Vapors from Pyralux LG

Potential health effects

As a part of the hazard assessment process, DuPont has conducted industrial hygiene studies to monitor the potential exposure to the off-gases from this product during normal use. Conclusions from the results of these studies indicate that exposure levels during press lamination using adequate ventilation were well below regulated limits (e.g. an order of magnitude below the exposure limit). Tests run for nuisance dust levels at a drilling/routing station with vacuum exhaust also indicated exposure levels well below regulated limits. As a result of this test data, DuPont believes the potential exposure to the vapors and dusts of this product is minimal. Equipment used for lamination and curing must be adequately exhausted.

POTENTIAL HUMAN HEALTH EFFECTS OF OVEREXPOSURE: Inhalation may cause irritation of the upper respiratory passages, with sneezing, coughing and discomfort; or temporary lung irritation effects with cough, discomfort, Continued) difficulty breathing, or shortness of breath. Inhalation, ingestion or skin contact may cause temporary mild depression of the central nervous system with dizziness, confusion, incoordination or drowsiness followed by an asymptomatic period usually ranging from 12 to 24 hours. There are reports that suggest headache, hearing loss and vertigo (dizziness) in workers exposed to less than 110 ppm of 1-Butanol. Skin contact may cause redness of the skin and dermatitis with itching or rash. Evidence from animal testing on some vapor components suggests that skin permeation can occur in amounts capable of producing the effects of systemic toxicity. Eye contact with high concentrations of vapors may cause eye irritation with discomfort, tearing or blurring of vision. Individuals with pre-existing diseases of the central nervous system, liver or kidneys may have increased susceptibility to the toxicity of excessive exposures. Some compounds have been infrequently associated with skin sensitization in humans. Carcinogenicity Information None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC NTP
