Guidance on Safety in Concrete Pumping
The aim of this guidance is to improve standards of safety during concrete pumping and reduce the incidence of collapse of concrete pump rigs and injuries due to incidents involving pressurisation of pipework or other equipment. As with all construction equipment, the safe operation of concrete pumps depends on a number of factors including the selection and maintenance of the pump and placing boom, the planning and supervision of their use and the competence of the operator and other personnel. If any of these are deficient, the risk of a serious accident increases significantly, so it is essential...
Tower crane safety on construction sites: A complex sociotechnical system perspective
Tower crane is the lifeline of the construction industry, but tower crane accidents are still too frequent. Despite the significant progress in tower crane safety research, system thinking-based approaches are lacking. The aim of this paper is to analyze tower crane safety from a complex sociotechnical system perspective through implementing both qualitative and quantitative analysis methods. Characteristics of five tower crane safety system components are summarized with a new framework comprised of five system-based levels based on Rasmussen's risk management theory. Fifty-six contributing...

Exploring the human and physical factors associated with telescopic handler overturning risks
A combination of machine instability and various human factors elements are important precipitating factors in telescopic handler overturn incidents. Industry guidance makes a number of assumptions about the impact of operator “knowledge gaps”, however the link between operator knowledge gaps and overturn risk is, at present, hypothetical and remains empirically untested. This study was done to identify: - the full range of human factors issues that might potentially contribute to telescopic handler overturn incidents; - the human factors issues that appear to be most important in terms...

AHP-based analysis of the risk potential of safety incidents
Case study of cranes in the construction industry The use of data collected from near-miss reports has added value to safety in high-hazard industries such as aviation and the process industry, but this procedure has not yet taken root in construction management practice. Although the management of near-miss reporting systems and the collection of near-miss event reports have been the focus of recent research efforts, the structural analyses of reports have not yet been investigated. This paper reports on a multi-phase research that studied near misses related to crane work and their safety risk...
Analyzing risk factors in crane-related near-miss and accident reports
Learning lessons from near-miss reports is a well-known procedure in various high-hazard industries. The construction industry tends to adopt near-miss management systems, but the procedure is relatively new and has not yet been fully explored or understood. Although the management of near-miss reporting systems in construction has been investigated, no effort appears to have been made to suggest a methodology for technically investigating the content of near-miss reported events. This paper reports a study that implemented both qualitative and quantitative analysis methods for a structured investigation...
NIOSH, Nail Guns, and Consensus Standards: Where We Stand
Recently, the American National Standards Institute (ANSI) released a revision to ANSI SNT-101, “American National Standard for Power Tools – Safety Requirements for Portable, Compressed-Air-Actuated, Fastener Driving Tools (ANSI SNT-101 2015)” (i.e., nail guns). NIOSH participated in the consensus process used to revise the standard. In all stages, NIOSH recommended changes that were consistent with the current scientific research about the safety risks attributable to nail guns, and interventions that are available to reduce them. Despite NIOSH's participation throughout...
Ergonomic design of crane cabin interior
The path to improved safety Many procedures in the development process of crane cabins today are still based on the specific experience of manufacturers and historical guidelines. It is not surprising that they fail to meet the needs of a large proportion of operators. Accordingly, the need for more objective, theoretically justified and consistent models, that will minimize crane operators' biomechanical and visual problems through anthropometric characteristic analysis to improve safety and prevent crane related fatalities and injuries, arises. In that aim we firstly identified the critical...

The work detailed in this current report is the third phase of MEWPs research...
A ‘normal accident’ with a tower crane? An accident analysis conducted by the Dutch Safety Board
Since cranes and tower cranes are complex installations they constitute critical aspects of safety at construction sites. The risks posed by cranes are specific and should be treated as such. Prior to assessing the impact of management and organizational factors, accident analysis should first start with an analysis of the actual accident process. The Dutch Safety Board conducted such an accident analysis involving a non-mobile, peak less, trolley tower crane. This tower crane collapsed at a Rotterdam building site on July 10th 2008. The results show that the flexibility of the configuration of...
Truck-mounted changeable message signs with symbols for work zone operations
Truck-mounted changeable message signs (TMCMSs) are desirable for scheduled and unscheduled short-duration work operations to inform drivers of unexpected conditions. Temporary traffic control for short-duration operations has been limited traditionally to arrow boards and static warning messages mounted to the work vehicle. With advances in technology, TMCMSs can fill a gap and provide drivers with better information about short operations and required actions by the driver. Through a study in a human factors laboratory, researchers evaluated message designs that incorporated text and graphic...
