Renovation is usually the reason that the equipment is replaced.
Even if mercury use in newly manufactured equipment is discontinued, the recycling or disposal of used equipment will require an awareness of the mercury content for a long time to come. Manufacturers have not eliminated mercury in all electrical equipment due to cost considerations. However, because of an awareness of mercury problems, manufacturers are increasingly making alternatives available. Ask your vendor to assist the hospital in selecting mercury-free products. If the hospital is preparing used electrical equipment for recycling or disposal and there is a question about the mercury content, obtain this information from the manufacturers.
