1 Before You Start

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 cor­rectly 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 tempera­ture 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.

2 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 pos­sibility of thermal runaway due to a shorted solid-state relay which controls the
heaters.

4.2 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.

4.3 “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.

4.4 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.

4.5 Equilibration Block Assembly Installation

After the furnace has been installed and the permanent earth ground appropri­ately attached, the equilibration block assembly may be inserted. Carefully in­sert 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 Cel­sius 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 re­set 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 tempera­ture 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.

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).

5.2.2 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.

6 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 fur­nace 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.

9112A Calibration Furnace

User’s Guide

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 equip­ment, 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. Typi­cally, 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.

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.

** 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

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.

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,

4. FIRST AID MEASURES

RESPIRATORY TRACT (nose and throat) IRRITATION

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

Skin and respiratory effects are the result of temporary, mild mechanical irritation; fiber exposure does not result in
allergic manifestations.

6. ACCIDENTAL RELEASE MEASURES

SPILL PROCEDURES

Avoid creating airborne dust. Dust suppressing cleaning methods such as wet sweeping or vacuuming should be used
to clean the work area. If vacuuming, the vacuum should be equipped with a HEPA filter. Compressed air or dry
sweeping should not be used for cleaning.

7. HANDLING AND STORAGE

STORAGE

Store in original factory container in a dry area. Keep container closed when not in use.

HANDLING

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

Do not reuse the container.

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

2

µg/cm

. 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 re­reviewed 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.

MSDS No: 350 Date Prepared: 03/24/1992 Current Date: 7/26/2002

RCRA

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.

SUPERWOOLTM DEVITRIFICATION

As produced, Superwools
to elevated temperatures (>900
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 Superwool
(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).
