Flame retardants prove ineffective on fresh-cut Christmas trees
Date:12/12/2008

PULLAUP, WA This Christmas season, think twice about spending money on a commercial flame retardant for your Christmas tree. The good, old-fashioned methodkeeping your tree in a container of fresh wateris probably all you need to keep your tree green and healthy. Researchers have determined that some flame retardants don't work on cut Christmas trees; in fact, in several cases the chemical retardants sped up the drying process and made trees more flammable.

Drs. Gary Chastagner, professor of plant pathology at Washington State University's Puyallup Research Center, and Eric Hinesley, professor of horticulture at North Carolina State University, tested two flame retardants on Douglas-fir and Fraser fir, two of the favorite Christmas tree species in the United States.

According to Chastagner, many cities and municipalities require that chemical flame retardants be used on cut Christmas trees displayed in public buildings. However, the assumption that all flame-retardants are effective on Christmas trees had not been proven. Additionally, there is little information available about the effect of flame-retardants on the quality of trees or boughs. Chastagner and his colleagues wanted to determine if two particular flame-retardants reduced the potential for fire, and find out what effect the chemicals had on the quality (needle retention and moisture status) of the trees.

Surprisingly, neither product tested in the study showed any benefit to the quality or life of the trees. In fact, the chemical used on Douglas-fir caused the branches to dry much faster than non-treated branches. Because ignition from a small source, such as a match, only occurs below a certain moisture level, branches treated with the flame retardant became a fire hazard quicker than non-treated branches.

Because freshly cut Douglas-fir and Fraser fir Christmas trees are almost impossible to ignite and burn when exposed to a small flame, tests were conducted o
