headaches. In one of the studies, worker with exposure to manganese exhibited aggressive and  destructive behaviour and strange compulsive behaviours like uncontrolled laughter or impulse dancing and singing. These patient were aware of their strange behaviour but were unable to control it.

At looking at this research, it is very     unclear what is the safe level on Manganese in our bodies before any long-term health effects are noticeable or become permanent. It seem like the only true measure of a chronic condition is by    undergoing an MRI that will diagnose magnesium.

Based on the research that I have        observed, one can only conclude that all workers in the Zinc Operation should minimize manganese exposure to the lowest possible level. I would encourage all manganese-exposed workers to practice good hygiene and to not expect an MnO2 dusty work environments. Efforts are ongoing to reduce Cellhouse workers to manganese exposure. However, until these projects are completed inform your supervisor immediately if your work area requires vacuuming or washing.

Zinc Ergo Projects

Over the last few months, many workers in the Zinc Cellhouse have expressed concerns over the increased job demand and levels of muscloskeletal injuries that they or their coworkers are experiencing. We have presented management with the Cellhouse workers health and safety issue. 

All parties agreed that the ergonomic improvements projects in the Zinc Cellhouse and Casting operations need adequate resources to ensure these projects are implemented in a timely fashion. The Worker Representatives and the company have recently developed a priority list of ergonomic projects and have held
