ABSTRACT Nail guns are a common source of acute, and potentially serious, injury in residential construction.
Data on nail gun injuries, hours worked and hours of tool use were collected in 2008 from union apprentice carpenters (n=464) through classroom surveys; this completed four years of serial cross-sectional data collection from apprentices. A predictive model of injury risk was constructed using Poisson regression.
Injury rates declined 55% from baseline measures in 2005 with early training and increased use of tools with sequential actuation. Injury rates declined among users of tools with both actuation systems, but the rates of injury were consistently twice as high among those using tools with contact trip triggers. DISCUSSION AND IMPACT: Nail gun injuries can be reduced markedly through early training and use of tools with sequential actuation. These successful efforts need to be diffused broadly, including to the non-union sector.

    ABSTRACT: Nail gun use is ubiquitous in wood frame construction. Accessibility and decreasing costs have extended associated occupational hazards to consumers. Compelling evidence documents decreased injury risk among trained users and those with tools with sequential triggers. To prevent inadvertent discharge of nails, this safer trigger requires the nose be depressed before the trigger is pulled to fire. The sequential trigger is not required by the Consumer Product Safety Commission (CPSC) or the Occupational Safety and Health Administration (OSHA) nor are there any guidelines for training. We collected data from personnel at 217 points of sale/rental of framing nail guns in four areas of the country. Sales personnel had little understanding of risks associated with use of framing nail guns. Individuals who had used the tool and those working in construction outlets were more likely to be knowledgeable; even so, less than half understood differences in trigger/actuation systems. Consumers, including contractors purchasing for workers, cannot count on receiving accurate information from sales personnel regarding risks associated with use of these tools. The attitudes and limited knowledge of some sales personnel regarding these potentially deadly tools likely contributes to a culture accepting of injury. The findings demonstrate how influences on the culture of construction are not limited to workers, employers, or the places construction gets done.

    ABSTRACT: Construction workers are frequently exposed to various types of injury-inducing hazards. A number of injury prevention interventions have been proposed, yet their effectiveness is uncertain. To assess the effects of interventions to prevent injuries in construction workers. We searched the Cochrane Injuries Group's specialised register, CENTRAL, MEDLINE, EMBASE, PsycINFO, OSH-ROM (including NIOSHTIC and HSELINE), Scopus, Web of Science and EI Compendex to September 2011. The searches were not restricted by language or publication status. The reference lists of relevant papers and reviews were also searched. Randomised controlled trials, controlled before-after (CBA) studies and interrupted time series (ITS) of all types of interventions for preventing fatal and non-fatal injuries among workers at construction sites. Two review authors independently selected studies, extracted data and assessed study quality. For ITS, we re-analysed the studies and used an initial effect, measured as the change in injury-rate in the year after the intervention, as well as a sustained effect, measured as the change in time trend before and after the intervention. Thirteen studies, 12 ITS and one CBA study met the inclusion criteria. The ITS evaluated the effects of the introduction or change of regulations (N = 7), a safety campaign (N = 2), a drug-free workplace programme (N = 1), a training programme (N = 1), and safety inspections (N = 1) on fatal and non-fatal occupational injuries. One CBA study evaluated the introduction of occupational health services such as risk assessment and health surveillance.The overall risk of bias among the included studies was high as it was uncertain for the ITS studies whether the intervention was independent from other changes and thus could be regarded as the main reason of change in the outcome.The regulatory interventions at national or branch level showed a small but significant initial and sustained increase in fatal (effect sizes of 0.79; 95% confidence interval (CI) 0.00 to 1.58) and non-fatal injuries (effect size 0.23; 95% CI 0.03 to 0.43).The safety campaign intervention resulted in a decrease in injuries at the company level but an increase at the regional level. Training interventions, inspections or the introduction of occupational health services did not result in a significant reduction of non-fatal injuries in single studies.A multifaceted drug-free workplace programme at the company level reduced non-fatal injuries in the year following implementation by -7.6 per 100 person-years (95% CI -11.2 to -4.0) and in the years thereafter by -2.0 per 100 person-years per year (95% CI -3.5 to -0.5). The vast majority of technical, human and organisational interventions that are recommended by standard texts of safety, consultants and safety courses have not been adequately evaluated. There is no evidence that introducing regulations for reducing fatal and non-fatal injuries are effective as such. There is neither evidence that regionally oriented safety campaigns, training, inspections nor the introduction of occupational health services are effective at reducing non-fatal injuries in construction companies. There is low-quality evidence that company-oriented safety interventions such as a multifaceted safety campaign and a multifaceted drug workplace programme can reduce non-fatal injuries among construction workers. Additional strategies are needed to increase the compliance of employers and workers to the safety measures that are prescribed by regulation. Continuing company-oriented interventions among management and construction workers, such as a targeted safety campaign or a drug-free workplace programme, seem to have an effect in reducing injuries in the longer term.
