![]() and Balfour Beatty have mandated that, by January, all lifts on their projects must have secondary guarding systems, and other major contractors are considering it. So-called “primary guarding” systems, such as foot pedals, are not always enough to protect crushing injuries and are easily defeated through tampering, experts note. “It’s like an ‘undo’ button on your computer,” said Jeff Ford, JLG’s global product director, at last year’s Lift and Access Showcase in Las Vegas. SkySiren, which can be retrofitted on many different models, incorporates audio-visual warnings and a protective cage, while the JLG-specific SkyGuard automatically reverses the sequence of operations that led to the activation. Each system uses a protective barrier linked to a pressure switch, which can disable the lift. Genie Industries’ SkySiren and JLG’s SkyGuard are among the leading safety technologies-known as “secondary guarding” systems-available in the U.S. Sixteen entrapment deaths were reported to the association in 2013. In 2014, the non-profit International Powered Access Federation (IPAF) recorded 64 construction deaths involving lifts, 11 caused by entrapment. “Other incidents like this have occurred because most operators aren’t thinking about what could happen if they got pinned.”Įntrapment is a common fact pattern for lift accidents. ![]() “What happened with Walsh isn’t a one-off incident,” says Steve Smithgall, senior vice president of loss control for Balfour Beatty Construction. The lift became pinned against the underside of the bridge, which spans the Ohio River between Indiana and Kentucky and Cox was found unresponsive in the lift basket. The accident occurred in April 2012 when Roger Cox, a 50-year-old union journeyman carpenter and welder hired by Walsh in 2011, was operating the JLG model 860SJ telescopic boom lift to perform weld bracing. Based on evidence provided by Walsh, the judge ruled that the worker was properly trained and supervised in operation of the boom lift that pinned him against an overhead piece of the bridge. In many cases, experts say, entrapment occurs while the operator is repositioning the lift in others, the operator leans onto the controls and sustains a crushing injury or even death.Īn Indiana judge has now dismissed safety violations against Chicago-based Walsh Construction arising from the 2012 death of an employee working on the Milton-Madison Bridge in Indiana. Considering various factors like cost etc., the mechanical push to exit bars can be used with electric strike locks NU881P1D designed exclusively for the purpose.A recent accident investigation and safety enforcement in the Midwest illustrates the problem of “entrapment”-that is, when an operator of an aerial work platform is crushed between the machine and a nearby obstruction. In European Union, the panic bars Comply EN1125 & EN179 standards. Standard for Positive Pressure Fire Tests of Door Assemblies. Using these with fire exit doors, the unit generally must & should comply with UL10C i.e. The mechanical type are generally designed as push to exit while as electrified version can be integrated with the access controls and card readers to make it appear & use as perfect access control system. ![]() The panic bars are generally of two types, mechanical & electrified or electro mechanical. The main purpose of panic bar is to allow the user to leave the site in case of emergency without having the prior knowledge of the exit plan. ![]() ![]() Push bars, sometimes referred as panic bars or crash bars, allows the user to open the door by pressing the push rail or crossbar. ![]()
