Advice for Firefighters: Approach from upwind, avoid runoff into waterways and drains, decontaminate equipment after use
Personal Precautions: Wear chemical-resistant gloves, safety goggles, respirators in poorly ventilated areas, avoid dust inhalation, keep away from skin
Environmental Precautions: Prevent release to soil, drains, and natural waterways, contain spillage with inert materials such as sand or earth
Cleanup Methods: Collect solids with non-combustible absorbent, transfer to labeled waste container for proper disposal, ventilate area and wash after cleanup
Small Spills: Mop up dry material, wipe surfaces thoroughly, use plastic tools, avoid generating dust
Large Spills: Evacuate area, shut off all ignition sources, build dam with soil or sand to prevent spread, alert appropriate environmental authorities
Handling: Handle only with adequate local exhaust ventilation, use personal protective equipment at all points of contact, do not breathe dust or fumes, avoid direct skin and eye exposure, maintain good hygiene and clean work area regularly
Storage: Store in tightly sealed original containers, preferably in a cool, dry, and well-ventilated place, keep away from direct sunlight, oxidizers, strong acids and bases, separate from food and potable water sources, lock storage for authorized personnel access only
Incompatibilities: Avoid contact with strong reducing agents, bases, and flammable materials
Other Precautions: Keep emergency eyewash and shower stations accessible, post clear hazard warning signs in storage and usage areas
Occupational Exposure Limits: No specific occupational exposure limits set by OSHA, NIOSH, or ACGIH, use engineering controls to minimize airborne levels
Engineering Controls: Use local exhaust or fume hoods, install chemical-resistant work surfaces
Respiratory Protection: Use NIOSH-approved respirators when risk of inhalation exists, choose filters rated for organic vapors and particles
Skin Protection: Wear nitrile or neoprene gloves, long-sleeved impervious clothing, closed shoes
