Physical hazards

2 3 1 PERSONAL PROTECTION Based on Nat’l Paint & Coating Association HMIS System Chemical not listed. Ratings based on NFPA guidelines Effects of Overexposure Acute Inhalation | Exposure to vapor, mist or liquid can produce burns of the respiratory tract. Severe exposures could result in chemical pneumonia Eyes | Contact can cause severe damage including burns and blindness. The severity of the effects depend on concentration and how soon after exposure the eyes are washed. Skin | Corrosive. Contact may cause burns and tissue destruction. Ingestion | Severe burns and complete tissue perforation of the mucous membranes of mouth, throat, and stomach. (Continued) Chronic No known effects. Note Irritation may follow an initial latency (delay between the time that the exposure occurs and when the sense of irritation starts). The latent period can vary as much as hours for a dilute solution (0.04%) to minutes with more concentrated solutions (25-50%). Prolonged or repeated contact, even to dilute concentrations, can cause a high degree of tissue destruction. Appearance Clear liquid. Routes of Entry Inhalation | Inhalation of caustic vapors or mist may be irritating to the respiratory tract. Eye Contact | Eye contact may cause severe irritation and burns. Skin | Skin contact may cause severe irritation and burns. Ingestion | Corrosive. Severe burns and complete tissue perforation of the mucous membranes of mouth, throat, and stomach.
