A tower crane operator reports that load block drift has increased beyond normal parameters. What immediate action should the competent rigger take?

Option A: Reduce load capacity by 25%

Reducing load capacity does not address the underlying mechanical problem causing the drift and still allows operation of compromised equipment. Load block drift affects load control regardless of weight, so reducing capacity provides false security while maintaining dangerous conditions.

Option B: Increase inspection frequency to daily

Increasing inspection frequency while continuing operation ignores the immediate safety hazard and violates safety protocols. Daily inspections cannot prevent a catastrophic failure that could occur at any moment with compromised load control systems.

Option D: Document the condition and continue operation

Documentation alone without stopping operations is negligent and violates safety standards. While documentation is important, it must accompany immediate shutdown, not replace it when dealing with safety-critical equipment failures.
