Special protective equipment and
precautions for fire fighters
In case of fire: Stop leak if safe to do so.
Continue water spray from protected position until container
stays cool.
In confined space use self-contained breathing apparatus (open-
circuit positive pressure compressed air type) in combination
with fire kit.
Thermal decomposition will evolve very toxic and corrosive
vapors (hydrogen fluoride).
HFC 134a is not flammable in air under ambient condition of
temperature and pressure.
Certain mixtures of HFC 134a and air when under pressure
maybe flammable.
Certain mixtures of HFCs and chlorine may be flammable or
reactive under certain conditions.
Safety gloves and shoes, or boots, should be worn when
handling cylinders.
