Safe-T-Alert Marine Gas Fume Leak Detector

The Safe-T-Alert Marine Gas Fume Detector is a two-part alarm with a remote sensor for the bilge or engine compartment, watching for gasoline and propane leaks.

Gasoline vapor and propane are both heavier than air, so a leak settles into the lowest part of the boat rather than dispersing. That is what makes a boat different from a house and why the sensor mounts low. By the time a leak is smelled at head height, the bilge is already holding an explosive concentration.

The display installs in the galley or at the helm while the sensor stays in the bilge, so the alarm sounds where people are rather than where the gas is. It monitors during and after fueling, which is the window when vapor accumulates fastest and when most incidents occur. Explore more gas and carbon monoxide detectors.

• Gasoline and propane vapor sink to the bilge
• Smelling it at head height means the bilge is already dangerous
• Display at the helm or galley, sensor in the bilge
• Monitors during and after fueling
