Control Technology for Worker Exposure to Coke Oven Emissions

摘要

Numerous studies have shown 'coal tar' products increase the risk of skin and lung cancer. One study showed top side coke oven workers had a lung mortality rate of 10 times that of all steel workers. Another study showed that men employed at coke ovens for more than five years showed a mortality rate 3.5 times the expected rate. In view of this significant health hazard to thousands of coke oven workers a NIOSH in-house study to assess coke oven control technology was performed. Control technology for coke ovens was assessed through visits to seven United States coke oven plants with state-of-the-art control technology and by a review of current coke oven control technology literature. Each control method is briefly described and the effectiveness of import engineering and work practice controls is presented. The report discusses, separately, controls for charging emissions, pushing emissions, door emissions, and top side leaks.
