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.
1.3. FIRST-AID MEASURES
General information 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.
Inhalation 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.
Contact with the skin
Wash with warm water. Immediately remove all contaminated items.
Contact with the eyes Rinse well with a lot of water, also under the eyelids.
Consult a doctor.
Notes for the doctor
Do not administer adrenalin or similar substances.
Toxological information Acute toxicity due to inhalation, excessive exposure can damage health as follows:
• Serious breathing problems
• Narcosis
• Irregular cardiac activity
1.4. FIRE-PREVENTION MEASURES
Specific dangers for fires
Pressure increase
Special protection equipment for persons in
charge of fire-fighting
In the case of fire, wear breathing equipment with independent air intake.
Further information Use extinguishing systems that are compatible with the local situation and the surrounding
environment. Cool the containers/tanks using jets of water.
1.5. MEASURES IN CASE OF ACCIDENTAL RELEASE
Environmental precautions
Do not disperse into the environment
Cleaning methods
Evaporates
1.6. HANDLING AND STORAGE
H
ANDLING
Recommendations for safe handling • 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.
STORAGE
Requisites of the warehouse and the
containers
Keep the containers hermetically closed in a dry, well-ventillated environment. Keep in original
containers.
Indications for storage with other products
There are no materials that must be specifically mentioned.
CONSIDERATIONS REGARDING DISPOSAL
Product
Can be used after re-conditioning
Contaminated containers
The de-pressured containers must be returned to the supplier
