APPENDIX: SAFETY DATA R410A
Refrigerant Data
Safety Data: R410A
General Precautions
Do not inhale concentrated vapours. Their concentration in the atmosphere should
not exceed the minimum preset values and should be maintained below the
professional threshold. Being weightier than the air, the vapour concentrates on the
bottom, in narrow areas. T here fore, the exhaust system must work at low level.
Respiratory System Protection
If you are in doubt about the concentration in the atmosphere, it is recommended to
wear a respirator approved by an accident prevention Authority, of the independent
or oxygen type.
Storage
Cylinders must be stored in a cool, dry and properly ventilated storage area away
from heat, flames, corrosive chemicals, flumes, explosives and be otherwise
protected from damage. Keep a temperature below 52°C.
Protective Clothing
Wear overalls, protective gloves and goggles or a mask.
Accidental Release Measures
IIt is important to wear protective clothing and a respirator. Stop the source of the
leak, if you can do this without danger. Negligible leaks can be left evaporating under
the sun, providing that the room is well ventilated. Considerable leaks: ventilate the
room. Reduce the leak with sand, earth or other absorbing substances. Make sure
that the liquid does is not channelled into gutters, sewers or pits where the vapours
are likely to create a stuffy atmosphere.
Disposal
The best method is recovery and recycling. If this method is not practicable, dispose
according to an approved procedure, which shall ensure the absorption and
neutralization of acids and toxic agents.
Fire Fighting Information
R410A: Not flammable in the atmosphere.
Cylinders
The cylinders, if exposed to fire, shall be cooled by water jets; otherwise, if heated,
they may explode.
Protective Fire Fighting Equipment
In case of fire, wear an independent respirator and protective clothing.
