The glass-breaker mechanism includes a sensor component and a glass-breaker component. The sensor component is installed at a low point within the driver door of a vehicle. The sensor component contains a water-soluble material that retains a spring in its compressed state so long as the water-soluble material is dry. If the vehicle is immersed in water, the water-soluble material dissolves, releasing the spring. The spring drives a pin into the end of a pressurized gas (e.g., CO2) cartridge, releasing the gas therein. The gas passes through a tube to the glass-breaker component installed upon the glass just below the top of the door to drive a spiked piston into the glass and shatter the tempered safety glass of the window.
