Why Is It Dangerous To Carry Aerosols In Checked Baggage

So long we know that in an ordinary situation aerosol don’t blast until it remains intact and not leaked. But there are some issues, such as pierced bottle, defective valve and excessive heat and pressure built inside can make an unavoidable accident. It could be worst if it blasts near the fire and can burn adjacent workers and spilling on them with a flake of steel. As an example, if you left an aerosol bottle in a hot car or direct sunlight can also cause a flare-up. But when it packed well and the temperature in the aircraft is controlled then bringing aerosols are quite safe.

Nevertheless, you had better know that aerosols alone are not the cause of an accident cause they don’t blow the fire on its own. For example, if electronics with batteries packed next to the aerosol inside checked baggage then batteries may overheat with temperature and could increase the pressure in the aerosol until there is an explosion. For this reason, laptops and batteries are not allowed in checked baggage. Occasionally some accidents may occur due to aircraft decompression. When we travel by plane, if we have a packet of chips in hand, it expands due to low pressure, but it is not enough to burst.

Just to remind you, if you want, you will be allowed to enter the cabin with aerosol inside the handbag, but the size of the bottle should not be more than 3.4 ounces (100 ml). These need to be packed in clear plastic bags.

Why Won’t Aerosols Explode in a Plane’s Baggage Hold?

This is because a can of this type will absorb a lot of energy before it actually does explode due to the pressure that is holding the liquid in place. The same pressure also makes sure that any shrapnel thrown out is not powerful enough to cause any serious damage. Aerosol cans have nitrogen gas let into them when they are manufactured to fill up any empty space that is left in the can when the product is being put inside under pressure. 

This means that any compression within the hold will not cause an aerosol can to explode because there is no oxygen available for combustion which makes up most of the space in a baggage hold.  Even if it were to get hot enough for some of the liquid to evaporate and create a flammable mixture, the evaporated gas is not going to accumulate easily in a baggage area.

The can may explode if it is exposed to a high enough amount of heat, the pressure inside the can build up until the weakest link breaks. This usually isn’t an issue though because there are no naked flames on planes or other heat sources which are intense enough to cause this. The only real risk of a can be exploding is if a naked flame or something that’s hot enough comes into contact with it which isn’t likely to happen.
