Sensear's Intrinsically Safe headsets and earplugs now have system-level certification when connected to Kenwood Intrinsically Safe radios.

How Intrinsic Safety Works

In order to prevent explosions and perilous hazards from occurring on the job, intrinsically safe headsets need to limit the electrical and thermal energy within the electrical circuits to a level below that which will ignite the gases or dusts. This prevents electrical sparks and keeps the temperature of the headsets low. This foolproofs electrical circuits, making it possible for users to navigate in potentially explosive environments.

UL and CSA

UL or Underwriter Laboratories is an independent organization endorsed by OSHA that tests and certifies product safety in North America. UL evaluates compliance of products, components, materials, and systems against a specific set of standards that is often updated. The UL mark, therefore, can only be used if the products meet the standards.

UL 913 is the typical standard for Intrinsically Safe Headsets for use in Class I, II, and III, Division 1, Hazardous (Classified) Locations. We will dive into Classes and Divisions in the next blog, but there are two systems in place in North America hazardous locations: the Division system and the Zone system. Below are typical labels for each system:

CSA stands for the Canadian Standards Association; however, it is a global provider of certification services, recognized throughout North America and Europe. It is very similar to UL, testing products for businesses to see how they respond to certain environments or situations. The only difference between the CSA and UL is that UL only applies to the U.S and Canada (C – UL). Therefore, if you want to export your product, CSA is the better option as it is recognized globally, whereas UL is the better option if you are only selling in North America.

Who Needs IS Headsets?

Everyone should care about intrinsic safety, but not everyone needs intrinsically safe headsets. Those who primarily need intrinsically safe equipment/headsets are managers of industrial manufacturing environments, employers operating oil or gas companies, and other plants comprised of possible safety hazards. Keeping employees safe should always be the top priority of any organization in hazardous environments.

Sensear has announced the arrival of the SM1R, an industrial headset built specifically to enhance two-way radio communication in high-noise environments.  The headset is unique from the rest of Sensear’s portfolio iin that it contains no battery and instead is powered by the radio, making the unit lighter and more comfortable for the user. 

Similar to the rest of Sensear’s portfolio, the headset pairs Sensear’s patented SENS® technology and a noise-cancelling boom mic to allow users in high-noise environments to communicate either via face-to-face or two-way radios while maintaining 360° audible awareness of their surroundings and protecting their hearing.   The SM1R will be compatible with many of the most popular radios in the marketplace today from manufacturers such as Motorola, Kenwood, Harris, Hytera, ICOM, Vertex, and Tait.  This is the 1st product Sensear builds specifically for the two-way radio market, using the battery of the radio to power the unit.
