Fire-fighting measures

5.1 Suitable extinguishing media
Co-ordinate fire-fighting measures to the fire surroundings.
5.2 Extinguishing media which must not be used for safety reasons
5.3 Special exposure hazards arising from the substance or preparation itself,
combustion products, resulting gases
In case of fire may be liberated:
Sulphur dioxide (SO2). Sulphur trioxide.
5.4 Special protective equipment for fire-fighters

5.5 Additional information
Intervention Actions-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. Keep upwind. Put on protective
equipment before entering danger area.
Intervention Actions-Fire (involving the substance)
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. 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.
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

Accidental release measures
