Two workers are operating from a personnel work platform on a telehandler. They are both wearing full body harnesses and using self-retracting lifelines (SRLs) connected to designated anchor points on the platform. If one worker weighs 90 kg and the other weighs 110 kg, what is the minimum required strength for each anchor point, according to CSA Z259.13 and provincial regulations for fall arrest systems with SRLs?

Question: Two workers are operating from a personnel work platform on a telehandler. They are both wearing full body harnesses and using self-retracting lifelines (SRLs) connected to designated anchor points on the platform. If one worker weighs 90 kg and the other weighs 110 kg, what is the minimum required strength for each anchor point, according to CSA Z259.13 and provincial regulations for fall arrest systems with SRLs?

Answer options: ✅ 16 kN (3,600 lbf)

• 8 kN (1,800 lbf)
• 22 kN (5,000 lbf)
• 4.5 kN (1,000 lbf)

Correct answer: 16 kN (3,600 lbf)

Explanation: According to CSA Z259.13 and provincial occupational health and safety regulations, a fall arrest anchor point must be capable of withstanding a force of 16 kN (3,600 lbf) per worker attached, or a force equal to four times the maximum arresting force in the system. Given two workers, each anchor point must meet this minimum specification. 8 kN and 4.5 kN are insufficient, and 22kN is typically for systems that include impact forces of a larger system or specific structural elements, not usually for individual anchorage points in this context.
