Table O.2.1 gives the Beaufort wind force scale (generally referred to as the Beaufort O.2.1.10 scale), which is an empirical measure that relates wind speed to observed conditions at sea or on land. In fact, the Beaufort wind force scale is a measure of wind speed and not of force in the scientific sense. The scale is given up to Force 12. Higher forces exist but are considered irrelevant for this annex.Observed conditions can be very useful in judging wind speed if there is no anemometer O.2.1.11 available. The wind speeds in the table are given in kilometres per hour (km/h); miles per hour (mph); knots and metres per second (m/s). Table O.2.2 gives conversion factors for these wind speed© IRATA International Annex O Page 6 of 45 2017-Aug-01IRATA International code of practice for industrial rope access Part 3 of 5: Informative annexes: Annex O: Protecting rope access technicians against environmental conditions
