Report of Visit to National Lime and Stone Company, Carey, Ohio.
Enviro Control, Inc., Rockville, Maryland 1977 May:8 pages
This report describes a meeting between officials from Enviro Control, Inc. (ECI), and the National Lime and Stone Company to discuss commercial coal gasification and the development of occupational safety and health guidelines for commercial coal gasifiers. The National Lime and Stone Company was one of two companies in the United States using a gasifier for the production of a low Btu gas for commercial uses. The visit revealed a small coal pile located above the bin grate for the gasifier elevator. It was evident that there was little dust connected with the truck dumping as there was very little coal dust on top of the white lime dust which coated everything in the facility. Gasifier air blowers were located on the first floor of the gasifier building. While the air blower was noisy, the noise level apparently did not exceed OSHA standards. Access hatches to the gasifier did not appear to be leaking. When the ash lockhopper or the soot hopper at the bottom of the cyclone was opened for dumping, producer gas did escape into the atmosphere. All workers wore hardhats, hard shoes, and safety glasses; dust masks and respirators were available. The workers were told of the carcinogenic nature of the coal tars and of the dangers of dealing with large quantities of carbon-monoxide (630080).
