Скачать или смотреть Central Valley Fire District - December 2021 Ice Rescue Training

As we enter the first official day of winter, crews from the Central Valley Fire District have been busy training with their ice rescue techniques. Thanks to Firefighter Pitman for the great footage! Here are a few things to keep in mind as you are out and about enjoying the outdoors:

❄ You can't always tell the strength of ice simply by its look, its thickness, the temperature or whether or not it is covered with snow.
❄ Clear ice that has a bluish tint is the strongest. Ice formed by melted and refrozen snow appears milky, and is very porous and weak.
❄ Ice covered by snow always should be presumed unsafe. Snow acts like an insulating blanket and slows the freezing process. Ice under the snow will be thinner and weaker. A snowfall also can warm up and melt existing ice.
❄ If there is slush on the ice, stay off. Slush ice is only about half as strong as clear ice and indicates the ice is no longer freezing from the bottom.
