A CHC contractor discovers unmarked pipes during excavation near a hospital utility tunnel. What is the correct first step?
Answer: Stop work and contact the utility owner or facility engineer to identify the lines
Work must stop immediately upon discovering unmarked utilities, and the facility engineer or utility owner must identify lines before work resumes to prevent service disruptions or injury.
Which NFPA standard governs the storage and handling of medical gases, including oxygen, in healthcare construction areas?
Answer: NFPA 99
NFPA 99, Health Care Facilities Code, governs medical gas systems including storage, handling, and piping in healthcare facilities.
Under the ICRA matrix, which construction activity TYPE requires the highest level of infection control precautions?
Answer: Type D — major demolition and construction requiring full barriers
Type D activities, such as major demolition, generate the most dust and require the highest ICRA precautions including full barriers, negative pressure, and HEPA filtration.
What is the primary purpose of a 'hot work permit' system on a healthcare construction project?
Answer: To control ignition sources and prevent fires during welding, cutting, and grinding
Hot work permits control open-flame and spark-producing activities by requiring safety checks, fire watch, and documentation to prevent accidental fires.
A risk assessment matrix scores a hazard as 'high likelihood' and 'catastrophic severity.' Which risk response is MOST appropriate?
Answer: Immediately implement controls to reduce likelihood and severity
A high-likelihood, catastrophic-severity risk falls in the highest risk zone and demands immediate mitigation to reduce both probability and impact.
Which type of respiratory protection is required for workers performing Category 3 silica-generating tasks under OSHA's Respirable Crystalline Silica standard (29 CFR 1926.1153)?
Answer: Half-face air-purifying respirator with P100 filters
OSHA Table 1 specifies that certain silica tasks require at minimum a half-face APR with P100 filters unless engineering controls fully eliminate exposure.
When must a healthcare contractor submit an updated Infection Control Risk Assessment (ICRA) during a project?
Answer: Whenever the scope of work, construction methods, or affected risk zones change
The ICRA must be updated whenever project scope, methods, or the adjacent patient risk zones change to ensure controls remain appropriate.
