RULE 301.

(a) No cargo shall be hoisted from a hatch until hatch covers and strongbacks are off and stowed clear of working gear, except such cargo that must be removed to clear beams.

(b) Strongbacks and hatch covers shall be stowed so as not to interfere with a safe walkway for Hatchtenders from rail of hatch coaming to the vessel's side and so that loads or gear cannot tip same into hatches or overside.

(c) Foremen or Hatchtenders shall personally supervise the removal and replacement of hatch covers, strongbacks and beams.

(d) Idle open foc'scle hatches should be either closed, covered, fenced or their approaches locked. A "foc'scle hatch" is one on the same level as the main deck but enclosed in a compartment with a main hatch opening one deck above.

(e) Folding type hatch lids must be secured when left in partially or fully opened position.
