My understanding is requirements have already been dropped in a number of fire departments due to complaints and lawsuits by women.
It's getting pretty disturbing. If I'm in a fire and can't get out and pass out from smoke inhilation I don't want someone to grab me and try to slowly drag me out I want someone who can grab me and run out.
I really hate what is being done in the name of "equality".
Edit: just to point on any changes being made would apply to men who aren't up to the task as well.
