Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Extinguishing Media: Do not use straight streams of water on burning material
Special Hazards: Toxic fumes of arsenic, sodium oxides, and possible explosive dust-air mixtures
Firefighter Protection: Wear full protective clothing and self-contained breathing apparatus (SCBA); avoid inhaling hazardous decomposition products
Specific Precautions: Evacuate non-essential personnel; cool exposed containers with water spray; prevent runoff from entering waterways
Personal Precautions: Use appropriate personal protective equipment such as gloves, goggles, chemical-resistant suit, and respiratory protection
Environmental Precautions: Prevent spillage from reaching drains, sewers, surface and groundwater
Spill Clean-Up Methods: Avoid raising dust; sweep or shovel up and place in suitable closed containers for disposal; decontaminate area with water and detergent
Notification: Inform local authorities if significant environmental contamination occurs
Safe Handling Guidelines: Always handle in well-ventilated area; use protective equipment; avoid spills, dusts, and direct contact
Storage Recommendations: Store in tightly closed, properly labeled containers in cool, dry, ventilated storage; isolate from incompatible materials such as acids, oxidizers, and reducing agents
Hygiene Requirements: Do not eat, drink, or smoke in areas where sodium arsenate is handled; wash hands and face thoroughly before breaks or eating
