ISO 13849: Frequency and/or exposure to hazard - how to decide F1/F2?
In ISO 13849-1, you need to choose F1 if:
- A person is exposed to the hazard more frequently than once every 15 minutes and/or
- The total exposure time exceeds 1/20 of the machine’s operating time (equal to 24 minutes per 8-hour shift).
Otherwise, choose F2.
