Aerosol Can Blows Out Windshield in Terrifying Oklahoma City Heat Explosion

A dramatic video out of Oklahoma City is putting a spotlight on a hazard many drivers overlook every summer: leaving pressurized aerosol cans inside a hot car. The footage, captured on July 30 by a local auto glass company, shows a can of Berryman B-12 carburetor cleaner that exploded from extreme heat, its ruptured shell left lodged directly in the shattered windshield of a parked vehicle. The force of the blast was strong enough to blow a hole straight through the glass, offering a stark visual warning of just how violent these ruptures can be.

The explosion illustrates a physical reality that catches far too many drivers off guard. On a hot summer day, the interior of a parked car can rapidly climb past 140 degrees Fahrenheit, even when outside temperatures feel merely warm. That kind of heat causes the pressure inside sealed aerosol cans to build rapidly, and once the can's structural limits are exceeded, the result is a sudden, forceful rupture capable of shattering glass and sending metal fragments flying. Products like carburetor cleaner, spray paint, and other pressurized automotive or household items are especially vulnerable given their common use and frequent storage inside vehicles.

Safety experts are using the incident as a timely reminder for drivers to think twice before leaving aerosol products in their cars during hot weather, particularly as temperatures continue to climb across much of the country. Simple precautions, such as storing these items indoors or in an insulated container, can prevent a similar explosion from turning into a much more dangerous situation involving injury. As this Oklahoma City video makes clear, what seems like a minor convenience of leaving a can in the car can escalate into a genuine safety hazard in a matter of minutes.
