Where should the key for the lockout device be kept?

The most appropriate location for the key for the lockout device is with the maintenance director. This ensures that the key is managed by an individual responsible for overseeing maintenance operations and safety protocols. The maintenance director typically has the training and knowledge to ensure that lockout/tagout procedures are followed correctly, which helps prevent accidental machine startup during maintenance work.

This approach is consistent with safety regulations that promote the idea that keys should be controlled by authorized personnel who understand the importance of maintaining safe work environments. It also provides accountability, as the maintenance director can ensure that the key is only accessible to trained staff, minimizing the risk of unauthorized access that could compromise safety protocols.

While other options might suggest keeping the key with individuals or in locations where it could be easily accessed, they do not offer the same level of control or responsibility as having it with the maintenance director.
