Question 1 of 15
When does frostbite happen?
Correct - Frostbite happens when the temperature of the skin reaches –1 °C.
Incorrect - You should review the Hazards and Effects of Cold Working Environments on the Human Body section.
Question 2 of 15
What is the best counter to cold weather?
Correct - Cold temperatures have a negative effect on human physiology. The best counter to this is to remain warm for as long as possible. The next best counter is to wear appropriate winter clothing, in layers, to remain as warm as possible.
Incorrect - You should review the Risk Assessment section.
Question 3 of 15
What control measures can be put into place when icy decks are present?
Correct - Control measures for icy decks include the use of grit or other substances to generate a grippier surface on which to walk as well as regular clearing of ice from the decks using a steam lance or other similar approved apparatus.
Incorrect - You should review the Risk Assessment section.
Question 4 of 15
How much is the insulation of the clothing decreased by then moisture is not properly drawn from the skin?
Correct - If the moisture is not properly drawn from the skin, then the insulation of the clothing is decreased by up to 50%, hence the importance of having an appropriate first layer of clothing.
Incorrect - You should review the PPE and PPC section.
Question 5 of 15
What hazards and risks can be present due to the cold environment?
Correct - The work area will be affected due to the weather, making the decks more hazardous than usual. This occurs because of the presence of ice on deck, and hence increase of slip hazards when working on the upper decks, especially when this is combined with the regular rolling and pitching of the ship when underway.
Incorrect - You should review the Risk Assessment section.
Question 6 of 15
How is the early stage of hypothermia treated?
Correct - The early stages of hypothermia must be treated by moving the person to a safe warm place, and warming them up slowly. Initial treatment upon getting a person out of water would be to cover them with a thermal protective aid.
Incorrect - You should review the Hazards and Effects of Cold Working Environments on the Human Body section.
Question 7 of 15
What should the inner layer of clothing be made of?
Correct - The inner layer should be preferably made of polyester or silk. These are materials that draw the moisture away from the skin.
Incorrect - You should review the PPE and PPC section.
Question 8 of 15
When does frostbite occur?
Correc - Frostbite occurs when your body tissues freeze.
Incorrect - You should review the Hazards and Effects of Cold Working Environments on the Human Body section.
Question 9 of 15
Is this statement true or false? Boiling water should be used to remove ice from the deck.
Correct - False. Boiling water should never be used as this may cause thermal shock to the steel and induce brittle areas in the deck.
Incorrect - You should review the Risk Assessment section.
Question 10 of 15
Is this statement true or false? While working, it is natural to sweat, with that said, it is important to never remove clothing while in an exposed environment, instead go indoors to dry off.
Correct - While working, it is natural to sweat, with that said, it is important to never remove clothing while in an exposed environment, instead go indoors to dry off.
Incorrect - You should review the PPE and PPC section.
Question 11 of 15
What should PPE be capable of in cold environments?
Correct - In such environments, safety gloves must be insulated, safety glasses should not fog up and safety shoes must protect against frostbite.
Incorrect - You should review the PPE and PPC section.
Question 12 of 15
What is recommended to avoid heating the body up quickly?
Correct - Hot drinks and a dedicated "warming room" are recommended to ensure crew members warm up slowly to avoid complications arising from heating the body too quickly.
Incorrect - You should review the Risk Assessment section.
Question 13 of 15
What is the best way to dress in cold weather?
Correct - Air trapped between layers of clothing provides greater insulation and consequently, a reduction in loss of body heat. Wool is a great material for cold weather, it breathes and can keep you warm even if it becomes wet.
Incorrect - You should review the PPE and PPC section.
Question 14 of 15
Which of the following lead to hypothermia?
Correct - Prolonged exposure to cool temperatures, even above 0° C, or falling into cold water can lead to hypothermia.
Incorrect - You should review the Hazards and Effects of Cold Working Environments on the Human Body section.
Question 15 of 15
What do the external temperatures associated with polar waters affect?
Correct - The external temperatures associated with polar waters will affect the personnel, work environment, and the ship itself.
Incorrect - You should review the Risk Assessment section.
