Can Your Workplace Handle Two Casualties at Once?

Your first aider knows where the kit is and your emergency contact details are displayed. But what happens if two people need help at the same time?

A workplace incident may affect more than one person. A collision, equipment failure or other emergency can create competing demands for help, equipment and communication.

A two-casualty exercise is a practical way to test your workplace first aid arrangements. It can reveal gaps that are less obvious when your planning assumes one casualty and one available first aider.

ProTrainings Europe offers workplace first aid courses and Major Incident Trauma training to support organisations with different risks and training needs.

Start with your actual workplace risks

Choose a scenario that reflects your workplace. A small office, construction site, warehouse and hospitality venue will have different activities, hazards and staffing arrangements.

Use your first aid needs assessment to review personnel, equipment and facilities. Consider work patterns, separate areas, staff absence and how emergency services would reach your site.

Two casualties do not automatically mean a major incident or a fixed requirement for two first aiders. The purpose of the exercise is to explore whether your arrangements work for a plausible situation in your setting.

A simple scenario to discuss with your team

Imagine that an incident in a work area has injured two colleagues. One has significant bleeding from a leg injury. The other has an injured arm and is distressed. Your usual first aider is available, but another trained colleague is working elsewhere on site.

Run this as a planned discussion first. Ask how staff would raise the alarm, assess scene safety, summon help and bring equipment. Any practical treatment exercise should be led by a suitably qualified instructor using safe simulation.

Avoid creating real hazards. Do not use moving machinery, sharp objects or unstable equipment to make a scenario feel realistic.

1. Check how people would make the scene safe

Before approaching casualties, responders need to consider hazards that could injure them or others. Your exercise should explore who can stop work, restrict access or arrange isolation of equipment through the appropriate site procedures.

Ask:

• How would staff raise the alarm?
• Who would stop nearby activity if it was safe to do so?
• How would others be kept away from hazards?
• Would responders know when it was unsafe to approach?

Do not expect first aiders to undertake hazardous rescue tasks beyond their training or role.

2. Review how additional help would be summoned

A first aider caring for one person may need someone else to call for emergency help, collect equipment or locate another trained colleague.

Check whether your internal alert system works across the building, outdoor areas and different shifts. A name on a noticeboard is less useful if nobody knows how to contact that person.

Give helpers clear tasks and ask them to confirm completion. Responsibilities should remain flexible if fewer people are available.

3. Practise communicating with emergency services

Discuss what information the caller would provide in a real emergency: the exact location, what has happened, known hazards, the number of casualties and their apparent conditions.

Make sure the caller can receive updates from the people helping the casualties and follow the emergency call handler’s instructions. Identify who would meet responders and guide them to the scene.

Do not call 999 during a drill. Use a simulated conversation and check that staff know the site address, postcode and appropriate entrance.

4. Check whether equipment can reach both casualties

Review the location and contents of your first aid kits against your assessed needs. Consider whether equipment would be accessible if one area was blocked or the nearest kit was already in use.

• Are kits easy to find and retrieve?
• Are supplies complete, intact and in date where applicable?
• Is appropriate protective equipment available?
• Can staff access any specialist equipment provided?
• Do people know who arranges replenishment after use?

Explore the ProTrainings first aid equipment store if your review identifies missing supplies. Where your assessment identifies a need for specialist bleeding equipment, browse our bleed control kits and equipment .

Additional equipment should be accompanied by relevant training and maintenance arrangements. Buying a specialist kit alone does not resolve a gap in preparedness.

5. Match training to your workplace needs

First aiders need the knowledge and practical skills appropriate to their role. Review whether your existing qualifications cover the risks identified in your workplace.

Start with our workplace first aid course range and speak to ProTrainings about suitable classroom or blended options. A blended workplace qualification includes required practical training and assessment; its online part alone does not complete the qualification.

For workplaces with relevant bleeding risks, explore Haemorrhage Control and the Use of Haemostatic Gauze training .

Organisations seeking broader learning about multiple casualty incidents can also explore Major Incident Trauma Level 3 . The course covers topics including scene safety, casualty prioritisation and trauma response. Discuss its suitability alongside your existing workplace first aid provision.

6. Use realistic practice without using live supplies

A qualified instructor can help your team practise communication, equipment retrieval and relevant first aid skills in a controlled setting.

Use dedicated training equipment and keep emergency supplies available. Do not open sterile dressings from the live kit for demonstrations or apply treatment devices to volunteers in ways that could cause injury.

For practical bleeding scenarios, ProTrainings supplies TrueClot wound simulation equipment . Follow the trainer’s instructions and use an appropriate area for simulated blood and cleaning.

7. Turn the debrief into an improvement plan

After the exercise, ask participants what helped and what caused confusion. Focus on improving the arrangements rather than blaming individuals.

Record each improvement, assign responsibility and set a completion date. Repeat the exercise once changes are in place, and review whether your first aid needs assessment should be updated.

Your multiple casualty preparedness checklist

• Choose a plausible scenario based on workplace risks.
• Check scene safety and internal alarm arrangements.
• Confirm how additional help would be summoned.
• Review equipment access and availability.
• Practise communicating the location and casualty information.
• Consider different shifts and staff absence.
• Identify relevant training needs.
• Complete and test the agreed improvements.

Strengthen your workplace response with ProTrainings

A short exercise can show how well your plans work when more than one person needs help. Use the findings to improve staffing, communication, equipment and training.
