Inhalation: Move individual to fresh air, keep calm and comfortable, seek medical attention if breathing becomes difficult.
Skin Contact: Wash area thoroughly with water and mild soap, remove any contaminated clothing.
Eye Contact: Rinse eyes with plenty of clean water for several minutes, keep eyes open, and seek medical advice if irritation lingers.
Ingestion: Rinse mouth with water, do not induce vomiting, and consult a doctor if symptoms develop.
Suitable Extinguishing Media: Use water spray, dry chemical powder, or carbon dioxide.
Hazards from Combustion: Burning pimelic acid can give off carbon monoxide, carbon dioxide, and minor amounts of irritating fumes.
Protective Actions: Wear a self-contained breathing apparatus and full protective gear to avoid inhaling hazardous vapors.
Personal Precautions: Put on gloves, safety glasses, and a dust mask if working near spills, avoid breathing in dust, wash thoroughly after handling.
Environmental Precautions: Do not let product enter drains, gather spilled material to prevent it from spreading, keep out of waterways.
Cleanup Methods: Sweep or shovel up the material, place in a clearly labeled container for waste disposal, rinse area with plenty of water after cleanup.
Precautions for Safe Handling: Avoid creating or inhaling dust especially in poorly ventilated areas, wear gloves and goggles, never eat or drink near material, wash hands after handling.
