NIOSH 1982 Jan:8 pages
A visit was made to the Cambridge Tile Manufacturing Company, Cincinnati, Ohio to evaluate methods used to control hazardous conditions arising during the manufacturing process. Particular attention was given to controlling exposures to harmful chemical agents, silica (7631869), noise and excessive heat. The company manufactured 20,000 square feet of tile per day including nonrefractory tiles. A fabric stocking type sleeve between railroad car and underground hopper was used to control emissions during bulk material unloading. Two bag type dust collectors equipped with self cleaning mechanisms were in use. Air driven ball vibrators were used on the surge tanks. Closed tube conveyors were well maintained. Dubois automatic mechanical power presses were equipped with shuttle transfers and each had a local exhaust system with blast gates. A 3M-W2940 air hat was worn by the employee formulating glazes. Respirator wearers were subjected to pulmonary function testing. Blood lead (7439921) levels were checked every 3 months for employees who formulate glazes. All employees received a chest x-ray every 2 years. Other personal protective equipment was available. The author concludes that the safety precautions in place at this facility were good. There were several portions of the system which would be applicable for an in depth evaluation unless better examples can be found in other on site visits.
