# Transporting Oxygen in a Vehicle: NEMT Tank Rules, Limits, and Safety

Canonical URL: https://nemtguide.com/guides/transporting-riders-with-oxygen/ · Updated 2026-09-30

Transporting oxygen in a vehicle is routine on NEMT rides when the rider brings and runs their own supply. Federal hazardous materials rules let a van carry cylinders of up to 220 pounds each and 440 pounds in all, each one secured against shifting. Drivers do not give or adjust oxygen, so a rider who needs someone to do that usually rides in an ambulance.

- You may not turn a rider away because they travel with portable oxygen (49 CFR 37.167(h)).
- A rider's oxygen rides as a material of trade: up to 220 pounds per cylinder and 440 pounds per vehicle, secured, labeled, and known to the driver.
- The rider runs the oxygen. Georgia, Virginia, and New York keep NEMT drivers and crews from giving or adjusting it.
- A rider who needs oxygen given, adjusted, or monitored by someone else goes by ambulance in Ohio and California, or with an EMT on board in New Jersey.
- No smoking, no flames, no loose tanks, and no tank left behind in a parked van.

Riders come aboard with oxygen every day: a small cylinder in a holder on the back of a wheelchair, a tank on a cart, or a battery concentrator on a shoulder strap. Three sets of rules meet on each of those trips. Federal disability rules say you take the rider. Federal hazardous materials rules say how the oxygen rides. State and broker rules say who may touch it.

## Can a NEMT company refuse a rider who uses oxygen?

Not because of the oxygen. The Department of Transportation's disability rules apply to public and private transportation companies alike. They bar you from stopping a rider with a disability from traveling with a respirator or portable oxygen supply, consistent with federal hazardous materials rules ([49 CFR 37.167(h)](https://www.ecfr.gov/current/title-49/section-37.167)). DOT's interpretation in Appendix D to part 37 explains the link: the hazardous materials rules permit a passenger to bring a portable medical oxygen supply on board, so a transportation provider cannot prohibit it.

That does not mean any vehicle can take any rider on oxygen. The oxygen still has to ride safely, and the rider's needs have to match the vehicle and crew you send. The [ADA requirements guide](https://nemtguide.com/guides/ada-requirements-for-nemt/) covers the rest of the disability rules.

## Who may handle the oxygen during the ride

On a NEMT trip, the rider runs the oxygen. The driver secures the tank and drives. States draw that line in slightly different places:

| Program | What the rule says | Source |
|---|---|---|
| Georgia Medicaid | Members supply and give their own oxygen. NEMT vehicles and drivers, stretcher vans included, are not equipped to supply, maintain, or administer it. | NEMT manual 801 and 811.6, version date July 1, 2026 |
| Virginia fee-for-service (MTM Health, broker for trips from October 1, 2026) | Drivers may not assist with oxygen unless the trip is on an ambulance. A rider on an ambulatory or wheelchair trip must be able to self-administer. | MTM Health member handbook, approved July 2026; the DMAS member manual (June 2026) says the same |
| New York Medicaid | A stretcher service may carry a rider who self-administers oxygen. Staff may never help with it or offer it, and the vehicle may not be equipped with its own oxygen or oxygen delivery supplies. Tanks must be secured. | Transportation policy manual, effective August 25, 2023 |
| New Jersey | A mobility assistance vehicle may carry a rider on their own portable supply without an EMT, if the crew never has to monitor, regulate, or control it. If the vehicle carries oxygen devices of its own, the crew member must hold EMT-Basic and CPR certification. | N.J.A.C. 8:40-5.2(c), 5.3(c), 5.5(a) |
| Ohio Medicaid | A non-emergency ambulance is necessary when the rider needs oxygen given or regulated by another person. | OAC 5160-15-23, effective July 1, 2021 |
| Medi-Cal (California) | A rider with a chronic condition who uses oxygen but needs no monitoring goes by wheelchair or litter van when clinically stable and able to self-monitor the oxygen system. A rider recently placed on oxygen, or one who needs monitoring, goes by ambulance. | Ground transportation manual, page updated August 2020 |
| Missouri (MO HealthNet) | Riders who need equipment only an ambulance carries, such as non-portable oxygen, get the non-emergency ambulance level. | NEMT manual, April 2026 |
| Illinois Medicaid | A medicar (wheelchair van) trip is for a rider whose condition does not require the administration of oxygen. A stretcher van may not carry a rider who needs supplemental oxygen that is not self-administered. | HFS handbook, March 11, 2024; 77 Ill. Adm. Code 515.845, amended November 1, 2024 |

Most of these programs draw the same line. A rider who can turn on, set, and watch their own oxygen rides in a car, wheelchair van, or stretcher van. A rider who needs someone else to give, adjust, or monitor it needs an ambulance, or in New Jersey a mobility assistance vehicle with an EMT on board. See [NEMT vs ambulance](https://nemtguide.com/guides/nemt-vs-ambulance/) for how the levels split.

Georgia applies the same logic to other equipment. A member who depends on a ventilator or other life-sustaining equipment must use portable, fully charged, battery-operated equipment and travel with an escort trained to manage it, and must tell the broker at booking. See [escorts and caregivers](https://nemtguide.com/guides/escorts-and-caregivers/).

## How much oxygen a NEMT vehicle may carry

Federal hazardous materials rules define a material of trade as a hazardous material carried on a motor vehicle to protect the health and safety of the driver or passengers ([49 CFR 171.8](https://www.ecfr.gov/current/title-49/section-171.8)). A rider's medical oxygen is carried for exactly that reason. The Hazardous Materials Table lists oxygen as a Division 2.2 nonflammable gas that also takes an oxidizer label, both compressed (UN1072) and as a refrigerated liquid (UN1073).

As of September 2026, the materials of trade section ([49 CFR 173.6](https://www.ecfr.gov/current/title-49/section-173.6), last amended August 4, 2026) sets these conditions:

| Rule | What it means on a NEMT trip | Section |
|---|---|---|
| Cylinder size | Each cylinder weighs 220 pounds (100 kg) or less, gas included | 173.6(a)(2) |
| Vehicle total | All materials of trade on board weigh 440 pounds (200 kg) or less together | 173.6(d) |
| Packaging | Leak tight, securely closed, secured against shifting, and protected against damage | 173.6(b)(1) |
| Cylinder standards | The cylinder meets federal cylinder rules. No outer box is needed. | 173.6(b)(5) |
| Labels | A DOT specification cylinder carries its required markings and labels | 173.6(c)(3) |
| Driver notice | The driver is told oxygen is on board and told the requirements of this section | 173.6(c)(5) |

Meet those conditions and no other hazardous materials rule applies, so the van needs no shipping papers or placards. The 440-pound total covers every material of trade on the vehicle, so a spare gas can or any other material of trade you carry counts toward the same limit.

A portable tank small enough for a wheelchair holder, a cart, or a shoulder bag is a small fraction of the 220-pound cylinder limit. What limits how many tanks you carry is room to secure each one, and your broker's rules.

The picture changes when a family member drives. The hazardous materials rules do not cover an individual carrying a hazardous material for non-commercial purposes in a private vehicle ([49 CFR 171.1(d)(6)](https://www.ecfr.gov/current/title-49/section-171.1)), such as a daughter driving her father to a doctor's visit in the family car. Your company carries riders for pay, so the materials of trade rules apply to you.

## How long a tank will last

A rider whose tank runs dry during a long will-call wait is an emergency you can see coming. Check the supply before you leave. Ask the rider or their oxygen supplier how many liters a full tank holds and at what pressure. With those two numbers, the gauge reading, and the flow rate, two formulas give a rough answer:

**Liters left = full capacity × gauge reading ÷ full pressure**

**Minutes left = liters left ÷ flow in liters per minute**

For example, say a full tank holds 400 liters at 2,000 psi and the gauge reads 1,000 psi. About 200 liters are left. That lasts about 100 minutes at 2 liters a minute, or a little over an hour at 3 liters a minute.

Plan for the whole day, not the drive: both legs, the appointment, and the wait for a [will-call](https://nemtguide.com/glossary/will-call-trip/) return. When the numbers are tight, ask the rider to bring a spare tank or a charged spare battery.

Two other kinds of equipment need their own questions. Liquid oxygen slowly runs out even when it is not in use, because it evaporates, according to MedlinePlus. A portable concentrator makes oxygen from room air but needs power, so the battery sets the limit.

## How to secure oxygen in the vehicle

The federal baseline is short: secured against shifting and protected against damage. State and broker rules show what that looks like in a van:

- **New Jersey** defines crashworthy as equipment, oxygen systems included, that stays firmly in place and poses no hazard to anyone in a crash or a sudden change of speed or direction. Its mobility assistance vehicle and ambulance rules bar rubber straps, shock cords, and hook-and-loop closures as restraints. The state's test is whether the item can be removed without unlatching or unbuckling its restraint (N.J.A.C. 8:40-1.3 and 4.4).
- **Illinois** requires a crash-stable, quick-release mounting bracket for each oxygen cylinder a stretcher van carries (77 Ill. Adm. Code 515.840(h)).
- **Virginia** requires self-administered oxygen on stretcher vans to be secured to the Ambulance Manufacturers Division's Standard 003, the oxygen tank retention system test (DMAS requirements updated May 26, 2026, and MTM Health's provider handbook, approved August 10, 2026). DMAS also requires every vehicle to be free of unsecured items.
- **New York** requires oxygen tanks in stretcher vehicles to be secured while in the vehicle.
- **Louisiana** broker MediTrans, in its operations manual for the Louisiana Healthcare Connections health plan (revised February 20, 2025), has providers carry a member's secured oxygen at no charge, as long as it can be carried and stowed safely.

In practice:

1. **Use a holder fixed to the vehicle** for any tank that is not on the rider's wheelchair, such as a bracket rated for cylinders.
2. **Check a wheelchair-mounted holder.** It should close around the tank, and the wheelchair itself must be fully tied down. See [wheelchair securement](https://nemtguide.com/guides/wheelchair-securement/).
3. **Secure the spare too.** A spare rolling on the floor is as dangerous as the tank in use.
4. **Protect the valve and regulator.** Keep them clear of doors, the lift, and securement straps.
5. **Route the tubing** so it cannot kink, catch on a seat belt buckle, or get shut in a door.
6. **Never put a tank in the trunk or cargo area** out of the rider's reach.

## Heat, flames, and smoking

Oxygen makes things burn much faster. MedlinePlus compares it to blowing on a fire. Its oxygen safety page (reviewed January 14, 2026) tells users to:

- keep oxygen about 6 feet from heat sources such as space heaters, candles, and fireplaces
- avoid petroleum-based creams and lotions on the face and upper body
- keep oil, grease, alcohol, and other liquids that burn away from the oxygen
- never store oxygen in a trunk, box, or small closet

Heat also raises the pressure inside a cylinder. Federal cylinder rules cap a filled cylinder's pressure at 131°F at 1.25 times its rated service pressure, with a few exceptions ([49 CFR 173.301a(d)](https://www.ecfr.gov/current/title-49/section-173.301a)). Keep tanks out of direct sun, keep the air conditioning working, and never leave a tank in a parked van. Virginia's fee-for-service rules (updated May 26, 2026) already require air conditioning that cools to 68°F and heat to 74°F, measured from the rear of the vehicle.

Smoking is the biggest risk. The U.S. Fire Administration warns never to smoke around medical oxygen. It can explode if a flame or spark is nearby, and it can still catch fire even when turned off. Program rules back that up:

| Program | Smoking rule |
|---|---|
| Georgia Medicaid (July 1, 2026) | No smoking on vehicles by passengers, attendants, or providers. No Smoking signs visible to all passengers. Drivers call the broker right away if a passenger will not comply. |
| Virginia DMAS (May 26, 2026) | Vehicles tobacco and smoke free, including smokeless tobacco, vapes, and e-cigarettes. A No Smoking sign inside every vehicle. |
| MTM Health agreement (Pennsylvania version, January 1, 2023) | Drivers may not let members or passengers smoke or use e-cigarettes in the vehicle. A No Smoking sign in all vehicles. |

Virginia also requires a working Class A, B, C fire extinguisher secured within the driver's reach. Keep one in every van, and train drivers to use it.

## What drivers check at pickup

1. **Read the trip.** The manifest or booking should show oxygen. Georgia and Verida ask members to report oxygen when they schedule, and Virginia's member manual lists oxygen among the special needs to report.
2. **Confirm the rider runs it.** If the rider or a trained escort cannot manage the oxygen, do not adjust it. Call dispatch or the broker before you load.
3. **Look at the tank.** The label should be on and readable, the cylinder free of dents and heat damage, and the valve and regulator intact. Listen for a hiss.
4. **Check the supply.** Read the gauge and compare it with the day ahead, including the wait.
5. **Secure every tank,** spares included, before the vehicle moves.
6. **Clear the cabin.** No smoking, no lighters in use, and no one applying oil-based products near the rider.
7. **Keep the tank with the rider** at drop-off. Do not keep it in the van between legs.
8. **Know the emergency plan.** If the rider has trouble breathing, stop safely and call 911. See [what to do in a medical emergency during a ride](https://nemtguide.com/guides/medical-emergency-during-a-ride/).

## Oxygen levels of service and billing

Some programs build oxygen into their levels of service. As of September 2026, Modivcare's New Jersey facilities page lists a wheelchair level with oxygen for riders whose oxygen must be provided and monitored by the transportation company, and a BLS ambulance level with oxygen for stretcher riders with the same need. Under New Jersey's rules, a mobility assistance vehicle that carries its own oxygen needs an EMT-Basic on board, and its equipment must meet the state's ambulance oxygen standards (N.J.A.C. 8:40-5.5).

Elsewhere, oxygen is not a separate charge on a van trip. South Dakota's secure medical transportation manual (updated August 2026), which covers wheelchair and stretcher riders, says oxygen and oxygen supplies are included in the base rate and are not paid separately. Illinois covers oxygen as a service when it is medically necessary and given by ambulance staff during transport. Check your state's fee schedule and your broker agreement before you promise anything beyond carrying the rider's own supply.

## Booking and training

Most problems with oxygen trips start at booking. Add these questions to your [trip intake](https://nemtguide.com/guides/nemt-trip-intake/):

- Does the rider use a cylinder, liquid oxygen, or a concentrator?
- What flow rate, and for how long can the supply run?
- Will the rider bring a spare tank or battery?
- Can the rider manage the oxygen alone, or will a trained escort ride along?
- Is the rider in a wheelchair with a tank holder, or will the tank need its own holder?

Then train every driver on the rules above. The materials of trade section itself requires that the driver be told oxygen is on board and told its requirements (49 CFR 173.6(c)(5)). Cover securing tanks, reading a gauge, the no-smoking rule, and what drivers may and may not do with the oxygen in your [NEMT driver training](https://nemtguide.com/guides/nemt-driver-training/). Put the same rules in your [policies and procedures](https://nemtguide.com/guides/nemt-policies-and-procedures/), and check your broker's provider manual for anything it adds.

## Frequently asked questions

### Can a NEMT driver help a rider with their oxygen?

Not with the oxygen itself. Georgia's NEMT manual (version date July 1, 2026) says NEMT vehicles and drivers are not equipped to supply, maintain, or administer oxygen, and members supply and run their own. MTM Health's Virginia member handbook (approved July 2026) bars drivers from assisting with oxygen unless the trip is on an ambulance. Securing the tank in the vehicle is part of the ride. Turning the flow up or down, changing tanks, or fitting the tubing is the rider's job, or a trained escort's.

### How many oxygen tanks can a NEMT van carry?

Federal rules set the outer limit. Medical oxygen carried to protect a passenger's health is a material of trade, which allows cylinders up to 220 pounds gross weight each and 440 pounds for all materials of trade on the vehicle together (49 CFR 173.6, as of September 2026). A portable tank that rides on a wheelchair or a cart weighs far less than that, so weight is rarely the limit. Room to secure every tank, spares included, and your broker's rules are.

### Do I need hazmat placards or shipping papers to carry a rider's oxygen?

No, as long as you stay within the material of trade rules. Under 49 CFR 173.6, a material of trade carried by motor vehicle in line with that section is not subject to the other hazardous materials requirements, so there are no shipping papers or placards. The section's own conditions still apply: the cylinder is marked and labeled, secured against shifting, protected from damage, and the driver is told that oxygen is on board and what the rules require.

### Can a rider bring a portable oxygen concentrator?

Yes. A concentrator makes oxygen from room air, so it carries no compressed gas, but it runs on power. MedlinePlus, the National Library of Medicine's patient site, notes that portable battery-operated concentrators exist and that home users need a backup tank in case the power fails. Georgia's manual requires members to use portable, fully charged, battery-operated equipment. Ask at booking how many hours the battery lasts and whether the rider carries a spare.

### Can a rider leave their oxygen tank in the van during the appointment?

Avoid it. MedlinePlus tells oxygen users not to store oxygen in a trunk, box, or small closet, and to keep it well away from heat. A parked van in the sun is no place for a tank. Georgia's manual also makes clear that drivers and attendants are not responsible for passengers' personal items. Send the tank in with the rider, and take it on the return leg the same way.

### What should a driver do if a rider on oxygen wants to smoke?

Say no, and do not move the vehicle while anyone is smoking. The U.S. Fire Administration warns that medical oxygen can explode if a flame or spark is nearby, and that the risk remains even when the oxygen is turned off. Georgia bars smoking on NEMT vehicles for passengers, attendants, and drivers, and requires drivers to call the broker right away if a passenger will not comply. Virginia and MTM Health require No Smoking signs, with vaping and e-cigarettes included.
