Take samples from the fuel tank and test them every time tanks are filled.

Don't site buildings where there have been floods in the past 500 years
and don't site buildings downstream from dams. If a waterproof building is
built in a flood area, make sure that snorkles rise above the 500 year
flood level.

Is there any way to protect against lightning?

When siting a diesel exhaust system make sure that there are no trees,
towers or similar things nearby that could fall on it. If in a hurricane
area, reinforce diesel snorkels and arrange for multiple paths to get air
in.

anecdotes. Thus we make the network more reliable one step at a time.
