C
= Safety Factor
The value for 𝐻𝐻𝐻𝐻 is the length of the suspended worker after a fall and includes factors like the height of the person and harness stretch, to account for these variables this is set to 2.00 m. Using the value for 𝐻𝐻𝐻𝐻 (2.00 𝑚𝑚 ) , the maximum allowed values for 𝐿𝐿𝐿𝐿 (2.00 𝑚𝑚 ) & 𝐷𝐷𝐷𝐷 (1.75 𝑚𝑚 ), and the minimum allowed value for 𝐶𝐶 (1.00 𝑚𝑚 ), we get, 𝑅𝑅𝑅𝑅 = 𝐿𝐿𝐿𝐿 + 𝐷𝐷𝐷𝐷 + 𝐻𝐻𝐻𝐻 + 𝐶𝐶 and, 𝑅𝑅𝑅𝑅 =2.00 𝑚𝑚 +1.75 𝑚𝑚 +2.00 𝑚𝑚 +1.00 𝑚𝑚 , therefore , 𝑅𝑅𝑅𝑅 =6.75 𝑚𝑚 . Therefore, the GWO recommends that the anchor points used during the evacuation exercises are placed a minimum of 6.75m above the ground or any structure which a person may come into contact with, in the event of a fall.
