Which of these choices should be observed when climbing a tower using a safety harness?
- A.Always hold on to the tower with one hand
- B.Confirm that the harness is rated for the weight of the climber and that it is within its allowable service life (correct answer)
- C.Ensure that all heavy tools are securely fastened to the harness
- D.All these choices are correct
WhyWhen climbing a tower using a safety harness, confirm that the harness is rated for the weight of the climber and is within its allowable service life. A safety harness only protects the climber if it's actually rated for their weight and hasn't exceeded its manufacturer-specified service life, so confirming both of those before climbing is essential, answer B. Relying on one hand to hold the tower defeats the purpose of using a harness at all, and heavy tools should be carried on a separate tool line or bucket rather than fastened directly to the climber's harness, so A and C are unsafe practices, not correct precautions, and since they're wrong, D's "all of these" is wrong too.
