Final answer:
Yes, it is true that when a compactor or baler is not operational, they must be locked and tagged out as per OSHA guidelines to ensure safety.
Step-by-step explanation:
When a compactor or baler is not operational, OSHA guidelines require that the equipment be locked out and tagged out (LOTO). This is to ensure that no one accidentally starts the machine while it is in a state of disrepair, which could lead to injury or death. The process of lockout/tagout involves placing a lock and tag on the power source of the equipment to prevent it from being energized. Proper LOTO procedures protect workers from the release of hazardous energy during service or maintenance activities. The answer to the student’s question is True; equipment like a compactor or baler must be locked and tagged out when they are not operational.
