What does periodic monitoring consist of?

• A. Frequent checks of the environment for hazards.
• B. Uninterrupted checks over a specified time.
• C. A single snapshot of conditions.
• D. Randomly timed checks.

Answer: (A)

Periodic monitoring means checking at regular, predefined intervals to detect changes in the environment that could indicate hazards. This approach is about consistency in timing, so you can track trends and catch deviations before they become dangerous. That’s why frequent checks of the environment for hazards best embody periodic monitoring.

The other options describe different ideas: continuous (uninterrupted) monitoring would be ongoing without breaks; a single snapshot is just one-time and doesn’t track changes over time; randomly timed checks lack a fixed schedule and can miss trends. Periodic monitoring sits between these, using regular, planned checks to keep conditions within safe limits.
