In the series of experiments carried out by Exit, a small pre- packaged charcoal burner was set alight and placed on the floor in a small car. The level of carbon monoxide inside the car was continuously monitored.
Other tests were carried out using a sealed 20ft shipping container as the closed environment. A brazier was loaded with 1.5 Kgm of good quality charcoal which was then set alight and placed in the centre of the floor. The container doors were shut (see Fig 6.10). Again, the carbon monoxide concentration within the container was continuously sampled from outside using a sampling probe.
