What is the 5i Psychological Health and Safety® Methodology?

The 5i Psychological Health and Safety® (5i PHS^TM)is a proprietary methodology developed by EHS Compliance Services Inc. (EHSCSI) to help organizations systematically reduce the risk of psychological harm in the workplace. Rooted in the Plan-Do-Check-Act cycle that underpins international standards like ISO 14001 and ISO 45001, the 5i PHS^TM Methodology provides a structured, holistic approach to psychological health and safety, supporting continuous improvement and a positive organizational culture.

Below, we break down each of the five “I’s” that form the backbone of this methodology.

Increase Competence

The journey starts with building awareness and knowledge. Most employees lack the training to identify psychosocial hazards, as psychoeducation has not historically been part of standard workplace training. The 5i PHS^TM Methodology addresses this gap by providing awareness and literacy training, equipping employees with the vocabulary and understanding necessary to recognize psychological hazards and psychosocial factors in their work environment.

Identify Hazards and Risks

Once employees are equipped with foundational knowledge, the next step is to identify the specific hazards and risks present in the workplace. This includes both physical and psychosocial factors across four key areas:

• How work is organized
• Workplace social factors
• The work environment itself
• Hazardous equipment and tasks

By systematically assessing these areas, organizations can pinpoint factors that significantly impact employee well-being and organizational culture.

Improve the Risk Profile

After hazards and risks are identified, they are analyzed and prioritized. This evaluation results in a risk profile that highlights which issues need immediate attention. With the recommendations and guidance of our experts, organizations can then implement targeted risk mitigation options, ensuring that resources are focused on the most significant threats to psychological health and safety.

Implement Controls

Targeted actions are implemented to reduce or eliminate identified risks, with priority given to organizational and work design interventions. This includes changes to workload, staffing, processes, role clarity, supervision, and other system-level factors that influence psychosocial exposure.

Integrate Support Systems

Systems are established and strengthened to support workers when psychosocial risks manifest. This includes access to psychological support, leadership support structures, crisis response mechanisms, and other resources that promote recovery, resilience, and sustained well-being. 

These supports complement, but do not replace, upstream risk control measures. 

Conclusion

The 5i PHS^TM Methodology offers a comprehensive, systematic approach to psychological health and safety, helping organizations protect their workers, enhance their culture, and reduce operational risks.
