Don't allow fireworks in the home and instead go to a professional display. Watch for hot tar and coals on the beach, and discard your own coals in a designated receptacle. Never leave a fire unattended. Never play games near a fire pit or campfire. Never use sand to extinguish a campfire.
Sand insulates heat.
Douse all campfires with water. Keep clothing irons and curling irons out of the reach of children. Keep children out of the kitchen when cooking. Keep hot liquids away from table and counter edges and turn pot handles in on the stove. Use caution when removing the wrapping or lids from microwaved or steamed food steam cause serious burns.
