Hazardous reactions May react violently with sodium, potassium, barium and other alkali and
alkaline earth metals. Incompatible materials : Magnesium and alloys
containing more then 2% magnesium.
Hazardous decomposition products R22: Halogen acids formed by
thermal decomposition.
R407C: Halogen acids by thermal
decomposition and hydrolysis.
General precautions Avoid inhalation of high concentrations of vapours. 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
spillages to evaporate provided there is suitable ventilation.
Large spillages : Ventilate area. Contain spillages 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.
