Differences between External and Internal Factors of Employee Safety [Video]

April 19, 2017

Esteban Tristan, Ph.D., Director of Safety Solutions at Select International takes a moment to discuss the differences between the external and internal factors of employee safety, and why it's important for organizations to understand and focus on both to reduce at-risk behavior in the workplace.

Examples of external factors include foundational safety system components, such as PPE or policies and procedures, while the internal factors, which we refer to as SafetyDNA, focus on the unique psychological traits and abilities that consistently predict safe behavior in organizations.  These factors vary greatly across the general population, making each individual uniquely “hard-wired” for safety regardless of their experience. Years of research in Industrial and Organizational Psychology have identified four key psychological factors that impact an employee’s safety behavior.  

By balancing both the external and internal side of employee safety and understanding how these factors interact, organizations can make safety more personal and further reduce exposure to risk each and every day.

Learn more about each of these four factors below:
