Clinical waste storage and sharps safety: rules and best practice

Updated 6 November 2026 · By the Clinical Waste Removal team

Short answer: Clinical waste should be stored in sealed, labelled bags or rigid containers inside lockable bins, in a secure area away from the public and separate from general waste, and collected before it builds up. Sharps containers must be assembled correctly, kept below the fill line and closed when full. After a needlestick injury, encourage bleeding, wash with soap and running water, cover the wound and get urgent medical advice the same day.

Why storage matters

Most clinical waste incidents happen before the waste is collected: bags left in corridors, bins unlocked behind a building, sharps containers overfilled, or waste piling up because collections are too infrequent. Under the Duty of Care, you must stop waste escaping from your control, and under health and safety law you must protect staff and others from harm.

Storage checklist

Bags no more than about three-quarters full and sealed with a swan-neck tie or tag
Bags and containers labelled with your name or site and the date
Waste moved to the store promptly, not left in treatment rooms or corridors
Rigid, lockable wheeled bins for bagged clinical waste
A dedicated, secure store or compound the public cannot reach
Clinical waste kept separate from general waste and recycling
Different streams kept apart, for example infectious and offensive
Store area clean, dry, well lit and protected from animals and pests
Spill kit available and staff know how to use it
Collections frequent enough that waste does not build up

Sharps container rules

Sharps containers should meet UN3291 and BS EN ISO 23907. Assemble them exactly as the manufacturer shows, and check the lid has clicked fully shut, because a poorly fitted lid can come off when the container is full. Write your details on the label when you start using the container.

Keep the container at a safe working height, ideally wall or trolley mounted
Take the container to the point of use, not the sharp to the container
Dispose of sharps straight away, without re-sheathing needles
Never fill above the fill line
Use the temporary closure between uses
Never put your hand inside or try to retrieve anything
When full, lock the final closure and date the label

The sharps regulations

The Health and Safety (Sharp Instruments in Healthcare) Regulations 2013 apply to healthcare employers and their contractors. They require employers to avoid unnecessary use of sharps, use safer sharps that include protection mechanisms where reasonably practicable, place secure containers close to where sharps are used, ban recapping of needles, and give staff training and information. Similar duties apply in other sectors through general health and safety law and COSHH.

What to do after a needlestick injury

Encourage the wound to bleed gently, without sucking it
Wash it thoroughly with soap and running water, without scrubbing
Dry and cover it with a waterproof dressing
Get urgent medical advice the same day, from occupational health, A&E or NHS 111
Report it to your manager and record it in the accident book
Keep details of the source if known, as treatment decisions may depend on it

Some sharps injuries must be reported under RIDDOR, for example where the source is known to carry a bloodborne virus or the person develops an infection as a result. Employers should check the HSE guidance for which cases need reporting.

Speed matters after a needlestick injury, because some preventive treatments work best when started within hours. Make sure every member of staff knows where to go for urgent advice, including out of hours, and display the steps near sharps containers and in the staff area. Afterwards, look at how the injury happened, such as an overfilled container, a needle left on a tray or re-sheathing, and change the process so it does not happen again.

Dealing with spills

Spills of blood, body fluids or leaking waste should be dealt with straight away by trained staff, following your infection control policy. A spill kit kept near treatment areas and the waste store means nobody has to improvise.

Put on disposable gloves and an apron, and eye protection if splashing is likely
Contain the spill with absorbent granules or paper towels from the kit
Disinfect using the product and contact time your policy specifies
Place all used materials in the correct clinical waste bag
Remove gloves and apron last and wash your hands thoroughly
Record the spill and restock the kit

If a waste bag splits or a container leaks in storage, repack the waste into a new bag or container inside another, rather than trying to tie off a damaged bag, and tell your contractor before collection.

How often to collect

Type of producer	Typical collection frequency
Busy GP surgery, nursing home or clinic	Weekly or fortnightly
Smaller surgery, dental practice or residential home	Fortnightly or monthly
Tattoo, aesthetics or beauty studio	Every one to three months for sharps
Low-volume practitioner	On request when containers are full

Frequency should be set so that waste never overflows and does not sit in storage longer than is safe and practical. Infectious waste in particular should not be kept for long periods, especially in warm weather.
