Diesel Vapours

Substances have more than one chemical property ie

Diesel Vapour is both flammable and toxic.
The most dangerous property is that it can be ignited to cause a fire or explosion when the vapours reach a certain concentration in air. It therefore would be classed as flammable.  This concentration of vapours can also be toxic but the primary or immediate danger would be fire or explosion.

Training can be conducted at:

  • Fire Safety Trainer practical training premises.
