Heat Load – Personnel

Welding and fabrication processes release hazardous airborne contaminants that can spread throughout a facility, increasing worker exposure and creating serious health and safety risks.

Corrosive vapors and chemical emissions can deteriorate structural steel, roofing and equipment, increasing maintenance costs, compromising building integrity and reducing asset life.

Meeting the NCC's 5% Deemed-to-Satisfy (DTS) opening-area requirement doesn't automatically ensure effective ventilation. Poorly positioned openings can restrict airflow, trap heat at roof level and leave parts of the building with inadequate air movement.
