(Salem, OR)  --  Hot weather is forecast across Oregon and the State Fire Marshal is worried fireworks will spark fires.  Many cities and counties have tighter restrictions than state law allows for fireworks.  If you are allowed to use fireworks, have water available, use them on a non-flammable surface with a large perimeter, and place used or dud fireworks in a bucket of water for 15 to 20 minutes.  Oregon law prohibits fireworks that fly in the air, move more than 12-feet on the ground, or explode.
