Detection and Diagnosis of faults in Coke Oven using Wireless LAN Communication at Steel Works

Unexpected cause of raised benzene absorption in coke oven by-product workers.

BACKGROUND Urinary biological monitoring for benzene (by measuring benzene metabolites) in coke oven by-product workers produced the unexpected result that 2 out of 10 employees had significantly raised urinary S-phenylmercapturic acid (S-PMA). However, simultaneous personal air sampling showed no excessive airborne exposure. METHODS Possible causes for this finding were investigated having e...

Effects of coke oven emissions and benzo[a]pyrene on blood pressure and electrocardiogram in coke oven workers

OBJECTIVE To evaluate the effects of occupational exposures to coke oven emissions (COEs) and benzo[a]pyrene (B[a]P) on the prevalence of hypertension and abnormal electrocardiogram (ECG) in coke oven workers. METHODS We included 880 coke oven workers and 710 oxygen employees in the exposed and control groups, respectively. Blood pressure (BP), ECG, blood lipid levels, and glucose levels of a...

Mortality in retired coke oven plant workers.

A previous study on 536 retired coke oven plant workers in Lorraine Collieries (France) reported an excess of deaths from lung cancer (standardised mortality ratio (SMR) = 251) compared with the French male population. Occupational exposures during working life were retraced for each subject, but the number of deaths during the observation period (1963-82) was small, and smoking habits were kno...

Cancer mortality among coke oven workers.

The OSHA standard for coke oven emissions, which went into effect in January 1977, sets a permissible exposure limit to coke oven emissions of 150 micrograms/m3 benzene-soluble fraction of total particulate matter (BSFTPM). Review of the epidemiologic evidence for the standard indicates an excess relative risk for lung cancer as high as 16-fold in topside coke oven workers with 15 years of expo...
