SECTION 2: Hazards identification

Emergency Overview: OSHA regulations do not require respiratory protection as long as the exposure to fiber glass wool does not exceed 1 fiber/cubic centimeter (f/cc) TWA (8 hour time weighted average). Fiber Glass wool exposure in the home, commercial buildings, and manufacturing facilities are generally found to be less than 1 f/cc. Installers of blowing wool in an enclosed space such as an attic may experience respirable fiber exposures higher than 1 f/cc. Installers and fabricators should be aware of their exposure levels and take appropriate actions if needed per recommended work practices. Knauf Insulation STRONGLY recommends following all safe work practices while working with and/or installing fiber glass wool products. Protection: E

Principle Routes of Exposure

Via respirable fibers to the lungs and respiratory system and airborne fibers to the skin and eyes. Primary Target Organs: Lungs, respiratory system, skin and eyes. Trade Name: Knauf Insulation Unbonded Blowing Wool MSDS Number: 1005

Potential health effects

Acute: Mechanical irritation of the skin, eyes and upper respiratory system. Fiber glass wool is classified as a nuisance dust by OSHA. Chronic: Results from the most recent cohort and nested case-control epidemiological studies of U.S. workers exposed to glass wool have not provided evidence of an association between exposure to fibers and risk for respiratory cancer or mesothelioma. Skin Contact: There are confirmed reports of contact dermatitis. Eye Contact: A mechanical irritant which can cause moderate to severe eye irritation. Ingestion: Non-hazardous when ingested. Potentially a mild Irritant to the GI tract if excessive quantity is ingested.

Medical Conditions Generally Aggravated by Exposure

Pre-existing chronic upper respiratory and lung diseases such as, but not limited to, bronchitis, emphysema and asthma. Skin disease such as dermatitis Biosolubility: All Knauf Insulation products covered by this SDS are independently certified by EUCEB to be manufactured using biosoluble glass formulations and thus exempt from labeling under NTP or California Prop 65 requirements.
