Is Vaseline Flammable Around Oxygen? Safety & Usage Tips
Key Takeaways
-
Vaseline is flammable in the presence of oxygen. Petroleum jelly is derived from crude oil and acts as a fuel source. When combined with concentrated oxygen and a heat source, it can ignite quickly and burn intensely.
-
Oxygen doesn’t burn, but it accelerates fires. Oxygen-rich environments make materials ignite faster and burn hotter. Even a small spark, friction, or static electricity can trigger a fire when petroleum products are nearby.
-
Medical experts strongly advise against petroleum-based products. Healthcare professionals recommend using only water-based or oil-free moisturizers, gels, and creams during oxygen therapy to avoid fire hazards.
-
Safe alternatives exist. Products like KY Jelly, Aquegel, Cann-Ease, and pure aloe vera gel provide effective, water-based moisture without increasing fire risk.
-
Main Clinic Supply stands out as a trusted, expert provider of FDA-cleared portable oxygen concentrators (POCs), offering personalized guidance and same-day service to help oxygen users stay safe, comfortable, and fully informed about proper oxygen therapy practices.
Understanding a Common Oxygen Therapy Question
If you or a loved one uses oxygen therapy, you've likely heard warnings about Vaseline and petroleum jelly. Many patients reach for these familiar products to soothe dry, irritated skin around the nose and lips, common side effects of oxygen use. But is Vaseline really dangerous around oxygen, or is this just an overly cautious myth?
The answer is clear and important for your safety: yes, Vaseline and petroleum-based products do pose a real fire risk when used during oxygen therapy. While this might sound alarming, understanding why these products are dangerous and knowing safer alternatives will help you stay comfortable and protected while using your portable oxygen concentrator (POC).

The Short Answer: Yes, Vaseline Poses a Fire Risk Around Oxygen
Vaseline, also known as petroleum jelly, is made from petroleum, the same substance refined into gasoline and other fuels. When you combine a fuel source like petroleum jelly with concentrated oxygen from therapy and any source of heat or friction, you create the conditions needed for a fire.
Medical professionals across the healthcare field agree on this point. Pharmacists, respiratory therapists, and oxygen equipment providers all recommend avoiding petroleum-based products entirely during oxygen therapy. It's a sensible precaution based on the chemical properties of these substances and documented cases of burns occurring when these three elements came together.
Petroleum jelly, like Vaseline, creates fire risk during oxygen therapy because it's made from the same petroleum refined into fuels like gasoline.
Why Petroleum-Based Products Are Dangerous with Oxygen Therapy
To understand the risk, it helps to know what Vaseline actually is. Petroleum jelly is a semi-solid mixture of hydrocarbons derived from petroleum, the thick, dark liquid pumped from underground. While petroleum is refined in different ways to create various products, the base substance remains a hydrocarbon, which means it can burn.
During oxygen therapy, whether you're using a POC or a stationary system, you're breathing air with a higher concentration of oxygen than normal room air. Oxygen itself doesn't burn, but it acts as an accelerant, making fires start more easily and burn much more intensely.
When petroleum jelly is applied to your skin, particularly around your nose, lips, or hands, it creates a layer of flammable material in close proximity to your oxygen source. If any source of heat comes into contact with this combination, including friction from rubbing your face, static electricity, or any nearby flame, ignition can occur rapidly. The concentrated oxygen then causes the fire to burn faster and hotter than it would in normal air.
Healthcare organizations and medical professionals have documented cases where patients experienced burns when petroleum products ignited near their oxygen equipment. These aren't theoretical risks. They're real incidents that caused genuine harm and could have been prevented with proper product choices.
Understanding the Fire Triangle
Fire requires three elements working together, often called the fire triangle: oxygen, fuel, and heat. Remove any one of these three elements, and fire cannot start or sustain itself.
Oxygen
Oxygen acts as an accelerant. While oxygen itself doesn't burn, it speeds up combustion dramatically. The air we normally breathe contains about 21% oxygen. Oxygen therapy delivers much higher concentrations, sometimes 90% ± 3%, creating an oxygen-enriched environment where materials burn much faster.
Fuel
Fuel is any substance that can burn. Petroleum jelly, derived from crude oil, is essentially a refined fuel source. Other petroleum-based products like certain lip balms, lotions, and ointments also provide fuel for potential fires.
Heat
Heat can come from many sources such as friction from rubbing, static electricity from synthetic fabrics, smoking materials, candles, stoves, or even electrical sparks. During oxygen therapy, you want to eliminate fuel sources since oxygen is medically necessary and heat sources are part of daily life.
By choosing non-petroleum products, you remove the fuel element from the fire triangle, making your oxygen therapy much safer.
Medical Guidelines: What Healthcare Professionals Recommend
The medical community speaks with a unified voice on this topic. Respiratory organizations, oxygen equipment providers, and healthcare professionals across specialties all recommend the same approach: avoid petroleum-based products entirely during oxygen therapy.
Guidelines from respiratory health organizations emphasize using only water-based products on your hands, face, and inside your nose while receiving supplemental oxygen. These recommendations apply whether you're using oxygen continuously or just during certain activities.
Pharmacists have reviewed this question extensively and consistently advise that whenever skin moisturization is needed during oxygen therapy, patients should use water-based creams, oil-in-water emulsions, or products specifically designed for oxygen users. The consensus is clear because the chemistry is straightforward: petroleum products and concentrated oxygen create unnecessary risk.
Water-based nasal gels provide safe, effective relief from oxygen therapy dryness.

5 Essential Safety Tips for Oxygen Therapy Users
Following these practical guidelines will help you stay safe and comfortable during oxygen therapy:
-
Keep petroleum products away from your face and hands. This includes Vaseline, Vicks VapoRub, petroleum-based lip balms, and oil-based cosmetics. Store these products in a different room from where you use oxygen.
-
Read labels carefully before using any skin product. Many lotions, creams, and lip balms contain petroleum derivatives, even if it's not obvious from the product name. Look for "water-based" or "oil-free" labels, and check ingredient lists for petroleum, petrolatum, paraffin, or mineral oil.
-
Wash your hands thoroughly before handling oxygen equipment. If you've been cooking with oils or applying hand lotion, wash your hands with soap and water before touching your POC, nasal cannula, or tubing.
-
Use proper moisturizers regularly to prevent dryness. Don't wait until your nose is painfully dry. Apply water-based moisturizers consistently to maintain comfort and prevent the temptation to reach for petroleum products.
-
Maintain a five-foot safety zone around oxygen equipment. Keep all sources of flame, heat, or sparks at least five feet away from your oxygen concentrator and where you're receiving therapy. This includes candles, lighters, stoves, and space heaters.

Frequently Asked Questions (FAQs)
Can I use Vaseline anywhere on my body while on oxygen therapy?
It's safest to avoid petroleum-based products entirely during oxygen therapy, even in areas away from your face. Petroleum residue can transfer from your hands to oxygen equipment or clothing, creating potential fire hazards. If you must use petroleum products on distant body areas like your feet, thoroughly wash your hands before touching any oxygen equipment.
Are all lip balms unsafe with oxygen therapy?
No, but many popular lip balms do contain petroleum jelly or mineral oil. Read ingredient labels carefully and choose lip balms that are specifically water-based or beeswax-based without petroleum derivatives. Some brands make versions specifically safe for oxygen users.
How do I moisturize my nose during oxygen therapy?
Use water-based nasal gels like KY Jelly or Aquegel, which are specifically designed for this purpose. Apply a small amount inside your nostrils using a clean finger or cotton swab. These products provide long-lasting moisture relief without any fire risk and won't clog your nasal cannula.
