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

Wear a self-contained breathing apparatus and chemical protective clothing.In case

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

6.1 Personal precautions (spillage)

Wear personal protection equipment.

6.2 Environmental precautions

Stop leaks if possible. Contain spillage by any means available.

Cover drains. Do not allow to enter into soil/subsoil. Do not empty into drains or the

aquatic environment.

6.3 Methods for cleaning up

Refer to chapter 6.4

6.4 Additional information

Evacuate danger area! Personal protection: complete protective clothing including

self-contained breathing apparatus. Consult an expert! Ventilation. NEVER direct

water jet on liquid.

Handling and storage

7.1 Handling

7.1.1 Advices on safe handling

Protective measures

Wear personal protection equipment. Refer to chapter 8. Do not eat, drink, smoke or

sneeze at the workplace.

Dangerous areas must be delimited and marked with appropriate warning and safety

signs. In the immediate working surroundings there must be: Emergency spray

washing facilities. Fill only into labelled container. Instruction on the hazards and the

protective measures using instruction manual are required with signature.

Working areas must be arranged in such a manner that they can be cleaned at all


7.1.2 Technical measures

Measures to prevent aerosol and dust generation

All work processes must always be designed so that the following is excluded:

Inhalation. Skin contact. Eye contact.

Transfer and handle product only in closed systems.

Measures required to protect the environment

Cover drains. In case of gas being released or leakage into waters, ground or the

drainage system, the appropriate authorities must be informed. Use a water spray jet

to knock down vapours/gases/mists. Do not allow to enter into soil/subsoil. Do not

empty into drains or the aquatic environment.

7.1.3 Specific requirements or handling rules

The floor should be leak tight, jointless and not absorbent.
