Cement Manufacturing Enforcement Initiative US EPA

The cement manufacturing industry was an EPA New Source Review/Prevention of Significant Deterioration (NSR/PSD) national enforcement initiative in fiscal years 2008-2010 and was continued as a Reducing Air Pollution from the Largest Sources national enforcement initiative for fiscal years 2011-2013. The cement sector is the third largest industrial source of pollution, emitting more than

Worker Safety Series Concrete Manufacturing

Concrete Manufacturing. More than 250,000 people work in concrete manufacturing. Over 10 percent of those workers 28,000 experienced a job-related injury or illness and 42 died in just one year.

Data were analyzed by the EXCEL software. Results: The highest sound pressure level in the Cement Plant (106 db) was recorded in the stone crushing units and the grinding units (mills); 14 units had a mean sound level above the permissible 85 db noise level. Conclusion: There are specific units with high noise exposure in the Kerman Cement plant.
