GHS hazard class · Physical hazards
Aerosols
Aerosols are spray dispensers (non-refillable containers made of metal, glass or plastic) holding a gas that is compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device. The GHS classifies them by flammability.
What it means
The contents may be flammable, and the pressurized container can burst if heated, even when it seems empty.
What to do
Do not spray on an open flame or other ignition source, keep away from heat and direct sunlight, do not pierce or burn the container even after use, and follow the supplier's maximum storage temperature.
This is general guidance for the class. Your product's safety data sheet takes precedence.
