  • Compact Fluorescent Lamps (CFLs) - An energy saving alternative to standard (incandescent) light bulbs, CFLs use less wattage to give you the same lighting power as a larger wattage standard bulb.
  • Lightning kills nearly one hundred people every year in the United States and injures hundreds of others. When you first notice an upcoming storm, remember that lightning usually precedes rain. Go to the nearest building or car and stay inside until the storm has passed. Do not wait until the storm begins to take cover. Protect yourself and your family by moving to a safe place. Stay in the safe place until signs of lightning and thunder have been past for thirty minutes.
