Erik Rotheim
He was a chemical engineer that invented aerosol spray cans.
Spray and Wash was invented in the 1970's by Dow Chemical Company. The first Spray and Wash products were only available in aerosol cans.
The aerosol spray can was invented by Norwegian engineer Erik Rotheim in 1927. He patented the design and introduced it to the market as a convenient way to dispense products like insecticides and paints.
IMO class for aerosol spray cans is Class 2.1, which covers flammable gases. Aerosol products typically contain flammable propellants that can pose a fire hazard. Proper precautions should be taken when handling and storing aerosol spray cans to prevent accidents.
They don't have to be in a cabinet. Some people store there aerosol cans in hollowed out TV sets and some people bury them in the ground in treasure chests. I keep my aerosol spray cans in a locked box hidden in my attic, so they will never be stolen.
The value chain of aerosol cans is all about supply and demand. Aerosol cans are necessary for most jobs that require spray paint, or cleaning supplies. The value will depend on what product is being used in the cans.
No, deodorant spray cans should not be used for aerosol painting. Aerosol paints are specifically formulated for painting purposes and contain pigments and binders that adhere to surfaces. Deodorant spray cans do not contain the appropriate materials for painting and may not produce the desired results.

according to the TSA policy, no aerosol cans are allowed. It doesn't specifically say airhorns but it should be implied. i.e. spray cans, lighter fluid cans, hair spray cans.
Aerosol spray cans typically contain a propellant gas such as butane, propane, or dimethyl ether that helps to dispense the product when the valve is pressed.
Eric rotheim in 1927
Aerosol spray cans contain a propellant gas, liquid product, and a valve system. When the nozzle is pressed, the valve opens, allowing the propellant to force the liquid product out of the can as a fine mist or spray. The propellant evaporates quickly, leaving the product suspended in the air.
