       Flashlight Explosions Pose Threat to Workers
       =============================================

In a June 1997 Fact Sheet, NIOSH reports that flashlights can explode while
in the hands of workers if the instruments are misused.

Most of the batteries commonly used in flashlights produce hydrogen gas when
the zinc electrode in the batteries corrodes. If hydrogen gas accumulates
within batteries or battery compartments and cannot be released, it builds
up pressure and can cause the battery to rupture. A mixture of hydrogen gas
and oxygen is highly explosive and, if ignited by a spark or excessive heat,
can cause a powerful explosion.

Excess hydrogen gas is more likely to be created if batteries are used
incorrectly. In order to protect themselves, workers should follow these
precautions:

   - Read and follow the manufacturer's recommendations for product use.
   - Do not mix batteries of different brands.
   - Do not mix old and new batteries; if a flashlight grows weak, replace
     all the batteries in it.
   - Do not use damaged batteries.
   - When you install batteries, be sure to put them in according to the
     polarity indicated.
   - Before you use approved battery-powered flashlights in flammable
     atmospheres, inspect them to ensure that the batteries are in good
     condition, and that the proper batteries are installed correctly. If
     you open the battery compartment, that should allow any accumulated
     hydrogen gas to dissipate. But do not inspect the flashlight in a
     hazardous area or near an open flame.
