Which entities survey facilities for unprotected cross-connections and classify the hazard as high or low?

• A. BE and CE survey facilities and classify them as high or low hazard.
• B. CE surveys facilities only.
• C. DOE HRS surveys facilities only.
• D. BE surveys facilities only.

Answer: (A)

The essential idea here is who is responsible for identifying unprotected cross-connections and judging how hazardous they are. Both the Building Engineer (BE) and the Cross-Connection Engineer (CE) carry out the survey of facilities to detect any unprotected cross-connections and then classify the hazard level as high or low. This paired role ensures that every facility is checked and that the hazard ranking is consistent, which directs appropriate corrective actions and prioritizes remediation.

Why this pairing is the best fit: surveying and hazard classification go hand in hand. If only one role were doing the survey, important perspectives or expertise might be missed, and if the hazard level isn’t consistently assigned, actions could be misprioritized. The other options either isolate the survey to a single role or refer to a program not aligned with standard cross-connection surveillance practice, so they don’t reliably cover both identification and hazard rating.
