A sparkler, is a type of hand-held firework, that burns slowly while emitting colored flames, sparks, and other effects. In the United Kingdom, a sparkler is often used by children at bonfire and fireworks displays on Guy Fawkes Night, the fifth of November. Sparklers are responsible for the vast majority of legal firework-related injuries, primarily as a result of their widespread sale in areas where other forms of fireworks are banned. The most common situation for injuries occurs when lit sparklers are given to unsupervised children, many of whom may not understand the risks. The devices burn at a high temperature (as hot as 1800 to 3000° F, or 1000 to 1600° C), depending on the fuel and oxidizer used, more than sufficient to cause severe skin burns or ignite clothing. Safety experts recommend that adults ensure children who handle sparklers are properly warned, supervised and wearing non-flammable clothing which cannot catch fire easily.
