This chemical is classified as causing severe skin burns and eye damage (H314), harmful if swallowed (H302), and irritating to the respiratory tract (H335). Pentafluorophenol CAS 771-61-9 is incompatible with strong bases, acids and oxidants; decomposition may release toxic hydrogen fluoride fumes. The solid form can cause skin and eye corrosion upon contact, and inhalation of dust or vapors may lead to respiratory irritation and damage. It is not a flammable solid, but heating to high temperatures can produce hazardous decomposition products.
