All ventilation procedures should comply with federal, state, and local regulations. Air quality should be tested prior to
ventilating a confi ned space. A purge chart is provided on our website, www.airsystems.com, help assist in estimating the
approximate time needed to ventilate confi ned spaces. Air quality should be tested continuously during confi ned space
occupancy to ensure a stable atmosphere and worker safety because atmospheric conditions can change rapidly. Addi-
tional procedures and recommendations are available from federal, state, and local agencies.
