Enclosure integrity is critical to which outcome?

• A. Improve indoor air quality
• B. Minimize heat loss
• C. Contain agent discharge
• D. Prevent smoke infiltration

Answer: (C)

Enclosure integrity is about keeping the barrier around a hazardous area solid and leak-free so contents cannot escape into adjacent spaces. The primary outcome it ensures is containment of agent discharge, preventing release to people and other areas during normal operation or an incident. If seals, doors, or penetrations fail, the agent can spread quickly, compromising safety. While good enclosure integrity can support overall safety and may indirectly influence air quality and smoke control, its core purpose is to keep the hazardous substance contained. It isn’t primarily about minimizing heat loss, which relates more to thermal performance than containment.
