What safety knowledge do second graders have?

Second grade safety knowledge includes traffic safety, drowning prevention, and food hygiene.

1. Traffic safety

Pedestrians must walk on the sidewalk and walk on the right when there is no sidewalk; when crossing the road, they must use a crosswalk. When passing a sidewalk controlled by traffic signals, stop when the light is red and go when the light is green; when passing a sidewalk without traffic signals, look left and right, pay attention to passing vehicles, and do not chase or run.

If there is no pedestrian crossing, you must go straight through, and you are not allowed to cross suddenly when a vehicle approaches. If there is a pedestrian overpass or underpass, you must use the pedestrian overpass or underpass. It is not allowed to climb over the guardrails and isolation fences on the side of the road or in the middle of the road. It is not allowed to pick up cars, chase cars, forcibly stop cars or throw objects at cars on the road. Do not play, sit or lie on the road or engage in other behaviors that impede traffic.

Do not swim in rivers and lakes with unknown water conditions, and do not go out for swimming in bad weather. Swimming and playing in the water are strictly prohibited in waters with warning signs such as "No swimming or dangerous water depth". Do not run or chase around the pool to avoid slipping and injury. When swimming and playing in the water, do not push others into the water to avoid suffocation due to choking in water.
