Section 4: First aid measures
4.1 Description of first aid measures
General notes: In all cases of doubt, or when symptoms persist, seek medical attention.
Following inhalation:
Remove patient from exposure, keep warm and at rest. Administer oxygen if necessary.
Apply artificial respiration if breathing has ceased or shows signs of failing.
In the event of cardiac arrest apply external cardiac massage. Obtain immediate medical attention.
Following skin contact:
Thaw affected areas with water. Remove contaminated clothing.
Caution: clothing may adhere to the skin in the case of freeze burns.
After contact with skin, wash immediately with plenty of warm water.
If irritation or blistering occur, obtain medical attention.
Following eye contact:
Immediately irrigate with eyewash solution or clean water, holding the eyelids apart, for at least 10
minutes. Obtain immediate medical attention.
Following ingestion:
Unlikely route of exposure. Do not induce vomiting.
Provided the patient is conscious, wash out mouth with water and give 200-300 ml (half a pint) of water to
drink. Obtain immediate medical attention.
Notes for the doctor:
Treat symptomatically and supportively.
Treatment may vary with condition of victim and specifics of incident.
4.2 Most important symptoms and effects, both acute and delayed
Inhalation Very high atmospheric concentrations may cause anaesthetic effects and asphyxiation. An
inhalation study in dogs has shown that HFC 32, unlike analogous substances, does not cause cardiac
sensitization at concentrations up to 35% v/v.
Skin Contact Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorption.
Eye Contact Liquid splashes or spray may cause freeze burns.
Ingestion Highly unlikely - but should this occur freeze burns will result.
4.3 Indication of the immediate medical attention and special treatment needed
Persons with pre-existing skin, eye, or respiratory disease may be at increased risk from the irritant or
allergic properties of this material. Attending physician should treat exposed patients symptomatically.

In case of fire in the surroundings: use appropriate extinguishing media.
Unsuitable extinguishing media:
For this substance/mixture no limitations of extinguishing agents are given.
5.2 Special hazards arising from the substance or mixture
Substance is combustible. Containers may burst if overheated.
Decomposition products may include the following materials: carbon dioxide, carbon monoxide,
halogenated compounds(hydrogen fluoride).
5.3 Advice for fire-fighters
Shut off gas supply if this can be done safely. If possible, take container out of dangerous zone.
Cool cylinders with water spray. Self-contained breathing apparatus (SCBA) may be required if cylinders
rupture or release under fire conditions.
Section 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Immediately contact emergency personnel. Keep unnecessary personnel away.
Use suitable protective equipment (section 8). Shut off gas supply if this can be done safely.
Isolate area until gas has dispersed.
6.2 Environmental precautions
Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
Discharge into the environment must be avoided.
6.3 Methods and material for containment and cleaning up
Allow small spillages to evaporate provided there is adequate ventilation.
Large spillages: Ventilate area. Contain spillages with sand, earth or any suitable adsorbent material.
Prevent liquid from entering drains, sewers, basements and work pits since the vapour may create an
explosive or suffocating atmosphere.
6.4 Reference to other sections
See Section 7 for information on safe handling.
See section 8 for information on personal protection equipment.
See Section 13 for information on disposal.
Section 7: Handling and storage
7.1 Precautions for safe handling
Keep away from sources of ignition - No Smoking.
Take precautionary measures against static discharges.

Avoid inhalation of high concentrations of vapours.
Atmospheric levels should be controlled in compliance with the occupational exposure limit.
Atmospheric concentrations well below the occupational exposure limit can be achieved by good
occupational hygiene practice.
The vapour is heavier than air, high concentrations may be produced at low levels where general
ventilation is poor, in such cases provide adequate ventilation or wear suitable respiratory protective
equipment with positive air supply.
Avoid contact between the liquid and skin and eyes.
7.2 Conditions for safe storage, including any incompatibilities
Keep in a well ventilated place. Keep in a cool place away from fire risk,…
