Electrical Safety Devices Go Beyond Fire and Security


When you think of electrical safety devices, what usually comes to mind are fire and security alarms, horns, strobes, and exit lights. But there are many other devices and instruments that are used to protect buildings and their occupants.


These devices can include, among many others:

  • Switches that turn off equipment and/or send an alert to prevent the equipment from reaching dangerous temperature or pressure levels

  • Oxygen analyzers that detect when O2 levels are too high or too low.

  • Level transmitters or level switches that stop a tank from filling and alert when fluid or bulk solid levels become too high

  • Flow switches that monitor flow rate and trigger alarms and corrective actions when a problem is detected

  • Color-coded hazardous location signals and strobe warning lights that alert occupants to restricted areas, hazardous conditions, and impending danger

  • Emergency stop, or E-stop, switches that can be activated to cut electrical power to machinery when dangerous situations occur

A hazard and operability (HAZOP) study can identify potential dangers in new designs and existing processes and help determine which electrical devices are best suited for each situation. Omni has participated in numerous HAZOP studies and can assist clients as needed.
