If your business works with machinery, power tools or sharp equipment, a standard first aid kit may not be enough. A bleed control kit for the workplace is designed to treat catastrophic, life-threatening bleeding in the minutes before an ambulance arrives, and UK health and safety guidance increasingly expects businesses to consider one as part of a proper risk assessment. Severe bleeding can become fatal within two to three minutes, often faster than the fastest ambulance response, which is why more employers in construction, manufacturing, agriculture and warehousing are adding bleed control provision alongside their standard BS 8599-1 kits.
This guide explains what a bleed control kit is, whether UK law requires one, and how to work out if your workplace needs one.
What Is a Bleed Control Kit?
A bleed control kit, also called a catastrophic bleeding kit or trauma kit, is a specialist first aid supply designed to stop severe external bleeding that a standard kit cannot manage. Where an everyday workplace first aid kit is built around plasters, dressings and bandages for cuts, sprains and minor burns, a bleed control kit contains equipment for a very different category of injury: bleeding severe enough to be life-threatening within minutes.
Typical bleed control kits include a commercially manufactured tourniquet, haemostatic (clotting) dressings, trauma or pressure dressings, wound packing gauze and trauma shears. Some are sold as standalone add-ons, others as BS 8599-1 critical injury kits, designed to sit alongside your existing first aid provision rather than replace it.
Bleed Control Kit vs Standard First Aid Kit: What's the Difference?
The short answer: a standard first aid kit treats minor injuries, while a bleed control kit treats catastrophic ones. HSE and BS 8599-1 compliant workplace kits are built for cuts, grazes, minor burns and sprains, not for bleeding severe enough to be life-threatening. They typically contain no tourniquet and no haemostatic dressings. A bleed control kit exists specifically to fill that gap, providing the equipment recommended by the European Resuscitation Council and referenced in HSE's own first aid guidance for managing life-threatening bleeding until emergency services arrive.
Is a Bleed Control Kit a Legal Requirement in UK Workplaces?
There is no UK law that names bleed control kits specifically, but the legal duty behind them is well established. Under the Health and Safety at Work etc. Act 1974, employers must ensure, so far as is reasonably practicable, the health and safety of their employees. The Health and Safety (First-Aid) Regulations 1981 build on this, requiring "adequate and appropriate" first aid equipment, facilities and personnel based on a proper first aid needs assessment, not a fixed, one-size-fits-all list.
HSE's guidance on the regulations (L74) has been updated to address this directly. Its needs assessment checklist now asks employers to consider the risk of life-threatening bleeding when reviewing their accident record, and its section on additional first aid materials and equipment references tourniquets and haemostatic dressings by name. Appendix 4 goes further, noting that employers in hospitality, events and other higher-risk sectors should consider additional training in managing life-threatening bleeding, including wound packing.
The British Standard for workplace first aid kits, BS 8599-1:2019+A1:2026, reinforces this. It sets out a specific critical injury kit for workplaces involving dangerous machinery, sharp instruments, cutting equipment, power tools, construction, agriculture or forestry, containing trauma dressings, haemostatic dressings and a tourniquet, in line with European Resuscitation Council recommendations.
In short, there is no blanket legal requirement, but if your first aid needs assessment identifies a risk of severe bleeding, providing only a standard kit is unlikely to meet your "adequate and appropriate" duty under the 1981 Regulations.
Does Your Workplace Need a Bleed Control Kit?
Whether you need one comes down to your first aid needs assessment, not a generic checklist. HSE guidance asks employers to weigh up the nature of the work, the hazards present and the workplace's accident history when deciding what provision is "adequate and appropriate". For many offices and low-risk premises, a standard BS 8599-1 kit will remain sufficient. For others, the picture is different.
HSE's most recent RIDDOR figures, for 2024/25, recorded 59,219 non-fatal employee injuries and 124 worker fatalities, with amputations and serious crush injuries among the "specified injuries" employers are legally required to report. These are exactly the kinds of injury a bleed control kit is designed to help with in the critical minutes before help arrives.
High-Risk Sectors and Environments
A bleed control kit is worth considering if your workplace involves any of the following:
- Machinery, power tools or cutting equipment, including workshops, manufacturing and food processing
- Construction, agriculture or forestry work, where BS 8599-1 specifically recommends a critical injury kit
- Vehicles, transport or logistics operations
- Premises with significant public footfall, where the Terrorism (Protection of Premises) Act 2025 (Martyn's Law) may also become relevant once it comes into force
- Remote sites or locations with longer ambulance response times
If any of these apply to your business, it is worth documenting the decision, or the reasoning behind not providing a kit, as part of your written first aid needs assessment.
What's Inside a Bleed Control Kit?
Contents vary between suppliers, but a typical bleed control kit for the workplace includes:
- A commercially manufactured windlass tourniquet
- Haemostatic (clotting) gauze or dressings
- A trauma or pressure dressing, sometimes known as an emergency bandage
- Wound packing gauze
- Trauma shears, for cutting away clothing quickly
- Nitrile gloves and clear, illustrated instructions for use
Look for tourniquets and haemostatic dressings that are CE-marked or UKCA-certified for medical use, and check sterile components against their shelf life. Unlike most of a standard first aid kit, these items are single-use and need replacing immediately after any real deployment, or once they reach their expiry date.
Who Can Use a Bleed Control Kit?
Direct pressure remains the first response to any severe bleed, and this is where every trained first aider should start. Resuscitation Council UK and the European Resuscitation Council's first aid guidelines are clear that tourniquets and haemostatic dressings should only be used when direct pressure alone fails to control life-threatening bleeding, and ideally by someone trained in their use.
Standard Emergency First Aid at Work (EFAW) and First Aid at Work (FAW) courses already cover life-threatening bleeding as a topic, but the specific use of tourniquets and haemostatic dressings is usually an additional module. The First Aid Quality Partnership recommends that training providers include this as extra content where an employer's risk assessment identifies the need, rather than assuming it is already covered. It is worth confirming with your training provider that catastrophic bleeding and tourniquet use are included, or can be added, before you invest in a kit.
Where to Keep Your Bleed Control Kit
Bleed control kits work best when they are as visible and accessible as a defibrillator. Wall-mounted in a clearly signed cabinet, near high-risk work areas or alongside an AED, is the usual approach. Avoid locking the kit away where staff would need to search for a key, since the time it takes to reach someone with a life-threatening bleed is often shorter than the average ambulance response.
If your premises regularly host 200 or more people at once, it is also worth keeping an eye on the developing requirements of Martyn's Law. The Home Office published statutory guidance on 15 April 2026, with commencement now expected in spring 2027, and enhanced first aid and trauma provision is one of the practical measures many venues are already reviewing ahead of that date.
Practical Takeaways
- Bleed control kits are not a blanket legal requirement, but your first aid needs assessment may show you need one
- BS 8599-1:2019+A1:2026 recommends a critical injury kit for high-risk sectors including construction, agriculture and manufacturing
- A standard workplace first aid kit is not designed to treat life-threatening bleeding
- Confirm your first aiders have training in tourniquet and haemostatic dressing use before relying on a kit
- Site the kit somewhere visible and accessible, and review it as part of your regular first aid checks
