Best practice--Thermometers shall be hung with a non-heat conducting material such as plastic tie-wrap or string. The ship shall install DB thermometers, at a minimum, in main machinery spaces, auxiliary machinery spaces, emergency diesel spaces and other engineering spaces containing heat sources, as well as in laundry, scullery, and galley. REF: OPNAVINST 5100.19 Series, B0204B(1).
