When probable resources of release are discovered, the following move is to ascertain the grade of launch. The quality of launch categorises the nature and persistence of the flammable environment. This tends to support to determine the harmful zones:
Safety wherever potential ignition sources are made ineffective or separated in the explosive environment by immersing them in a very protecting liquid.
Ignition safety using mechanical or electrical equipment together with nonelectrical equipment to lessen the likelihood of a possible ignition more info source becoming helpful.
