- Abstract
- A protective garment or suit made of fluid impermeable material for use by workers in toxic and hostile environment having an air cooling device that divides air from a single airline supply into two separate fractions via dveice one via conduit to provide respiratory air at the proper volume and pressure to a breathing mask and the other via conduit to provide cooling air at the proper volume and presure 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 by a valve while preventing it from being reduced below a predetermined safe minimum volumetric flow.
