First Aid Teams

How many first aid personnel do I need?

The Health and Safety (First Aid) Regulations 1981 require companies to provide an adequate number of first aid personnel based on an assessment of risk and need. In assessing need, employers need to consider:

  • workplace hazards and risks;
  • the size of the organisation;
  • the organisation's history of accidents;
  • the nature and distribution of the workforce;
  • the remoteness of the site from emergency medical services;
  • the needs of travelling, remote and lone workers;
  • employees working on shared or multi-occupied sites;
  • annual leave and other absences of first aiders and appointed persons.

Whilst the regulations do not give specific personnel numbers, the guidance does give suggested numbers of first aid personnel. See the table below.


Category of risk Numbers employed at any location Suggested number of first-aid personnel
Lower risk (eg shops, offices, libraries) Fewer than 50 At least one appointed person
50 - 100 At least one first aider
More than 100 One additional first aider every 100 employed
Medium risk (eg light engineering and assembly work, food processing, warehousing) Fewer than 20 At least one appointed person
20-100 At least one first aider for every 50 employed (or part thereof)
More than 100 One additional first aider every 100 employed
Higher risk (eg construction, slaughterhouses, chemical manufacture, extensive work with dangerous machinery or sharp instruments) Fewer than 5 At least one appointed person
5-50 At least one first aider
More than 50 One additional first aider every 50 employed
These figures are for guidance only and are neither definitive nor are they a legal requirement. It is your company's obligation to assess your first aid needs in the light of your particular circumstances.
