Which statement describes when gas monitoring failure constitutes a dangerous situation?

• A. The failure or non-operation of gas monitoring without an SOP for portable detectors or adequate PGD
• B. Regular operation of gas monitoring with no SOP
• C. A functioning gas monitoring system with no SOP
• D. Gas monitoring is not relevant to danger

Answer: (A)

Gas monitoring is a critical safety barrier because it gives early warning of hazardous gas levels. A dangerous situation arises when that monitoring has failed or isn’t operating, and there’s no documented procedure to ensure portable detectors are in place and adequate personal gas detection (PGD) is provided. Without an SOP guiding calibration, maintenance, use of portable detectors, and the distribution and use of PGD, workers can be exposed without timely warning. So the scenario describes a failure of the monitoring system coupled with a lack of procedures to manage detectors, which is exactly what creates a dangerous situation. In contrast, regular operation without an SOP still implies a functioning system but lacks formal guidance, which is risky but does not describe a failure, and a functioning system with no SOP or a belief that gas monitoring isn’t relevant do not describe a failure scenario.
