Hazardous substances can contaminate land, drains, sewers, rivers and the air.
They should never be mixed with general (non-hazardous) waste, or poured down drains or sinks, onto the ground, or buried, burnt or fly tipped.
Highly flammable liquids
Highly flammable liquids (HFLs), such as thinners, solvents, petrol and adhesives, can be easily ignited, catch fire and burn fiercely.
If you have to use HFLs you must make sure of the following.
- Check there are no naked flames or other sources of ignition nearby.
- Only take the amount you need for your immediate needs.
- Always follow the storage procedures.
- Have the correct fire extinguisher at hand and make sure you are trained to use it.
Liquefied petroleum gas
Liquefied petroleum gas (LPG) is a form of highly flammable gases held under high pressure to liquefy them. They will readily evaporate if released from the pressure vessel (cylinder). LPG is heavier than air so will sink into excavations, basements, drains and so on.
LPG cylinders must be stored upright in a well-ventilated area and in a secure cage. There are separate regulations covering the safe carriage of LPG cylinders in vehicles.
LPG has a distinctive smell. If you think there
- Others are warned to evacuate the area.
- The following is carried out, only if it is safe to do so.
- Turn the cylinder supply valve off.
- Open doors and windows.
- Remove any source of ignition. Do not allow the switching (on or off) of electrical apparatus.
- It is reported immediately.
