A loss-control consultant is someone who helps companies prevent bad things from happening. They help make sure that everyone is safe and nothing gets broken or lost.
It's like a grown-up who helps you not spill your milk and make sure you don't hurt yourself while playing.
The consultant looks at everything in the company to check for possible dangers like slippery floors or things that can catch on fire. They also make sure that everyone knows what to do in case of an emergency.
It's like having a superhero who keeps all the bad things away!
