Throw-rope

Ice picks around your neck

Cell-phone in waterproof bag or case

Required

Which of the following will help you stay safe during any on-ice activity? (choose six) *

6 points

Avoid sampling alone

Dig a test hole to measure ice thickness at least every 150 feet

Examine the ice condition, looking for holes, pressure ridges, slushy or open areas

Check your calendar to make sure the ice was safe at this time last year

Check the weather to make sure its been "pretty cold" for "a bit"

Have an accessible ice safety kit

Have an accessible general-purpose winter survival kit

Tell someone (who isn't coming with you) where you are going and when you expect to return

Required

Which of the following will help you stay safe while driving on ice? (choose four) *

4 points

Only drive on ice at night when the air temperature is colder

Wear a life jacket while in your vehicle

Check ice conditions and thickness (by drilling a hole) prior to driving or moving a vehicle on ice.

Move vehicles every two hours to prevent the sheet from sinking

Drill a hole in the ice near where a vehicle is parked. Move the vehicle if water is pooling above the hole, indicating that the sheet is sinking

Make sure the doors and windows of your vehicle are closed and locked so that it will float longer if it falls through

Open a window and unlock your doors for easy exit if a vehicle starts to sink

Fasten your seatbelt to protect you if there is a collision.

Required

How thick of an ice sheet can form in a 48 hour period at -5 degrees Celsius? *

1 point

3 cm

6 cm

48 cm (1 cm/hour)

Too many factors influence ice formation to reliably estimate ice thickness from air temperature. Test holes are required for assessment.

1 cm

Other:

Which of the following influence rate of ice formation? (Choose 10) *

10 points

Salinity of the water body

Air temperature

Sun exposure on the ice or water surface

Water currents

Snow falling into open water

Snow on top of the ice sheet

Proximity to shore

Lake depth

Water level fluctuations

Wind conditions before and after freezing

Required

If you fall through the ice, what should you do? (choose 8, in order) *

8 points

Stay calm, stay afloat, and wait for the cold-shock response to pass

Call for help

Turn around to face the ice you were standing on before you fell in

With your arms on the ice and your legs close to the surface, kick yourself forwards onto the ice like a seal

Use your ice picks to get traction on the ice and while pulling yourself out

If you are with another person, have them throw you a looped rope or long object so that they can help pull you out while staying safe themselves.

Push downwards on the ice like you're climbing out of a pool

Once you are out, slide or roll to stronger ice without standing up

When you are safe, get treatment for hypothermia immediately
