In America，Virginia Beach has all the elements of a classic seaside resort：brilliant beaches，a lively boardwalk，plenty of restaurants and nightspots，and amusement rides sure to appeal to kids．Many believe Virginia Beach is at its best in the off-season，when the town is less crowded but the weather is still mild．

Meanwhile，some safety tips should be followed，enjoying the happiness and excitement the beach offers．

The number l safety tip concerns ocean safety：pay attention to Flag conditions posted on the lifeguard stands．Lifeguards post a red flag to warn when the ocean water is dangerous．Take them seriously! Tourists from land-locked regions are particularly easily attracted by the magic of the waves．However，a calm ocean can become risky without warning．Make sure you swim near a lifeguard．Swimming without lifeguard protection is almost five times as great as drowning at a beach with lifeguards．

Never swim alone．Many drownings involve single swimmers．When you swim with someone else，if one of you has a problem，the other may be able to get help，including signaling for assistance from others．

Don't fight the current．The facts show that some 80％ of rescues by lifeguards at ocean beaches are caused by currents．These currents are formed by surf and gravity，because once surf pushes water up the slope of a beach，gravity pulls it back．This can create concentrated rivers of water moving offshore．If you are caught in a rip current，don't fight it by trying to swim directly to shore．Instead，swim parallel to shore until you feel the current relax，then swim to shore．Most rip currents are narrow and a short swim parallel to shore will help bring you to safety．

2008年6月8日7时许，某村村民杨XX租用邻村毕X的联合收割机收割小麦，雇佣司机张X正在开车收割小麦中，车主毕X登上了收割机的麦仓，当其发现前方的田间低压线路时，便在收割机上喊叫并用麦粒撒向驾驶室试图让司机停车，但司机没有察觉，当收割机在低压线下通过时，毕X后颈部碰触带电低压线，造成低压触电死亡。

经现场勘察，涉案低压线路产权属某村，低压带电导线对地距离4米，收割机高度2.85米。

死者家属李X等5人向法院提起民事诉讼，要求某村村委、某供电公司两被告赔偿死亡赔偿金、丧葬费、被抚养人生活费等169585元。
