What is the one rule for interlocks or built-in safety devices?

The rule for interlocks or built-in safety devices is to never defeat or bypass them. These safety mechanisms are designed to prevent accidents and ensure safe operation of equipment or machinery. When interlocks are disabled, it compromises the safety they provide, potentially leading to hazardous situations that could result in injury or even fatal accidents.

Safety devices are put in place for a reason—they protect operators and those in the surrounding area by ensuring that certain conditions are met before a machine can be operated. Bypassing these safety features undermines their purpose and can lead to dire consequences, highlighting the importance of respecting and adhering to this rule in any operational environment.

It's crucial to recognize that using interlocks as intended not only adheres to best safety practices but also complies with legal and organizational safety standards, further emphasizing their importance within industrial and mechanical settings.
