• A. Notify local authorities
• B. Review the situation and determine the cause
• C. Conduct a full evacuation of the area
• D. Replace all safety equipment

Answer: (B)

After repairing a small chlorine gas leak, it is essential to review the situation and determine the cause. This step is critical because understanding what led to the leak is necessary to prevent future occurrences and to ensure the safety of personnel and the surrounding environment. Conducting a thorough assessment allows the operator to identify any weaknesses in equipment, procedures, or safety protocols.

By pinpointing the cause of the leak, corrective actions can be implemented, whether through improved maintenance, staff training, or enhancements to existing safety measures. This proactive approach to addressing the root cause not only safeguards against potential hazards in the future but also reinforces the importance of vigilance and continuous improvement in safety protocols within water treatment facilities.

While notifying local authorities, evacuating the area, or replacing safety equipment might be appropriate in certain situations, they do not address the immediate need to analyze and understand the underlying issues that resulted in the leak. Therefore, the review process is foundational to effective incident management and safety overall.
