Which term denotes a sturdy temporary enclosure built to be in place for an extended period of time?

• A. Fire Wall
• B. Flex Duct
• C. Hard Wall System
• D. Hazardous Material

Answer: (C)

A sturdy temporary enclosure designed to stay in place for an extended period is a hard wall system. This refers to rigid panels and framing that create a stable, drywall-like barrier around a work area, capable of withstanding prolonged use, supporting reliable containment, and accommodating doors, pass-throughs, and HVAC adjustments as needed. In infection control and construction risk scenarios, such enclosures help maintain negative pressure when required, are easier to clean and disinfect, and can be reused or relocated as projects evolve. Contrast this with a fire wall, which is a permanent, fire-rated structural barrier—not intended to be temporary; flex duct, which is just ventilation tubing used with the system; and hazardous material, which describes a substance category rather than an enclosure type.
