Orica is a company that makes special stuff that goes BOOM! They make things like explosives and chemicals that are used to help dig big holes in the ground or break up rocks so we can build roads and buildings.
But Orica is very careful with their BOOM stuff. They make sure it only goes BOOM when we want it to and where we want it to. They use special machines and computers and people who are really good at their jobs to make sure everyone stays safe while using their BOOM stuff.
So, basically Orica makes BOOM stuff that helps us build things, but they make sure the BOOM stuff only goes BOOM when we want it to and where we want it to.
