Stated very simply, the pressure inside an aerosol can is typically around 3 to 5 times atmospheric pressure. In theory, a typical can should be designed to contain roughly 2-1/2 to 3 times its normal pressure before bursting.
From the related link below:
"An aerosol can is typically safety accredited to around 12 bar internal pressure and, allowing for use at high ambient temperature and for storage in the hold of an aircraft at low ambient pressure, safety margins limit the internal can pressure to typically 4.5 to 5 bar at STP for the surrounding environment."
A "bar" is approximately 1 atmosphere as measured at sea level. "STP" means "Standard Temperature and Pressure, which usually means 0 degrees C and 1 bar.
If a vessel is heated beyond the critical temperature of its contents, pressure increases dramatically. The critical temperature is the temperature at which a liquid must become a gas, regardless of pressure. For instance, a can of "dust remover" usually contains liquefied 1,1-Difluoroethane, the critical temperature of which is 114 °C (236F). At that temperature, the pressure of a full container of that liquid must increase to about 45 bar, which would certainly burst the can. In practice, it would burst sometime before reaching that temperature.
The pressure inside a pressurized aerosol can typically ranges from 80 to 150 pounds per square inch (psi), depending on the product. This pressure is necessary to propel the product out of the can when the valve is opened. It is important to handle pressurized aerosol cans with care to prevent accidental discharge.

Why will a container of gas explode if it is heated?
Heating a container of gas increases the pressure inside the container as the gas particles gain more kinetic energy and move faster. If the pressure exceeds the container's capacity to hold it, the container can rupture or explode. This is due to the buildup of internal pressure interacting with the container's structural integrity.
Which solution that contains less dissolved solute than the solvent can hold at a given temperature and pressure?
An unsaturated solution contains less dissolved solute than the solvent can hold at a given temperature and pressure. This means that more solute could be added to the solution without it fully dissolving.
What the function of a G clamps?
A G clamp is a type of clamp used to hold objects in place, typically for woodworking or welding. It applies pressure to securely hold the objects together while they are being worked on.
How much oxygen does an E cylinder hold?
An E cylinder typically holds around 680 liters of oxygen when filled to its working capacity at a pressure of 2,200 psi. This can vary slightly based on the manufacturer and filling pressure.
What happens on a molecular level when a latex balloon is filled with 3L of air?
When a latex balloon is filled with 3L of air, the air molecules are forced into the balloon, increasing the pressure inside. The latex material stretches to accommodate the increased volume of air, as the rubber molecules are pulled apart to allow space for the air molecules. Once filled, the pressure inside the balloon causes it to expand and hold its shape.
What is the barometric pressure within the hold of a typical commercial aircraft?
The barometric pressure within the hold of a typical commercial aircraft is typically regulated to be similar to the pressure at cruising altitude in the cabin. This helps to ensure that the cargo remains stable and safe during the flight.
How do aerosol cans explode when heated?
Any pressurized container will "explode" when heated to a high enough temperature. The gas inside expands when heated increasing the pressure inside the container until the container cannot hold it any more and fails (ruptures). The contents of the can may be a flammable liquid that is vaporized by the heat and loss of containment. This gas may ignite causing an explosion or flash fire. This is known as a BLEVE, a Boiling Liquid/Expanding Vapor Explosion. Additionally, the plastic components of the aerosol can valve can fail under high temperature, as when the can is tossed into a fire, allowing a jet of liquid to come out of the can. This may not cause the can wall to rupture, but if the product or the propellant are flammable, it can still result in a fireball.
Why pressurized aircraft has fuselage in circular cross section?
circles, spheres and cylinders hold pressure well, because the pressure is evenly distributed. There's less likelihood of a rupture in thin material.
What are aerosol sprays?
Aerosol sprays are products packaged in a pressurized container that release a fine mist when the valve is pressed. They are commonly used for dispensing products such as hairspray, deodorant, air fresheners, and cleaning products. Aerosol sprays are convenient for delivering a controlled amount of product in a fine mist form.
What are the main purpose of pressure vessels?
The main purpose of a pressure vessel is to hold gases or liquids at a pressure inside a container different to the pressure outside of the pressure vessel. Usually pressure vessels are made from steel.
What job did Erik Rotheim hold?
He was a chemical engineer that invented aerosol spray cans.
Where do electrical and deoderants have to be packed had luggage or hold luggage?
Deodorants made or gel or aerosol should be in your checked in baggage while the electrical as long as it is not liquid or aerosol or gel can be on your carry on
Why do tennis balls lose their bounce when they get wet?
A tennis ball is essentially a pressurized rubber ball covered with cloth. The rubber is not completely impermeable, however, and slowly leaks over time, just like a latex balloon eventually loses its air. Also, the rubber loses some of its elasticity, although that effect is probably negligible, inasmuch as even unused tennis balls that have been removed from their pressure pack become "dead."
Why your eardrum burst outwardly in space?
In space, there is no air pressure to balance the pressure inside your ears. If the pressure inside your ear is significantly higher than the pressure outside, it can cause your eardrum to burst outwardly. This can happen if you hold your breath and strain, as the air in your lungs builds up pressure and pushes against the eardrum.
Why does a steamy soda can implode?
The reason a soda can will implode is because it builds pressure on the inside until it cant hold anymore.
Can I bring a hard toy dog on the plane?
It will most certainly be held in a pressurized area of the hold
Spacer A container with rounded ends and constructed of heavy gauge on the top usually indicates what?
It typically indicates that the container is designed to hold pressurized contents, such as gas or liquid. The rounded ends help to withstand internal pressure, while the heavy gauge top provides additional strength to contain the pressure safely.
