CHFM Exam Dumps : Certified Health Care Facility Manager (CHFM)

In a primary-secondary chilled water system, the primary loop is constant volume, supplying chilled water from the chiller plant. The secondary loop uses variable volume pumping to match distribution system load demand efficiently.

A. Secondary loop (Correct): Where variable flow is applied.

B. Open loop: Not a recognized term in this context.

C. Primary loop: Constant flow design.

D. Cooling tower loop: Separate condenser water system, not chilled water distribution.

NFPA 13 (Standard for the Installation of Sprinkler Systems) specifies that quick-response and standard-response sprinklers shall not be mixed within the same compartment. This is to ensure uniformity in activation and discharge characteristics.

A (Compartment): Correct, all heads in a compartment must match type.

B, C, D: NFPA does not require wholesale replacement across zones, buildings, or corridors beyond the compartment.

Before performing any work on electrical or mechanical equipment, OSHA and NFPA 70E require lockout/tagout (LOTO) procedures to isolate energy sources. This ensures the safety of workers and prevents accidental energization. Only after lockout/tagout can guards be removed, wiring disconnected, or diagnostic tests performed.
