ABSTRACT:
A protective garment or suit made of fluid impermeable material for use by workers in toxic and hostile environments having an air cooling deivce that divides air from a single airline supply into two separate fractions, one to provide respiratory air at the proper volume and pressure to a breathing mask and the other to provide cooling air at the proper volume and pressure to the inside of the suit to cool the body of the worker. The cooling device permits the delivery of different volumes of cooling air and respiratory air at the appropriate pressure. Further, the volumetric flow of respiratory air to the breathing mask can be adjusted by the worker while preventing it from being reduced below a predetermined safe minimum volumetric flow.
