Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/
Fire Fighting
FIRE Explosive. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
In case of fire in the surroundings: use appropriate extinguishing media.
Explosion Risk of fire and explosion.
Do NOT expose to friction or shock. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
Combat fire from a sheltered position.
Exposure


 •Inhalation Dizziness. Headache.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •Skin
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •Eyes Redness.
Safety goggles, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •Ingestion Dizziness. Headache.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
Spillage Disposal Storage Packaging & Labelling
Evacuate danger area! Consult an expert! Personal protection: P2 filter respirator for harmful particles. Remove all ignition sources. Cover the spilled material with water. Carefully collect remainder, then remove to safe place. Do NOT wash away into sewer.
Fireproof. Separated from strong oxidants. Store in an area without drain or sewer access.
