A body suit is composed of ozone-resistant material, typically Tyvek
or nylon, which is sealed at the wrists, neck and ankles (if there are
no attached booties). It is necessary to shower first and then enter
the suit while still wet, to aid ozone transference.
It's also recommended to use a skin exfoliant cloth or sponge while in the shower.
The silicon tubing
from the generator is introduced into the suit either through the neck or leg
opening or up the sleeve. Ozone is introduced for somewhere between 30 - 60 minutes at a rate
of 1/16 or 1/8 l/m. Then you turn off the oxygen tank and ozone generator and sit there for an additional 30-45 minutes.
Because of the large volume, no outlet for excess
gas is required. This method is unpopular due to the clammy feel of the
suits as the wet skin surface cools. Personally though, it wasn't all that bad.
One way to partially avoid the clamminess is to heat up the room before you start so you will start sweating nearly immediately.
You just got to get used to not moving around
a-lot while your inside the suit.
