What does continuous monitoring consist of?

• A. Frequent checks of the environment for hazards.
• B. A rapid one-time assessment.
• C. Uninterrupted checking over a specified time.
• D. Watching a location visually.

Answer: (C)

Continuous monitoring means tracking the relevant conditions constantly over a defined period, using sensors and automated data collection so there are no gaps. In explosive-process safety, this allows real-time detection of changes in temperature, pressure, gas concentrations, or leaks, enabling immediate, appropriate responses before a minor issue grows.

This is why the idea of uninterrupted checking over a specified time fits best: it emphasizes the ongoing, time-based nature of monitoring rather than just periodic checks, a single quick assessment, or passive visual observation. Frequent checks are repetitive but not truly continuous, a rapid one-time assessment provides only a snapshot, and watching a location visually lacks the continuous data stream that instrumentation provides.
