Safety Belts: Most hyperbaric chambers that are rated for 20 psi should have safety belts based on all the people that I have talked to. Having safety belts add safety to the chamber and the belts seem to add longevity to the chamber even though they are only being inflated to 4.3 psi. When I rent chambers, I don't know if people are doing things to a
I would recommend any chamber pressure tested for 15 psi to have straps for added safety. If it is over that it is another story.
There are two types of safety belts on the market.
Solid Steel: A little heavier but looks a little nicer. The company that has the steel buckles has been making them for 4 years like this and so far have not had a single problem with their chambers with the steel buckles. They have just recently did this. They have been in the chamber business for over 30 years as of 2012.
Composite (a super hard plastic): This is a little lighter and comes on the 23 inch models usually. The steel and composite serve the same function. The only thing different is the looks. The chambers with the belts to help assist have been cleared for acute altitude sickness and their chambers are strong enough to have 20 psi. They are also made in the USA. There are many safety belt style chambers all over the state. Many people who have bough them from me are willing to give a free session to those that have a prescription. Email me here if you want me to try to locate someone in your area that is willing to let you have a free session.
For anyone willing to let others come and have a free session I will make an equal energy exchange.
