Emergency Response Information
TOXIC CORROSIVE GAS, LIQUEFIED OR DISSOLVED UNDER PRESSURE

1. Characteristics
  • Corrosive, causing damage to skin, eyes and air passages.
  • Toxic by inhalation or skin absorption.
  • Not flammable.
  • The gas is absorbed or readily dispersed by water fog/spray.

2. Hazards
  • May react in a fire to produce toxic or irritant gases or fumes.
  • Heating of container(s) will cause pressure rise with risk of bursting and immediate release of expanding toxic and corrosive vapour cloud creating a pressure wave (risk of BLEVE).
  • Contact with liquid will cause frostbite and severe damage to eyes.
  • May attack metals and produce hydrogen gas which may form explosive mixture with air.
  • The gas may be invisible and may enter sewers, basements or confined spaces.

3. Personal Protection
  • Gas tight suit.
  • Insulating undergarments and thick textile or leather gloves.

4. Intervention Actions
  4.1 General
  • PUBLIC SAFETY HAZARD - Warn people nearby to stay indoors with doors and windows closed. Stop any ventilation. Consider evacuation of people in immediate danger.
  • Keep upwind. Put on protective equipment before entering danger area.
  • Minimise number of personnel in risk area.
  • Warn people to leave and not to re-enter basements, sewers or other confined spaces.

  4.2 Spillage
  • Stop leaks if possible.
  • Knock down or disperse gas cloud with water spray.
  • If substance has entered a water course or sewer, inform the responsible authority.
  • Ventilate sewers and basements where there is no risk to personnel or public.
  • In the absence of specialist advice, drench spillage with water spray to assist evaporation and absorb gas but avoid unnecessary run off which will cause pollution.

  4.3 Fire (involving the substance)
  • Keep container(s) cool with water.
  • Work from protected position to reduce risk to personnel. Use unmanned monitors or lances.
  • 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.
  • Mouth to mouth resuscitation should be avoided. Use alternative methods, preferably with oxygen or compressed air driven apparatus.
  • 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
  • Drench contaminated suit and breathing apparatus with water before removing facemask and suit.
  • Use chemical protection suit and self contained breathing apparatus while undressing contaminated co-workers or handling contaminated equipment.

  7.2 Equipment Clean Up
  • Seek specialist advice before leaving incident.
