NFPA 58 in plain English: what the LP-Gas Code asks of a propane dealer

By Bill Stomp, Founder/Editor

NFPA 58 is the Liquefied Petroleum Gas Code. It is the U.S. rulebook for storing, handling, moving and using propane, published by the National Fire Protection Association. It becomes law where your state adopts it, at the edition it picks. The current edition is 2024. For a dealer, it means written programs and records an inspector can ask to see.

From the publisher: Propane Safety Pro wrote this guide. We and our sister company Tank Spotter sell the manuals, services and software it links to. The code explanations are our own summary. The section numbers are there so you can check every point against your own copy of NFPA 58.

On January 1, 2027, federal pipeline-safety rules stop pointing at the 2020 edition of NFPA 58 and start pointing at the 2024 edition. For most propane dealers, that date changes very little. The edition that governs your bobtails, your plant and your customer installs is the one your state adopted. In two neighboring New England states, those answers sit a full revision cycle apart.

That is the first thing to know about NFPA 58. The book is national. The rules you answer to depend on your state. This guide explains the code in our own words, points to the section numbers that matter, and names the written programs an inspector will ask to see. It does not reproduce the code. NFPA owns the copyright, so the exact wording lives in your copy of the book.

Is NFPA 58 the law?

Only where a government adopts it. Most states do that the long way around. They adopt a base fire code, either NFPA 1 or an edition of the International Fire Code. That base code pulls in NFPA 58 at a named edition. Change the base code and the propane rules change under it, often with no separate notice. Other states adopt NFPA 58 through a propane agency's own rules, sometimes with changes. Texas, for one, adopts it through the Railroad Commission and layers state changes on top.

The person who enforces it is the authority having jurisdiction, or AHJ. Depending on the state, that could be the state fire marshal, a state propane or agriculture department, or the local fire official. North Carolina's Department of Agriculture, for example, inspects bulk plants against a checklist keyed to 2024-edition section numbers.

Two federal agencies also point to the code. PHMSA's pipeline-safety rule (49 CFR 192.11) uses it for propane systems that feed a distribution pipeline. That is a narrow slice of the business. OSHA has its own propane storage and handling standard at 29 CFR 1910.110.

The five things an inspector expects a dealer to have on paper

An inspector checks the code against the documents that prove you follow it. These five come up most, with the rule behind each one. The first four come from NFPA 58. The fifth comes from federal DOT rules.

1. Trained people, and the record to prove it (Section 4.4)

Section 4.4, Qualification of Personnel, says anyone whose work falls under the code must be trained for that work. That means drivers, plant operators, cylinder fillers, installers and service techs. The 2020 edition sets refresher training at no more than three years (4.4.3). Transfers carry their own people rule. At least one qualified person has to stay with a liquid transfer from hookup until it's done (7.2.1.2 in the 2020 edition).

An inspector or insurer looks for four things on every person: who was trained, on what, when, and by whom. Tank Spotter, a phone app from our sister company, keeps those training records and renewal dates in one place. The industry's standard course is moving from CETP to PERC's newer PEP program, and that changes what the record looks like. Our CETP and PEP training page explains the switch. Propane Safety Pro does not teach classes at your site. We connect dealers with training partners who do. The training policy itself belongs in your policies and procedures manual.

2. Written operating and maintenance procedures (Chapter 15)

Chapter 15, Operations and Maintenance, is where the code asks for procedures in writing. Bulk plants and industrial plants need written operating procedures and written maintenance procedures. North Carolina's 2024 inspection sheet lists them as sections 15.2 through 15.5 (operating) and 15.6 through 15.7 (maintenance). Missouri's Propane Safety Commission puts it plainly: keep the instructions at the plant they describe, keep them current, and keep them for the life of that plant.

Maintenance leaves a paper trail. Emergency shutoff valves, for one, get a function test every year, and the code wants the results written down (6.14.10 in 2020, 6.15.10 in 2024). A plant without those records has a hard time proving the test happened.

That is the job of an operations and maintenance manual written for your plant, with the section numbers cited.

3. A Fire Safety Analysis (6.29.3 in 2020, 6.30.3 in 2024)

A propane site with more than 4,000 gallons of total water capacity needs a written Fire Safety Analysis, or FSA. It looks at the whole product-control system: the emergency shutoff valves, the internal valves that close remotely or on heat, and how the site would hold up if a fire started nearby. Under the 2024 edition, the owner or operator sends it to the AHJ and to local emergency responders. It gets redone when storage capacity or the transfer system changes.

If the analysis finds an exposure the standard protections don't cover, the code calls for special protection, such as water spray or insulation (6.30.5 in 2024). PERC and NPGA publish a Fire Safety Analysis manual with the standard worksheet, and plenty of dealers start there.

Many dealers would rather hand it off. Propane Safety Pro prepares your Fire Safety Analysis for your local fire official to review.

4. Emergency planning with the fire department (6.29.2 in 2020, 6.30.2 in 2024)

The code asks that planning for incidents at a plant (a release, a fire, a security breach) be worked out with local emergency response agencies. Other parts of Section 6.30 (6.29 in 2020) cover the basics responders count on when they arrive. That means access roads for fire trucks, and at least one portable dry-chemical extinguisher of 18 pounds or more at each bulk plant and dispensing point. It also means emergency controls that are clearly marked and easy to reach.

NFPA 58 never calls any of this an "emergency response plan." Some states do. Connecticut's fire code, for one, asks for a written propane emergency response plan outright. OSHA adds its own emergency action plan rule (29 CFR 1910.38). Put together, the practical answer is a written plan your crew has walked through and your fire department has seen. Our emergency action plan is built for that.

5. The truck, and the DOT security plan NFPA 58 doesn't cover

Chapter 9 covers the propane side of bobtails and transports. The truck's hazmat paperwork falls under federal DOT rules in 49 CFR. That is where a plan many dealers miss comes from: the written hazmat security plan.

The trigger is in 49 CFR 172.800(b)(3). A company needs a plan when it offers or hauls more than 3,000 liters (792 gallons) of a Division 2.1 material in a single packaging. Propane is Division 2.1. A bobtail with a normal load is well over that line.

The plan has two parts. Section 172.802(a) says it starts with an assessment of your security risks, then covers three areas:

• Personnel security: checking what job applicants tell you, for jobs that handle the product.
• Unauthorized access: keeping the wrong people away from the product and the trucks.
• En-route security: protecting a load from the yard to the customer, including any stop along the way.

Section 172.802(b) adds three more pieces:

• The senior manager in charge of the plan, named by job title.
• The security duties of each job or department, and how workers are told when part of the plan goes into effect.
• A plan for training your people under 172.704(a)(4) and (a)(5).

Those two training rules are different. Under 172.704(a)(4), every hazmat employee gets security awareness training: the security risks of hauling hazmat, and how to spot and respond to a possible threat. New hires get it within 90 days. Under 172.704(a)(5), the people who carry out your plan get in-depth security training on your own plan. That covers its goals, who is in charge, the procedures, each person's duties, and what to do if security is breached. The plan itself is reviewed at least once a year (172.802(c)).

Our explainer on DOT security plans walks through who needs one. When you're ready to have it written, Propane Safety Pro prepares a DOT hazmat security plan for your yard, trucks and routes.

One binder instead of five

Training, operating procedures, emergency planning and security all come back to one question. What does this company do, in writing, and can it show the proof? A policies and procedures manual is where those answers live together, with the edition named on every citation. The full set of Propane Safety Pro manuals is on the safety manuals page.
