Special Fire Fighting Procedures
Fire exposed containers should be kept cool with water sprays.
Usual Fire and Explosion Hazards
Will decompose in contact with high temperature sources, i.e. flames, electric arcs, etc. to produce irritating
and highly toxic acidic products. Breathing apparatus should be worn if refrigerant is exposed to fire
conditions. Containers may burst if overheated.
Precautions in Handling and Use
General Precautions
Atmospheric levels should be minimised and kept as low as reasonably practicable below hygiene standard.
Avoid inhalation of high concentrations of vapour. Heavy vapour collects at low levels. Ventilate by extraction
at lowest level. Decomposes in flames, arcs and at red heat to toxic acid by-products. Avoid contact between
liquid and skin or eyes.
Ventilation Requirements
Ventilation may be required to achieve a sufficiently
low exposure level. Extract at lowest level. Vapour
collects in pits, trenches, basements, sewers and in
confined spaces and vessels. Respiratory Protection
Where doubt exists on atmospheric concentration and
particularly in confined spaces, self-contained
breathing apparatus should be considered. Breathing
apparatus should always be worn in a fire situation.
Protective Clothes
Where liquid splash is a possibility gloves suitable
for use in low temperatures should be worn e.g.
chlorobutyl rubber with cotton liners.
Overalls. Eye Protection
Goggles.
Storage
Containers should be stored in a cool dry place away from fire risk and sources of heat. They should not be
exposed to direct radiation from sources of heat such as steam or electric radiators. Do not heat containers
beyond 45
