Review of construction employer case studies of safety and health equipment interventions
Lowe Brian D , Albers James , Hayden Marie , Lampl Michael , Naber Steven , Wurzelbacher Steven . J Constr Eng Manag 2020 146 (4) This paper presents a review of 153 case studies of equipment interventions to improve safety and health of construction businesses in Ohio in 2003-2016. These represent $6.46 million (2016 USD) in purchases incentivized through the Ohio Bureau of Workers' Compensation (OHBWC) Safety Intervention Grant (SIG) program. The source data in the review were extracted from employer grant applications and final reports of the case studies. Results were aggregated by type of construction equipment and included the reduction in safety and ergonomic hazards (risk factors for work-related musculoskeletal disorders), and an assessment of the quality of the case studies as determined through criteria established by the authors. Equipment associated with greatest reduction in risk factors and with case studies of higher quality were electrical cable feeding/pulling systems, concrete sawing equipment, skid steer attachments for concrete breaking, and manlifts (boom lifts). This review illustrates challenges in demonstrating efficacy of equipment interventions to improve construction safety/health-even from case studies within a structured health/safety program. The authors are aware of no other systematic review of case studies reporting on experiences with health/safety intervention equipment specific to the construction industry. 2020 American Society of Civil Engineers. |
A biomechanical assessment of hand/arm force with pneumatic nail gun actuation systems
Lowe Brian D , Albers James , Hudock Stephen D . Int J Ind Ergon 2014 44 (5) 715-722 A biomechanical model is presented to estimate user hand/arm force exertion with two pneumatic nail gun trigger systems. The sequential actuation trigger (SAT) is safer than the contact actuation trigger (CAT) but increases the user's exertion of force because the trigger must be actuated after the safety tip is held pressed against the workpiece. Time integrated hand force was calculated for a single user based on direct measurement of nail gun tip force against the workpiece (tip contact) and from estimated force to support the tool weight during transfer between nails and during idle holding. The model shows that hand/arm force increases when nailing with the SAT (relative to CAT) and with a vertically-oriented workpiece (relative to horizontal). Expressed per nail fired, the user exerted 0.13Ns (horizontal orientation) and 2.88Ns (vertical orientation) integrated hand force during tip contact with CAT compared to 26.15Ns (horizontal) and 46.08Ns (vertical) with SAT. Depending upon idle holding duration, integrated hand force during tip contact was estimated to have been 1-3% of 48-132Ns total hand force with CAT and 21-44% of 83-167Ns total hand force with SAT (average of horizontal and vertical orientations). Based on standard time allowances from work measurement systems it is proposed that efficient application of hand force during tip contact with SAT can reduce this contribution to 6-15% of 55-139Ns total hand force. The model is useful for considering differences in hand/arm force exertion between the SAT and CAT systems. RELEVANCE TO INDUSTRY: This paper presents a model of hand/arm force associated with two types of pneumatic nail gun actuation (trigger) systems. The model clarifies differences in user force exertion with the sequential actuation and contact actuation triggers to inform nail gun trigger selection decisions. |
