Regulation 3 of the Health and Safety (First Aid) Regulations 1981 states: 'An employer shall provide, or ensure that there are provided, such equipment and facilities as are adequate and appropriate in the circimstances for enabling first-aid to be rendered to his employees if they are injured or become ill at work'.

The level of provision will depend on the level of risk and the numbers of employees in the workplace. Guidance states that low risk workplaces like shops or offices should have qualified first-aiders when the number of staff is greater than 50. Otherwise there should be an "appointed person" who has responsibility for keeping the first aid box and calling an ambulance if it is needed. Download our Guide to First-Aid for more information
