Welcome to the website where you can pass online the CES CBT CD-0285 test on the subject «Enclosed space entry, Awareness». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CES based on practical information and marine specialists experience.
CES tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.
CES tests have proven themselves as good tools for the selection and recruitment process, as well as advancing the level of knowledge of the current officers and crew. Ocean Technologies Group use various subjects for question creation, which includes:
Crowd and Crisis Management;
Integrated Navigation System (INS);
Ballast water management;
Handling and Stowage;
Vessel operation management and safety;
Marine engineering;
Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Enclosed space entry, Awareness». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Enclosed space entry, Awareness» subject includes theoretical and practical information about advanced training for work on any type of vessel. The curriculum covers the recognition and assessment of potential hazards associated with entering confined or enclosed spaces on board vessels, such as the presence of toxic gases, lack of oxygen and the risk of entrapment. Participants will learn the proper protocols and safety procedures for preparing, accessing and working within these confined areas, including the use of specialized equipment and the implementation of permit-to-work systems. Training questions will simulate real-world scenarios, allowing trainees to practice emergency response techniques and the execution of rescue operations. Upon completion of the program, sailors will possess a heightened awareness of the risks involved in enclosed space entry and the critical importance of adhering to established safety standards to protect themselves and their crew members.
On this site Crew Evaluation System Test on the subject «Enclosed space entry, Awareness» contains 30 questions you need to answer with no possibility to go back to previous question. Therefore, we recommend carefully reading each question and making decision with no hurry. In case you have some difficulty answering, you have also possibility to request a hint.

The person who appears drunk should be given plenty of water.
The person who appears drunk should be reported.
The person who appears drunk should be told to leave the space.
If you are working in an enclosed space and the attendant instructs you to leave, what should you do?
Leave the space immediately, and ensure the rest of the team does the same.
Ask for an SCBA to be brought in so that you can continue working.
Ask why work is being stopped and contact the officer of the watch.
Check your personal gas monitor.
Once an emergency team has been prepared for an enclosed space rescue, which one of these options is their first priority in most situations?
