Emergency Response Information
OXIDISING LIQUEFIED REFRIGERATED GAS

1. Characteristics
  • Hazardous to skin, eyes and air passages.
  • Liquid has extremely low temperature.
  • The gas may suffocate without warning.
  • Intensifies fire.
  • Not flammable.

2. Hazards
  • Heating of container(s) will cause pressure rise with risk of bursting and immediate release of expanding vapour cloud creating a pressure wave (risk of BLEVE).
  • Contact with liquid will make many materials brittle, including personal protective equipment.
  • Contact with liquid will cause frostbite and severe damage to eyes.
  • Contact with combustible substances may lead to fire or explosion.
  • The gas may be invisible and may enter sewers, basements or confined spaces.
  • Increases fire risk of combustible material particularly clothing.

3. Personal Protection
  • Chemical protection suit.
  • Self contained breathing apparatus.
  • Insulating undergarments and thick textile or leather gloves.

4. Intervention Actions
  4.1 General
  • No smoking, eliminate ignition sources.
  • Keep upwind. Put on protective equipment before entering danger area.
  • Minimise number of personnel in risk area.
  • Avoid contact with combustible substances (e.g. fuels).

  4.2 Spillage
  • Stop leaks if possible.
  • Knock down or disperse gas cloud with water spray.
  • Do not use plugs made from organic material like wood, to stop leaks.
  • If substance has entered a water course or sewer, inform the responsible authority.
  • In the absence of specialist advice, allow spill to evaporate. If there is no risk to people, assist with water spray.

  4.3 Fire (involving the substance)
  • Keep container(s) cool with water.
  • Do not direct water at source of leak or safety devices.
  • Cut off gas supply if safe to do so.
  • Use water spray to knock down fire fumes if possible.
  • Avoid unnecessary run-off of extinguishing media which may cause pollution.

5. First Aid
  • If substance has got into eyes, wash out with water for at least 15 minutes and seek immediate medical attention.
  • Remove contaminated clothing immediately and drench affected skin with plenty of water.
  • Persons who have been in contact with the substance or have inhaled fumes should get immediate medical attention. Pass on all available product information.
  • Thaw frosted parts carefully with cold water.

6. Essential Precautions For Product Recovery
  • Do not use standard recovery equipment. Seek specialist advice immediately.

7. Precautions After Intervention
  7.1 Undressing
  • No special precautions.

  7.2 Equipment Clean Up
  • Seek specialist advice as soon as practicable and before re-use.
