Speaking of fireworks, don't let your propane tank become one. The National Fire Protection Agency
says propane-related grilling accidents cause more than 6,000 fires and explosions annually, resulting in 20,000 ER visits, and at least 20 deaths. Since propane expands in extreme heat, be sure to keep tanks out of your car. If you smell gas, or if your tank runs out after only a few uses, apply soapy water to the valve base and tank seams. If the solution bubbles, there's a leak. So stand back and call the fire department. Be sure to check for leaks every time you change the tank.
