With the three-day 4th of July holiday weekend starting tomorrow, the Danbury Fire Marshal's Office is reminding residents of some safety tips when using sparklers. The Fire Marshal suggests avoiding buying fireworks that are packaged in brown paper because this is often a sign that the fireworks were made for professional displays and that they could pose a danger to consumers. People using sparklers and fountains are reminded not to have any part of the body be directly over a device when lighting the fuse and to back up to a safe distance immediately after lighting the fuse. Sparklers and fountains should not be carried in a pocket or ignited in a metal or glass container. You should never try to re-light or pick up fireworks that hasn't ignited fully. A bucket of water or a garden hose should be nearby in case of a mishap.
