This specification covers the design, construction, and installation details of two-course (Type I) and three-course (Type II) portable intermediate flush deck stanchions that are used on interior and exterior decks to provide temporary protection and minimize the danger of personnel falling overboard or to a lower level in the ship in areas where the installation of a fixed system would interfere with vessel operations. This specification does not include the requirements for the chain or wire rope lines to be supported by the stanchion. The stanchions shall be free of weld spatters, slag splinters, sharp edges, burrs, projections, and other defects hazardous to personnel, and the deck sockets shall be hammer tested for soundness and strength.

1.3 Stanchions may be used with 3/8-in. (9.5-mm) galvanized close link chain or wire rope lifelines 9/16-in. (14-mm) top course, 7/16-in. (11-mm) lower courses.
1.4 This specification covers only the stanchions and does not cover requirements for the chain or wire rope lines to be supported by the stanchion.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
