Mecical Conditions Aggravated by Exposure:

Inhalation

Rash, itching, conjunctivitis, coughing, sneezing

None known

Health Hazards:

(Acute): Exposure to glass fiber sometimes causes irritation of the skin and, less frequently, irritation of the eyes, nose, or throat.

(Chronic): A number of epidemiology studies, done over many years, of workers employed up to 40 years in the manufacture of fiber glass have shown no evidence of increases in either malignant or non-malignant respiratory disease attributable to exposure to fiber glass. However, recent studies have shown slight increases in lung cancer among workers

cont. Section 5 - Health Hazard Data

employed in the manufacture of glass wool and mineral wool insulation products. Those same studies showed no evidence of a similar effect among continuous filament fiber glass workers. This product is a continuous fiber glass product. Animal inhalation studies for fiber glass have not shown evidence of either a carcinogenic fibrogenic response. Studies using artificial implantation or injection of glass fibers into animals have resulted in cancer. However, since there are no natural mechanisms which would mimic such artificial exposures, those studies are not thought to be relevant to human exposure.

Carcinogenicity Status: Continuous filament fiber glass has been designated by IARC as a Group 3, "not classifiable as to human carinogenicity". This means that evidence is insufficient to link that fiber to cancer.

Emergency and First Aid Procedures:

Eye Contact: Flush eyes with clear water for at least 15 minutes - seek medical attention.

Skin Contact: Rinse contacted areas with room temperature to cool water, then wash gently with mild soap. If fiber glass

Becomes embedded, seek medical attention.

Steps to be Taken in Case Material is released or Spilled: No special precautions.

Waste Disposal Method: Dispose of as solid waste in accordance with local, state, and federal regulations. Not considered a hazardous waste under federal "RCRA" regulations.

Section 8 - Special Protection Information

Protective Gloves

Eye Protection:

May reduce skin irritation in some operations

Safety glasses with side shields.

Respiratory Protection: None normally required. If airborne fiber glass concentrations exceed permissible exposure levels, respiratory protection for nuisance dusts in accordance with OSHA 1910.134 should be provided.

Ventilation: Use local exhaust ventilation if necessary to maintain airborne levels to below established limits.

Other protective Equipment: Use of long sleeved shirts, buttoned to fit loosely at the neck and wrist, long pants, an good personal hygiene will maximize comfort.
