Abstract
This article brings information on how to protect worker health during the decommissioning of mercury-based electrolysis facilities. It relies on the Euro Chlor document "Health 2, Code of practice, Control of worker exposure to mercury in the chlor-alkali industry" that provides protection guidelines for both normal production and decommissioning activities, and on hands-on experience gained during chlor-alkali plant decommissioning operations.
Decommissioning and dismantling of mercury-containing chlorine production plants presents challenges to industrial hygiene and health protection that are usually not present during normal operations. These involve meticulous training and enforcement of the appropriate use of personal protective equipment to prevent excessive mercury exposure.
The best practice guidelines and recommendations available from Euro Chlor can help employers and occupational physicians to manage these challenges, as they provide state-of-the-art procedures. Our experience is that rigorous implementation of these procedures and worker training ensured acceptable hygiene at the workplace and prevented mercury-related adverse health effects.
