A security guard is assigned to a construction site where several workers are observed handling hazardous materials without wearing the mandated Personal Protective Equipment (PPE) as outlined in the site's health and safety plan and SDSs. The guard reports this observation to the site supervisor, who dismisses the concern, stating it's a minor infraction. What is the security guard's most appropriate next course of action under the 'Internal Responsibility System' (IRS) principle in Canadian occupational health and safety legislation?

Question: A security guard is assigned to a construction site where several workers are observed handling hazardous materials without wearing the mandated Personal Protective Equipment (PPE) as outlined in the site's health and safety plan and SDSs. The guard reports this observation to the site supervisor, who dismisses the concern, stating it's a minor infraction. What is the security guard's most appropriate next course of action under the 'Internal Responsibility System' (IRS) principle in Canadian occupational health and safety legislation?

Answer options:

• Document the supervisor's response and continue patrols, as it is the supervisor's ultimate responsibility.
• Issue a verbal warning to the workers about non-compliance with PPE requirements.
• Refuse to perform duties near the hazardous materials until the situation is rectified, citing the right to refuse unsafe work. ✅ Escalate the concern to a higher level of management, the Joint Health and Safety Committee (JHSC) if applicable, or the relevant regulatory body if the risk persists and a resolution cannot be found internally.

Correct answer: Escalate the concern to a higher level of management, the Joint Health and Safety Committee (JHSC) if applicable, or the relevant regulatory body if the risk persists and a resolution cannot be found internally.

Explanation: The Internal Responsibility System (IRS) is a cornerstone of Canadian occupational health and safety legislation, placing a shared duty on all workplace parties. When direct supervisors fail to address a safety concern, the guard, as part of the IRS, has a responsibility to escalate the issue through the established workplace channels (e.g., higher management, JHSC) and, if necessary, to regulatory authorities, before exercising the right to refuse work, which is typically a last resort for direct personal danger.
