May 11, 2006 May 11, 2006 ROSEMEAD, Calif., May 11, 2006—Southern California Edison (SCE) is encouraging everyone this weekend to hold on to their party balloons as they honor their mom on Mother’s Day. “Both latex and metallic balloons can float into power lines, and that can cause power outages and even injure people on the ground,” said Jack Sahl, SCE director of environmental, health and safety. “Celebrate Mother’s Day, but don’t ruin the occasion by releasing balloons outside and having them knock out power.” The number of metallic balloon-caused power outages has risen sharply in California in recent years and spikes alarmingly around Mother’s Day in May and during June when people are celebrating graduations. SCE experienced a record 414 balloon-caused service interruptions in 2005, up from 395 in 2004. SCE recommends these simple safety rules for handling metallic balloons: Do not attempt to retrieve a balloon—or any foreign object—tangled in power lines. Instead, call SCE at 1-800-611-1911 and report the problem. Keep metallic balloons indoors, and never release them outside. Never attach metallic streamers to any balloon—latex or metallic. Never bundle metallic balloons together. Be sure to secure a helium-filled balloon with a weight heavy enough to prevent it from drifting away. (It is unlawful to sell metallic balloons without a string weight.) Never go near a downed or dangling wire. Keep others away and contact the police or fire department and call SCE at 1-800-611-1911 for assistance. More information on safety and a host of other topics can be found at www.sce.com.
