When working in a hazardous or dangerous environment, it is imperative to use an intrinsically safe, safety-approved lighting tool. Whether working in a Class I oil refinery or in the silo of a Class III textile mill, safety is always a concern. Your light shouldn’t add to your worries.
When a light is referred to as ‘intrinsically safe’, it means that the torch is designed to eliminate the generation of sparks that have enough energy to ignite the surrounding material. Intrinsic safety also protects a light against abnormally high temperatures, meaning that if there was an internal shortage inside the light, the temperature of the components will not rise above the normal operating temperature. In intrinsically safe torches safety measures are put in place to ensure that no component of the torch can reach a temperature that would ignite the hazardous materials in the surrounding atmosphere.
Safety-approved lighting solutions should be specifically suited to the specialized requirements of the fire and emergency services industry and designed to ensure that the highest safety standards are met even in the most hazardous of work environments.
Hazardous locations are identified as areas where fire or explosive threats may exist due to the presence of flammable gases, vapors or liquids, combustible dusts or ignitable fibers. These locations are classified according to the properties of the hazardous materials and the likelihood of flammable concentrations being present. There are different classes and divisions of hazardous materials and environments and safety-approved lights are certified to different levels to meet the varying uses and requirements and users should confirm that the light they intend to use has the correct approval for the area it will be used in.
Torches and lights should betested and approved by the world’s leading independent laboratories and undergo a series of rigorous tests to ensure maximum user safety. IECEx is a certification scheme championed by the International Electro-Technical Commission, or ‘IEC’, and is the preferred certification for the international safety certification of lights used within all hazardous areas.
Some of the safety features of approved torches include:
- O-Ring Seal: Prevents vapors and gases from entering the body of the flashlight and being ignited by a switch spark.
- One-Way Purge Valve: Allows hydrogen to escape from the flashlight’s body.
- Hydrogen-Absorbing Pellets in Lamp Modules: A back-up system that absorbs any residual hydrogen retained inside the flashlight. No gas means no spark.
- Battery Polarity Tray: Makes operating a flashlight impossible if one or more batteries are inverted.
The latest light in the Pelican safety approved lighting range is the 3325 LED Helmet torch, a compact, lightweight and waterproof torch designed to fit neatly onto a helmet. The light is equipped with a rear-mounted switch for easy one-handed operation and an optional helmet mount allowing for a hands-free lighting option. The 3325 torch is IECEx certified for use in hazardous environments and emits a bright light of 160 lumens with an exceptional 16 hour run time.
