Safety in Hazardous or Ex areas is a MUST

Constant technological developments and industrial automation have increased the need for electrical and electronic equipment in hazardous or Ex areas.

It is in the interest of industry, governments and workers that Ex Areas be regulated so as to be as safe as possible.

Safety in hazardous areas is non-negotiable. When equipment is not installed, maintained, inspected or repaired according to strict Ex standards by competent persons, the outcome can be devastating.

What may be tolerable in non-explosive atmospheres can directly lead to explosions that not only destroy property but can cost human lives or cause severe injuries.
