AHA Updated CHFM Exam Questions and Answers by finnley

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.

The Joint Commission (TJC) aligns with NFPA 101: Life Safety Code. For business occupancies (such as outpatient clinics), the requirement is that fire drills be conducted annually (every 12 months).

Quarterly (every 3 months) drills are required for healthcare occupancies (hospitals, nursing care).

Outpatient business occupancies are less stringent.

The primary cause of change orders is incomplete or unclear plans and specifications. Ensuring that drawings and specs are fully developed before bidding reduces ambiguity, scope gaps, and the likelihood of modifications during construction.

A (Correct): Complete plans/specs = fewer change orders.

B: Bonds/policies protect financially but do not reduce change orders.

C: Prequalification ensures capable bidders but doesn’t eliminate scope issues.

D: Competent managers/subcontractors help but cannot offset incomplete design docs.

Per NFPA 13: Standard for the Installation of Sprinkler Systems, 18 inches of clearance must be maintained below sprinkler deflectors to ensure proper spray pattern and fire suppression coverage.

C. 18 (Correct).

Less than 18 inches (12 or 15) is insufficient clearance.

More than 18 (24 inches) exceeds the standard, not required.
