The Problem
Mercury is a highly toxic substance that poses serious health risks, including neurological issues such as memory loss, mood swings, and anxiety, as well as physical symptoms like muscle weakness and breathing difficulties. Even small spills can release harmful vapours that linger if not properly cleaned, making professional intervention essential.
At a residential property in Altrincham, a barometer (a device used to measure air pressure) was accidentally knocked over in the garage, releasing mercury onto the concrete floor, a hostess trolley, and nearby clothing. The fire brigade attended to address the immediate risk and advised the homeowner to seek specialist mercury cleaning services.
UK Mercury Spill Risks:
- Health Impact: According to the UK Health and Safety Executive (HSE), mercury exposure can lead to irreversible nervous system damage. Even a few drops of spilled mercury can release toxic vapours that exceed safe exposure limits.
- Common Sources: Older household items, such as thermometers and barometers, contain mercury, posing a risk if broken. Studies show that broken thermometers or barometers can release enough mercury to contaminate indoor air for months if not cleaned properly.
- Safety Standards: The World Health Organization (WHO) sets strict exposure limits to prevent long-term health effects. Expert mercury cleaning reduces health risks and ensures compliance with HSE and WHO safety guidelines.
Recognising the dangers, the homeowner contacted our specialist team for a full mercury clean-up.
The Solution
Upon arrival, our trained technicians conducted a thorough assessment of the contaminated area, identifying mercury deposits on the garage floor, the hostess trolley, and bagged-up clothing.
Step 1: Mercury Collection & Containment
- Used a precision syringe to collect visible mercury droplets.
- Deposited collected mercury into a secure spill kit container for safe disposal.
Step 2: Surface Cleaning & Decontamination
- Utilised specialist ‘push cards’ to gather residual mercury into manageable areas.
- Applied amalgamating powder, designed to bind with mercury and prevent vapour release.
- Carefully checked grooves, floor joints, and any potential crevices for contamination.
Step 3: Neutralisation & Safe Disposal
- Sprayed the treated area with cold water to activate the amalgamating powder.
- Used dampened sponges to wipe up the residue, ensuring complete mercury removal.
- Sealed all contaminated materials in a dedicated spill container, marked with hazardous waste labels for secure offsite disposal.
Step 4: Air Quality Testing & Verification
- Used a Mercury Vapour Indicator (MVI) to detect any lingering mercury vapours.
- If traces had been found, the cleaning process would have been repeated.
The Result
Our final readings confirmed that the affected areas met safe and acceptable levels as defined by WHO standards. With all hazardous material safely removed and properly disposed of, the homeowner could be confident that their property was free from mercury exposure.
Key Outcomes:
- Complete Decontamination – All mercury removed, and surfaces restored to a safe condition.
- Air Quality Assurance – No detectable mercury vapours remaining.
- Safe Disposal – All contaminated waste sealed and processed in accordance with UK hazardous material regulations.
