ACFoam-II Roof Insulation
Product Synonyms
Rigid Foam Insulation
1.2.1 Relevant identified uses
Rigid foam insulation panels for installation as delivered over roof decks. ACFoam-II consists of a flat or tapered closed-cell polyisocyanurate foam core bonded on both sides to a dark gray non-asphaltic, glass fiber reinforced organic felt facer. The thickness of the foam ranges from 0.5 to 4.5 inches. Intended to be covered by hot asphalt or coal tar BUR, modified bitumen, and single ply membrane system roof coverings

Potential health effects
Primary Means of Exposure: Inhalation of particulates Secondary Means of Exposure: Eye and skin contact with particulates and inhalation of vapors INHALATION HEALTH HAZARDS: For polyiso foam (generated dust and residual vapor) and for organics in facers (generated dusts) Acute: Dust may cause transient mechanical irritation of the upper respiratory tract. Workplace exposures to residual pentane vapors from this product are expected to be below levels of any health risk. Overexposure to high concentrations of pentane can cause narcotic effects. Signs and symptoms of overexposure to pentane include headache, nausea, dizziness, difficulty walking, or sleepiness. Studies have shown that short-term (10-minute) exposures to pentane concentrations as high as 5,000 ppm (11,750 mg/m3) produced no symptoms. Workplace exposure limits for pentane and other organic components are provided in table below. Chronic: There is no evidence that dusts generated from these products cause disease in humans. Facer dusts containing carbon black pigment are not analogous to the raw carbon black powders for which human carcinogenicity is suspected. No chronic effects are known for exposures to pentane vapor. For continuous filament glass fibers in facers (generated dust) Acute: Airborne fragments of glass fibers may cause mechanical irritation of the upper respiratory tract, particularly mouth, nose and throat; glass dust may cause transient irritation of the upper respiratory tract. Workplace exposure limits are provided in table below. Chronic: No chronic health effects are known to be associated with exposure to glass fibers. Results from epidemiological studies have not shown any increase in respiratory disease or cancer. The International Agency for Research on Cancer has classified continuous filament fiberglass “Not Classifiable as to Carcinogenicity to Humans” (Group 3). EYE CONTACT HEALTH HAZARDS: Acute: Mechanical irritation, redness, tearing, and blurred vision can occur if dusts generated from these products come into contact with eyes. Chronic: None known. SKIN CONTACT HEALTH HAZARDS: Acute: Direct contact with rough-cut foam or felt facers can cause mechanical abrasion cuts or puncture to fingers, hands or exposed skin. Chronic: None known. SIGNS AND SYMPTOMS OF EXPOSURE: Irritation of the upper respiratory tract, eyes, and/or skin.
