Law, codes and responsibilities at a fuel station in the United States

A fuel station sits where several sets of rules meet. Occupational health and safety law protects the workers. Fire codes control how fuel is stored and dispensed, and where the emergency shut-off goes. Environmental law controls the tanks and what happens when fuel escapes. Local bylaws and permits cover the site itself. Weights and measures rules make sure the pumps are honest. A cashier does not need to know every clause, but they should know which rules shape their job, who enforces them, and what their own duties and rights are. This lesson maps those rules for Northfield Fuel and Market.

None of the clause references in this lesson replace the current text of the law. Codes are updated every few years and local governments adopt them with changes, so the site's owner and manager should always check the edition that applies to them.

Occupational health and safety

In Montana, private employers such as Northfield Fuel and Market are covered by federal OSHA, because Montana does not run its own OSHA state plan for private workplaces. OSHA's General Duty Clause requires employers to keep the workplace free of recognized hazards likely to cause death or serious harm. Specific standards also apply, including flammable liquids (1910.106), hazard communication (1910.1200), exit routes and emergency action plans (1910.36 to 1910.38), portable fire extinguishers (1910.157), walking-working surfaces (1910.22) and first aid (1910.151). Workers have the right to a safe workplace, to information and training, to report hazards and injuries, and to file a complaint with OSHA without retaliation.

Federal OSHA does not require a safety committee at small workplaces, but Montana's workers' compensation law encourages safety programs, and many insurers offer premium credits for them. Northfield runs a monthly safety meeting led by Raj, the assistant manager, and keeps a record of it.

Fire codes: the rules for fuel

The rules for how fuel is stored and dispensed come from the fire code. Most states and cities adopt the International Fire Code, whose Chapter 23 covers motor fuel-dispensing facilities, or NFPA 1 together with NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages, which is updated every three years. Montana's State Fire Marshal adopts a statewide fire code, and the Billings Fire Department inspects and enforces it locally. The fire code covers dispenser location and protection, the emergency shut-off, hoses and nozzles, attended and unattended self-service, filling of portable containers, smoking and ignition sources, signs, fire extinguishers and storage tanks.

Two fire code requirements matter to the cashier every shift. The first is the emergency shut-off: a clearly marked switch that stops all the dispensers at once, placed where the attendant can reach it but at a safe distance from the pumps. Lesson 7 covers its placement and use. The second is the rule for attended self-service: the code requires a trained attendant on duty who can see the dispensers, communicate with customers and operate the emergency shut-off. The attendant must also be able to control the pumps, so that a pump is not left running for someone doing something dangerous.

Tanks, spills and the environment

Underground storage tanks are regulated by the federal Environmental Protection Agency under 40 CFR Part 280, usually through a state program; in Montana, the Department of Environmental Quality runs it. The rules cover tank design, leak detection, spill buckets and overfill prevention, operator training (Class A, B and C operators), inspections and records. Class C operators are the employees on site who respond to alarms and emergencies, which usually means the cashier. Releases must be reported. HSE-351 covers tanks, leak detection and spill reporting in detail; this course covers what the cashier needs to know about deliveries and overfills.

Every Northfield cashier is trained as a Class C operator before working alone: they learn what the tank alarm panel shows, how to stop the dispensers, how to use the spill kit, whom to call and when to call 911. The station keeps a record of the training, because inspectors ask for it.

Chemical hazards: fuel as a hazardous product

Gasoline and diesel are hazardous chemicals under OSHA's Hazard Communication Standard. The station must have current safety data sheets for each fuel and for the store's other hazardous products, such as windshield washer fluid, motor oil, antifreeze, propane and cleaning chemicals, and workers must be trained on the hazards and the precautions. Fuel pumped into a customer's vehicle is a consumer transaction, but the employer still has to protect workers from exposure to the fuel during spills, deliveries and maintenance (Lesson 4).

Who is responsible for what

Several parties share responsibility at a fuel station, and the boundaries matter when something goes wrong.

Customers do not work for the station, but the station is responsible for what happens on its property. The cashier cannot force a customer to follow the rules, but can refuse to authorize a pump, stop a pump, ask a customer to stop doing something dangerous, and call the police or fire department. Posted signs, such as no smoking, turn off engine and no filling of unapproved containers, are required by fire codes and also give the cashier something to point to.

Contractors who work on dispensers, tanks or electrical equipment are employers in their own right, and under OSHA's multi-employer policy more than one employer can be responsible for a hazard on a shared site. The station must coordinate with contractors, tell them about site hazards and make sure their work does not endanger workers or customers. Hot work, such as welding or cutting near fuel, needs a permit and special precautions; HSE-333 covers permit-to-work systems.

Your rights as a worker

Whatever the jurisdiction, workers at a fuel station have the same core rights. You have the right to know the hazards of your job and to be trained before you face them, which at a station means knowing the fuels, the emergency shut-off, the spill kit and what to do in a robbery before your first shift alone. You have the right to raise safety concerns and to take part in fixing them, through the safety representative, committee or meeting. And you have the right to refuse or stop work you reasonably believe is dangerous, such as being asked to clean up a large spill without training or to keep the pumps running while vapor is spreading toward a drain, without being punished for it. Use these rights by speaking up early, to your manager first; most problems at a small station are fixed in a conversation.

Workers also have duties. Follow the procedures you have been trained on, use the equipment and protective gear provided, report hazards and injuries, and do not put yourself or others at risk. A cashier who sees a hose leaking and says nothing because it is nearly the end of the shift has not met that duty, however busy the night has been.

Records the station keeps

A small station generates a surprising number of safety records, and inspectors ask for them. The program below is Leah's checklist of required and recommended records, with how often each is updated, and flags anything overdue as of an inspection date. The list and intervals are typical examples for a station like Northfield, not a legal checklist for any one place.

# Check safety records against their review intervals (illustrative list and dates).
from datetime import date
today = date(2026, 10, 15)
records = [  # name, last updated, interval in days
    ("tank inventory reconciliation", date(2026, 10, 14), 1),
    ("leak detection test results", date(2026, 9, 30), 31),
    ("fire extinguisher monthly check", date(2026, 9, 2), 31),
    ("emergency shut-off test", date(2026, 8, 10), 92),
    ("staff training records", date(2026, 6, 1), 365),
    ("safety data sheets reviewed", date(2025, 8, 20), 365),
    ("emergency plan reviewed", date(2026, 2, 1), 365),
    ("spill kit inventory", date(2026, 10, 1), 31),
]
for name, last, days in records:
    age = (today - last).days
    status = "OVERDUE" if age > days else "ok"
    print(f"{name:34}{age:>5} days old  (every {days:>3})  {status}")
print("Overdue:", sum(1 for _, last, d in records if (today - last).days > d))

tank inventory reconciliation         1 days old  (every   1)  ok
leak detection test results          15 days old  (every  31)  ok
fire extinguisher monthly check      43 days old  (every  31)  OVERDUE
emergency shut-off test              66 days old  (every  92)  ok
staff training records              136 days old  (every 365)  ok
safety data sheets reviewed         421 days old  (every 365)  OVERDUE
emergency plan reviewed             256 days old  (every 365)  ok
spill kit inventory                  14 days old  (every  31)  ok
Overdue: 2

Two records are overdue. The fire extinguisher monthly check is 43 days old, so one monthly inspection was missed, and the safety data sheet review is more than a year old, so the sheets may be out of date. Neither is dramatic, but both are the kind of finding an inspector writes up, and both are easy to fix. Leah moves the extinguisher check onto the opening checklist so it is not forgotten.

For supervisors: know who to call

Post a short list beside the till: 911 for fire, injury or a major spill; the fuel company's emergency line; the tank and dispenser service contractor; the state release reporting line; the manager's phone; and OSHA for fatalities and serious injuries, which must be reported within set times. A cashier alone at night should never have to search for a number.
