Are limited permits valid for more than one entry into a confined space?

Limited permits for confined spaces are designed to ensure safety during specific, controlled entry scenarios. They typically authorize just a single entry into the confined space and are supposed to be used for a defined duration and purpose. Once the work related to that particular entry is completed, the permit becomes invalid.

This approach is grounded in safety protocols that address the risks associated with confined spaces, such as hazardous atmospheres or entrapment, which can vary significantly with each entry. Having a new permit for each entry ensures that the conditions are reassessed, and the necessary safety measures are maintained without assuming that previous assessments remain valid for future entries. Thus, a limited permit is not valid for multiple entries, emphasizing the need for vigilance and thorough evaluation at each step of the confined space entry process.
