HSE Guidelines - Minimum Number of Appointed Persons and First Aiders.

Click here for the HSE´s free interactive assessment tool to help you decide what level of first aid provision you need http://www.hse.gov.uk/firstaid/assessmenttool.htm

NB: An Appointed Person can be considered adequate for low risk environments with a small number of personnel, after completing a 4 - 6 hour course. The HSE considers a person to be a ´First Aider´ when they have successfully completed a 3 day course (or *2 day refresher* course as required) and the HSE considers a person to be an ´Emergency First Aider´ when they have completed a HSE Compliant Emergency First Aid at Work Course (1 day).

* The 2 day refresher courses need to be completed within three years of previous certification.*

It is the responsibility of each Organisation to perform their own Risk Assessment to decide how many Appointed Persons / First Aiders they need.
