Three criteria are considered when determining the maximum and minimum airflow required for each laboratory space: The minimum safe ventilation rate for a laboratory is typically six air-changes per hour--the cooling required to offset heat generated by people, lights, equipment, and transferred through the building envelope and the exhaust required by laboratory equipment such as hoods, cabinets, or snorkels.
