Embodiment Construction

[0034] Referring first to Figures 8A and 8B, an apparatus 10 for protecting a user 58 in a contaminated environment comprises a hazardous materials "hazmat" protective suit 12 having a breathing apparatus 14 comprising a powered air purifying respirator "PAPR" 16 and self-contained breathing apparatus "SCBA" 18. It should be noted that the breathing apparatus 14 may be used with or without the protective clothing 12, but that the protective clothing 12 and the breathing apparatus 14 are generally capable of being used together to protect against chemical, fire, biological, nuclear and and / or other pollutants resulting in maximum protection in contaminated environments.

[0035] Referring now to FIGS. 1A and 1B , a first embodiment of a breathing apparatus 14 comprising a PAPR 16 and an SCBA 18 is shown in an exploded view ( FIG. 1A ) and a fully assembled view ( FIG. 1B ). A conventional harness 66 may be used to secure the various components of the breathing apparatus 14 and...

Abstract

An apparatus for protecting a user in a hazardous or contaminated environment caused by chemical, fire, biological, and / or nuclear contamination includes a selfcontained breathing apparatus (SCBA) for providing tank stored breathable air, a powered air purifying respirator (PAPR) for purifying ambient air and a valve system that can be used to control the source of air from either the SCBA or the PAPR. The source of breathable air can be selectively controlled via manual or automatic controls while a protective body suit can be operably coupled with the SCBA and the PAPR to protect a user within the contaminated environment.
