TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. NO open flames. NO contact with acid(s), base(s). Powder, foam, carbon dioxide
EXPLOSION Above 76°C explosive vapour/air mixtures may be formed. Above 76°C use a closed system, ventilation. In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
 
EXPOSURE   AVOID ALL CONTACT!  
Inhalation Dizziness. Drowsiness. Unconsciousness. Vomiting. Local exhaust or breathing protection. Fresh air, rest.
Skin Redness. Pain. Protective clothing. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain. 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 Abdominal pain. (Further see Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Refer for medical attention.
