Introduction

The measurement of safety performance is a hot topic in most companies today. Safety performance measurements seek to answer such questions as how do we compare to others? Are we getting better or worse over time? Is our management of safety effective (doing the right things)? Safety differs from many areas measured by managers because success results in the absence of an outcome (injuries or ill health) rather than a presence. As the scope of safety is vast, many stakeholders who are not safety professionals do not see safety as in such a broad way. They see “no injury” as good and “injury” as bad and that where it ends. This is one reason why incident rates and worker’s compensations costs have moved their way to the forefront of safety metrics. As an employee of a Facilities Engineering Command (a federal agency), working in the Operations Division, my role as an analyst requires me to gather and review metrics. Our safety metrics are very important to our organization as the safety and health program is dedicated to establishing a safety conscious culture throughout the command, ensuring that safe facilities are designed and constructed, ensuring that facilities and equipment are maintained in a safe, operating condition, eliminating facility, public works, and contact-related injuries and illnesses.

Everything changes. Our work environments, our perceptions of what is needed at work and our outlook on safety all seem to be in a constant state of change, (irony intended!). Why is there still such a thing as a worksite accident? I mean who wants to work unsafe? I cannot imagine a sane person that gets up in the morning and starts the day by thinking, “I am going to place myself in a situation that could possibly cause serious injury to me or even death”. Yet, there are such occurrences every day even though the business environment and the litigious world that we all live in dictates that the work areas are keep safe. The world of safety itself has evolved to the point that the focus is no longer just on the hazards presented in the work spaces, but the employee’s behaviors as well. For a safe workplace, business leaders have found that it really has become a team concept and everyone is involved in that team. Even the safety professional has changed roles through this evolution. In the article The Safety Man Cometh written by Randall Mundy, the description of the changes that was noticed in the…

The finding that the Culture of Safety positively relates to the client’s perception of the operational and financial performance of a project is consistent with the literature finding of the unintended positive impacts of a culture of accident prevention (Mossink & de Greef, 2002). Interestingly, we found no trade-off between building a culture of safety and performance. Indeed, building a culture of safety is a low-risk, high-return strategy that during usual times improves both financial and “client grading” operational performance and even during bad times (injuries) does not hurt performance.…
