5.3 Exhaust Vent
Flow from the exhaust vent on the top of the unit can be adjusted
by inserting or removing the plug provided.
For most applications, the exhaust vent should be fully plugged
during operation
of the furnace; a closed vent results in more
efficient operation and greater temperature stability. However,
there are some applications which benefit from a partially or
fully open exhaust vent.
The exhaust vent should be partially or fully open for the
following applications:
• To provide slow cool down of work load. Some work loads
may be damaged by heat shock when the furnace door is
opened. The vent can
be opened to allow work load to cool
gradually.
• To remove unwanted vapors and gases from the furnace
chamber.
If
you need to ventilate vapors and gases outside of
the room, be sure to read Section 5.4.
Figure 2 shows
how you can use the plug to adjust flow from the
exhaust vent.

Port tube
Outer cabinet
Figure 2. Exhaust Vents
5.4 Exhaust Port Connections
Vent closed
The one inch diameter exhaust port through the top wall of the
furnace allows for
the removal of unwanted vapors and gases
produced during high-temperature operation.
When you need to ventilate vapors and gases outside of the
room, be sure to make a proper connection to the exhaust port
that allows some room air to flow into the hood or pipe. This is
necessary
to prevent "chimney effect" which sucks heat out of
the chamber and results in slow run-up time or poor temperature
uniformity.
Two methods
of making the exhaust port connection are shown
in Figure 3 below. With a hood suspended above the furnace, be
sure that there is at least three inches between the hood and the
exhaust port.
If
you use a metal tube or pipe leave at least one
inch clearance.

V. HEALTH HAZARDS
A. Health: WARNING! MAY BE IRRITATING TO SKIN, EYES, AND RESPIRATORY TRACT. MAY
BE HARMFUL IF INHALED. POSSIBLE CANCER HAZARD BY INHALATION. Contains
refractory ceramic fibers which MAY CAUSE CANCER BASED ON ANIMAL DATA. Risk
of cancer depends on duration and level of exposure. (See Section X. for information
concerning additional hazards after high temperature operation.)
B. Ingestion: Ingestion is unlikely. If ingested in sufficient quantity, may cause gastrointestinal
disturbances. Symptoms may include irritation, nausea, vomiting, abdominal pain and
diarrhea.
C. Skin: Slightly to moderate irritating. May cause irritation, inflammation, and rash.
D. Eye: Slightlyto moderate irritating. Abrasive action may cause damage to the outer surface of
the eye.
E. Inhalation: May irritate respiratory tract. Pre-existing medical conditions, especially chronic
bronchial or lung disease may be aggravated by exposure.
F. Toxicity: Existing toxicology and epidemiology data are preliminary and the results presented
below have not been validated by scientific review.
G. Epidemiology:
There are no known published reports of negative health affects of workers exposed to
refractory ceramic fibers (RCFs). Studies of RCF production workers continues.
Preliminary evidence, reportedly obtained from employees in RCF manufacturing
facilities, indicates the following:
1. There is no evidence on x-rays of any fibrotic lung disease of RCF manufacturing
employees.
2. There is no evidence of any lung disease among those employees exposed to RCF
that never smoked.
3. A statistical trend of slightly decreased pulmonary function was observed in the
exposed population of workers based on the duration of RCF exposure. The statistic
showing decreased pulmonary function was within the normal range and/or was
insignificant.

Pleural plaques (thickening along the chest wall) have been observed in a small number
of employees who had a long duration of employment. There are several occupational
and non-occupational causes for pleural plaque. Plaques are not "pre-cancer" nor are
they associated with any measurable effect on lung function.
H. Toxicology: Several health effect studies of inhalation exposure of rats and hamsters are now
reaching completion. In a lifetime nose-only inhalation study, rats exposed to a very high
dose of 30 mg/m3 (200 fibers/cc) developed progressive lung damage (interstitial
fibrosis) and cancers of the lung and of the pleura (lining of the chest wall and lung).
In
contrast, hamsters similarly exposed developed interstitial fibrosis and pleural cancer,
but no lung cancer. Cancer of the pleura is called mesothelioma.
A multiple dose study
{3, 9, 16 mg/m3 or 25, 75, 150 fibers/cc, respectively) is currently
ongoing
in rats. After 24 months of exposure, only reversible cellular changes have been
seen
in the low dose group. At 9 mg/m3 (75 fibers/cc), areas of lung fibrosis are barely
discernible and at 16 mg/m3 (150 fibers/cc) both lung and pleural fibrosis are present.
At this time,
no lung or pleural cancer has been seen in the multiple dose study. This
information will be updated once the study is completed.
In 1987, the International Agency for Research on Cancer {IARC) reviewed the
carcinogenicity data on man-made vitreous fibers (including ceramic fiber, glasswool,
rockwool, and slagwool). IARC classified ceramic fiber, fibrous glasswool and mineral
wool (rockwool and slagwool) as possible human carcinogens (Group 28).
VI. EMERGENCY AND FIRST AID PROCEDURES
Ingestion: Drink extra water. Allow for natural gastrointestinal elimination. Get medical attention if
gastrointestinal symptoms develop (see Section
V.).
Skin Contact: Remove contaminated clothing. Wash affected skin thoroughly with soap and water. Do
not rub or scratch exposed skin. A skin cream or lotion used after washing may be
helpful. Seek medical attention if irritation persists.
Eye Contact: Immediately rinse eyes with water. Remove any contact lenses, and continue flushing
eyes with running water for at least 15 minutes. Do not rub eyes. Hold eyelids apart to
ensure rinsing of the entire surface of eyes and lids with water. Get immediate medical
attention.
Inhalation: Remove exposed person to fresh air. Seek medical attention if shortness of breath,
cough, wheezing, or chest pain develop. If breathing is labored, administer oxygen until
medical assistance can be rendered.
VII. PERSONAL PROTECTIVE EQUIPMENT
Eyes: Wear safety glasses or chemical goggles. Contact lenses should not be worn unless
chemical goggles are also used and care is taken to not touch the eyes with
contaminated body parts or materials.
Skin: Wear gloves, hats and full body covering to prevent skin irritation as necessary (see
Section X.).

Respiratory Use of properly designed and operating engineering controls is recommended and
Protection:
preferred over respiratory protection for controlling airborne dust and fiber
concentrations.
If exposures exceed our Recommended Exposure Limit (REL} of 1.0 fiberslcc of air
(8 hour TWA) respiratory protection as outlined below must be used. Also, use
respiratory protection if throat irritation is experienced. When airborne concentrations
are unknown or exceed 0.5 flee, use of a half face respirator described below is
recommended. Respiratory protection is necessary if the material has been exposed to
temperatures at or above 1800°F. (See Section X.). Use only NIOSHIMSHA approved
respirators.
Concentration (8 hour TWA) Minimum Acceptable Respirator Type
0 to 0.5 flee Optional disposable dust respirator
0.5 flee to 5 flee or up to 10 times the OSHA Half face, air-purifying respirator equipped with high-efficiency
PEL for cristobalite particulate air (HEPA) filter cartridges
5 to 25
flee
or up to 50 times the OSHA PEL for Full face, air-purifying respirator with high-efficiency particulate
cristobalite air (HEPA) filter cartridges or powered air-purifying respirator
(2.5 mglm3) (PAPR) equipped with HEPA filter cartridges
Greater than 25 flee or 50 times the OSHA Full face, positive pressure supplied air respirator
PEL for cristobalite (2.5 mglm3)
As minimum protection, use half-mask air-purifying respirators equipped with HEPA filter cartridges if airborne
fiber levels or cristobalite concentrations are not known.
PLEASE NOTE:
Employees must be given instruction, fit testing, medical evaluation, and training per 29 CFR 1910.134 and your
company's written respirator program if respiratory protection is used. Appropriate respirator selection must be a
part of the respirator program. The above respirator recommendations are general guidelines only and may not
be appropriate for certain applications. Please consult with your safety or industrial hygiene staff or consultants.

Moldatherm® Insulation Material Safety Data Sheet
Product which has been in service at elevated temperatures (at or above 1800°F) over
time may undergo partial conversion to cristobalite, a form of crystalline silica. This
reaction occurs at the furnace lining hot face. As cristobalite is formed, Moldatherm®
insulation becomes more friable; special caution must be taken to minimize generation
of airborne dust. The amount of cristobalite formed will vary based on the operating
temperature and length of service. (The IARC classification for crystalline silica is a
group 2A carcinogen (probable human carcinogen). Cristobalite (crystalline silica) is
also listed by NTP as a carcinogen).
WARNING! DUST CAN CAUSE SEVERE RESPIRATORY DISEASE. DUST MAY BE
IRRITATING TO SKIN, EYES, AND RESPIRATORY TRACT. SUSPECT CANCER
HAZARD BY INHALATION. Cristobalite (crystalline silica) MAY CAUSE CANCER.
The OSHA permissible exposure limit (PEL) and the ACGIH threshold limit value (TLV)
for cristobalite is 0.05 mg/m3 (respirable dust). Use NIOSH/MSHA approved respirators
when airborne exposure limits may be exceeded. (See Section VII. table for respirator
selection.)
Insulation surfaces should
be lightly sprayed with water before removal to suppress
airborne dust. Spray additional water as water evaporates during removal. A surfactant
may aid the wetting process.
After removal of the Moldatherm® insulation
is complete, dust suppressing cleaning
methods, such as wet sweeping or vacuuming should be used to clean the work area. If
dry vacuuming is used, the vacuum must be equipped with a HEPA filter. Air blowing or
dry sweeping should not be used. Dust suppressing components can be used to clean
up light dust.
Do not reuse product packaging because of possible product residue.
