Question 1 of 15
What is the risk of frostbite at Windchill Temperature -28 to -39° C?
Correct - Windchill Temperature -28 to -39° C - Risk of frostbite: Increased risk, exposed skin can freeze in 10 to 30 minutes.
Incorrect - You should review the Windchill Effect section.
Question 2 of 15
When does hypothermia become fatal?
Correct - Hypothermia can lead to coma or death if the body temperature falls below 32° C.
Incorrect - You should review the Hazards and Effects of Cold Working Environments on the Human Body section.
Question 3 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 4 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 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
At what body temperature does someone show the first sign of hypothermia?
Correct - Signs of hypothermia can arise at a body temperature of 35–36°C.
Incorrect - You should review the Hazards and Effects of Cold Working Environments on the Human Body section.
Question 7 of 15
What are the signs of Windchill?
Correct - As the speed of the wind increases, it can carry heat away from your body much more quickly, causing skin temperature to drop. Watch out for these signs: constant severe shivering, slow reaction, tiredness, confusion and nausea, blue, pale and cold skin, breathing and heart rates become slower, and loss of consciousness.
Incorrect - You should review the Windchill Effect section.
Question 8 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 9 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 10 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 11 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 12 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 13 of 15
What is Windchill?
Correct - Windchill is the temperature your body feels when air temperature and wind speed are combined.
Incorrect - You should review the Windchill Effect section.
Question 14 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 15 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.
