According to OSHA regulations, when should a hoist drum rotation indicator be installed?

The correct answer indicates that a hoist drum rotation indicator should be installed on cranes manufactured after November 8, 2011, in accordance with OSHA regulations. This requirement stems from the recognition that cranes produced after this date incorporate updated safety features and technology that enhance operational visibility and safety. The installation of drum rotation indicators helps operators ensure accurate load handling and can prevent potential mishaps that may arise from improper positioning or movement of the load.

Cranes manufactured prior to this cutoff date are not mandated to have this feature under OSHA regulations, even though it might be beneficial as an operational safety measure. Therefore, the specific requirement for newer crane models emphasizes the ongoing improvement of safety standards within the industry.

The other options pertain to broader categories or situations that do not specifically align with this regulatory mandate, thereby making them less applicable in this context.
