highway agency preliminary implementation of maintenance work zone Safety Devices
INTERNATIONAL FORUM ON ROAD SAFETY RESEARCH - BANGKOK THAILAND OCTOBER 25-27 1995. (VTI KONFERENS), 1996Co-Authors: F HanscomAbstract:This paper reports results of SHRP-sponsored emerging technology and the preliminary implementation by operating highway agencies of a variety of highway maintenance work-zone traffic control Devices. At the time of this writing, a number of the innovative traffic control Devices discussed in this paper were being evaluated by state highway agencies. As most formal results of these evaluations were still a year away, findings contained in this paper are limited to device descriptions, manufacturer sources, and preliminary evaluation results. For the covering abstract of the conference see IRRD 493717.

highway evaluation of maintenance work zone Safety Devices
Strategic Highway Research Program (SHRP) and Traffic Safety on Two Continents Proceedings of the ConferenceSwedish National Road and Transport Resear, 1994Co-Authors: F Hanscom, Jerry Graham, D StoutAbstract:Open highway testing is the evaluation of a device operated or used under actual highway conditions by State maintenance forces. Open highway testing was performed on Devices in actual maintenance work zones. The following Devices were tested: Portable Speed Bump; Flashing Stop/Slow Paddle; Infrared and Ultrasonic Intrusion Alarms; Queue-Length Detection Alarm; Direction Indicator Barricade; Opposing Traffic Lane Divider; Remote Driven Vehicle. This paper summarizes observational procedures, results, and recommended implementation strategies for each device.

maintenance work zone Safety Devices development and evaluation
1993Co-Authors: D Stout, Jim Graham, J. Fish, F HanscomAbstract:This report presents the findings of tests and evaluations of several new work zone Safety Devices. The prototypes of the 25 Devices were designed, developed, fabricated, tested, evaluated, and refined. The Devices were organized into 7 groups: barriers; warning Devices; rumble strips; delineation Devices; lighting Devices; signs; and promising concepts. Twelve Devices successfully passed the evaluation stage: salt spreader/truck mounted attenuator interface; the portable crash cushion; the ultrasonic detection alarm; the infrared intrusion alarm; the queue length detector; the portable rumble strip; the direction indicator barricade; the opposing traffic lane dividers; the snowplow blade markers; the flashing stop/slow paddle; the portable sign and stand; and the remotely driven vehicle.

dynamic response of a rollover protective structure
Computer-aided Civil and Infrastructure Engineering, 2008Co-Authors: David Thambiratnam, Brian Clark, Nimal PereraAbstract:Roll Over Protective Structures (ROPS) are Safety Devices fitted to heavy vehicles to provide operator protection during an accidental roll over. Currently, ROPS design standards require full-scale destructive testing that can be expensive, time consuming, and unsuitable for small companies. More economical analytical methods are not permitted due to a lack of understanding of post yield behavior and the energy absorption capacity of ROPS. To address this, a comprehensive research project was undertaken to investigate ROPS behavior using analytical techniques supported by experiments. This paper presents the dynamic impact analysis of a bulldozer ROPS using calibrated finite element models. Results indicate that: 1) ROPS posts have significant influence on the energy-absorbing capacity, 2) dynamic amplifications in energy could be up to 25%, 3) stiffer ROPS cause high peak decelerations that may be detrimental to the operator, and 4) analytical techniques may be used for evaluating ROPS performance.

Faculty of Built Environment and Engineering, 2008Co-Authors: David Thambiratnam, Brian Clark, Nimal PereraAbstract:Roll Over Protective Structures (ROPS) are Safety Devices fitted to heavy vehicles to provide protection to the operator during an accidental roll over. At present, ROPS design standards require full scale destructive testing which can be expensive, time consuming and unsuitable for small companies. More economical analytical methods are not permitted due to a lack of understanding on post yield behaviour and energy absorption capacity of ROPS. With this in mind, a research project was carried out to comprehensively investigate ROPS behaviour using analytical techniques supported by experiments. This paper presents the dynamic impact analysis of a bulldozer ROPS using calibrated finite element models. Results indicate that (i) ROPS posts have significant influence on the energy absorbing capacity,(ii) dynamic amplifications in energy could be up to 25% and (iii) stiffer ROPS cause high peak decelerations that may be detrimental to the operator. The feasibility of using analytical techniques for evaluating ROPS performance has also been demonstrated.

sharps injury reduction Safety training and manufacturer support
British Journal of Healthcare Management, 2015Co-Authors: Debra AdamsAbstract:Despite the legislation EU Directive 2010/32/EU on prevention of sharps injuries being in force for two years now, research shows that not all NHS trusts have revised and published their sharps policy—only 84% have. Furthermore, 33% of trusts have not instructed staff to use Safety Devices, and out of the staff who require sharps Safety training, only just over half have received it. This article emphasises the importance placed on training by the directive, and explains how partnering with a manufacture who offers ongoing support can help with an effective conversion to Safety-engineered Devices (SEDs). It is important for trusts to select a manufacturer who not only offers high-quality SEDs but also provides a full support package, offering appropriate bespoke training, as well as ongoing advice, robust Safety policies/procedures and help with risk assessments. These points are supported by comments from various trusts who have already converted to SEDs from their experiences.

organizational climate staffing and Safety equipment as predictors of needlestick injuries and near misses in hospital nurses
American Journal of Infection Control, 2002Co-Authors: Sean P Clarke, Joan L Rockett, Douglas M Sloane, Linda H AikenAbstract:Abstract Background: Recently passed federal legislation requires institutions to adopt Safety equipment to prevent needlesticks, but there is little empirical evidence of the effectiveness of specific types of Safety Devices or the contribution of Safety Devices to reducing needlesticks relative to the contributions of staffing, organizational climate, and clinicians' experience. Method: In 1998, 2287 medical-surgical unit nurses in 22 US hospitals were surveyed in regard to staffing and organizational climate in their hospitals and about patient and nurse outcomes, including needlestick injuries. Hospitals provided information about available protective Devices at the time of the survey. Relationships between nurse and hospital characteristics and protective equipment and the likelihood of needlestick injuries and near-miss incidents were examined. Results: Poor organizational climate and high workloads were associated with 50% to 2-fold increases in the likelihood of needlestick injuries and near-misses to hospital nurses. Capless-valve secondary intravenous set systems and use of any type of protective equipment for IV starts or blood draws were associated with 20% to 30% lowered risks of both event types. Conclusions: Nurse staffing and organizational climate are key determinants of needlestick risk and must be considered with the adoption of Safety equipment to effectively reduce sharps injuries.
