Safety Comes First

With the dynamic nature of the construction industry, R. B. Hash & Associates, Inc. uses a variety of resources to maintain a safety-first mindset. One of those resources includes our proud membership in a Captive Insurance program. As a member, R. B. Hash must maintain a strict safety culture and be held to a higher safety standard. In addition, Captive members undergo random, monthly project site safety audits, conducted by a third-party safety consultant. These inspections ensure a higher level of safety is maintained, while mitigating risk. As a member, R. B. Hash is also required to have an in-house Safety Manager who performs weekly safety audits of our project sites. Our Safety Manager is proactive in communicating our safety standards to all parties involved in a project. Since being a member, R. B. Hash’s EMR has fallen to a .63, allowing us to participate in a broader range of projects.
