What Is Mercury & Why Is It Dangerous?

Mercury is a naturally occurring element and is one of the most toxic heavy metals in the world. Due to its ability to dissolve other metals and alter their properties, as well as having the lowest freezing and boiling points of any metal, mercury has been a desirable asset over time. Traditionally, the material has been used in many everyday items such as batteries, thermometers, barometers, fluorescent lights and manometers, as well as other devices. It was not until later, however, that the high toxicity of the substance was discovered, when mercury was already present in a large number of consumer products such as medicinal treatments and industrial processes.

Mercury can enter the human body through inhalation, ingestion or through open cuts and wounds and can be found in many everyday materials. If you are responsible for the health and safety welfare of a building and its occupants, it is crucial that you contact the experts to conduct a mercury test and any subsequent remedial work on your site to ensure individuals are protected from possible life-threatening exposure.
