Safe Chemical Waste Disposal for Healthcare & Labs

Those working in healthcare facilities and laboratories come into contact with an array of chemicals. With the right precautions and disposal protocols in place, all chemical waste can be handled safely.

Whether you’re dealing with chemical disposal in a hospital, clinic, lab, or pharmacy, our guide is here to offer insights into how to manage the process in a safe and compliant manner.

What forms of chemical waste need careful disposal?

From pharmaceuticals to solvents and cleaning products, a wide range of chemicals are necessary in the healthcare industry. While these chemicals are used to keep spaces hygienic, carry out tests or research, and provide treatments, they can also pose health hazards if handled incorrectly.

Proper chemical disposal after use is vital for protecting those handling them, and also for preventing them from damaging the environment. Harmful chemicals can leach into the ground, contaminate water supplies, and harm wildlife.

The chemicals used in healthcare settings and laboratories vary depending on the type of facility, but here are a few you may come across:

Antibacterial hand sanitisers
Cleaning products containing bleach, ammonia, and similar ingredients
Solvents such as ethanol, methanol, and acetone
Formaldehyde
Cytotoxic drugs for cancer treatment
Mercury (from dental amalgam or broken thermometers)
X-ray and photographic chemicals
Batteries containing heavy metals
Anaesthetic gases

It’s important to note that any equipment that comes into contact with these chemicals (such as gloves, syringes, or tubing), will also need to be disposed of with care.

Which regulations govern chemical waste disposal in healthcare?

Since proper handling of chemical waste is so important in healthcare, there are several key legislations that must be followed.

The Environmental Protection Act 1990: This law states that any facility that produces hazardous waste must classify, manage, document, and transport it for disposal safely. Failing to do so can lead to fines and prosecution.
The Hazardous Waste Regulations 2005 (England and Wales): These regulations relate specifically to hazardous waste and require you to classify and segregate waste, store it securely, and ensure it is carefully tracked. (In Scotland, a separate Special Waste law is in place).
The Health and Safety at Work Act 1974: Under this guidance, all employers have a duty of care to keep their employees safe. They must carry out risk assessments and ensure teams have the systems and equipment they need to handle and dispose of chemical waste safely.
Control of Substances Hazardous to Health (COSHH): COSHH regulations require risk assessments where substances (including chemicals) could be harmful to health. It also covers safe handling of chemicals and other harmful materials.

How to dispose of healthcare chemicals safely

Safe chemical disposal not only keeps your healthcare facility compliant with the legislation we’ve discussed, but also protects staff, patients, and visitors.

1. Segregate waste using colour-coordinated containers

Safe chemical disposal starts with knowing where to put different forms of waste. Use clearly labelled, colour-coordinated bins, bags, and containers so that it’s immediately obvious what each one contains.

At phs, you’ll find a range of high-quality solutions for storing clinical waste, including:

Purple waste containers for cytotoxic and cytostatic waste
Blue bins for pharmaceutical waste
Orange sharps bins for highly infectious waste (contaminated with blood and bodily fluids but no pharmaceuticals)
Yellow sharps bins for clinical waste (contaminated with medicinal waste)
Yellow and black striped (tiger) bags for offensive waste (such as nappies and sanitary waste)
White containers for dental amalgam and gypsum
Red bags for anatomical waste
Black bags for non-hazardous general waste

2. Provide staff training

It’s important to make sure all team members have a strong understanding of how to segregate waste streams. With this in mind, adequate training on safe chemical waste disposal should always be provided. It’s also helpful to display posters with key information around your facility.

3. Partner with a licensed chemical disposal service provider

To remain compliant with health and safety guidance, your chemical waste must only be collected and transported by a licensed service provider. They will have the training, experience, and equipment to handle chemical waste without posing risks to the environment and public health.

They will also be able to provide you with a waste transfer notice so you have a written record of your compliant chemical disposal method. Licensed handlers will also take the waste to a suitable facility, depending on whether it needs to be incinerated or disposed of in another way.
