In recent years, safety climate has captured the attention of companies and scientists looking to reduce accidents and injuries. A leading indicator of safety outcomes, safety climate reflects what happens when the rubber (safety decisions and protocols) meets the road (competing demands such as production and delivery deadlines). Safety Climate can be seen as an organization’s temporal “state of safety,” a snapshot of the prevailing state of safety with the organization at a discrete point in time.
Organizational safety climate and organizational safety culture are related, but distinctly different, phenomena. Safety climate is defined in the scientific literature as employees’ shared perceptions of the organization’s workplace safety policies, procedures, and practices as they relate to the value and importance of safety within the organization. Safety culture is defined as shared safety values and beliefs that interact with an organization’s structures and control systems to produce behavioral norms. Safety climate is the measurable aspect of safety culture and research indicates these measures can be used to predict safety-related outcomes (e.g., accidents and injuries) and safety behavior.
Despite what looks like a strong emphasis on safety, a company may have a poor safety climate. That means that even in organizations that have implemented safety programs and protocols, when business demands are high, safety may take a backseat to other priorities such as productivity and efficiency.
Risk managers can assess safety at a company by surveying workers about management’s commitment to and support of safety and health.
Safety climate is a leading indicator of safety outcomes and is the measurable dimension of organizational safety culture.
Companies that understand and monitor safety climate can identify where problems may lie and take appropriate steps to proactively improve safety.
Safety climate can help companies recognize and address emerging problems before accidents happen.
Practical application of the safety climate survey can help companies identify ways to make focused adjustments to safety management systems that, over time, can strengthen their safety culture.
- Safety climate has a significant impact on lone workers’ safety outcomes, such as truck drivers and utility workers. When a company has good safety climate, their employees behave more safely and have fewer workplace injuries, even when no one is monitoring/watching/looking at them (e.g., Huang et al., 2013a, 2013b).
- Supervisors or workers: who rates? Our prior data showed that supervisors consistently score safety climate higher than workers do, and that their responses are not predictive of safety outcomes (Huang et al., 2014).
- The impact of safety climate is beyond safety outcomes; when a company has good safety climate, their employees have a higher level of job satisfaction, and job engagement, and the turnover rate is lower (Huang et al., 2016).
- Two levels of safety climate (organizational level “OSC” vs. group level “GSC”) significantly interacted with one another to predict safety behavior such that if either the OSC or GSC scores were low, the other’s contribution to safety behavior became stronger. These findings suggest that OSC and GSC may function in a compensatory manner and promote safe driving behavior even when either OSC or GSC scores are low. The results of this study provide critical insight into the supplementary interaction between perceptions of OSC and GSC (Huang et al., 2017).
- Short generic safety climate scale: Using an IRT analytical approach, one prior study from the research team developed shortened versions of Zohar and Luria’s (2005) 16-item OSC and 16-item GSC scales. Specifically, 8 OSC and 11 GSC items were identified with above-average discriminating ability, and further selected 4 OSC and 4 GSC items that retained at least 30% of the original total test information. It is our expectation that these shortened safety climate scales will increase the utility of safety climate assessments in both research and practice (Huang et al., 2017).
- Relationship between safety communication and safety climate: Results of this study showed that the quality of supervisor communication about safety uniquely contributes to safety outcomes, above and beyond measures of both group-level and organization-level safety climate. The construct validity of a newly-adapted safety communication scale was demonstrated, particularly focusing on its distinctiveness from safety climate and testing a model showing that communication had both main and moderating effects on safety behavior that ultimately predicted truck drivers’ injury rates. Our findings support the need for continued attention to supervisory safety communication as an important factor by itself, as well as a contingency factor influencing how safety climate relates to safety outcomes (Huang et al., 2018).

- "The safety climate lab provides a snapshot in time from the worker’s perspective. I can’t think of a better way to provide meaningful feedback to a safety program in the works. The survey is anonymous and the report from OHSU Safety Climate Lab is comprehensive. It was refreshing to hear from the objective observers at OHSU just how healthy our safety climate is and it was inspiring to hear the actions and plans that the study generated at Fortis Construction. I’d recommend that any company, no matter what size and no matter what level of safety maturity, measure their safety climate with the OHSU team. They are the experts and they draw from a wealth of data that most of us don’t have access to. It will help your company. Be brave ...listen to the findings, and take action."

Daniel Hardy, Road Safety Portfolio Manager, United Nations System Staff College (UNSSC)
- "We have focused for too long on trying to train the driver to be safer, without considering the crucial impact of the safety climate. What I like about the safety climate approach is that it is a quantitative, peer-reviewed approach that allows for a baseline from which to measure impact. It also supports the development of targeted interventions, beyond traditional training and awareness campaigns. I very much enjoyed working with the team at OHSU, who are dedicated, professional and client-centred. Highly recommended."

Roy Ben Eliezer, Global Road Safety Coordinator, United Nations High Commissioner for Refugees (UNHCR)
- “Addressing road safety in large organizations, often times requires a number of approaches to be taken under consideration in order to evaluate the overall safety landscape and identify additional safety elements that may require further attention. The Safety Climate Survey, used as a methodological tool, has definitely enabled us to have this additional perspective, to better address road safety and safety measures, while collaborating with our colleagues in the field within this process. The OHSU team have shown remarkable dedication, professionalism, and were very committed at any given point throughout the whole process. I would definitely encourage anyone who’s looking to implement a safety climate survey within their organization, to contact the OHSU team. It was great working with them!”

- "DeWitt Construction has been on a journey the past three years to improve the safety awareness and culture of the company through the use of safety perception surveys and industry safety recognition such as the AGC-PRIDE designation. In 2020, DeWitt partnered with OHSU's Safety Climate Lab Research Team to draw from their data and analytics to evaluate DeWitt employee's perception of the company's safety efforts compared to other companies. The anonymous survey responses when evaluated and tabulated by the OHSU Research Team provided valuable insights into what DeWitt is doing well and areas for improvement. DeWitt thanks the OHSU's Safety Climate Lab personnel for their time and assistance."
