15. Ships navigating through an active Ice Control Zone should take the following precautions to prevent ice damage and minimize the risk of polluting the marine environment;
(i) should proceed at moderate speed having due regard to visibility and prevailing ice conditions, and taking into account the possibility of collision with random ice in open water;
(ii) have two searchlights mounted for night time navigation;
(iii) obtain current ice information and a recommended route to follow in the event their intended route crosses an active Ice Control Zone.
16. Ice information, prognostic ice charts and recommended routing information may be received by facsimile or other communications equipment. Refer to Part 4 General Procedures, Services and systems and Part 5 Environment Canada’s Marine and Ice Warning Forecast Programs of the publication Radio Aids to Marine Navigation (RAMN) for additional information.
17. All requests for Coast Guard icebreaker escort should be arranged by the master, the owner, or the agent on his behalf, by contacting the appropriate regional Coast Guard Ice Operations Centre, or the nearest Marine Communications and Traffic Services ( MCTS ) Centre.
18. Guidance on the design and construction of sea inlets under slush ice conditions is shown in Appendix B.
19. Between mid-December and mid-March, ambient air temperatures can reach minus 40 degrees Celsius. Recommended loading practice should specify an upper limit to the temperature of cargo being loaded in order to minimize the effect of thermal shock to the ship's structure.
