Dear Mr. Batchelar:
This is in response to your letter dated January 18, 1978, addressed to Secretary of Labor Ray Marshall, concerning the recent grain elevator explosions. Your letter was forwarded to this office for response.
The AP wire story you mentioned referred to our Grain Elevator Industry Hazard Alert (copy enclosed). It urges employers to take immediate appropriate actions to safeguard their employees. You will find on page 4 of the Alert that slipping belts on bucket elevators and other conveyors and slipping V-belts are indicated as major fire ignition sources in grain elevators.
Thank you for forwarding the news release and descriptive literature which indicates that a non-friction alternative drive system is available to employers desiring to eliminate the potential hazards of slipping belts. This type system will be given consideration in the development of safety standards for this industry. We are currently working with the industry, Federal and State officials, union officials and other knowledgeable individuals to learn more about grain dust hazards. Hopefully, our efforts will result in determining the causes of these tragedies and bring an early solution for their elimination.
Thank you for your concern in this matter. Your suggestion to discuss this matter in greater detail will be accepted in the near future, when our investigation of these explosions has been completed.
If I may be of any further assistance, please feel free to contact me.
