Medical instruments and products containing mercury (Hg) are still widely used in health care facilities. These are mostly thermometers and sphygmomanometers. Breakage, inadequate maintenance and disposal of such instruments can expose workers and the public to this toxic substance. Mercury can easily enter the body if its vapor is inhaled. If the environment is polluted by this substance, it may also be transformed into an organic form and contaminated fish or other foods may be ingested. Long-term exposure to mercury can permanently damage the brain, kidneys, and developing fetuses. This guide has been designed for health care facilities personnel involved in safety committees and risk management activities. It provides information to prevent exposure to mercury vapors, mainly by identifying safe substitutes for mercury in medical instruments and other products. This guide also recommends preparedness and response activities in relation with accidents involving metallic mercury.
