Suitable Extinguishing Media: Dry chemical, carbon dioxide, water spray, alcohol-resistant foam
Unsuitable Extinguishing Media: Strong water jets
Specific Hazards: Releases toxic iron and nitrogen oxide fumes when burned
Protective Equipment: Firefighters should wear full protective clothing including self-contained breathing apparatus
Special Procedures: Move containers from fire area if safe to do so. Use water to keep fire-exposed containers cool. Avoid runoff and spillage
Personal Precautions: Use personal protective equipment like gloves, goggles, and dust mask. Ensure adequate ventilation.
Environmental Precautions: Prevent further leakage or spillage if safe—do not let product enter drains or surface water. Contain material to avoid environmental impact.
Cleanup Methods: Sweep up and collect spill, avoiding dust formation. Place in a suitable closed container for disposal according to local regulations. Wash spill site thoroughly after material pickup is complete.
Precautions for Safe Handling: Handle in a well-ventilated area. Avoid inhalation and direct contact with skin, eyes, and clothing. Use protective equipment around open containers or during transfer.
Safe Storage Conditions: Store in tightly closed containers in a cool, dry, well-ventilated place. Keep away from incompatible materials such as strong acids or strong bases. Protect from moisture and direct sunlight. Store away from food and feedstuffs.
Occupational Exposure Limits: No specific limits for ammonium ferric citrate. Maintain exposure to dusts below nuisance dust values—use local workplace regulations as primary reference.
Engineering Controls: Employ local exhaust or general ventilation if handling large quantities or if dust forms.
Personal Protection:
- Respiratory: NIOSH approved mask for dust/particulates
- Eyes: Chemical splash goggles
- Skin: Impervious gloves and lab coat or apron
- Hygiene Measures: Wash hands thoroughly after handling. Remove and wash contaminated clothing before reuse.
