anchor points
The height of the anchor point shall ensure that in the event of a fall there will be enough space below the anchor point to allow the shock absorber in a fixed length fall arrest lanyard to fully deploy while preventing the person who is falling from coming into contact with the ground or structure below the anchor point
Note
The GWO recommends an anchor point height of 6.75m for the evacuation exercises
The recommended height is based upon the following formula, 𝑅𝑅𝑅𝑅 = 𝐿𝐿𝐿𝐿 + 𝐷𝐷𝐷𝐷 + 𝐻𝐻𝐻𝐻 + 𝐶𝐶 , Where:
RD
=
required fall distance clearance (minimum anchor point height)
LL
=
length of lanyard
DD
=
deceleration distance (fall distance)
HH
=
height of suspended worker
C
=
safety factor
The value for HH is the length of the suspended worker after a fall includes factors like the height of the person and harness stretch, to account for these variables this is set to 2.00m. Using the value for HH (2.00m), the maximum allowed values for LL (2.00m) & DD (1.75m), and the minimum allowed value C (1.00 m), gives , 𝑅𝑅𝑅𝑅 = 𝐿𝐿𝐿𝐿 + 𝐷𝐷𝐷𝐷 + 𝐻𝐻𝐻𝐻 + 𝐶𝐶 And, 𝑅𝑅𝑅𝑅 =2.00 𝑚𝑚 +1.75 𝑚𝑚 +2.00 𝑚𝑚 +1.00 𝑚𝑚 , Therefore, 𝑅𝑅𝑅𝑅 =6.75m
