===Safety regulations===
Industrial, marine, public safety, and military organizations develop specifications for flashlights in specialized roles. Typically, light output, overall dimensions, and battery compatibility and durability are required to meet minimum limits. Flashlights may be tested for impact resistance, water and chemical resistance, and the lifespan of the control switch.

Flashlights intended for use in hazardous areas with flammable gas or dust are tested to ensure they cannot set off an explosion.<ref>[http://www.energizerlightingproducts.com/technology/safety-approvals-testing/Pages/ansistandards.aspx Energizer Lighting Products Safety Approvals and Testing] {{webarchive|url=https://web.archive.org/web/20111102154259/http://www.energizerlightingproducts.com/technology/safety-approvals-testing/Pages/ansistandards.aspx |date=2011-11-02 }}.

Flashlights for hazardous areas may be designed to automatically disconnect the lamp if the bulb is broken, to prevent ignition of flammable gas.<ref>Underwriter's Laboratories Standard UL 783</ref>

Regulations for ships and aircraft specify the number and general properties of flashlights included as part of the standard safety equipment of the vessel. Flashlights for small boats may be required to be waterproof and to float.  Uniformed services may issue particular models of flashlights, or may provide minimum performance standards for their members to follow when purchasing their own flashlights.
