Saying No To Mercury
Virtually eliminating mercury from its facilities was the best way for
Park Nicollet Health Services to avoid employee, patient and
environmental exposure to this neurotoxin. Avoiding exposure to mercury
helps Park Nicollet further its mission to support health and healing.
To accomplish mercury elimination by 2005, Park Nicollet educated
employees about mercury hazards and using alternative, mercury-free
products. On track for 2005, it has eliminated 75 percent of the
mercury from its facilities.

Businesses that recycle used products containing elemental mercury
(such as thermometers, switches, and fluorescent bulbs) are exempt from
most hazardous waste regulations. However, mercury compounds and waste
contaminated with mercury (for example, spill skits) must be handled
according to the full hazardous waste regulations.
