NIOSH Testimony on Grain Handling Facilities; Safety Hazards by R. A. Lemen, June12-14, 1984.
NIOSH 1984 Jun:6 pages
Testimony was presented in support of the OSHA proposed rule on grain handling facilities with the intent of mitigating fires, explosions, and other safety hazards. A description was given of the publication Occupational Safety in Grain Elevators and Feed Mills, followed by identification of several areas of special need. The study concluded that all commodity generated dusts be considered hazardous until data demonstrated otherwise. The risk of explosions has been reduced in the industry through use of closed pneumatic systems to contain dusts. Worker and employer recognition of existing hazards was seen as vital. Entry into and working in confined spaces was to be prohibited until initial testing of the atmosphere in the space had been conducted. Reconsideration of the action level for layered grain dust was encouraged as the currently acceptable action level of 1/8 inch was thought to be excessive due to the fact that dust accumulations of as little as 1/64 inch have supported secondary explosions when uniformly dispersed into the air. Rule clarification or changes were suggested to ensure that use of compressed air cleaning was prohibited and that portable vacuum cleaners were used to remove accumulated dust only if precautions were made to ensure that no potential source of ignition existed due to their use. More effort was urged to acquaint workers with potential hazards of their industry. Mention was made of where to find information on selection and use of respiratory protective equipment.
