For Canadian industries that are exposed to combustible materials, such as vapours and dust, or flammable chemicals and gasses, all devices onsite must be designed so as to not become an inadvertent ignition factor. By nature, all electronic devices give off electrical sparking and excessive heat emissions. In certain situations, the sparks and heat can become combustible when exposed to flammable materials. This is why workplaces such as oil refineries, chemical processing plants, and manufacturing facilities choose certified Intrinsically Safe (IS) two way radios as their primary tool for safe and reliable communications.
Intrinsically Safe radios prevent combustion in hazardous environments by keeping the electrical and thermal energy of the device low enough to not spark combustible materials in the surrounding area. The internal structure employs strategic spacing between components to prevent short-circuiting. The external structure of the radio is designed to maintain low temperatures at all times with a fully encapsulated battery compartment and anti-static coverings to prevent static electricity build-up within and around the device.
A common mistake that companies make when using IS two way radios is not placing the same safety standards on their radio accessories. All aspects of the radio device and the system in which it is deployed should be certified Intrinsically Safe to avoid inadvertent exposure to ignition threats. Pairing a certified IS radio with non-IS accessories is like putting a patch on a HazMat suit – it may work for a bit but you’re leaving yourself exposed to potential dangers because you don’t have the right protection.
To save you time in looking up the accessories you need for your IS radios, here is a list of Motorola’s leading Canadian Standard Association Certified Intrinsically Safe two way radio accessories:
