People that work in hazardous areas know that when electrical equipment and any other instruments are exposed to this type of environment they must be placed within an intrinsically safe barrier. This is to ensure that they have a safe working environment and that they also protect those nearby against risks from explosions. 

Intrinsically safe cord reels are absolutely essential in hazardous areas. Intrinsic safety is a protection technique for the safe operation of electrical and electronic equipment in hazardous areas where any ignition source needs to be eliminated. They are essentially sealed to be regarded as intrinsically safe that will protect them from damage, external electrical or magnetic fields, and be isolated from any other non-intrinsically safe cord reels.
