When plastics or chemicals burn, they often produce toxic smoke and fumes. Whereas fire fighters are usually equipped with professional respiratory protection equipment, this is not necessarily the case for fire investigators. Particularly when the investigation begins shortly after the fire, it is absolutely necessary that the investigators be equipped with appropriate respiratory protection equipment. The 3M Jupiter Powered Air Respirator System has proven itself for such applications. It offers a high level of protection without hampering the investigator.Both the helmet and the belt mounted motor blower unit of the 3M Jupiter Powered Air Respirator System are light, compact and easy to use. One more advantage of the Jupiter Powered-Air-Respirator: even when wearing the helmet, the investigator has no problem taking photographs, filming, or dictating.
