Control of Gun Fumes in M4 Series Medium Tanks by Positive-Pressure Ventilation

摘要

The purpose of the report is to determine the degree of improvement in control of the gun fume hazard in the M4 series of medium tanks resulting from conversion of the crew compartment ventilation from the negative-pressure type to positive-pressure. An opportunity was presented in connection with the experimental development of a gas-proof tank to determine the benefits of positive-pressure ventilation from the standpoint of control of gun fumes.
