Inhalation: Move to fresh air immediately. Seek medical attention. If breathing becomes difficult, administer oxygen. Apply artificial respiration if not breathing.
Skin Contact: Remove contaminated clothing right away. Rinse skin with plenty of water for at least 15 minutes. Seek prompt medical advice.
Eye Contact: Rinse eyes with water, holding eyelids apart, for at least 15 minutes. Remove contact lenses if present and continue rinsing. Obtain medical attention immediately.
Ingestion: Do not induce vomiting. Rinse mouth with water if conscious. Seek urgent medical help.
Note to Physicians: Symptoms may be delayed. Treat symptomatically and monitor for signs of arsenic poisoning.
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or foam; avoid water jets
Specific Hazards from the Chemical: Emits toxic fumes of arsenic oxides and zinc oxides when heated to decomposition
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear
Special Firefighting Procedures: Isolate hazard area. Cool containers with water spray if exposed to fire, but avoid direct water on material. Prevent runoff from entering waterways.
Explosion Data: Product is not explosive but dust may cause static discharges
Unusual Fire Hazards: Toxic, irritating gases possible; ensure proper ventilation
Personal Precautions: Wear appropriate personal protective equipment such as gloves, goggles, and respiratory protection. Notify emergency personnel. Wash hands thoroughly after handling.
Environmental Precautions: Prevent spillage from entering drains, watercourses, and soil. Inform relevant authorities if large releases occur.
Method for Containment: Cover drains. Dampen spilled powder with water to prevent dust formation. Shovel or sweep up material without generating dust and place in a suitable container for disposal.
Cleanup Procedures: Ventilate the area. Use HEPA filter vacuums or wet methods to clean up dust. Wash tools and contaminated surfaces with soap and water.
Safe Handling: Handle in well-ventilated areas. Use local exhaust. Avoid contact with eyes, skin, and clothing. Minimize dust generation and accumulation. Never eat, drink, or smoke near this material. Wash hands and face after work.
Storage Conditions: Keep containers tightly closed in a dry, cool, well-ventilated area. Store away from incompatible materials like strong acids, reducing agents, and foodstuffs.
Storage Incompatibilities: Acids, combustibles, and organic materials
Packaging Materials: Use corrosion-resistant, sealed containers clearly labeled with hazard information.
Exposure Limits: OSHA PEL for arsenic, inorganic: 0.01 mg/m3 as As; ACGIH TLV for arsenic: 0.01 mg/m3 (as As); zinc compounds not established
Engineering Controls: Use local exhaust, enclosed processes, and mechanical ventilation
Respiratory Protection: Use NIOSH-approved respirators if exposure exceeds regulatory limitations
Skin Protection: Wear chemical-resistant gloves (nitrile, neoprene), long sleeves, and closed shoes
Eye/Face Protection: Wear chemical safety goggles or face shield
Hygiene Measures: Wash before eating, drinking, or smoking. Remove and launder contaminated clothing before reuse.
