R32 refrigerant fluid
Emergency number: INRS/ORFILA poison control 330145425959
Effects harmful to health:
The vapours are heavier than air and may lead to asphyxia owing to reduced oxygen levels.
Liquefied gas: contact with the liquid may cause serious frost burn and eye injuries.
Flammability risk as per the concentration in air.
R32 (difluoromethane CH2F2) is a methane molecule that has 2 chlorine atoms in place of 2 hydrogen atoms.
Because it is used PURE and not mixed with other substances, R32 also has the advantage of not breaking down in
the refrigerant circuit, which can cause a loss of efficiency.

First aid
If inhaled:
-Remove the subject from the contaminated area and to fresh air.
-In case of sickness: contact a doctor.
In case of skin contact:
-Treat frost burn like an ordinary burn. Rinse with plenty of warm water, do not remove
clothing (risk of sticking to the skin).
-If burns occur, contact a doctor immediately.
In case of contact with the eyes:
-Rinse with water immediately, holding the eyelids apart (at least 15 minutes).
-Consult an ophthalmologist immediately.
Fire prevention
measures
-Suitable extinguishing agents: all extinguishing agents can be used.
-Unsuitable extinguishing agents: none known. In the event of fire nearby, use the
appropriate extinguishing agents.
-Pressure elevation: in the presence of air, a flammable mixture may form under certain
temperature and pressure conditions.
-Effect of heat: release of toxic and corrosive vapours.
-Special intervention methods: cool the volumes exposed to heat with water spray.
-firefighter protection:
-Full self-contained breathing apparatus.
-Full body protection.
In case of
accidental
dispersal
Individual precautions:
-Avoid contact with eyes and skin.
-Do not intervene without suitable protective equipment.
-Do not breathe vapour.
-Evacuate the danger zone.
-Stop the leak.
-Eliminate all ignition sources.
-Mechanically ventilate the spillage zone.
Cleaning/decontamination: allow any residual product to evaporate.
In case of eye contact: rinse with water immediately, holding the eyelids apart (at least 15
minutes).
Consult an ophthalmologist immediately.
Handling
-Technical measures: ventilation
-Precautions to be taken
-No smoking.
-Prevent the build-up of electrostatic charges.
-Work in a well ventilated place.
Personal
protection
-Respiratory protection:
-If ventilation is insufficient: AX type cartridge mask.
-In confined spaces: self-contained breathing apparatus.
-Hand protection: protective gloves in leather or nitrile rubber.
-Skin protection: clothing made mostly of cotton.
-Industrial hygiene: do not drink, eat or smoke in the workplace.
Disposal
recommendations
Important
Disposal must comply with applicable local and national regulations.
-Product waste: consult the manufacturer or the supplier for information on recovery or
recycling.
-Soiled packaging: reuse after decontamination. Destroy in authorised installations.
