Yes, air horns can become dangerous in hot weather, depending on the type of horn and the conditions. Rechargeable air horns, such as the WoodsCan Hornet, are much safer and more reliable than disposable aerosol canister air horns. Here’s what to know:
Aerosol Canister Air Horns (most common handheld type):
These contain a compressed gas (like HFC-134a, CO₂, or other propellants). If left in direct sun, in a car, boat, or other hot environment, the canister can over-pressurize and leak, burst, or even explode.
Rechargeable Air Horns:
Rechargeable electric air horns use a battery-driven compressor with no flammable propellants, so heat has little impact. They are much safer to use in hot environments compared to disposable gas air horns.
