If you are uncertain which regulation applies to lockout/tagout, what should you do?

When faced with uncertainty regarding which regulation applies to lockout/tagout procedures, the most prudent approach is to apply the most stringent regulation. This ensures that safety is prioritized and that you are adhering to the highest standards of protection for workers. Lockout/tagout procedures are essential in preventing accidental machine start-up during maintenance or servicing, and adhering to the most stringent guidelines helps minimize the risk of workplace accidents.

This choice is based on the principle that in environments where safety is a concern, erring on the side of caution can lead to better outcomes. By applying the strictest regulation, you can ensure that all potential hazards are addressed, reducing the likelihood of accidents and injuries.

The other options do not adequately address the need for safety in uncertain situations. Applying the least stringent regulation could leave gaps in safety measures, while ignoring regulations entirely puts workers at serious risk. Consulting a supervisor can be valuable, but relying solely on a supervisor's input might not ensure the strictest practices are followed if they are unaware of the nuances between the potential regulations.
