halogenated hydro-carbons (e.g. as contained in

aerosols, paints, solvents and cleaning agents)

HDo not use a room subject to high levels of dust

HDo not use a room subject to permanently high humidity

HThe room should be frost-protected

HMax. ambient temperature 95°F (35°C).

HProvide good ventilation and do not close or obstruct

vents (if installed).
