On June 3, Nevada Gov. Jim Gibbons (R) signed into law a bill requiring construction workers to undergo mandatory 10-hour Occupational Safety and Health Administration safety training within 15 days of hire; supervisors must undergo 30 hours of OSHA training. The measure was enacted one year after Perini Building Co., a unit of Tutor Perini Corp., Framingham, Mass., and the Southern Nevada Building and Construction Trades Council agreed to end a 24-hour strike that erupted over six jobsite deaths within 18 months at the $8.6-billion CityCenter development on the Las Vegas Strip. The law becomes effective on Jan. 1, 2010. Employees who fail to produce proof of OSHA training must be suspended or terminated; employers must document and provide proof of training or face fines up to $1,000, as well as state sanctions.
