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.
From an employee who is assigned a job as a confined space technician, the process of getting a job lined up and getting staff to the job site with all the right equipment can be a mystery and probably taken for granted. For the Project Manager, getting the ok from a client to proceed with the job may be the easiest part of the project, its the logistics that can be the headache.
