What is Elimination? Definition and Workplace PHS Impact

Elimination in Psychological Health and Safety (PHS) is the process of physically or procedurally removing a psychosocial hazard so that the risk no longer exists. It is the most effective control because it does not rely on human behaviour, individual resilience, or protective equipment. In a PHS context, elimination means identifying a source of psychological strain —such as a toxic communication practice or a redundant high-stress process—and simply stopping it.

The impact of elimination is a permanent reduction in the organization's risk profile. When a hazard is eliminated, the need for training, monitoring, and "resilience building" related to that specific hazard disappears. This creates a safer environment by default, rather than requiring employees to navigate around known dangers.

The Standard Definition (CSA Z1003 / ISO 45003)

In the Hierarchy of Controls outlined by ISO 45003, elimination sits at the top. It is the first strategy an organization must consider before moving down to substitution or administrative controls. For a control to be considered "elimination" under these standards, it must:

• Remove the Source: It must address the root cause of the psychosocial risk (e.g., eliminating a confusing dual-reporting line).

• Be Procedural: It often involves changing the "design" of the work rather than just the "volume" of work.

• Be Primary Prevention: It aims to prevent the harm from ever occurring, rather than mitigating it after it has been identified.

Why Elimination Matters for Leaders & HR

Elimination is the gold standard for Reasonable Care. It is the most defensible action an employer can take because it removes the possibility of foreseeable harm.

1. Maximum ROI: While it may require an initial operational shift, elimination is often the cheapest long-term solution because it stops the ongoing costs of absenteeism, turnover, and disability claims associated with that hazard.

2. Reduces "Program Fatigue": Instead of adding more wellness programs to manage stress, elimination removes the stressor itself. This simplifies the workplace and improves focus.

3. Clear Accountability: It is easier to measure the success of an eliminated hazard than a mitigated one. You are either doing the harmful activity, or you are not.

How to Address Elimination in Your Organization

To achieve elimination, an organization must use their PHS-IMS to identify hazards that are "designed into" the business and can be removed through structural changes.

• Audit Communication Practices: If after-hours connectivity is identified as a hazard, a true elimination strategy is not a "well-being tip" to ignore emails; it is a technical or policy-based shutdown of the mail server or an explicit ban on sending non-emergency communications after 5 PM.

• Streamline Reporting Structures: If role conflict is a hazard, eliminate the conflict by redesigning the organizational chart to ensure every employee has one clear set of priorities and one direct supervisor.

• Address Workload at the Root: If a specific manual reporting process is causing chronic burnout, eliminate the process through automation or by determining if the data is actually necessary for business operations.

• Documentation: Record the elimination in your management system as a permanent control. This demonstrates the highest level of due diligence, showing that the organization chose to remove a risk entirely rather than asking employees to tolerate it.

Expert Insight

Elimination is the ultimate test of an organization's commitment to PHS. It requires the courage to ask, "Is this process more valuable than the mental health of the people doing it?" If the answer is no, the process is eliminated.
