Section 3 - Fire and Explosion Data
Flash Point (°F): N.A. (Not Applicable)
Auto Ignition Temperature (°F): N.A.
Extinguishing Media:
Water, Foam, Dry Chemical
Method Used: N.A.
Flammability Limits (%): LEL: N.A. UEL: N.A.
Special Fire-Fighting Instructions: In a sustained fire, self-contained breathing apparatus should be worn.
Unusual Fire and Explosion Hazards: The facing on kraft paper and foil faced products will burn and should
not be left exposed. Special care should be taken when working close to the facing with an open flame. Vinyl
faced products in fire conditions may give off hydrogen chloride, a highly irritating and toxic gas. Evacuate the
building immediately.
Section 4 - Health Hazard Data
Primary Routes of Exposure: Inhalation and skin contact.
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 product itching and temporary mechanical
irritation.
Eye Contact: Eye contact with dusts and fibers 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 other known health effects associated with chronic
exposure to this product.

Hazardous Ingredients:

Fiberglass Wool No Yes No No
IARC: The International Agency for Research on Cancer (IARC) in June, 1987, classified fiberglass wool as
a possible cancer causing agent to humans (Group 2B). This classification was based on a combined evalua-
tion of published human and animal studies. The human data included large scale mortality studies of U.S.
and European fiberglass wool factory workers. IARC concluded that the human studies did not provide suffi-
cient evidence that fiberglass wool caused cancer in human. The classification of fiberglass wool as a possi-
ble carcinogen to humans was substantially based on experimental animal studies in which they were
exposed to wool glass fibers through non-natural routes, such as injection or implantation. IARC regards it as
prudent to treat a material for which there is sufficient evidence of carcinogenicity to animals as if it is a possi-
ble carcinogen in humans.
Additional Information: Animal inhalation experiments in which laboratory animals were exposed to large
quantities of glass fiber have not resulted in a positive association between glass fibers and lung cancer. A
small study of Canadian glass wool workers reported a statistically significant increase in lung cancer mortali-
ty.
Large scale studies published in 1987 which examined the mortality rates of U.S. and European fiber-
glass wool factory workers found no statistically significant difference in lung cancer rates between those
workers and the populations in their local or regional communities. A 1990 update of the U.S. cohort reported
a small statistically significant excess for respiratory cancer in workers when compared with populations in
their local communities. While the overall mortality rates in these mortality studies were slightly raised and did
increase with time since the first exposure, the increases were not related to duration of exposure or to an
estimated time weighted measure of exposure. An expanded study is investigating other possible factors.
