Permissible exposure limit

Hey there! Let me tell you about something called permissible exposure limit or PEL. PEL is a safety guideline that helps keep people safe when they work around chemicals or other harmful things.

Imagine you have a bag of candy. You can eat as much candy as you want, right? But what if I told you that eating too much candy can make you sick? That's why your mom or dad might say you can only have a few pieces of candy each day.

It's kind of like that with PEL. When people work around chemicals, there is a limit to how much of that chemical they can be exposed to without getting sick. Scientists and doctors have done lots of research to figure out what that limit is. Just like your parents setting a limit on how much candy you can have, PEL sets a limit on how much of a harmful substance workers can be around.

Now, sometimes workers have to be around chemicals or other things that can make them sick. And sometimes, even being around the PEL limit can be dangerous for some people. So, it's always a good idea to wear protective gear, like gloves, masks or suits to keep yourself safe.

So remember, PEL is like a limit on how much of a harmful substance workers can be around. Just like you can only have a limited amount of candy each day to stay healthy, workers need to stay below the PEL limit to stay safe!
