Abstract: | Burn tests were conducted on a number of Christmas trees commonly used in typical households. Trees were kept in room conditions for several weeks to dry out. Burn tests were also conducted on fresh and almost fresh trees to compare their burning behaviors wilth those of dry trees. Two trees were moistened and wetted prior to burn to observe the effects of water on burning of dry trees. The foremost objective of this work was to quantitatively demonstrate the potential fire hazard of Christmas trees by measuring the rate of heat release and room temperature during the burn. |
