Introduction Recent reviews of safety culture measures have revealed a host of potential factors that could make up a safety culture (Flin, Mearns, O'Connor, & Bryden, 2000; Guldenmund, 2000). However, there is still little consensus regarding what the core factors of safety culture are. The purpose of the current research was to determine the core factors, as well as the structure of those factors that make up a safety culture, and establish which factors add meaningful value by factor analyzing a widely used safety culture survey. Method A 92-item survey was constructed by subject matter experts and was administered to 25,574 workers across five multi-national organizations in five different industries. Exploratory and hierarchical confirmatory factor analyses were conducted revealing four second-order factors of a Safety Culture consisting of Management Concern, Personal Responsibility for Safety, Peer Support for Safety, and Safety Management Systems. Additionally, a total of 12 first-order factors were found: three on Management Concern, three on Personal Responsibility, two on Peer Support, and four on Safety Management Systems. Results The resulting safety culture model addresses gaps in the literature by indentifying the core constructs which make up a safety culture. Impact on Industry This clarification of the major factors emerging in the measurement of safety cultures should impact the industry through a more accurate description, measurement, and tracking of safety cultures to reduce loss due to injury. © 2013 National Safety Council and Elsevier Ltd.

Beam placement during bridge construction by a carriage moving across an abutment or pier, supporting the end of a beam or pipe to position and align it on the abutment. A lift assembly lowers the end and the carriage is disengaged and moved to receive another beam, placing multiple parallel beams, without requiring a large crane. A carriage formed in sections separates to return to a new position. A screw jack or hydraulic unit moves the lift assembly, and deposits the beam on a load plate, and opposed separately-operated lift plates connected by a hinged cross-bar may form a beam-receiving basket assembly. Carriage rollers bear against a channel iron that protects underlying concrete structure from damage. A first set of rollers may bear against a horizontal surface and a second set of rollers bear against a vertical face of the abutment, aligning the carriage and beam along orthogonal axes.

Provided is a charging system having a circuit for delaying power supply, and more particularly, a charging system having a circuit for delaying power supply installed on a side of a power supply apparatus, wherein the circuit for delaying power supply prevents a spark from being generated when an electronic device and the power supply apparatus are connected to each other. The circuit for delaying power supply blocks the power supply to the Vcc power terminal in the case in which the GND ground power terminal and the D signal terminal are not in an electrically shorted state and releases the blocking of the power supply to the Vcc power terminal because an operation of the transistor is changed and a charging state of the capacitor is changed in the case in which the GND ground power terminal and the D signal terminal become the electrically shorted state.
