A本月新建筑安全研究联盟的为期一天会议展示了项目和思想,这些项目和思想质疑施工安全的一些珍贵概念。18luck官网

One such "cherished notion" is a method used by some large contractors—and supported bydecades-old research——鼓励项目团队to strive to achieve zero injuries.

But Fred Sherratt, a faculty member in theDept. of Engineering and the Built Environment at England-based Anglia Ruskin University, told attendees在11月2日的会议上her research近年来,不受联盟资助的,表明另一方面为零。前建筑经理建议零伤害的目标与英国公司有统计有关,英国公司不如那些不受安全方案目标造成零伤害的公司。

Also coming in for questioning was the notion that total recordable injury rate records are a good way of evaluating a company's safety practices.

Providing evidence against that idea was Matthew Hallowell, executive director of the联盟,该公司成立于2019年,并于2020年进行了第一个全年运营。他描述了该联盟最重要的研究迄今为止,结论是总可录制伤害率(TRIR)在统计上无效,需要更新或更换。新利luck

That metric "is an institution in itself," Hallowell told the conference audience at the University of Colorado-Boulder, where the CSRA is headquartered and where he serves as professor of engineering. The alliance's critique of TRIR—and a follow-up study now in process—amounts to "a totally different way of thinking about safety measurement."

Such iconoclastic ideas and studies are consistent with CSRA's mission to eliminate serious construction incidents and fatalities—which have plateaued in recent years—with "transformative research and defendable science." As such, the alliance's studies involve field research and rigorous statistical modeling and analysis.

Gaining Industry Support

So far, the two-year-old safety research alliance has signed up 52 sponsors, with each committing $15,000 to fund its research. Among them are construction companies such as J.E. Dunn, Kiewit and Quanta Services. How such a scientific method will fit with other approaches is not yet clear.

Construction safety research has numerous supporters. They include studies conducted or funded by the federal National Institute of Occupational Safety & Health, CPWR-the Center for Construction Research & Training and the industry-funded Construction Industry Institute, plus other industry groups and university scholars. The alliance claims on its website that it is the "only industry-funded research group focused exclusively on advancing the science of safety," with research that "passes the rigor of scientific peer review."

Construction safety research around the world takes many forms. Two scholars, writing in最近的一个问题of the International Journal of Environmental Research and Public Health, noted that some studies in the last decade analyzed hazard perception and recognition while others looked at safety climate and the workplace environment. The largest number of published research papers in the last decade or so, the authors wrote, were concerned with safety and design.

Alliance research projects also range widely.

One study seeks to determine what kind of information a quality jobsite safety briefing needs to include in order to be effective. It suggests that the briefing take place near where the work will be done and should involve input and engagement from crew members.

But the most important study so far by the alliance is its analysis of why the TRIR metric falls short in many ways.

TRIR is generally considered the number of fatalities, lost-time injuries, and other injuries requiring treatment by a medical professional per million hours worked. It is calculated by multiplying recordable incidents x 200,000 and dividing that by the total number of hours worked.

The联盟study, called "The Statistical Invalidity of TRIR as a Measure of Safety Performance," is based on analysis of 3.6 trillion work hours of TRIR data and was unequivocal:

“分析显示,在几乎每一个实际情况中,它在统计上无效地使用Trir来比较公司,业务单位,项目或团队,”作者透露。18luck官网

The study also revealed that the occurrence of recordable injuries is almost entirely random and that "no discernible association exists between TRIR and fatalities."
