      <subfield code="a">Push-pull couplings can carry liquids or gases safely in a plant if workers know how to operate and care for these devices. The safety specialist should be acquanted with the chemical compatibility of each hose and coupling material for the fluid the line will carry. This paper reports proper care required; maintaining couplings; hose handling hints; new developments</subfield>
