At the end of the test, check the cylinder pressure to ensure that there is still an adequate supply left for a hypoxic death.
Creating a Zero-Oxygen Environment The Exit Bag
For a happy hypoxic death,you will need to create an environment of inert gas. The simplest way to achieve this is to use a plastic Exit bag.
Making an Exit Bag
While different people make slightly different bags, the standard Exit bag involves a plastic bag of:
• a reasonable size • a suitable soft plastic • a neck band of elastic that allows the bag to make a snug, but not tight, fit around a person’s neck
The method used by ‘Nurse Betty’ is shown in the accompanying video. A reliable and effective bag can be assembled in a few minutes. The components are:
Plastic bag - PVC 35cm x 50cm x 50 micron is a good size or Poly clear LDPE 75 micron, or a large polyester ‘oven bag’ see ‘A & B’
• 1 metre of 10 mm wide elastic, ‘D’ • 1 toggle (or other fastener) to adjust elastic length • 1 roll of 20mm sticky tape ‘C’ (Micropore or equivalent) • 1 small roll of ~ 35 mm plastic duct tape • Pair of sharp scissors
