Spring Ice II

Ice safety tips (from Canadian Red Cross):


Ice Factors


Many factors affect ice thickness including: type of water, location, the time of year and other environmental factors such as:


* Water depth and size of body of water.

* Currents, tides and other moving water.

* Chemicals including salt.

* Fluctuations in water levels.

* Logs, rocks and docks absorbing heat from the sun.

* Changing air temperature.

* Shock waves from vehicles traveling on the ice.


Ice Colour


The colour of ice may be an indication of its strength.


* Clear blue ice is strongest.

* White opaque or snow ice is half as strong as blue ice. Opaque ice is formed by wet snow freezing on the ice.

* Grey ice is unsafe. The grayness indicates the presence of water.


Ice thickness should be:


* 15 cm for walking or skating alone

* 20 cm for skating parties or games

* 25 cm for snowmobiles.
