A serious bleed can turn an ordinary workday, sporting event or family outing into a life-threatening emergency within minutes. Knowing how to treat severe bleeding is not about doing everything perfectly. It is about recognising the urgency, calling for help early and taking clear action that gives a person the best possible chance until paramedics arrive.
For workplaces, this capability is part of genuine duty of care. A first aid kit on the wall is not enough if people are unsure who will call 000, where emergency equipment is kept or how to respond under pressure. A practised response protects people first, while also helping leaders manage the wider incident calmly and effectively.
Recognise when bleeding is severe
Bleeding needs urgent action when it is heavy, continuous or difficult to control. Blood that spurts or pulses from a wound may indicate an arterial bleed. A large volume of blood on clothing, the floor or surrounding surfaces is also a warning sign, even when the wound itself is not easy to see.
Treat the situation as life-threatening if blood is flowing quickly, soaking through dressings, pooling, or if the person becomes pale, sweaty, weak, confused or drowsy. These can be signs of shock, where the body is not getting enough circulating blood and oxygen.
Do not wait to see whether the bleeding settles. Severe bleeding can occur after machinery incidents, broken glass injuries, falls, vehicle crashes, sporting accidents or violence. It may also be hidden by clothing, particularly after a crush injury or a fall.
How to treat severe bleeding: act in the right order
Your first priority is safety. Check for immediate dangers such as moving vehicles, electrical hazards, machinery, violence, broken glass or fire. Use gloves from the first aid kit if available, but do not delay life-saving care while searching for personal protective equipment.
Call 000 as soon as possible, or direct a specific person to call. In a workplace, give clear instructions rather than asking generally for someone to help. For example: “You in the blue shirt, call 000 and come back to tell me what they say.” Ask another person to bring the first aid kit, trauma kit or automated external defibrillator if one is available.
Tell the emergency call taker where you are, what has happened, how severe the bleeding is and whether the person is conscious and breathing normally. Follow their instructions. If the incident occurs in a large site, arrange for someone to meet paramedics at the entrance and guide them to the casualty.
Apply firm, direct pressure
For most severe external bleeding, apply firm, steady pressure directly over the wound using a sterile dressing, clean cloth or trauma dressing. Use the heel of your hand and press continuously. Your role is not to inspect the wound repeatedly. It is to keep pressure on it.
If blood soaks through, add another dressing or cloth over the top and keep pressing. Do not remove the original dressing, as this can disturb any clotting that has started. Where possible, maintain pressure until paramedics take over.
If there is an object embedded in the wound, do not remove it. Apply pressure around the object and use bulky dressings to support it in place. Removing an embedded object may make bleeding much worse.
Use a tourniquet for life-threatening limb bleeding
A tourniquet is an essential tool for severe bleeding from an arm or leg when direct pressure alone is not controlling the bleed, or when the injury is clearly catastrophic. Commercial tourniquets are designed for this purpose and should be included in first aid arrangements where a risk assessment identifies a credible need, such as construction, manufacturing, remote work, security or high-risk sporting activities.
Place the tourniquet above the wound, between the wound and the torso. Keep it clear of joints. If the exact wound location is difficult to assess quickly, place it high on the injured arm or leg. Tighten it until the bleeding stops. This will be painful, but a tourniquet that is not tight enough will not control life-threatening bleeding.
Record the time it was applied and tell paramedics. Do not loosen, remove or periodically release the tourniquet. The person needs urgent hospital care.
Improvised tourniquets can be unreliable and may cause harm if applied incorrectly. The better workplace decision is to provide suitable commercial equipment where appropriate and ensure designated first aiders receive practical training in its use.
Pack deep wounds only when trained and equipped
Some severe wounds occur in areas where a tourniquet cannot be applied, such as the groin, armpit, shoulder or neck. For deep wounds in these areas, trained responders may use wound packing with haemostatic gauze or plain gauze, followed by firm direct pressure.
This is a practical skill that needs hands-on instruction. It is not simply placing a dressing over the top. Gauze is packed firmly into the wound cavity to reach the source of bleeding, then pressure is maintained. If your training does not cover wound packing, apply direct pressure and continue to follow the 000 operator’s instructions.
Never put fingers into a chest or abdominal wound. Cover the injury as directed by emergency services and focus on keeping the person still, supported and monitored.
Manage shock while help is on the way
A person with severe bleeding can deteriorate rapidly, even after bleeding appears controlled. Keep them as still and comfortable as possible. If there is no suspected spinal, pelvic, leg or head injury, and they can tolerate it, lay them down. Keep them warm with a blanket, jacket or other covering.
Reassure them in a calm voice. Simple statements help: tell them help is coming, ask them to stay still and let them know you are with them. Do not give food, drink, alcohol or medication unless instructed by qualified emergency personnel.
Continue to observe their breathing and level of responsiveness. If they become unresponsive but are breathing normally, place them in the recovery position if it is safe to do so without worsening injuries. If they are not breathing normally, start CPR and use an AED as soon as available.
What workplace teams should prepare before an incident
The quality of a bleeding response is usually determined well before someone is injured. Emergency equipment must be easy to locate, clearly marked, maintained and appropriate for the hazards of the site. A low-risk office may need different resources from a warehouse, childcare setting, kitchen, construction site or community venue.
Workplace leaders should consider whether first aid kits include adequate trauma dressings, gloves, shears, thermal blankets and, where justified by risk, commercial tourniquets and haemostatic gauze. Equipment alone is not the answer. Staff need to know what it is for, who is authorised to use it and how to access it without delay.
Clear roles matter as well. During a serious incident, someone needs to call 000, someone may need to meet emergency services, and a first aider may need uninterrupted space to provide care. Supervisors should also know how to manage bystanders, preserve privacy and begin incident reporting only after the person’s immediate needs are addressed.
Practical first aid training gives teams the chance to handle dressings, apply pressure and make decisions in realistic scenarios. That experience can replace hesitation with purposeful action when seconds count.
Common mistakes to avoid
The most damaging error is delaying action because the injury looks confronting. Do not wait for a manager, a family member or a more confident colleague before applying pressure and calling 000. Severe bleeding is an emergency, not an incident to monitor from a distance.
Avoid repeatedly lifting dressings to check the wound, cleaning a heavily bleeding injury before controlling it, or moving the person unnecessarily. Do not remove embedded objects. Do not leave the casualty alone unless you must do so to call for help and no one else is available.
There is also a balance between protecting yourself and responding quickly. Gloves reduce exposure to blood, but if gloves are not immediately available, use a barrier such as a clean cloth or ask the person, if conscious, to apply pressure while you obtain supplies. The priority remains controlling the bleed and activating emergency help.
A capable response to severe bleeding starts with one decision: act early, apply pressure and get emergency help moving. When people have the right equipment, clear procedures and practical training, they are better prepared to protect a colleague, customer, child or loved one when it matters most.
Be ready before the emergency happens. Confidence is built through preparation, then proven through calm action.
