The Streamlight 3AA ProPolymer® HAZ-LO®
7 LED is intrinsically safe in explosive gas atmospheres (not safe for mines
susceptible to firedamp*). It is ATEX-rated
for Category 1GD (Zone 0 and 20) locations, IECEx-rated for Zone 0 and 20,
Group IIC and IIIC locations, and it’s RoHS compliant. These safety ratings are made possible by an
anti-static body, a metal tray that prevents over-tightening of the set screw
and polarity protection that ensures correct battery installation and denies
power if the batteries are incorrectly installed. So the 7 bright LEDs can safely provide 500
candela of peak beam intensity for up to 24 hours. http://www.flashlightdistributor.com/Streamlight.aspx?Streamlight=68772
