The acgih guidelines and consensus standards criteria are typically recommended when there is no osha criteria addressing a particular problem.
Restrict access for anyone with asthma allergies and respiratory illnesses.
Additionally vs 75 04 allows the designer to further reduce the airflow rate to 50 cfm ft 2 when the cross sectional area in a drive through booth is greater than 150 ft 2.
