Gentlemen - Military environments that are "closed" have required the use of "Limited Fire Hazard" wire/cables/accessories since 1981/1982, and their importance rose after real-life problems in the Falklands war. There are UK Defence Standards that cover the requirements in detail (try http://www.dstan.mod.uk/data/standev/61e.php as a starting point if you want to look).

You will be hard pressed to find governmental regulations requiring halogen free electronics. Even the definition of halogen free is not firmly set. Randall Flinders gave a presentation on halogen free electronics at the 2008 IEEE Product Safety Engineering Society symposium. If you or somebody within Schneider Electric have access to the symposium CB, pull up Mr. Flinders' presentation for more information. The presentation gives a good overview. I can also recommend checking with the APC division of Schneider Electric. A lot of the concern over halogens in electronics comes from the resulting combustion products. There is some push towards halogen free wiring in data centers because of the concern of the hydrochloric acid that could result from combustion. This in turn can corrode electronics in areas of the data center unaffected by the fire. There are likely groups within APC that have done research on this subject.

Can anyone point me to Standards/Legislation as to when/where LSZH Cables are and are not required?
