A safety curtain is like a giant blanket that can protect people from getting hurt. Imagine you are in a big theater watching a play. Behind the actors, there are some big and dangerous machines that move and make noise. These machines could hurt people if they got too close.
To keep everyone safe, the theater has a big curtain made of special fire-resistant material called asbestos. The curtain can be lowered down between the machines and the people watching the play. This way, if something goes wrong with the machines and they start moving too fast or too close, the curtain will protect the people watching the play.
The safety curtain is controlled by a special machine that can lower it down very quickly if there is an emergency. This makes sure that no one gets hurt, and everyone can enjoy the show safely.
So, just like a blanket keeps you warm and cozy, a safety curtain keeps people safe from the big and dangerous machines in a theater. It is an important tool to make sure that everyone can have fun and be safe at the same time.
