7.2.10: Propane Tanks

Overview

Above-ground propane tanks can slide, bounce, or topple during an earthquake, causing a fire hazard from a gas leak. You can reduce the fire danger by doing the following (Figure 11-15):

1. Mount the tank on a concrete pad and bolt the four legs of the tank to the pad.
2. Install flexible hose connections between the tank, the supply line, and the entrance to your house.
3. Clear the area around the tank of objects that could fall and rupture the tank or its gas supply line.
4. Tie a wrench near the shut-off valve, and make sure all family members know where it is and how to use it.

For large tanks, such as those used commercially or on a farm, install a seismic shut-off valve.
