HANDLING
Avoid inhalation of high concentrations of vapours. Atmospheric level
should be controlled in compliance with the occupational exposure limit.
Atmosphere 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 with naked flames and hot surfaces as corrosive and very
toxic decomposition products can be formed.
Avoid contact between the liquid and skin and eyes.
For correct refrigerant composition, systems should be changed using the
liquid phase and not the vapour phase.
Process Hazards
Liquid refrigerant transfers between refrigerant containers and to and
from systems can result in static generation. Ensur adequate earthling.
Certain mixtures of HFCs and chlorine may be flammable or reactive under
certain conditions.
STORAGE
Keep in a cool place away from fire risk , direct sunlight and all sources
of heat such as electric and steam radiators. Avoid storing near to the
intake of air conditioning units, boiler units and open drains.
Cylinders and Drums:
Keep container dry.
Storage temperature(Deg C): < 45

PROTECTION
Wear suitable protective clothing , gloves and eye /face protection. Wear
thermal insulating gloves when handling liquefied gases. In cases of
insufficient ventilation, where exposure to high concentrations of vapour
I possible, suitable respiratory protective equipment with positive air
supply should be used.
