Abstract
The effectiveness of respirators in grain elevators was evaluated. Six types of dust and mist respirators were tested. Particulate penetration was determined. Efficiencies for all filters were greater than 95 percent. Particle sizes ranged between 3 and 7 micrometers. A loading effect was seen on all filters, which increased their efficiency. The authors conclude that any of the respirators offers adequate protection in the grain elevator atmosphere. They suggest further testing in environments with heavier dust concentrations.
