When a confined space rescue standby team arrives on a site there are many documents they require. A hazard assessment, entry procedure, rescue procedure, possibly an entry permit, WHIMIS info, gas monitor paperwork and likely a few more that I have missed. The hole watch / rescue team leader could easily be looking at a minimum of 30 pages of documents. One could argue that these are no longer simply onsite procedures to be reviewed, but rather are competing with War and Peace. And just like reading such a novel, once you get to page 30, your memory of what was at page 1 will be limited.
An industrial confined space rescue team has a distinct advantage over a public services one, such as a fire department. They have the ability to know when and where an entry is going to occur as well as the tasks to be completed within it. To ensure they can utilize this information, the rescue resources should be involved in the pre-entry preparation process.
An essential part of this preparation is the toolbox/tailboard talk. During confined space entries the rescue plan is often not considered until it is required, which is often too late. Either those that are part of the entry work do not discuss their assigned rescue duties or the designated rescue team is seated on the sidelines waiting to be called into action. There is critical information that can be shared to contribute to a successful response.
