  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Gas/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).  Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray, alcohol-resistant foam, dry powder, carbon dioxide.  In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Nausea.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves.  ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. 
Eyes   Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Ventilation. Remove all ignition sources. Remove vapour with fine water spray. Personal protection: self-contained breathing apparatus.
