1.2. IDENTIFICATION OF THE DANGER
Rapid evaporation of the liquid can cause freezing. The vapours are heavier than air and can cause suffocation by reducing the oxygen available
for breathing.

In case of unconsciousness, place the person on his side in a stable position and calll a
doctor. Do not administer anything to unconscious persons. In the case of irregular breathing
or respiratory failure, carry out artifical respiration. If the problems persist, call a doctor.
Go into the open air. Put the affected person into the rest position and keep him warm.
Artifical respiration and/or oxygen may be necessary.
Wash with warm water. Immediately remove all contaminated items.
Rinse well with a lot of water, also under the eyelids.
Consult a doctor.
Do not administer adrenalin or similar substances.
Acute toxicity due to inhalation, excessive exposure can damage health as follows:
• Serious breathing problems
• Narcosis
• Irregular cardiac activity
Pressure increase
In the case of fire, wear breathing equipment with independent air intake.
Use extinguishing systems that are compatible with the local situation and the surrounding
environment. Cool the containers/tanks using jets of water.
Do not disperse into the environment
Evaporates
• Ensure sufficient air change and/or suction in the work areas. For saving and
maintenance, dismantling and disposal operations, always use autonamous breathing
equipment. The vapours are heavier than air and can cause suffocation by reducing the
oxygen available for breathing.
• Protect hands using heat-insulated gloves
• Protect the eyes using goggles
• Handle respecting good industrial hygiene practice and suitable safety measures.
Keep the containers hermetically closed in a dry, well-ventillated environment. Keep in original
containers.
There are no materials that must be specifically mentioned.
Can be used after re-conditioning
The de-pressured containers must be returned to the supplier
