Quite simple really. I don't know why I haven't thought of it before. Perhaps its because I'm not a lady.
Any old how ladies here we go.
Use old out of date discarded fire extinguishers to powder your faces, they should have powder in em, powders powder init. Just a little squirt is all that's needed, but better protect your eyes with motorcycle goggles. Just a little squirt on the nose and cheeks and rub it around a bit with something. Your face and indeed all of you if you squirt it all over will make you fire resistant, which is good and would please any BSS inspector especially chaps like Jonah Rob or the Radio mariner.
The usual size would rest inside a largish handbag nicely. So throw away those old powder puff compacts and bring yourselves up to date with the state of the art. I Kidde you not.
