Who is Maryland Burglar and Fire Alarm Association ? Are they OK ?
Nope. They are specifically prohibited. See: tsa /travelers/airtravel/p and scroll down near the bottom of the page. In case you have not noticed, there are fire extinguisher locations in the overheard compartments. They are noted with a sticker on the outside of the bin. There are also probably some in the galley. So - you don't need to bring your own.
thermoplastic road marking materials are specific coatings with thermoplastic properties. Some of those are made so that the marking can endure loads, high temperatures and UV oxidation, typically characteristics from high traffic roads.
Don't be silly. For safety reasons you need to get a little helmet with a pull down visor.
