Mercury Remediation

When mercury is exposed or spilled, rapidly closing off the affected area and emergency cleanup are vital. Ventilation is a concern as free mercury will readily vaporize and continue to do so until the situation is under control. Distance is key. Proper handling and remediation are a must to ensure no trace is left behind. A&O Contracting is more than ready.

What's Mercury

It’s a silvery-white metal that is in liquid form at room temperature. It’s used in fluorescent bulbs, thermometers, older electrical switches, and medical and scientific equipment. When a spill occurs it can raise serious health concerns.


Mercury was widely found in plumbing systems in older laboratory facilities. They were poured into the drain and often thought to be completely gone.

During repairs or demolition, spills occur in these older facilities due to the mercury remaining in the drainage system and spilling on the floor when opened up.

Methods Of Cleaning Up Mercury Spills

Amalgamation or insolubilization is both methods used to turn mercury into a non-vaporizing form. Then it’s cleaned from there.

Insolubilization requires mercury to be mixed with sulfide and amalgamation mixes mercury with one or more metals so it becomes solid and can be disposed of easier.
