MSA 461100 Respirator with Protective Boot and Neoprene Holster

The W65 Self-Rescuer Respirator provides emergency respiratory protection against carbon monoxide gas resulting from under- ground fires or explosions. A onetime-use device for escape purposes only, it provides respiratory protection against carbon monoxide in otherwise respirable air; it should not be used in atmospheres containing less than 19.5 percent oxygen or in atmospheres containing other toxic gases and vapors. 

The W65 Self-Rescuer uses oxidation Hopcalite® Catalyst to convert toxic carbon monoxide to non-toxic carbon dioxide. Filter unit consists of an outer course-dust filter and an inner fine-dust filter to remove dust particles, the Hopcalite Catalyst, and a drying agent to protect the catalyst from moisture. The respirator exceeds NIOSH specified service-life requirements of 60 minutes against 1% carbon monoxide in air 25˚ C, 95% RH, at a continuous flow rate of 32 liters per minute. Tests at 2% CO show that the W65 Self-Rescuer will still afford protection, but that increased reaction heat will eventually force the wearer to retreat to an atmosphere with a lower CO concentration. Heat buildup caused by the oxidation reaction is inherent in the operation of this type of selfrecuer unit, but the W65 Self-Rescuer's integral heat exchanger reduces inhaled air temperature to a bearable level.
