How to Document a Propane Leak Check
How to Document a Propane Leak Check
A propane leak check is the test a tech runs before gas goes back on after service was interrupted. The work is the test. The record is the dated proof that the test happened — who did it, where, and what they saw. TankSpotter captures that on the phone at the tank. Check the current code text for the exact rule in the edition your state has adopted.

- The trade name is leak check, not a pressure test and not a tank-level reading.
- The record needs a person, a place, a time, and what was found — paper loses that trail.
- NFPA 54 and NFPA 58 are the code names shops already use. Read the current text. Do not trust a web page for clause numbers.
- TankSpotter is the field form, not a substitute for the code book.
What is a leak check, in shop language?
A leak check is the test for leakage after gas service was interrupted. Techs already know the job. The word in the trade is leak check, not "leak test" and not a tank-monitor ping. It is not a pressure test of the whole system unless your procedure says so. If your shop's written procedure uses different steps, follow that procedure and the code your state has adopted.
This page will not invent the steps. Steps change by edition and by state. What does not change is the need for a record that the check was done, by whom, and on which system.
When does a leak check usually get asked for?
It gets asked for after the gas was off. Out of gas, a tank swap, a new set, a line opened, a regulator changed — those are the days the office later has to prove the system was checked before it was lit. The test almost always gets done. The paper is what disappears.
When a fire marshal, a carrier, or a lawyer asks, they are not asking whether your people know how to check. They are asking for the file. "That is our practice" is a weaker answer than a dated record with a photo.
If you need the broader job of a tank inspection app, not only this form, start at what a propane tank inspection app is.
What should the leak-check record hold?
Hold enough that a stranger can tell the story without calling the tech who left last year.
- Which site and which system. - Why the gas was off, in plain words. - Who ran the check, with a signature. - When, from the device, not from memory. - A photo of the relevant equipment if your form calls for one. - Pass, fail, or what was fixed before the gas went back on.
A half-done form is not a record. Required fields exist so a blank line cannot walk out the door. Paper allows blanks. An app can refuse them.
How does an app capture that in the field?
The tech opens the leak-check form at the tank or at the meter, not later in the truck. They fill the reason, take the photo, sign, and save. If there is no signal, the phone keeps the record and sends it when a bar returns.
TankSpotter does that job inside the same app that holds tank inspections and other digital forms. Form 4 is the forms module. Safety is the safety pillar. Setup still means your form, your fields — a real pass, not a generic screen your techs will skip.
This is not tank monitoring. The app does not watch the system after the tech leaves. It records the check the tech just ran.
How does this tie to NFPA 54 and NFPA 58?
NFPA 54 is the National Fuel Gas Code. Shops use it for piping, appliances, and the leak check after an interruption of service. NFPA 58 is the LP-Gas Code. Shops use it for tanks, cylinders, and LP-gas equipment. TankSpotter's own pages already name both codes. This page will not print a clause number.
Codes are edition-specific. States adopt different years. A numbered cite copied from a blog will be wrong in some states the day it ships. Check the current code text — the edition your authority having jurisdiction has adopted — before you write a procedure or train a new hire off a vendor page.
Cylinder work has a federal layer too. Requalification rules live in 49 CFR. Our comparison of paper logs already cites 49 CFR 180.209(c) for 4-series cylinder tare-weight requalification on TankSpotter vs. paper inspection logs. Confirm that against the current 49 CFR text. Do not treat this paragraph as the rule.
Where do those records live after the truck is back?
They should live on the asset, next to the other inspection history, not in a glove box and not in a camera roll. The office should be able to filter by date, by tech, and by site, then export. That is the file you hand over.
TankSpotter keeps the field record in one system with the rest of the safety file. It does not replace your back office. It does not mail a duty-to-warn brochure — that is a separate service described on Duty to Warn. Leak-check proof and an annual safety mailing are different jobs. Do not mix them.

What this page will not claim
This page will not tell you that software makes you compliant. Software stores the work your people did. Your people still have to do the work, and you still have to follow the code.
This page will not quote a death count, a fire count, or a time-saved number. Those claims need a source URL sitting next to them. It will not name customers, awards, or carriers as proof. It will not sell TankSpotter as a tank monitor.
If you want to see the leak-check form on a phone, book a Demo or call 610-228-0887. Ask us to run it with the signal off.
