changing (n.)

[A]lso not any fires or smoking are to be allowed ; and, under no pretense whatsoever, is any lucifer match to be permitted on board ; and, to guard against the infringement of this order, the clothes with pockets in them are to be taken off in changing room, or examined before beginning the work.
