Our checklists and checklist templates are licensed for personal use only. However, to avoid a bunch of emails, I will also say that I am okay with you doing almost anything with these checklists except posting the checklist (or anything you have created using the checklist template) on the internet or selling it. That includes permission to print and distribute as many paper copies of your checklist as you need. Don't remove the copyright or hyperlinks that I've included in the spreadsheet, though.
In professional diving, checklists are used in the preparation of equipment for a dive, and to ensure that the diver and life support systems are fully prepared before they enter the water. To a lesser extent, checklists are used by a minority of recreational divers, and by a larger proportion of technical divers during pre-dive checks. Studies have shown checklists to be effective at reducing the number of errors and consequent incidents.
