Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/
Fire Fighting
FIRE Highly flammable. Heating will cause rise in pressure with risk of bursting.
NO open flames, NO sparks, and NO smoking.
Carbon dioxide. Dry powder.
Explosion Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
Exposure


 •Inhalation Cough. Sore throat.
Ventilation.
Fresh air, rest.
 •Skin
Protective gloves.
Rinse skin with plenty of water or shower.
 •Eyes Redness.
Safety spectacles.
Rinse with plenty of water (remove contact lenses if easily possible).
 •Ingestion
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Seek medical attention if you feel unwell
Spillage Disposal Storage Packaging & Labelling
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Remove all ignition sources. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer.
Fireproof. Separated from oxidants. Well closed. Ventilation along the floor. Store in an area without drain or sewer access.
