Potential Health Effects Eye: Causes eye burns. Skin: Causes skin burns. Ingestion: Causes gastrointestinal tract burns. The toxicological properties of this substance have not been fully investigated. Inhalation: Causes chemical burns to the respiratory tract. The toxicological properties of this substance have not been fully investigated. Chronic: Chronic exposure may cause effects similar to those of acute exposure. Section 4 - FIRST AID MEASURES Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid immediately. Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse. Ingestion: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person. Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Treat symptomatically and supportively. Section 5 - FIRE FIGHTING MEASURES General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear.
