TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

 •INHALATION Cough. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
 •SKIN
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
 •EYES
Safety spectacles 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

Rest. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: complete protective clothing including self-contained breathing apparatus.
