Section 8 - Exposure Controls / Personal Protection
The Occupational Safety and Health Administration (OSHA) has not adopted specific occupational exposure standards for
fiber glass. Fiber glass is treated as a nuisance dust and is regulated by OSHA as a particulate not otherwise regulated (total
dust) shown in CFR 1910.1000 Table Z-3.
Respirable fraction 5 mg/m3
Total dust 15 mg/m3
JM has adopted the fiber glass industry voluntary Product Stewardship Program (PSP), formerly the NAIMA-OSHA Health and
Safety Partnership Program (HSPP). Under the PSP, JM recommends that exposures be limited to the voluntary concentration
of 1 f/cc TWA for fibers longer than 5 microns with a diameter less than 3 microns. This will help minimize potential irritation
effects. The PSP also includes the PPE recommendations described below.
Asphalt (8052-42-4)
ACGIH: 0.5 mg/m3 TWA (fume, inhalable fraction, as benzene soluble aerosol)
Titanium dioxide (Ingredient of GlasKap® CR only) (13463-67-7)
ACGIH: 10 mg/m3 TWA
OSHA: 15 mg/m3 TWA (total dust)
Calcium carbonate (1317-65-3)
OSHA: 15 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction)
Crystalline silica (sand) (adhered to product and is >99.9% too large to become airborne or to be respirable) (14808-
60-7)
ACGIH: 0.025 mg/m3 TWA (respirable fraction)
Aluminum foil (DynaClad® has an aluminum foil surface) (7429-90-5)
ACGIH: 10 mg/m3 TWA (metal dust)
OSHA: 15 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction)
PERSONAL PROTECTIVE EQUIPMENT
Personal Protective Equipment: Eyes/Face
Safety glasses with side shields or chemical goggles are recommended.
Personal Protective Equipment: Skin
Leather or cotton gloves should be worn to protect against mechanical abrasion.
Personal Protective Equipment: Respiratory
None required
Personal Protective Equipment: General
Protective equipment should be provided as necessary to prevent irritation of the throat, eyes, and skin, and to keep

Chronic Toxicity
Asphalt (asphalt CAS # 8052-42-4 and oxidized asphalt 64742-93-4; bitumens): In 1985/87, IARC (International Agency for
Research on Cancer) concluded the following: (a) Bitumens are not classifiable as to their carcinogenicity to humans (Group
3). (b) Extracts of steam- and air-refined bitumens are possibly carcinogenic to humans (Group 2B). IARC found that evidence
for carcinogenicity from animal studies was: inadequate for undiluted air-refined bitumens; limited for steam-refined and
cracking-residue bitumens; sufficient for extracts of steam-refined and air-refined bitumen. IARC found that human evidence
for carcinogenicity of asphalt fumes was inadequate. Studies of roofers indicated an excess of cancers; however, IARC
concluded that, since roofers may be exposed also to coal-tar pitches and other materials, "the excess cancer risk cannot be
attributed specifically to bitumens." In 1994, a published review of 20 epidemiology studies of asphalt workers and roofers
agreed with IARC, that current human evidence is inadequate for the carcinogenicity of asphalt fumes in humans. Trace
amounts of polynuclear aromatic hydrocarbons (PAHs) may be present in some asphalts and can be released upon excessive
heating, which results in thermal cracking of the asphalt compounds. Some of these PAHs have been identified as having the
potential to induce carcinogenic and reproductive health effects.
Continuous Filament Glass Fiber: No chronic health effects are known to be associated with exposure to continuous filament
fiber glass. Results from epidemiologic studies have not shown any increases in respiratory disease or cancer. The
International Agency for Research on Cancer (IARC) has classified continuous filament fiber glass as a Group 3 substance,
not classifiable as to its carcinogenicity to humans. Because of the large diameter of continuous filament fibers, these products
are not considered respirable.
Crystalline silica is considered a hazard by inhalation. The International Agency for Research on Cancer (IARC) has classified
crystalline silica as a Group 1 substance, carcinogenic to humans. This classification is based on the findings of laboratory
animal studies (inhalation and implantation) and epidemiology studies that were considered sufficient for carcinogenicity.
Several studies have been conducted to determine the risk of cancer to workers exposed to dusts which contain crystalline
silica. However, these studies did not consider other factors or elements that workers may be exposed to. Therefore, the
causes of the excess deaths due to cancer could not be precisely determined. Further studies are being conducted to
determine the risk of cancer when working with crystalline silica products. Excessive exposure to crystalline silica can cause
silicosis, a non-cancerous lung disease.
