Under ventilated container burn

This is an example of an under ventilated container burn. The objective is to show how oxygen effects the heat release rate and the temperature of the fire. And how the visual situation changes during the burn. No water is used. Look especially at the picture in the TIC about 5-10 seconds after the door is opened every time. For me the term "under ventilated" means the same thing as the terms "ventilation limited", "oxygen limited" and "ventilation controlled". For me they all indicate that the fire is reduced in heat release rate due to a lack of oxygen, more or less. In this case the burn was done for the camera, but normally a class of students would be inside.
