There is a possibility that static electricity could ignite pyrotechnic compositions. Static discharge could cause the igniter to fire if the static discharge is directly across the fuse head of the igniter. A spark from body to ground through a composition could theoretically ignite pyrotechnic compositions. Common sense should be used: grounding yourself by touching a screw on a plug socket before handling pyrotechnics and avoiding wearing lots of synthetic clothing would minimize the risk of static problems.
