RE: One Person Submersible From Plastic Drum Answered
The following is a quote of the post I've just left on the aforementioned Instructable (https://www.instructables.com/id/One-Person-Submersible-from-a-Plastic-Drum/?&sort=NEWEST&limit=40&offset=40). I would really appreciate the removal of this instructable.
"Hi. I am a certified OSHA and CSAO commercial diver air dive supervisor, level 1, and qualified Master Scuba Diver Trainer with the Professional Association of Diving Instructors.
This is a very dangerous idea. You might not die, but someone else might/will/and has.
Just because there is a disclaimer there, you and Instructables will be subject to litigation. There is a reason that people need a certification to operate this type of life support equipment.
"Because of Boyle's law, maximal changes in volume occur in the 4 feet (1.22 m.) closest to the surface and the diver sustains a tear in the pulmonary parenchyma with the escape of air into the pulmonary venous outflow."
I can quote other resources, such as the US Navy Dive Manual and the DCIM manual, but it's Boyle's Law, not Boyle's "kinda' might happen. I don't know". "
