• Blue and red lights were retrofitted onto three forklifts and used for four months in a warehouse environment to increase the awareness of approaching vehicles. • A short list of open-ended discussion questions pertaining to the retrofit lights was administered to nine employees who were operators and pedestrians. • Feedback indicated that all nine employees thought the addition of the lights increased the visibility of the forklifts and improved safety by making the vehicles more conspicuous.

pertain to an organization's prioritization of safety relative to other concerns, such as productivity or quality control (Naveh, Katz-Navon & Stern, 2011; Zohar, 2000). Relating to what organizations may prioritize, safety climate also entails the kind of behaviors that are expected, supported and rewarded (Schneider, 1990). Characteristics of safety climate can impact workers' own safety values, which, in turn, influence their behaviors (Naveh, et al., 2011). Further, a positive safety climate has been linked to less burnout and fewer errors, near-hits and incidents that result in lost time from work (Christian, Bradley, Wallace, et al., 2009; Nahr-gang, Morgesun & Hofmann, 2011). In this sense, not only has safety climate been identified as a potential leading indicator of incident occurrence, but also evidence exists that a positive safety climate might strengthen the impact of job factors (e.g., job autonomy, supervisor support, coworker support) on workers' proactive behavior (Bronkhorst, 2015), although these factors are not well understood (Parker, Axtell & Turner, 2001). To that end, this article examines what role job autonomy, in particular, may have in forming workers' perceptions and subsequent OSH performance on the job. The authors begin by defining autonomy in the workplace to provide a consistent platform for studying the term.

Tool box talks (TBTs) have the potential to improve communication, empower workers, reduce injuries and improve safety; however, they can also be "missed opportunities" for providing important safety messages in construction. The goal of this paper is to share the results from two research projects designed to improve the frequency, delivery, participation, and outcomes of TBTs. The results of these projects provide suggestions for planning and delivering TBTs in construction.

Methods: In the first project, 86 residential carpentry foremen from 8 different residential contractors in the St. Louis region participated in training for delivering TBTs as part of an 8-hour fall prevention and safety communication intervention. We compared baseline measures of safety behavior and fall prevention knowledge items to follow-up between participating foremen and their crewmembers. Concurrently, surveys of 300 apprentice carpenters were collected to describe the frequency and delivery methods of TBT and to serve as a comparison group for the TBT intervention. In the second project, we evaluated the utility of ergonomics TBTs delivered by a safety representative to 36 carpenters and laborers. Workers rated their perceptions of topic relevance, delivery method, similarities to traditional TBTs, and intent to change behaviors. The safety representative provided feedback regarding the TBTs and reported their observations of improved worker use of ergonomics in work tasks post-training.

Discussion / conclusions: Both interventions described in this paper improved workplace safety. The interventions demonstrate how to simply shift from non-collaborative TBTs to participatory, context-driven TBTs by using a pre-printed TBT template, modified to address the hazards present at the worksite. Delivery suggestions relate the information to the workers, and include workers in the identification of problems and safety-related solutions. These participatory methods for preparing and delivering TBTs have the potential to improve construction workplace safety practices.

Use of a pneumatic nail gun with a sequential actuation trigger (SAT) significantly diminishes the risk for acute traumatic injury compared to use of a contact actuation trigger (CAT) nail gun. A theoretically-based increased risk of work-related musculoskeletal disorders from use of a SAT nail gun, relative to CAT, appears unlikely and remains unproven. Based on current knowledge, the use of CAT nail guns cannot be justified as a safe alternative to SAT nail guns. This letter provides a perspective of ergonomists and occupational safety researchers recommending the use of the sequential actuation trigger for all nail gun tasks in the construction industry.

Millions of U.S. workers are at risk for a work-related motor vehicle crash. Fatality data show that across all industries, motor vehicle crashes are consistently the leading cause of work-related fatalities. Of 43,025 work-related fatalities reported by BLS between 2003 and 2010, 10,202 were the result of single- or multiple-vehicle crashes of workers driving or riding in a vehicle on a public roadway, and 2,707 were pedestrian workers struck by a motor vehicle. During the same period, an additional 2,487 workers died in crashes that occurred off a public roadway or on industrial premises (BLS, 2013).
