The guard consults the Safety Data Sheet (SDS) and notes that the substance has a WHMIS Pictogram for "Corrosion" and "Health Hazard." According to current Canadian WHMIS regulations, which of the following is the most immediate and critical action the guard should take once the area is secured and emergency services notified?

Question: A security guard performing duties at a chemical storage facility observes a drum leaking a corrosive substance. The guard consults the Safety Data Sheet (SDS) and notes that the substance has a WHMIS Pictogram for "Corrosion" and "Health Hazard." According to current Canadian WHMIS regulations, which of the following is the most immediate and critical action the guard should take once the area is secured and emergency services notified?

Answer options:

• Initiate a detailed internal incident report outlining the spill volume and potential environmental impact.
• Attempt to neutralize the spill using readily available absorbent materials to prevent further spread. ✅ Ensure all personnel are evacuated from the immediate and surrounding contaminated areas, strictly based on SDS information and site-specific emergency plans.
• Contact the facility manager to determine the appropriate waste disposal procedure for the spilled substance.

Correct answer: Ensure all personnel are evacuated from the immediate and surrounding contaminated areas, strictly based on SDS information and site-specific emergency plans.

Explanation: Under the Workplace Hazardous Materials Information System (WHMIS) as regulated by Health Canada, the primary focus in a hazardous spill is worker safety. The SDS and site-specific emergency plans dictate immediate evacuation to protect personnel from exposure, which takes priority over incident reporting or neutralization without proper training and equipment.
