2、ear of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the design, construction, andinstallation of intermediate portable flush deck stanch
3、ions.Intermediate stanchion is defined as any stanchion that is not anend or corner stanchion.1.2 Stanchions shall be used on interior and exterior decks,to provide temporary protection to minimize the danger ofpersonnel falling overboard or to a lower level in the ship inareas where the installatio
4、n of a fixed system would interferewith vessel operations.1.3 Stanchions may be used with38-in. (9.5-mm) galva-nized close link chain or wire rope lifelines916-in. (14-mm) topcourse,716-in. (11-mm) lower courses.1.4 This specification covers only the stanchions and doesnot cover requirements for the
5、 chain or wire rope lines to besupported by the stanchion.1.5 The values stated in inch-pound units are to be regardedas the standard.2.
