Where should work permits be posted when working in confined spaces?

Work permits should be posted outside the entrance of the confined space to ensure that all personnel involved in the work are aware of the activities taking place within that space. This location allows for visibility and access for all employees and emergency responders without having to enter the confined space, which could pose additional risks.

Posting permits outside helps in communicating critical information such as the nature of the work, any hazards identified, safety procedures in place, and the personnel authorized to enter. This method enhances safety by promoting awareness and preparedness among all workers in the vicinity, thereby reducing the likelihood of misunderstandings or accidental entries into the confined area.

Other locations, such as inside the confined space, would limit the visibility of the permit to those who are already inside, which could be hazardous if unforeseen circumstances arise. The ceiling of the confined space may be difficult to access for reading the permit, making it less effective. While having the permit in the main office may provide a record, it does not serve the immediate safety needs of those working at or near the confined space.
