  • Risk of violent reaction when heated or burning.

2. Hazards
  • Heating of container(s) will cause pressure rise with risk of bursting and subsequent explosion.
  • Heating of container(s) will cause pressure rise with risk of bursting and immediate release of the gas which may ignite.
  • May form explosive mixture with air.
  • Gives off toxic and irritant fumes when heated or burning.
  • The vapour may be invisible and is heavier than air. It spreads along the ground and may enter sewers and basements.

3. Personal Protection
  • Chemical protection suit.
  • Self contained breathing apparatus.
  • Consider wearing standard fire fighting clothing underneath the suit.

4. Intervention Actions
  4.1 General
  • No smoking, eliminate ignition sources.
  • Work from protected position to reduce risk to personnel. Use unmanned monitors or lances.
  • Keep upwind. Put on protective equipment before entering danger area.
  • Minimise number of personnel in risk area.

  4.2 Spillage
  • Stop leaks if possible.
  • Contain spillage by any means available.
