Determining the Right Number of First Aiders in the Workplace
The Importance of Adequate First Aid Cover
Having the correct number of trained first aiders is essential to ensure a prompt and effective response in the event of an emergency. The number of first aiders required depends on several key factors, including workforce size, risk level, and work environment.
HSE Guidelines for First Aid Provision
Low-Risk Workplaces (e.g., offices, shops, small businesses)
- Fewer than 25 employees – A designated appointed person is usually sufficient.
- 25 to 50 employees – At least one Emergency First Aid at Work (EFAW) trained first aider is required.
- More than 50 employees – At least one First Aid at Work (FAW) trained first aider per 100 employees.
Medium to High-Risk Workplaces (e.g., warehouses, factories, construction sites)
- Fewer than five employees – A designated appointed person is necessary.
- 5 to 50 employees – At least one EFAW or FAW trained first aider is required.
- More than 50 employees – One FAW trained first aider per 50 employees is recommended.
Very High-Risk Workplaces
- Heavy manufacturing, forestry, offshore, and chemical industries require at least one first aider for every 10 to 15 employees.
- Additional provisions such as trauma first aid training, Critical Injury Kits, and oxygen therapy may be needed.
Additional Considerations for First Aid Provision
- First aiders must be available across all shifts and working hours.
- Remote and lone workers must have access to portable first aid kits and emergency contact methods.
- Each separate site or location must have sufficient trained first aiders.
- Extra cover is necessary during peak times or when using temporary or seasonal staff.
Employers must ensure multiple staff members are trained to avoid gaps when first aiders are unavailable due to leave or illness. Maintaining robust first aid arrangements is critical for workplace safety and compliance with regulations.
