First-Aid Measures
- Eyes
- Rinse with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention immediately.
- Skin
- Immediately flush with plenty of water for at least 15 minutes while removing contaminated clothing. Wash with soap. Get medical attention immediately.
- Inhalation
- Move person to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention immediately.
- Ingestion
- Do Not Induce Vomiting! Never give anything by mouth to an unconscious person. If conscious, wash out mouth with water. Get medical attention immediately.
- Most Important Symptoms and Effects
- Causes burns to the skin, eyes and mucous membranes; eye contact may cause permanent damage including blindness; ingestion burns the mouth, throat and stomach.
- Immediate Medical Attention and Special Treatment
- Immediate medical attention is required after eye or skin contact or ingestion; tissue damage may continue after exposure ends.
Fire-Fighting Measures
- Suitable Extinguishing Media
- Dry chemical, CO2, water spray. Use water spray to cool containers.
- Unsuitable Extinguishing Media
- Do not use a solid water stream as it may scatter and spread fire.
- Specific Hazards Arising from the Chemical
- Fire may release corrosive and toxic gases. Containers may rupture when heated.
- Protective Equipment
- Wear self-contained breathing apparatus and full protective clothing.
- Hazardous Combustion Products
- Phosphorus oxides at very high temperature; flammable hydrogen gas from contact with metals.
Accidental Release Measures
- Personal Precautions
- Use PPE as described in Section 8. Ensure adequate ventilation. Evacuate personnel to safe areas.
- Hazard-Specific Precautions
- Do not touch spilled material without protective equipment. Neutralize residue only with a method suitable for the material, then collect.
- Environmental Precautions
- Prevent leakage or spillage from entering drains, sewers, or waterways.
- Containment & Cleanup
- Absorb with inert material. Collect in appropriate waste container. Dispose per applicable regulations.
Handling and Storage
- Safe Handling
- Use with adequate ventilation. Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling. Keep container closed when not in use.
- Safe Storage
- Store in a cool, dry, well-ventilated area. Use corrosion-resistant containers. Keep away from incompatible materials (see Section 10). Keep containers tightly closed.
- Specific Storage Precautions
- Keep closed in polyethylene or other acid-resistant containers, not mild steel, away from bases, bleach and metals.
Exposure Controls / Personal Protection
Occupational Exposure Limits
| Limit | Value |
|---|---|
| OSHA PEL | 1 mg/m³ TWA |
| NIOSH REL | 1 mg/m³ TWA / 3 mg/m³ STEL |
| IDLH | 1000 mg/m³ |
- Engineering Controls
- Use adequate ventilation. Provide eyewash stations and quick-drench showers accessible to areas of use.
- Eye/Face Protection
- Wear chemical safety goggles or face shield.
- Skin Protection
- Wear chemical-resistant gloves and protective clothing.
- Respiratory Protection
- Where mist, spray or dust is generated (e.g., spraying, atomization, pressure washing), use a NIOSH-approved half-face air-purifying respirator with combination acid gas / P100 cartridges. Ensure local exhaust ventilation.
Exposure limits sourced from NIOSH Pocket Guide, OSHA 29 CFR 1910.1000 and ACGIH TLVs.
