The mercury management program followed at CEMA Limbasi goes beyond the Indian legal requirements and has been studied by the Central Pollution Control Board, India, as a best practice in the lamp industry.


The program has 8 elements including exposure assessment and monitoring. Qualitative Exposure Assessments are an essential tool for predicting the potential exposure of an employee; quantitative air and biological monitoring are used to evaluate the actual exposure for a worker and are used as key indicators to the plant’s compliance with the Mercury Management Program.

Engineering Controls

Engineering controls such as Local Exhaust Ventilators (LEV), use of Respiratory Protective Equipment, regular maintenance activity and stringent waste handling norms are other aspects of the program.

Contaminated waste

Mercury contaminated waste from the manufacturing operation is collected separately and sent to a government authorized facility for incineration or secured landfill after solidification and stabilization.
