My wife left our fire extinguisher in the washing machine, should I be concerned?

My wife just told me when she went to throw the laundry into the dryer she found our fire extinguisher. Should the machine be okay? It went through the entire cycle and things seem okay, but I'm thinking the extinguisher won't work now.

Edit: This seems to be getting more attention then I thought. She's 37 weeks pregnant and blaming it on brain fog, lol. I was just curious if it might explode now.
