result as well as personal injury to  
the calibration technician.  
This furnace is not designed to be portable. Therefore, moving the furnace once  
it has been installed should be kept to a minimum. To safely move the furnace,  
two people are required. One person should lift the furnace at each end of the  
furnace, place their hand under the control drawer, and lift simultaneously be-  
ing careful not to tip. Ensure that the furnace is de-energized and cooled to less  
then 100°C. Remove the equilibration block prior to moving. The equilibration  
block can damage the fused silica tube that is extremely fragile.  
The control probe must be inserted properly in the instrument and plugged into  
the socket at the back of the furnace. DO NOT operate the furnace without the  
control probe properly inserted and attached. The furnace will not operate cor-  
rectly without the control probe. Injury to operating personnel and permanent  
damage to the furnace could occur.  
Components and heater lifetimes can be shortened by continuous high tempera-  
ture operation.  
If a mains supply power fluctuation occurs, immediately turn off the furnace.  
Power bumps from brown-outs and black-outs can damage the instrument. Wait  
until the power has stabilized before re-energizing the furnace.  
The probe and the block may expand at different rates. Allow for probe expan-  
sion inside the well as the block heats. Otherwise, the probe may become stuck  
in the well.  
Be aware that the equilibration block expands as the furnace heats. It will ex-  
tend beyond the front of the furnace at high temperatures anywhere from ¼ to  
approximately ½ inch. This is normal and is due to thermal expansion.  
Take care that all sensors used as references or being calibrated in the furnace  
are capable of withstanding the desired temperature range to be used.

Introduction  
The 9112A Calibration Furnace was designed specifically for calibrating PRTs,  
fiber optic sensors and thermocouples at higher temperature ranges up to  
1100°C. The furnace utilizes an equilibration block capable of making compar-  
ison measurements on multiple probes. The standard equilibration block is  
sized for ¼ inch probes, however, custom options are possible. Temperature  
stability is better than 0.1°C throughout the range and the gradient between  
wells at full insertion is less than 0.5°C ( 0.25°C).  
The temperature control system utilizes a digital controller with a Type K ther-  
mocouple control sensor and RS-232 interface. The controller displays the set  
temperature and the actual temperature simultaneously. The display shows tem-  
perature to the nearest degree in °C or °F (shipped in °C). The temperature is  
set with convenient up and down buttons on the front panel.  
Sensors being calibrated as well as the furnace itself are protected from exces-  
sive temperature with an over-temperature cutout. The cutout is easily adjusted  
from the front panel. This device is relay operated and protects against the pos-  
sibility of thermal runaway due to a shorted solid-state relay which controls the  
heaters.

Location  
The furnace is intended to be installed into any typical calibration facility envi-  
ronment. The best results from the furnace are realized if the temperature fluc-  
tuations in the room are not excessive. A minimum of 18 inches free air space  
around the furnace must be allowed. This air space allows exchange to occur  
and safely remove heat from the furnace.  
WARNING: This furnace is intended for high temperature use and conse-  
quently a fire danger exists. DO NOT mount the furnace on a flammable  
surface and keep fire-extinguishing equipment near by.  
Extremely humid environments may require startup on low heat after long peri-  
ods of disuse.

“Dry-out” Period  
WARNING: Before initial use, after transport, and any time the instru-  
ment has not been energized for more than 10 days, the instrument needs  
to be energized for a “dry-out” period of 1-2 hours before it can be as-  
sumed to meet all of the safety requirements of the IEC 1010-1. If the  
product is wet or has been in a wet environment, take necessary measures  
to remove moisture prior to applying power such as storage in a low hu-  
midity temperature chamber operating at 50°C for 4 hours or more.

4.5  
Power  
The furnace utilizes a grounded AC supply of 230 VAC ( 10%), 20 amps, sin-  
gle phase, 50/60 HZ. An eight foot 2 conductor with ground, power cord is pro-  
vided. A separate ground connection is provided and required to permanently  
connect the instrument to earth ground for added operator safety.  
WARNING: Ensure accessability to the mains plug for disconnection  
from supply source.  
Equilibration Block Assembly Installation  
After the furnace has been installed and the permanent earth ground appropri-  
ately attached, the equilibration block assembly may be inserted. Carefully in-  
sert the block assembly into the tube with its insulation packing per Figure 1.  
Extreme care should be taken installing the Equilibration Block since it is very  
heavy and the fused silica tube is very fragile. A 1/8 to ¼ inch air gap between  
the front access plate and the front panel of the furnace is required in order to  
prevent the front panel from getting too hot. Care must be taken to prevent dirt,  
insulation, or anything else from getting between the block and the fused silica  
tube or it might break during heat up due to thermal expansion differences. The  
fit between the block and the tube is typically loose in order to accommodate  
this expansion.  
CAUTION: If the furnace must be moved for any reason, remove the  
block assembly to prevent breakage of the fused silica tube.  
4.6  
Probe Installation  
Install the temperature control and over temperature cutout probes from the as  
shown in Figure 1 and Figure 3. Insert the probes carefully to the depth shown  
in order to insure that the sensor is properly located in the equilibration block.  
The control probe should be inserted through the guard cover first so that the  
cover can be properly installed afterward. Position the rear guard block as

shown and then insert the insulation (ceramic fiber, see MSDS in the Appen-  
dix) being careful no to bend the probe sheath. The insulation should generally  
block air movement in and out of the back of the fused silica tube. Install the  
Guard Cover to prevent physical contact with parts that become dangerously  
hot when in use. Be sure to connect the probes properly on the rear panel.

two LED type displays. The upper display normally indicates the actual tem-  
perature while the lower display indicates the set temperature. The displays are  
also utilized in setup and alarm functions. Other indicators include the OP1 and  
OP2 indicator lights. The OP1 indicator lights when the heater is on. The OP2  
is not functional on the unit. The “R” indicator lights during programmed  
ramping. The “M” indicator flashes if the sensor fails. If the sensor opens, the  
heaters shut off.  
The up and down Temperature Adjustment arrow keys are the only temperature  
controls normally used. A quick single stroke increments or decrements the  
temperature setting. Holding the buttons down causes a gradual acceleration of  
the temperature setting. These same buttons are used to adjust other parameters  
in conjunction with the “PAR” button.  
Further information about the controller operation can be obtained from the  
temperature controller installation and operation manual included with the  
instrument.  
5.1.2  
Over Temperature Cutout  
The over temperature cutout is located at the left side of the control panel. The  
controls include a temperature limit adjustment control knob calibrated in Cel-  
sius and “limit exceeded” indicator light. The cutout is adjustable by the user  
within the temperature range of the furnace with divisions shown every 25°C.  
The indicator light turns on when the set limit is reached. The cutout can be set  
to Manual Reset or Auto Reset. The button on front panel allows the user to re-  
set the cutout. The unit leaves the factory with the unit set in the Manual Reset  
Mode. In the Auto Reset Mode, the temperature resets when it has dropped  
about 20 degrees.  
The cutout is provided to allow the user to set the maximum furnace tempera-  
ture to a point within the safe range of the sensor(s) being calibrated and to pro-  
tect the furnace from exceeding its own safe operating range. Limiting the top  
end also helps extend the life of the heaters.  
The cutout controls a relay which is wired in series with the heater circuit. The  
cutout is provided as a safety backup in case the solid state relay driven by the  
temperature controller fails (shorts) causing thermal runaway.  
5.1.3  
Power and Heater Switches  
The power switch is located just left of the temperature controller. The top is  
pressed inward to turn the unit on.  
Note: The internal fans are wired ahead of the switch so they stay on until  
the unit is cooled even though the main power may have been turned off.  
This way the outer surfaces of the enclosure are not heated to dangerous  
levels from stored heat.

Heater Assembly  
5.2  
Heater Assembly  
The heater is a made of fiber ceramic insulating material with imbedded heat-  
ing. The heater is made up with two halves, each with a separate heating ele-  
ment. The heating elements are wired in parallel.  
The heater is primarily a radiating device and is rated for a maximum furnace  
operating temperature of 1100°C. Realize, however, that the higher the operat-  
ing temperature, the lower the lifetime of the heater. Limiting the number of  
hours at the extreme high end of the temperature range to only the time re-  
quired for calibrations increases the longevity of your furnace heating element.

Equilibration Block Assembly  
The Equilibration Block Assembly consists of 1) the test well, 2) access tubes  
and end plate, 3) the front and rear guard blocks, 4) insulation on each end and  
5) the center block. The center block is intended to stabilize the temperature  
fluctuations and to conduct heat between the test wells in order to equalize  
them. The guard blocks shunt heat to the various probes to reduce heat loss out  
the ends. The whole assembly is supported by a fused silica tube. All heated  
materials are fused silica, ceramic fiber, or Inconel (alloy 600).

Temperature Control and Cutout Sensor  
The temperature control sensor is a Type K Thermocouple as indicated. This  
sensor is 3/16 inch in diameter and 12 inches long. Its location in the block is  
important and can cause the gradient in the block to move back and forth. The  
probe is normally inserted as shown in Figures 2 and 3.  
The cutout sensor is the same as the control sensor, 12 inches long. This sensor  
is inserted through a tube in the back of the block. Its location here helps pre-  
vent the heater elements from overheating thus prolonging their life.

Operation  
6.1  
Overview  
The Model 9112A is basically a temperature controlled furnace utilizing a full  
PID micro-processor based temperature controller with a Type K thermocouple  
temperature sensor. The temperature controller sends a time proportional signal  
to the solid state relay which regulates the current to the heater. The heater  
power can be switched to HIGH or LOW power positions. The object of the  
temperature control is the equilibration block with test wells containing the ref-  
erence probe and the sensors to be calibrated inside. The block provides a ther-  
mal mass which tends to stabilize the temperature and reduce the gradients  
between the test wells. The user settable “over-temperature cut-out” can open  
the heater circuit with a relay if the safe temperature for the test probe or for  
the furnace is exceeded. The enclosure is designed to limit the heat seen by the  
various components of the furnace as well as the user. The control section is in  
a separate cabinet below the furnace heat preventing damage or accuracy er-  
rors. The furnace part of the cabinet contains ventilation holes as well as two  
fans controlled by the thermostat. This cooling capability prevents the surface  
of the enclosure from getting dangerously hot. In the event that the fans should  
fail, a second thermostat is installed in the cabinet which shuts down the fur-  
nace heaters if the cabinet exceeds a safe temperature.  
6.2  
Operating the Furnace  
Operating the Model 9112A is straight forward once you have grasped all the  
important principles.  
When the unit is turned on, the cutout reset button must be pushed before the  
unit will heat.  
Temperature selection is accomplished by using the up and down arrow keys on  
the front of the temperature controller. The lower display indicates the new  
temperature setting while the upper display shows the actual temperature.  
When scanning from one temperature to another, notice that the temperature  
controller seems to be ahead of the equilibration block temperature. This differ-  
ence is because the temperature control sensor is near the outside of the block  
and it takes some time for the heat to conduct into the center. Depend on an ex-  
ternal temperature monitor to establish when the equilibration block has  
reached the desired temperature and achieved stability.  
The actual temperature indication made by the temperature controller is not in-  
tended to be a calibration reference, but to merely provide a general indication  
of the furnace temperature. NIST traceable standard thermometers are available  
and should be used in making comparison measurements. For less stringent  
measurements you may make a calibration of the controller and control probe  
at particular temperature points and use that with reasonable accuracy for a  
time.

CAUTION: Take care that all sensors used as references or being cali-  
brated in the furnace are capable of withstanding the desired temperature  
range to be used.  
WARNING:  
Take extreme care in handling hot probes. The ex-  
treme temperatures generated in a furnace of this type can cause serious  
personal injury. Do not touch them on external surfaces of the furnace or  
set them on any other surfaces unable to withstand those temperatures. A  
fire hazard exists. Do not touch the access tube end plate or severe burns  
can result.  
Some kind of metal and/or ceramic fiber surface or container should be used to  
set the hot probes on to prevent injury, damage, and fire.  
For best results, all reference or sample probes should be inserted into the full  
depth of the well. At this position the stability is the highest and the gradient  
the lowest. Each user should satisfy themselves as to what the uncertainties are  
in terms of stability and gradients between the test wells. Variations in equip-  
ment, probe size, configuration, etc affect these important factors. A solid  
(unstirred) mass such as in a furnace is subject to heat losses from the probe  
stem which varies from probe to probe and temperature to temperature. Typi-  
cally, stabilities are less than 0.1°C and can be as little as 0.015°C at 500°C.  
Similarly, gradients between the measuring cells can range from 0.2°C to well  
under 0.1°C. For calibrations that must be less than full insertion into the test  
well, make your own comparisons between the reference and test cell at that  
depth to establish the uncertainties.  
The furnace can be used throughout the temperature range of 300 to 1100°C.  
Lower temperatures are sluggish however. High integrating values are required  
to maintain controller stability (1200 sec) at the lower temperatures. Expect  
some offset from the indicated temperature and the actual temperature. Stability  
and gradients between test wells are similar at higher temperatures but time to  
stability is much longer.

Maintenance  
The calibration instrument has been designed with the utmost care. Ease of op-  
eration and simplicity of maintenance have been a central theme in the product  
development. Therefore, with proper care the instrument should require very  
little maintenance. Avoid operating the instrument in an oily, wet, dirty, or  
dusty environment.  
If the outside of the instrument becomes soiled, it may be wiped clean  
with a damp cloth and mild detergent. Do not use harsh chemicals on the  
surface which may damage the paint.  
Be sure that the well of the furnace is kept clean and clear of any foreign  
matter. Do not use fluids to clean out the well.  
If a hazardous material is spilt on or inside the equipment, the user is re-  
sponsible for taking the appropriate decontamination steps as outlined by  
the national safety council with respect to the material.  
If the mains supply cord becomes damaged, replace it with a cord with  
the appropriate gauge wire for the current of the instrument. If there are  
any questions, call Hart Scientific Customer Service for more informa-  
tion.  
Before using any cleaning or decontamination method except those rec-  
ommended by Hart, users should check with Hart Scientific Customer  
Service to be sure that the proposed method will not damage the equip-  
ment.  
If the instrument is used in a manner not in accordance with the equip-  
ment design, the operation of the furnace may be impaired or safety haz-  
ards may arise.  
The over-temperature cut-out should be checked every 6 months to ensure  
that it is working properly. Set the unit to 300°C and let it stabilize. Turn  
the adjustable cutout knob down until the cutout is activated. Turn the  
knob back up and push the reset button.  
Periodically remove the equilibration block and use emery cloth to re-  
move the oxidation build up on the block.

EMERGENCY OVERVIEW  
WARNING!  
 
POSSIBLE CANCER HAZARD BY INHALATION.  
(See Section 11 for more information)  
CHRONIC EFFECT  
There has been no increased incidence of respiratory disease in studies examining occupationally exposed  
workers. In animal studies, long-term laboratory exposure to doses hundreds of times higher than normal  
occupational exposures has produced fibrosis, lung cancer, and mesothelioma in rats or hamsters. The fibers  
used in those studies were specially sized to maximize rodent respirability.  
OTHER POTENTIAL EFFECTS  
TARGET ORGANS:  
Respiratory Tract (nose & throat), Eyes, Skin  
RESPIRATORY TRACT (nose & throat) IRRITATION:  
If inhaled in sufficient quantity, may cause temporary, mild mechanical irritation to respiratory tract.  
Symptoms may include scratchiness of the nose or throat, cough or chest discomfort.  
EYE IRRITATION:  
May cause temporary, mild mechanical irritation. Fibers may be abrasive; prolonged contact may cause  
damage to the outer surface of the eye.  
SKIN IRRITATION:  
May cause temporary, mild mechanical irritation. Exposure may also result in inflammation, rash or itching.  
GASTROINTESTINAL IRRITATION:  
Unlikely route of exposure.  
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:  
Pre-existing medical conditions, including dermatitis, asthma or chronic lung disease may be aggravated by  
exposure; individuals who have a history of allergies may experience greater amounts of skin and  
respiratory irritation.  
HAZARD CLASSIFICATION  
Although studies, involving occupationally exposed workers, have not identified any increased incidence of  
respiratory disease, results from animal testing have been used as the basis for hazard classification. In each of  
the following cases, the conclusions are qualitative only and do not rest upon any quantitative analysis suggesting  
that the hazard actually may occur at current occupational exposure levels.

FIRST AID PROCEDURES  
RESPIRATORY TRACT (nose & throat) IRRITATION:  
If respiratory tract irritation develops, move the person to a dust free location. Get medical attention if the irritation  
continues. See Section 8 for additional measures to reduce or eliminate exposure.  
EYE IRRITATION:  
If eyes become irritated, flush immediately with large amounts of lukewarm water for at least 15 minutes. Eyelids  
should be held away from the eyeball to ensure thorough rinsing. Do not rub eyes. Get medical attention if  
irritation persists.  
SKIN IRRITATION:  
If skin becomes irritated, remove soiled clothing. Do not rub or scratch exposed skin. Wash area of contact  
thoroughly with soap and water. Using a skin cream or lotion after washing may be helpful.  
GASTROINTESTINAL IRRITATION:  
If gastrointestinal tract irritation develops, move the person to a dust free environment.  
NOTES TO PHYSICIANS:  
Skin and respiratory effects are the result of temporary, mild mechanical irritation; fiber exposure does not result  
in allergic manifestations.

dry sweeping should not be used for cleaning.  
7. HANDLING AND STORAGE  
STORAGE  
Store in original container in a dry area. Keep container closed when not in use.  
HANDLING  
Handle ceramic fiber carefully. Limit use of power tools unless in conjunction with local exhaust. Use hand tools  
whenever possible. Frequently clean the work area with HEPA filtered vacuum or wet sweeping to minimize the  
accumulation of debris. Do not use compressed air for clean-up.  
EMPTY CONTAINERS  
Product packaging may contain residue. Do not reuse.

There is no specific regulatory standard for RCF in the U.S. OSHA’s “Particulate Not Otherwise Regulated  
*
(PNOR)” standard [29 CFR 1910.1000, Subpart Z, Air Contaminants] applies generally; Total Dust 15 mg/m³;  
Respirable Fraction 5 mg/m³.  
** The Refractory Ceramic Fibers Coalition (RCFC) has sponsored comprehensive toxicology and epidemiology  
studies to identify potential RCF-related health effects [see Section 11 for more details], consulted experts familiar  
with fiber and particle science, conducted a thorough review of the RCF-related scientific literature, and further  
evaluated the data in a state-of-the-art quantitative risk assessment. Based on these efforts and in the absence of  
an OSHA PEL, RCFC has adopted a recommended exposure guideline, as measured under NIOSH Method  
7400 B. The manufacturers’ REG is intended to promote occupational health and safety through prudent  
exposure control and reduction and it reflects relative technical and economic feasibility as determined by  
extensive industrial hygiene monitoring efforts undertaken pursuant to an agreement with the U.S. Environmental  
Protection Agency.  
OTHER OCCUPATIONAL EXPOSURE LEVELS (OEL)  
RCF-related occupational exposure limits vary internationally. Regulatory OEL examples include: Australia – 0.5  
f/cc; Austria – 0.5 f/cc; Canada – 0.5 to 1.0 f/cc; Denmark – 1.0 f/cc; France – 0.6 f/cc; Germany – 0.5 f/cc;  
Netherlands – 1.0 f/cc; New Zealand – 1.0 f/cc; Norway – 2.0 f/cc; Poland – 2.0 f/cc; Sweden – 1.0 f/cc; United  
Kingdom – 2.0 f/cc. Non-regulatory OEL examples include: ACGIH TLV 0.2 f/cc; RCFC REG 0.5 f/cc. The  
 
objectives and criteria underlying each of these OEL decisions also vary. The evaluation of occupational exposure  
limits and determining their relative applicability to the workplace is best performed, on a case-by-case basis, by a  
qualified Industrial Hygienist.  
ENGINEERING CONTROLS  
Use engineering controls such as local exhaust ventilation, point of generation dust collection, down draft work  
stations, emission controlling tool designs, and materials handling equipment designed to minimize airborne fiber  
emissions.  
PERSONAL PROTECTION EQUIPMENT  
Respiratory Protection – RCF:  
When engineering and/or administrative controls are insufficient to maintain workplace concentrations within the  
0.5 f/cc REG, the use of appropriate respiratory protection, pursuant to the requirements of OSHA Standards 29  
CFR 1910.134 and 29 CFR 1926.103, is recommended. The following information is provided as an example of  
appropriate respiratory protection for aluminosilicate fibers. The evaluation of workplace hazards and the  
identification of appropriate respiratory protection is best performed, on a case by case basis, by a qualified  
Industrial Hygienist.

with 29 CFR 1910.134.  
Other Information:  
Concentrations based upon an eight-hour time weighted average (TWA) as determined by air samples  
collected and analyzed pursuant to NIOSH method 7400 (B) for airborne fibers.  
The manufacturer recommends the use of a full-facepiece air purifying respirator equipped with an  
appropriate particulate filter cartridge during furnace tear-out events and the removal of used RCF to  
 
control exposures to airborne fiber and the potential presence of crystalline silica. If exposure levels are  
known, the respiratory protection chart provided above may be applied.  
Potential exposure to other airborne contaminants should be evaluated by a qualified Industrial Hygienist  
for the selection of appropriate respiratory protection and air monitoring.  
Skin Protection:  
Wear gloves, head coverings and full body clothing as necessary to prevent skin irritation. Washable or  
disposable clothing may be used. If possible, do not take unwashed clothing home. If soiled work clothing must be  
taken home, employers should ensure employees are thoroughly trained on the best practices to minimize or  
avoid non-work dust exposure (e.g., vacuum clothes before leaving the work area, wash work clothing separately,  
rinse washer before washing other household clothes, etc.).  
Eye Protection:  
Wear safety glasses with side shields or other forms of eye protection in compliance with appropriate OSHA  
standards to prevent eye irritation. The use of contact lenses is not recommended, unless used in conjunction  
with appropriate eye protection. Do not touch eyes with soiled body parts or materials. If possible, have eye-  
washing facilities readily available where eye irritation can occur.

11. TOXICOLOGICAL INFORMATION  
HEALTH DATA SUMMARY  
Epidemiological studies of RCF production workers have indicated no increased incidence of respiratory  
disease nor other significant health effects. In animal studies, long-term, high-dose inhalation exposure  
resulted in the development of respiratory disease in rats and hamsters.  
EPIDEMIOLOGY  
 
The University of Cincinnati is conducting an ongoing epidemiologic investigation. The evidence obtained from  
employees in U. S. RCF manufacturing facilities is as follows:  
1) There is no evidence of any fibrotic lung disease (interstitial fibrosis) from evaluations of chest X-rays.  
2) There is no evidence of an elevated incidence of lung disease among RCF manufacturing employees.  
3) In early studies, an apparent statistical “trend” was observed, in the exposed population, between RCF  
exposure duration and some measures of lung function. The observations were clinically insignificant. If these  
observations were made on an individual employee, the results would be interpreted as being within the normal  
(predicted) respiratory range. A more recent longitudinal study of employees with 5 or more pulmonary function  
tests found that there was no effect on lung function associated with RCF production experience. Initial data (circa  
1987) seemed to indicate an interactive effect between smoking and RCF exposure; more recent data, however,  
found no interactive effect. Nevertheless, to promote good health, RCF employees are still actively encouraged  
not to smoke.  
4) Pleural plaques (thickening along the chest wall) have been observed in a small number of RCF employees.  
Some studies appear to show a relationship between the occurence of pleural plaques on chest radiographs and  
the following variables: (a) years since RCF production hire date; (b) duration of RCF production employment;  
and (c) cumulative RCF exposure. The best evidence to date indicates that pleural plaques are a marker of  
exposure only. Pleural plaques are not associated with pulmonary impairment. The pathogenesis of pleural  
plaques remains incompletely understood; however, the mechanism appears to be an inflammatory response  
caused by inhaled fibers.  
TOXICOLOGY  
A number of toxicological studies designed to identify any potential health effects from RCF exposure have been  
completed. In one study, conducted by the Research and Consulting Company, (Geneva, Switzerland), rats and  
hamsters were exposed to 30 mg/m³ (about 200 fibers/cc) of specially-prepared RCF for 6 hours/day, 5  
days/week, for up to 24 months. In rats, a statistically significant increase in lung tumors was observed; two  
mesotheliomas (cancer of the pleural lining between the chest wall and lung) were also identified. Hamsters did  
not develop lung tumors; however, interstitial fibrosis and mesothelioma was found. Some, in the scientific  
community, have concluded that the “maximum tolerated dose” was exceeded and that significant particle  
contamination was a confounding issue; therefore, these study findings may not represent an accurate  
assessment of the potential for RCF to produce adverse health effects.  
In a related multi-dose study with a similar protocol, other rats were exposed to doses of 16 mg/m³, 9 mg/m³, 3  
mg/m³ which corresponds to about 115, 75, and 25 fibers per cubic centimeter respectively. This study found no  
statistically significant increase in lung cancer. Some cases of pleural and parenchymal fibrosis were seen in the  
16 mg/m³ dose group. Some cases of mild fibrosis and one mesothelioma were observed in the 9 mg/m³ group.  
No acute respiratory effects were seen in the rats in the 3 mg/m³ exposure group, which suggests that there may  
be a dose/response threshold, below which irreversible respiratory impacts do not occur.  
Other toxicological studies have been conducted which utilized non-physiological exposure methods such as  
intrapleural, intraperitoneal and intratracheal implantation or injection. Some of these studies have found that RCF  
is a potential carcinogen. Some experts, however, suggest that these tests have limited relevance because they  
bypass many of the biological mechanisms that prevent fiber deposition or facilitate fiber clearance.

16. OTHER INFORMATION  
RCF DEVITRIFICATION  
As produced, all RCF fibers are vitreous (glassy) materials which do not contain crystalline silica. Continued  
exposure to elevated temperatures may cause these fibers to devitrify (become crystalline). The first crystalline  
formation (mullite) begins to occur at approximately 985° C (1805° F). Crystalline silica (cristobalite) formation  
may begin at temperatures of approximately 1200° C (2192° F). The occurrence and extent of crystalline phase  
formation is dependent on the duration and temperature of exposure, fiber chemistry and/or the presence of  
fluxing agents. The presence of crystalline phases can be confirmed only through laboratory analysis of the "hot  
face" fiber.  
IARC’s evaluation of crystalline silica states “Crystalline silica inhaled in the form of quartz or cristobalite from  
occupational sources is carcinogenic to humans (Group 1)” and additionally notes “carcinogenicity in humans was  
not detected in all industrial circumstances studied” (IARC Monograph Vol. 68, 1997). NTP lists all polymorphs of  
crystalline silica amongst substances which may "reasonably be anticipated to be carcinogens".  
IARC and NTP did not evaluate after-service RCF, which may contain various crystalline phases. However, an  
analysis of after-service RCF samples obtained pursuant to an exposure monitoring agreement with the USEPA,  
found that in the furnace conditions sampled, most did not contain detectable levels of crystalline silica. Other  
relevant RCF studies found that (1) simulated after-service RCF showed little, or no, activity where exposure was  
by inhalation or by intraperitoneal injection; and (2) after-service RCF was not cytotoxic to macrophage-like cells  
at concentrations up to 320 g/cm² - by comparison, pure quartz or cristobalite were significantly active at much  
lower levels (circa 20 g/cm²).  
RCF AFTER-SERVICE REMOVAL  
Respiratory protection should be provided in compliance with OSHA standards. During removal operations, a full  
face respirator is recommended to reduce inhalation exposure along with eye and respiratory tract irritation. A  
specific evaluation of workplace hazards and the identification of appropriate respiratory protection is best  
performed, on a case by case basis, by a qualified industrial hygiene professional.  
PRODUCT STEWARDSHIP PROGRAM  
The Unifrax Corporation has established a program to provide customers with up-to-date information regarding  
the proper use and handling of refractory ceramic fiber. In addition, Unifrax Corporation has also established a  
program to monitor airborne fiber concentrations at customer facilities. If you would like more information about  
 
this program, please call the Unifrax Corporation Product Stewardship Information Hotline at 1-800-322-2293.  
On February 11, 2002, the Refractory Ceramic Fibers Coalition (RCFC) and the U.S. Occupational Safety and

If respiratory tract irritation develops, move the person to a dust free location. See Section 8 for additional measures to  
reduce or eliminate exposure.  
EYE IRRITATION  
If eyes become irritated, flush immediately with large amounts of lukewarm water for at least 15 minutes. Eyelids  
should be held away from the eyeball to ensure thorough rinsing. Do not rub eyes.  
SKIN IRRITATION  
If skin becomes irritated, remove soiled clothing. Do not rub or scratch exposed skin. Wash area of contact  
thoroughly with soap and water. Using a skin cream or lotion after washing may be helpful.  
GASTROINTESTINAL IRRITATION  
If gastrointestinal tract irritation develops, move the person to a dust free environment.  
- If symptoms persist, seek medical attention. -  
NOTE TO PHYSICIANS

8. EXPOSURE CONTROLS/PERSONAL PROTECTION  
MANUFACTURER'S RECOMMENDATION  
It is prudent to reduce exposure to respirable dusts to the lowest attainable level through the use of engineering controls  
such as ventilation and dust collection devices. Industrial hygiene standards and occupational exposure limits may vary  
between countries, state and local jurisdictions. Contact your employer to determine which exposure levels apply to  
your facility. If no regulatory dust or other standards apply, a qualified industrial hygienist can assist with a specific  
workplace evaluation including recommendations for respiratory protection. In the absence of such guidance, the  
manufacturer generally recommends the control of CMS wool exposures to 1 fiber/cc or less.  
ENGINEERING CONTROLS  
Use feasible engineering controls such as local exhaust ventilation, point of generation dust collection, down draft work  
stations, emission controlling tool designs, and materials handling equipment designed to minimize airborne fiber  
emissions.  
PERSONAL PROTECTION EQUIPMENT  
Skin Protection  
Wear gloves, head coverings and full body clothing as necessary to prevent skin irritation. Washable or disposable  
clothing may be used. If possible, do not take unwashed work clothing home. If soiled work clothing must be taken  
home, employers should ensure employees are trained on the best practices to minimize or avoid non-work dust  
exposure (e.g., vacuum clothes before leaving the work area, wash work clothing separately, rinse washer before  
washing other household clothes, etc.).  
Eye Protection  
Wear safety glasses with side shields or other forms of eye protection in compliance with appropriate OSHA standards  
to prevent eye irritation. The use of contact lenses is not recommended, unless used in conjunction with appropriate  
eye protection. Do not touch eyes with soiled body parts or materials. If possible, have eye-washing facilities readily  
available where eye irritation can occur.  
Respiratory Protection  
When it is not possible or feasible to reduce respirable dust exposures through engineering controls, employees are  
encouraged to use good work practices together with respiratory protection. Comply with OSHA Respiratory Protection  
Standards, 29 CFR 1910.134 and 29 CFR 1926.103, for the particular hazard or airborne concentrations to be  
encountered in the work environment. For the most current information on respirator selection, contact your supplier.

11. TOXICOLOGICAL INFORMATION  
TOXICOLOGY  
CMS wools have been tested for their biopersistence using methods devised by the European Union. The results from  
these studies exonerate CMS wools from carcinogen classification under the criteria listed in Nota Q of European  
Commission Directive 97/69/EU.  
In a lifetime carcinogenicity test, rats were exposed by inhalation for two years (5 days a week; 6 hours a day) to CMS  
fibers at 200 WHO fibers/ml. There was neither fibrosis nor carcinogenic response; only reversible cellular changes  
were seen. Further, subchronic inhalation studies on rats with CMS fibers at concentrations of 150 fibers (>20 µm long)  
per ml for 90 days with follow up to 1 year showed neither inflammation nor cell proliferation. All parameters studied  
returned rapidly to baseline levels on cessation of exposure.  
After-service, CMS wools may contain crystalline phases including some forms of silica. (See Section 16) However,  
CMS fibers heated to 1000°C for 2 weeks were not cytotoxic to macrophage-like cells at concentrations up to 320  
µg/cm2. In the same test, samples of pure crystalline quartz were significantly active at 20 µg/cm2.  
EPIDEMIOLOGY  
This material has not been the subject of an epidemiology study.  
NOTE  
Neither the International Agency for Research on Cancer (IARC) nor the National Toxicology Program nor any other  
U.S. regulatory or classification entity has evaluated CMS wool. Superwool products are members of a family of  
materials whose properties are distinct in several ways from other man-made mineral fibers. In October 2001 IARC re-  
reviewed Man-Made Vitreous Fibers and “elected not to make an overall evaluation of the newly developed fibers” [such  
as CMS wool] but recognized that “those that have been tested appear to have low carcinogenic potential in  
experimental animals.”  
While CMS wool is an inert material that does not react with the skin, exposures may cause temporary mild mechanical  
irritation to the eyes, skin, nose and/or throat (for First Aid Measurers, see Section 4). Proper handling practices and  
the use of protective clothing (see Section 8) can minimize irritation.  
12. ECOLOGICAL INFORMATION  
No adverse effects of this material on the environment are anticipated.  
13. DISPOSAL INFORMATION  
WASTE MANAGEMENT  
To prevent waste materials becoming airborne, a covered container or plastic bagging is recommended.

CMS wool, as manufactured, is not classified as a hazardous waste according to Federal regulations (40 CFR 261). As  
manufactured, CMS wool was tested using EPA's Toxicity Characteristics Leaching Procedure (TCLP). Results  
showed there were no detectable contaminants or detectable leachable contaminants that exceeded the regulatory  
levels. Any processing, use, alteration or chemical additions to the product, as purchased, may alter the disposal  
requirements. Under Federal regulations, it is the waste generator's responsibility to properly characterize a waste  
material, to determine if it is a "hazardous" waste. Check local, regional, state or provincial regulations to identify all  
applicable disposal requirements.

16. OTHER INFORMATION  
SUPERWOOLTM DEVITRIFICATION  
As produced, SuperwoolsTM are vitreous (glassy) AES Wools that do not contain crystalline silica. Continued exposure  
to elevated temperatures (>9000C) may cause these materials to form crystalline phases, including crystalline silica.  
The occurrence and extent of crystalline silica formation is dependent on the duration and temperature of exposure,  
CMS Wool chemistry and/or the presence of fluxing agents. The presence of crystalline silica can be confirmed only  
through laboratory analysis of the "hot face" fiber. If crystalline silica is present, follow appropriate hygiene standards  
and national regulations.  
Devitrified, after-service SuperwoolTM, containing crystalline silica, has shown no adverse reactions in toxicity assays  
(See Section 11). These findings are consistent with IARC’s evaluation, which states “Crystalline silica inhaled in the  
form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1)” and additionally notes  
“carcinogenicity in humans was not detected in all industrial circumstances studied. Carcinogenicity may be dependent  
on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution of  
its polymorphs.” (IARC Monograph Vol. 68, 1997).  
Respirable dust from devitrified SuperwoolTM products can be controlled with ventilation, dust collectors or respiratory  
protection as detailed in Section 8 (above). Ventilation and respiratory protection should be provided in compliance with  
OSHA standards. The evaluation of workplace hazards and, if necessary, the identification of appropriate respiratory  
protection is best performed by qualified Industrial Hygienists.  
For more information, call the Thermal Ceramics Product Stewardship Hotline (800-722-5681).
