Field notes

What to record at the tank

  1. 01

    Photograph the manufacturer label without moving piping or fittings.

  2. 02

    Measure overall length, width, and tank-body height - not leg or fitting height.

  3. 03

    Note whether the obround steel tank is standing on its end or lying on its side.

Route-specific question

One distinction that matters

Can dimensions alone prove the exact tank model?

No. Shared dimensions are common. Use the manufacturer label and model number as the deciding evidence.
