May cause thermal burns. Primary Routes of Exposure: Eyes, skin, and inhalation of combustion products. Eye Contact: Direct contact of liquid with the eyes will cause thermal burns and possible blindness. Skin Contact: Liquid bursts in to flame in air, causing thermal burns to skin. Fume causes burns to the nose, mucous membranes and respiratory tract causing metallic taste, dry throat, Inhalation: and chills. Ingestion: Ingestion is an unlikely mode of entry as the material is pyrophoric. Acute Health Affects: Causes burns to skin, eyes and respiratory tract. Inhalation may cause chills and nausea. No serious long-term chronic effects associated with zinc compounds. Prolonged inhalation may cause Chronic Health Affects: laryngitis. Prolonged ingestion may cause constipation. NTP: No IARC: No OSHA: No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with a large volume of water applied rapidly.
