To completely assess intoxicants or dangers, according to OSHA's standards, testing of the confined spaces should be performed at 4-foot intervals.
Forced or exhaust ventilation is suitable for confined spaces. Forced ventilation uses forced & fresh air to ventilate a confined space by displacing and diluting air, whereas exhaust ventilation uses exhaust to continuously remove contaminants at the source point.
According to the AIHA (American Industrial Hygiene Association), one air change every 3 minutes or 20 complete air changes per hour for a confined space is an acceptable practice. Ventilation of the confined space also depends on the product or material being ventilated from the area.
