Exhaust discharge air shall not be exhausted into an _________ or crawl space.

Exhaust discharge air should not be directed into an attic because attics are typically closed spaces that can trap air. This can lead to the accumulation of moisture, odors, and contaminants, creating an unhealthy environment. Furthermore, if exhaust air containing volatile organic compounds (VOCs) or other pollutants is released into the attic, these harmful substances can eventually migrate into living spaces of the building, compromising indoor air quality.

Proper ventilation is crucial, and it is essential for exhaust air to be expelled outdoors in a safe manner to avoid potential health and safety hazards. Attics are often poorly ventilated, which exacerbates the issue by allowing stale air to linger. In contrast, designated outdoor areas or properly ventilated zones are safer for exhaust discharge, as they ensure that harmful byproducts are dispersed effectively.
