General precautions Avoid inhalation of high concentrations of vapors. Atmospheric concentrations
should be minimised and kept as low as reasonably practicable below the
Occupational exposure limit. The vapour is heavier than air and collects at low level
and in confined areas. Ventilate by extraction at lowest levels.
Respiratory protection Where doubt exists on atmospheric concentration, HSE approved breathing
apparatus should be worn. This should be self contained or of the long breather
type.
Storage Keep containers dry and in a cool place away from fire risk, direct sunlight, and all
sources of heat such as radiators. Keep at temperatures not exceeding 45 °C.
Protective clothing Wear overalls, impervious gloves and goggles/face protection.
Spill / Leak procedure Ensure suitable personal protective clothing and respiratory protection is worn.
Provided it is safe to do so, isolate the source of the leak. Allow small spillage’s to
evaporate provided there is suitable ventilation.
Large spillage’s : Ventilate area. Contain spillage’s with sand, earth or any suitable
absorbent material. Prevent liquid from entering drains, sewers, basements and
work pits since vapour may create a suffocating atmosphere.
Disposal Best to recover and recycle. If this is not possible, destruction is to be in an approved
facility which is equipped to absorb and neutralise acids and other toxic processing
products.
Fire extinguishing data R22: Non-flammable R407C: Non-flammable at atmospheric
conditions.
Containers Fire exposed containers should be kept cool with water sprays. Containers may
burst if overheated.
Fire fighting protective equipment Self contained breathing apparatus and protective clothing must be worn in fire
conditions.
