Instructions specific to safe use
Intrinsic safety
Intrinsic Safety is an electronic hardware protection concept that ensures there
are no conditions under which the equipment can operate that could cause a
release of energy sufficient to ignite a flammable gas. Devices that meet these
design criteria are deemed Intrinsically Safe (IS).
Special design, testing, quality and inspection rules apply to manufacturers and
users of IS equipment due to the critical nature of their deployment in hazardous
areas. Areas where hazardous atmospheres exist are classified as Class,
Division or Zone depending on the country. Users should check local and
governmental safety policies as a minimum before installing this equipment in a
hazardous area or confined space.
