What is an intrinsically safe light?
 
When you're in a potentially hazardous environment, using a flashlight that is rated with safety approvals is vital.
 
Intrinsically safe lights are designed to eliminate "the spark" which can cause explosions in and around flammable conditions. Intrinsically safe lights are rated by Class, Division and Group. These ratings inform users under what conditions the light will NOT be the source of "the spark" which can cause an explosion. For example, a Class 1, Division 1, Group D, E and F is a commonly required rating for the petrochemical industry, where specific types of flammable vapors may be present.
