Perhaps, but such fumes rarely affect all people at the same speed; not all at once. If you're down there in the romper room and detect a strong odor and then one of your coworkers begins to become ill, are you going to stay down there sitting on your thumb until the last person keels over? All of you? Naw. I'd expect them to have enough common sense to move to safer air with only a few being affected badly enough to require a look-over.
Maybe one FA was a bit under the weather for legitimate reasons and had a good yack in his/her bunk. That could certainly set off a chain reaction, but it still doesn't explain the trip to hospital.
