TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible.
NO open flames, NO sparks, and NO smoking.
Foam, carbon dioxide, powder .
EXPLOSION Above 98°C explosive vapour/air mixtures may be formed.
Above 98°C use a closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE


 •INHALATION Dizziness. Headache. Nausea.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
 •SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
 •EYES Severe deep burns. 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 Nausea. Vomiting. Dizziness. Drowsiness. Headache. Weakness.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: filter respirator for organic gases and vapours.
Separated from strong oxidants, strong bases.

ICSC: 0035 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.
