In the 1-10-1 principle, what is the first "1"?
- About 1 minute to control your breathing after cold shock
- About 1 kilometre that you can swim in cold water
- One lifejacket for every 10 people on board
- About 1 hour before you start to feel the cold
显示答案
答案: A. About 1 minute to control your breathing after cold shock
Cold shock causes gasping. You have about 1 minute to calm your breathing. A lifejacket keeps your head up while you do.
第21题，共25题
In the 1-10-1 principle, what does the "10" stand for?
- About 10 hours before hypothermia
- A water temperature of 10 degrees Celsius
- About 10 minutes of useful movement
- A drift speed of 10 kilometres per hour

第22题，共25题
In the 1-10-1 principle, what is the last "1"?
- About 1 minute before you will drown without help
- Up to about 1 hour before hypothermia causes unconsciousness

- About 1 day before you will need medical treatment
显示答案
答案: B. Up to about 1 hour before hypothermia causes unconsciousness
Hypothermia takes time. It can take up to about 1 hour before you lose consciousness, so a lifejacket keeps you afloat while help arrives.
第23题，共25题
Why is sudden falling into cold water so dangerous in the first minute?
