Okay kiddo, so you know how when we're playing with toys or doing something fun, we always have to think about what could go wrong or how we can be safe while we have fun? That's kind of like what a Hazid is.
A Hazid is like playing pretend with grown-ups who are building something important, like a house or a big building. But instead of toys, they use drawings and plans to show what they want to build. And they pretend that things could go wrong and think about how to stop those things from happening.
For example, they might pretend that a big storm could come and knock over the building they're making. So they think about how to make the building strong enough to not fall over in a storm. Or they might pretend that someone could get hurt while building the thing, so they think about how to keep everyone safe while they build.
The grown-ups doing the Hazid try to think about all the ways things could go wrong, so they can be ready for anything and make sure everyone is as safe as possible.
