a. OSHA has not established a specific PEL for fibrous silicone dioxide (amorphous silica) or fibrous
glass. It is considered to be a "particulate not otherwise regulated" (PNOR) and is covered under the
OSHA nuisance dust PEL's of 5 mg/m3 for the respirable dust fraction and 15 mg/m3 for the total
dust fraction for an 8-hr TWA (Time Weighted Average). Chemically, AMI-SIL庐 is amorphous
silica which has an OSHA limit of 20 mppcf or 80 mg/m3.
3. HAZARDS IDENTIFICATION

3. HAZARDS IDENTIFICATION (CON'T)
ACUTE: Inhalation: Inhalation of dusts and fibers may result in irritation of the upper
respiratory tract (mouth, nose and throat).
Skin Contact: Skin contact with dusts and fibers may produce itching and
temporary mechanical irritation.
Eye Contact: Eye contact with fibers and dusts may produce temporary
mechanical irritation.
Ingestion: Temporary mechanical irritation of the digestive tract. Observe
individual. If symptoms develop, consult a physician.
CHRONIC: See carcinogenicity section below. There are no known health effects associated
with chronic exposure to this product.
CARCINOGENICITY:
Hazardous Ingredients: Listed as carcinogen by: ACGIH IARC NTP OSHA
Silicone dioxide, NA NA NA NA
continuous filament
Fiberglass continuous filament No No* No No
*IARC: In June, 1987 the International Agency for Research on Cancer (IARC) categorized
fiberglass continuous filaments as not classifiable with respect to human carcinogenicity (Group
3). The evidence from human as well as animal studies was evaluated by IARC as insufficient to
classify fiberglass continuous filaments as a possible, probable, or confirmed cancer causing
material.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Persons with a history of chronic
respiratory or skin conditions that are aggravated by mechanical irritants may be at increased risk for
worsening their condition from exposure during use of the product.
4. FIRST AID MEASURES
Inhalation: Move individual to fresh air. Seek medical attention if irritation persists.
Skin Contact: Wash with mild soap and running water. Use a washcloth to help remove fibers. To
avoid further irritation do not rub or scratch irritated areas. Rubbing or scratching may
force fibers into the skin. Seek medical attention if irritation persists.

4. FIRST AID MEASURES (CON鈥橳)
Eye Contact: Flush eyes with flowing water for at least 15 minutes. Seek medical attention if irritation
persists.
Ingestion: N. A. (Not Applicable)
5. FIRE FIGHTING MEASURES
Flash Point (oF): NA (Not Applicable)
Auto Ignition Temperature (oF): NA
Flammability Limits (%): LEL: NA UEL: NA
Extinguishing Media: Water, foam, carbon dioxide, dry chemical
Special Fire-Fighting Instructions: In a sustained fire, self contained breathing apparatus should be
worn.
Unusual Fire and Explosion Hazards: None known.
6. ACCIDENTAL RELEASE MEASURES
ACTION TO TAKE FOR SPILLS (Use Appropriate Safety Equipment): For solid product, not
applicable. For dusts and fibers generated during fabrication vacuum up and containerize.
7. HANDLING, STORAGE AND DISPOSAL
HANDLING: See Section 8.
The toxicologic data indicate that these materials should be handled with caution. The handling
practices described in Section 8 of this MSDS must be strictly followed.
Product which has been in service at elevated temperature ( > 1800o F ) may undergo partial
conversion to cristobalite, a form of crystalline silica. This reaction occurs at the lining hot face.
As a consequence, this material becomes more friable (brittle); special caution must be taken to
minimize generation of airborne dust. The amount of cristobalite present will depend on the
temperature and length in service.
IARC has recently reviewed the animal, human and other relevant experimental data on silica in
order to critically evaluate and classify the cancer causing potential. Based on its review, IARC
has now classified crystalline silica/cristobalite as a Group 1 carcinogen. Crystalline silica inhaled in
the form of quartz or cristobalite from industrial sources was classified as carcinogenic to humans
on the basis of a relatively large number of epidemiological studies that together provided sufficient
evidence in humans for the carcinogenicity of inhaled crystalline silica under the conditions
specified. Crystalline silica is also listed by the NTP as a substance reasonably anticipated to be a
carcinogen.

7. HANDLING, STORAGE AND DISPOSAL (CON'T)
HANDLING (CON鈥橳): See Section 8.
Therefore, special care should be taken when working with "used" material to minimize the
generation of dust. The OSHA permissible exposure limit (PEL) for cristobalite is 0.05 mg/m3
(resp.). The ACGIH threshold limit value (TLV) for cristobalite is 0.05 mg/m3 (resp.). (ACGIH
1989 - 90). If exposure limits are exceeded or if irritation is experienced, NIOSH approved
respiratory protection should be worn. NIOSH approved respirator for particulates with a TLV of
less than 0.05 mg/m3 is generally acceptable, except that supplied air respirators are required for
high airborne dust concentrations.
STORAGE: Store in a clean, dry area. Keep containers closed.
DISPOSAL: Dispose in accordance with federal, state and local regulations as a solid nonhazardous
waste.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
VENTILATION: General dilution ventilation and/or local exhaust ventilation should be provided,
as necessary, to maintain exposures below PEL's or TLV's. Adequate ventilation
must be provided at elevated temperatures. The base silica material is
noncombustible; however, at temperatures above 250oF, the coating may generate
some light steam and/or smoke for a brief period which may require local ventilation
and/or exhaust.
RESPIRATORY PROTECTION: A properly fitted NIOSH/MHSA approved disposable dust respirator
such as the 3M model 8710 or model 9900 (in high humidity
environments) or equivalent should be used when: high dust levels
are encountered; the level of fibers in the air exceeds the OSHA
permissible exposure limits; or if irritation occurs. Use respiratory
protection in accordance with your company's respiratory protection
program and OSHA regulations under 29 CFR 1910.134.
EYE PROTECTION: Wear safety glasses or chemical goggles to prevent eye contact. Contact lenses
should not be worn unless chemical goggles are also used and care is taken not to
touch the eyes with contaminated body parts or materials. Have eye washing
facilities readily available where eye contact can occur.
PROTECTIVE CLOTHING: Wear loose fitting, long sleeved shirt that covers to the base of the neck,
and long pants. Skin irritation from exposure to silica fibers is known to
occur chiefly at pressure points such as around the neck, wrist and waist.
Wear gloves when handling product.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION (CON'T)
WORK/HYGIENIC PRACTICES: Handle in accordance with good industrial hygiene and safety
practices:
= Avoid unnecessary exposure to dusts and fibers
= Remove fibers from skin after exposure
= Be careful not to rub or scratch irritated areas. Rubbing or scratching may force the fibers into
the skin. The fibers should be washed off. Use of barrier creams can, in some instances, be
helpful.
= Use vacuum equipment to remove fibers and dusts from clothing. COMPRESSED AIR
SHOULD NEVER BE USED. Always wash work clothes separately and wipe out the
washer/sink in order to prevent loose fibers from getting on other clothes.
= Keep the work area clean of any dusts and fibers generated during fabrication. Use vacuum
equipment to clean up dusts and fibers. Avoid sweeping or using compressed air as these
techniques resuspend dusts and fibers into the air.
= Have access to safety showers and eye wash fountains.
= For professional use only. Keep out of children's reach.
