To tie up one or two unanswered queries, The fire dept asked the Captain, after taxiing off the runway, what his intentions were, either chutes or steps on, 121.6, the reply was from the Captain was that he was going to use steps.
To question the airports emergency procedure with regarding one set of steps may be a little premature , as I saw two sets of steps taken there even though only one was used. Whoever decided not to use the other set I do not know.
The only other thing that occured was the tug going up in a puff of smoke whilst towing it to stand 80 , and having to get another one to complete the journey.
