6.Consider whether it's possible to signal for help.

　　If you're in a lifeboat, it should be equipped with rescue flares; read the instructions and deploy them. Be prepared to let off more flares or smoke when you are sure potential rescuers are near, to help them to pinpointyour location. Only use flares and smoke when boats or rescuers are in sight.—You don't want to waste these precious resources.

　　你所在的救生艇应该配备有救援信号火焰。阅读说明书做好部署工作。确信救援人员在附近，就准备好发信号火焰或是烟雾，帮助别人锁定你们的位置。当且仅当能看到救援人员和船只的时候才发信号和点烟----你一定也不希望浪费这些珍贵资源的。
