Ingestion: Rinse mouth with water; give water to drink; call a physician in case of discomfort.
Most Important Symptoms: Dust may provoke itching or redness; keep under surveillance for respiratory symptoms.
Healthcare Attention and Special Treatment: Provide symptomatic support, monitor basic vital signs, and consult poison information if large amounts are involved.
Safety Note: Emergency showers and eye-wash stations should be close to work areas.
Suitable Extinguishing Media: Use water spray, foam, carbon dioxide, or dry chemical.
Special Hazards: Combustion can yield carbon oxides and nitrogen oxides in small quantities.
Protective Equipment: Firefighters need full protective gear, including self-contained breathing apparatus, to guard against inhalation of combustion byproducts.
Unusual Fire or Explosion Hazards: Dust formation in air may build up static or minimally increase risk, but not classified as a high risk for explosion.
Advice for Firefighters: Approach fires upwind; avoid contamination from extinguishing water; decontaminate equipment after use.
Personal Precautions: Wear gloves, goggles, a dust mask or respirator; prevent exposure to skin, eyes, or from inhalation.
Environmental Precautions: Keep powder out of drains, water sources and soil; collect spilled material in waste containers.
