(b) the interval between two consecutive rest periods does not exceed 14 hours.
Other Considerations and Limitations
322. (1) The master of a vessel shall ensure that the danger posed by the fatigue of crew members, especially those whose duties involve navigational safety and the safe and secure operation of the vessel, is taken into account when determining the scheduled hours of work and rest.
(2) Despite sections 320 and 321 and subject to subsection (1), the master may ensure that the hours of work and rest are in accordance with an applicable collective agreement that provides for hours of work and rest that are no less favourable to crew members.
(3) Sections 320 and 321 and subsection (2) do not apply when the master is conducting practice musters, fire-fighting drills or survival craft drills in accordance with regulations made under the Act if the master does so in a manner that minimizes the disturbance of rest periods and does not induce fatigue.
(4) Sections 320 and 321 and subsection (2) do not apply in respect of a crew member who is on call if the crew member has compensatory rest periods and the rest period required by those provisions is disturbed by calls to work.
(5) The master may suspend the schedule of hours of work and rest if it is necessary to do so for the immediate safety of the vessel, persons on board or the cargo, or for the purposes of giving assistance to other vessels or persons in distress at sea. As soon as feasible, the master shall ensure that every crew member who has performed work in a scheduled rest period is provided with a compensatory rest period.
