Children are generally interested in stories, comics and cartoons, so if parents are good at drawing, they can draw some by themselves to educate their children about safety. Or you can make up some interesting stories yourself, so that children can listen to their stories quietly and learn the corresponding knowledge from them.
Personally, I think it will be more useful to search some videos from the Internet for children to see, make them aware of these situations, and let them know how to deal with these emergencies from cartoons.
