The necessities are meant to stop electrical tools from being the ignition resource for the flammable combination. Accordingly, the installation itself has to be explosion-evidence.
Areas are classified in accordance with the type and Qualities in the combustible content as well as chance that an ignitable combination will exists.
Zone one: Prone to have ignitable concentrations of flammable gases or vapors under ordinary running situations.
