An Intrinsically safe headlamp is often used by workers in underground mining, search and rescue, surgeons, and others who need hands-free lighting. In the same way, those working in potentially explosive environments should use only the safest and most reliable equipment available.

What does intrinsically safe mean? It means that the flashlight design will not produce sparks, or at least not enough sparks with the energy to ignite its surroundings.

Additionally, typical certifications include ATEX, IECEx, and MSHA listing as intrinsically safe permissible.

Features to look out for:

  • LED technology – 50,000 + hours LED life
  • Spotlight – High/Low-brightness white floodlight – red floodlight
  • Focused spotlight beam for distance illumination
  • Red colored floodlight for preservation of night vision (optional)
  • Engineered polymer housing
  • Adjustable ratchet tilt head
  • Non-slip elastic head strap
  • Heavy-duty rubber strap for hard hat applications
  • Waterproof with higher rating preferred
  • Impact & chemical resistant

Due to the difficulty of passing Intrinsically Safe certification, many similar products still use incandescent bulbs. So, look for an output with LED emitters.

What battery should I use?

Intrinsically safe batteries come in various chemistries, including rechargeable Li-ion, NiCd, and lithium-thionyl chloride (Li-SOCl2). In addition to the environmental conditions such as performance, life cycle, and weight, the battery pack design is a crucial factor to consider.

When working within flammable and potentially explosive conditions, one must take extra safety precautions. Workers should hold their electronic equipment, such as lamps, gas detectors, and air-monitoring devices, to the highest safety standards.
