Deep Dive: G0B07
The correct answer is B: Confirm that the harness is rated for the weight of the climber and that it is within its allowable service life. What should be observed when climbing a tower using a safety harness is to confirm that the harness is rated for the weight of the climber and that it is within its allowable service life. Safety harnesses must be properly rated and not expired. For amateur radio operators, this is critical tower safety. Understanding this helps ensure safe tower climbing.
Why Other Answers Are Wrong
Option A: Incorrect. Always holding on with one hand isn't the key observation - harness rating and service life are more critical. One hand isn't the key. Option C: Incorrect. Fastening heavy tools to harness isn't the key observation - harness rating and service life are more critical. Tool fastening isn't the key. Option D: Incorrect. Since A and C are not the key observations, 'all of the above' cannot be correct. Only harness rating and service life are critical.
Exam Tip
Tower climbing with harness = confirm harness rated for weight and within service life. Think 'S'afety 'H'arness = 'S'ecure 'H'arness (rated and not expired). Safety harnesses must be properly rated and not expired. Not one hand, not tool fastening - just harness rating and service life.
Memory Aid
Tower climbing with harness = confirm harness rated for weight and within service life. Think 'S'afety 'H'arness = 'S'ecure 'H'arness. Safety harnesses must be properly rated and not expired. Critical tower safety requirement.
Real-World Example
Climbing a tower with a safety harness: Before climbing, confirm that the harness is rated for your weight (e.g., 300-pound rating) and that it's within its allowable service life (not expired or damaged). Safety harnesses have expiration dates and weight ratings - these must be checked. This is critical tower safety - confirm harness rating and service life.
