The dangers of mercury

Mercury is a unique metal that is liquid at room temperature. The shiny, silvery metal is highly toxic to humans, ecosystems, and wildlife. Elemental mercury evaporates very slowly and produces a toxic vapour. When inhaled, you can suffer from severe health problems such as kidney damage and neurological disorders including tremors and cognitive dysfunctions.

Although this form of mercury (elemental mercury) is the most dangerous, all kinds of mercury are toxic, such as methylmercury, which you can consume through food like fish.

You should always avoid direct contact with any form of mercury, particularly with elemental mercury, and if you suspect a spillage has happened, get professional help immediately – don't try fixing it yourself. It is also recommended you regularly check for household items that might contain this hazardous element.

What household products contain mercury?

Mercury used to be used in a variety of common household items. However, due to the dangers associated with potential spills, it is now illegal to manufacture or import products that contain mercury in Great Britain. Most household products that contain mercury are therefore antiques. Here are some of the most common household products that contain mercury. 

Thermometers and barometers

Most domestic mercury spills are caused by broken traditional thermometers and barometers. The silvery liquid inside these instruments allows them to react to temperature and pressure changes accurately. Although newer digital models have largely replaced these older devices, they may still lurk in medicine cabinets or hang on walls as functional heirlooms.

CFL bulbs

Compact fluorescent lamps (CFLs) contain a very small amount of mercury vapour which is crucial for producing light when electricity passes through them. You must pay special attention when disposing of burnt-out CFL bulbs; don't just chuck them into your regular rubbish bin.

Electrical switches and relays

Older types of electrical switches - like those designed for use in safety applications like fire alarms - sometimes utilise small amounts of mercury to allow them function effectively under varying temperatures. 

How to dispose of mercury safely

If you find yourself with mercury or mercury-containing products that need disposing of, it's crucial to handle them correctly. Mercury is highly toxic and poses a significant environmental threat if not dealt with properly.

Disposal protocols for households

Disposing of mercury thermometers and other mercury-containing products is usually quite straightforward. Your local council will have dedicated services for disposing of hazardous wastes though arrangements can vary across different councils. 

If mercury spills in your home, bring in professionals immediately to clean up the spill and dispose of the hazardous waste. Don't attempt to clean it up yourself, nor should you throw mercury in household rubbish or put it down the drain. Professional cleaners will have the training and experience to eliminate all traces of the mercury from your home, and will be well-versed in disposal regulations. 

ICE Cleaning's technicians can even detect the mercury vapour levels in your home and flush them out of the property. It is recommended you always bring in professionals so they can take care of the dangerous situation for you.

Protocols for businesses

For businesses dealing with larger quantities or industrial use of mercury, compliance gets more technical but no less crucial. They need to classify their waste correctly using European Waste Catalogue codes as classification dictates subsequent handling processes.

Apart from adhering strictly to the hazardous waste regulations - which include getting premises registered as producing hazardous waste - businesses should also maintain records for at least two years post-disposal.

Contact your local council for advice

Your local council can be a wealth of information when you are looking to get rid of any dangerous substances like mercury. They'll guide you through their specific disposal processes and let you know about dedicated collection days or disposal facilities near you.

Bear in mind that different councils might have varied protocols based on available resources and regulations within each region, so checking with them directly ensures compliance while safeguarding community health and ecosystems.
