摘要

This refers to David Blossom's "Fire Pumps: The Invisible Firefighter" (August 2005). As a 15-plus-year member of the National Fire Protection Association Pamphlet 20 Committee and serving 30-plus years as a fire officer, I believe several inaccuracies in the article may lead to confusion or injury on the fireground and should be addressed. Blossom states that the Siamese connection is piped upstream of the fire pump. The actual position of the connection is downstream of the pump and on the system side of the check valve, which allows the pumper connected to the Siamese to completely bypass the fire pump and discharge directly into the connected fire suppression systems [NFPA 20, Figure A.5.19.1.2 (b)].
