Abstract
The influence of air flow on burns under a fabric exposed to intense thermal radiation was studied. It was determined that both ignition of cloth and the heat transferred to a backing are affected by air supply, air movement or wind. The effects are as high as a factor of 2 for air supplies or movements normally encountered. Mounts for fabrics or objects near the irradiated cloth may appreciably influence air supply or movement. The effect of air supply or flow on cloth combustion is anomalous; little or no air will smother a flame or glow, normal drafts or wind will remove volatile products, cool the fabric and thereby inhibit ignition. A slight air movement of approximately 1 fps provides optimum oxygen, minimal cooling and minimum energy for ignition. Flash burns behind clothing often result when there is no cloth ignition, especially when there is no separation between cloth and backing; for this situation the effect of air flow is also appreciable.
