Illustration SF-0020 #12 Your chemical tanker was built to the IBC Code and has foam as the main firefighting medium. During one of your safety meetings you review the properties of foam as an extinguishing agent. Which of the following is a correct statement that would be appropriate to share during the meeting? #13 You are conducting training on firefighting procedures. What type of fire is characterized by the burning of electrical equipment where the use of a non-conducting extinguishing agent is of first importance? #14 As chief engineer sailing aboard chemical tankers you frequently review the best practices regarding firefighting during safety meetings. Which of the following would align with industry best practice regarding the use of water in extinguishing chemical fires? #15 No person may serve as the person in charge of oil transfer operations on more than one vessel at a time __________. #16 The symbol shown in the illustration and used as a reference, from which the height of the center of gravity is measured, is item number __________. Illustration SF-0022 #17 As chief engineer you should understand the concept of corrective measures and their purpose. The following four actions will have which affect on the vessel? 1) Add weight low and symmetrically about the centerline. 2) Remove high weight symmetrically. 3) Move weight down symmetrically. 4) Eliminate any free surface present. #18 Prior to entering a compartment containing an atmosphere potentially dangerous to life or health and deficient in oxygen, you should don an approved breathing apparatus. Which of the listed devices would be suitable? #19 While donning the positive pressure self-contained breathing apparatus, you discover that the air cylinder pressure gage and the regulator pressure gage differ from each other by 500 psi. Which of the listed actions should you consider as appropriate? #20 As Chief Engineer your vessel has been damaged and one compartment has partially flooded. You understand that you have lost buoyancy and have added weight. If transverse stability in the flooded condition is poor or negative, every effort should be made to reduce the free surface and to lower the center of gravity. Of main importance is for you to assure which of the following is maintained? #21 Your vessel has two fire pumps and a low pressure CO2 system, which protect the cargo, holds and the engine room. A fire is reported on the #3 car deck aft hold. The emergency teams are on air. The first team reports from the forward end of the #3 car deck that there is heavy black smoke coming from the aft end of the hold and there is very limited visibility. They also report they cannot see any flames from their location. The second emergency team reports paint burning and blistering on the hull in the area of #3 car deck aft, as seen from the weather deck. How would you combat this fire? #22 Your vessel is traveling on an international voyage. Regarding the assistance of shore side firefighters to combat a vessel fire while in port, what document, if any, is required, and where would it be located? #23 While in port working cargo, a fire is reported on the forward car deck. After the captain sounds the general alarm, the crew musters and starts fighting the fire. As chief engineer you inform the captain that shore side firefighting assistance needs to be called. How would you then proceed? #24 The component shown in the illustration would be installed in which of the following types of fire detection systems? Illustration SF-0004 #25 Why is it essential to introduce CO2 from a fixed fire extinguishing system, into a large engine room, as quickly as possible? #26 Kapok life jackets require proper care and should NOT be __________. #27 The wooden shoring shown in the illustration is bearing against the hatch coaming and is supporting a load in the direction indicated by the arrows. Which of the following statements is correct for this condition? Illustration SF-0018 #28 As the senior engineer of a vessel of more than 1600 gross tons on an international voyage, you have just activated the CO2 release handle for the engine room to extinguish a fire. How would you direct the emergency team to re-enter the engine room? #29 The horizontal port or starboard movement of a vessel is called __________. #30 If a vessel initially has no list and no significant trim, which of the developments shown in the illustration will result in the greatest list? Illustration SF-0025
