The possible safety hazards in snow cleaning include: slipping and falling, frostbite at low temperature, and traffic accidents.

1. Slip and fall: When walking on the snowy ground, people easily lose their balance due to the sliding of their feet, which leads to falls and falls. For people with relatively weak physical functions such as the elderly and children, the risk is even greater. Therefore, when cleaning the snow, we should pay special attention to keep the body balanced, wear appropriate shoes and clothes, and choose anti-slip cleaning tools as much as possible.

2. Low temperature frostbite: In a low temperature environment, people's skin is vulnerable to frostbite. Cleaning the snow in a cold environment for a long time, if you don't take appropriate warm-keeping measures, such as wearing gloves, hats and thick clothes, may lead to frostbite on exposed parts such as hands and face. Therefore, when cleaning the snow, we should pay attention to keep warm and try to avoid being exposed to cold environment for a long time.

3. Traffic accidents: In the process of clearing snow, the risk of traffic accidents will increase correspondingly due to the slippery road surface and reduced visibility. Therefore, when cleaning the snow, we should pay attention to traffic safety, try to choose to clean during the day and avoid doing it in bad weather.

Precautions for traveling in snowy days:

1. Walk on snowy and icy roads, wear non-slip rubber shoes, try not to wear flat-bottomed shoes without patterns, keep warm, and always pay attention to driving conditions.

2. When it snows, the road is slippery, especially when going downhill, you must pay attention to keeping your center of gravity as low as possible when walking, and don't walk on tiptoe. It is recommended that you don't carry heavy things with one hand.

3. When it snows, people usually walk with their heads down, which often leads to terrible accidents, so everyone should try to walk away from the driveway.

4. When crossing the road, be sure to stand on the side of the road and look at the situation on the road first, especially adjust your hat, don't block your sight, and cross the road carefully when you are sure that there are no vehicles. Never rush or run, don't cross between two cars, and don't suddenly change the direction of walking or retreat.
