A fuel-delivery truck carries a DOT-406 cargo tank. What is the tank's maximum allowable working pressure (MAWP)?
Correct answer: A pressure of 4 psi.
Answer options
- AA pressure of 100 psi
- BA pressure of 25 psi
- CA pressure of 4 psi Correct
Why
DOT-406 tanks are low-pressure vessels, the usual choice for gasoline and other fuels, and their maximum allowable working pressure is just 4 psi. Much higher ratings belong to other tank types, such as those built for compressed gases like propane.
