Frequently asked questions
Does this replace a written permit?
It captures the data the permit requires but most jurisdictions also expect a printed/signed permit document. Print this checklist as the back-up record after entry.
Who can be the attendant?
A trained authorized employee, separate from any entrant. The attendant must remain outside, maintain communication, and never enter to attempt rescue unless they are part of a designated rescue team and properly equipped.
