Safety Approvals and Testing

Energizer Lights are tested for use in the toughest and most abusive environments. Our products experience real-world situational testing before you ever pick one up, including:

  • Concrete drop-testing
  • Temperature and humidity testing
  • UV degradation testing
  • Water testing
  • Switch testing
  • Field evaluations (e.g. extreme, military field testing)
Intrinsically Safe Flashlights 

The Energizer family of intrinsically-safe LED lights have more certifications and agency approvals than any light in their class, and provide a low cost of ownership over the lifespan of the light.  Rugged durability and extremely long runtimes are just some of the key benefits of these lights. 

Intrinsic safety is unique explosion protection compared to other explosion protections.  In other types of explosion protection, care is taken to confine the ignition source (spark or excess heat) within the device to prevent it from contacting the hazardous material.  Intrinsically safe protection requires the device be incapable of creating a spark or heat sufficient to cause ignition of the hazardous material.

The levels of safety protection are expressed by:
  • The proximity to and duration of hazardous environment exposure (area classification – see tables below).
  • The class of hazard encountered (class – see tables below):
    - Class I: Flammable gases, vapors, or liquids
    - Class II: Combustible dusts
    - Class III: Ignitable fibers and flyings
  • The specific hazard encountered (groups – see tables below).
  • The maximum potential surface temperature the flashlight can produce (temperature codes – see tables below).
Levels of Safety Protection

For more in-depth information on the levels, review these tables. 




Division 1:
Where ignitable concentrations of the hazardous material can exist all the time or some of the time under normal operating conditions.

Zone 0:

Where ignitable concentrations of the hazardous material are present continuously or for long periods of time under normal operating conditions.

Zone 1:

Where ignitable concentrations of the hazardous material are likely to exist under normal operating conditions.

Division 2:

Where ignitable concentrations of the hazardous material are not likely to exist under normal operating conditions.

Zone 2:

Where ignitable concentrations of the hazardous material are not likely to exist under normal operating conditions.

Related Definitions

The following definitions, organizations, and standards are related to safety protection and Energizer’s testing of lighting products.

Mine Safety and Health Administration - for use in USA mines; approved for methane-air mixtures.

International Electrotechnical Commission (IEC) - scheme for certification to standards relating to equipment for use in explosive atmospheres.

UL and cUL
Underwriters Laboratories / Canadian Underwriters Laboratories - Independent labs which certify that the flashlight designs meet the required safety standards to achieve a specified level of hazardous location protection according to UL (primarily USA) and cUL (primarily Canada) safety standards.

The Directives are known as ATEX (from the French – ATmospheres EXplosibles).  Since July 1, 2003, all new equipment intended for use in potentially explosive atmospheres must comply with ATEX Directive 94/9/EC, introduced under Article 100a of the Treaty of Rome. The Directive applies to any equipment that will or may be used in an explosive atmosphere. Manufacturers must design and test components to prevent or minimize the risk of explosion due to the production or release of explosive atmospheres.

Essentially, manufacturers must consider every possible electrical or non-electrical source of ignition. And, at the same time, consider all potentially hazardous environments a product could operate in; the different ways it could be applied and the technical ability of the person using the product.  All equipment within the scope of the Directive must comply with the requirements of the Directive and bear the Ex Mark and CE Marking in order to be placed on the market or put into service within the EU.

  • Equipment Group I (mining)
  • Equipment Group II (non-mining)
