Yes, PAM cooking spray is flammable. The product’s own safety data sheet classifies it as a flammable aerosol, and the can’s label warns users to keep it away from heat, open flames, sparks, and other ignition sources. The flash point listed on its safety data sheet is as low as -100°F, meaning the propellant gases can ignite at temperatures far below anything you’d encounter in a kitchen.
This catches many people off guard. PAM looks like a kitchen product and lives next to your stove, so it’s easy to forget you’re holding a pressurized can of flammable gas mixed with oil. Understanding why it’s flammable, and how fires actually start, can help you avoid a serious accident.
Why an Aerosol Cooking Spray Burns
PAM and similar cooking sprays use hydrocarbon propellants (typically propane, butane, or isobutane) to push oil out of the can in a fine mist. These are the same gases used in lighters and camping stoves. On their own, they ignite easily. When mixed with aerosolized oil droplets and sprayed into the air, they create a cloud that can flash into flame the instant it contacts a spark, burner, or hot surface.
The oil itself is less volatile. Canola oil, the primary ingredient in PAM Original, has a smoke point around 425 to 450°F and won’t spontaneously ignite until well above that. But in aerosol form, the propellant does the dangerous work. It vaporizes the moment it leaves the nozzle, creating an invisible, flammable gas cloud around the spray stream. The European Commission’s Scientific Committee on Food has specifically noted that oil-based aerosol cooking sprays “may carry some risk of flammability” because of this combination.
How Kitchen Fires Start With PAM
The most common scenario is straightforward: someone sprays PAM toward a pan that’s already on a lit burner. The mist passes through or near the flame, ignites, and a brief but intense fireball flares up. This can happen even if you aim away from the flame, because the propellant gas disperses wider than the visible spray pattern.
A less obvious risk involves the can itself. PAM cans have a vent on the bottom designed to release internal pressure safely. Lawsuits filed against ConAgra, the manufacturer, alleged that these vents were opening without warning, exposing the flammable liquid contents to nearby heat sources and causing the cans to ignite. If a can is stored too close to a stove, on a shelf above a toaster oven, or anywhere it absorbs significant heat, the pressure inside can build and the vent may discharge flammable material.
Residue buildup is another factor. A thin layer of cooking spray accumulates on oven walls, stovetops, and grill grates over time. This oily film can ignite at high temperatures, particularly during oven self-cleaning cycles or when grilling over direct flame.
What the Label Actually Says
PAM’s safety data sheet includes several standard hazard warnings for flammable aerosols. The key ones are direct:
- Keep away from heat, hot surfaces, sparks, open flames, and other ignition sources.
- Do not spray on an open flame or other ignition source.
- No smoking while using the product.
Under federal regulations, aerosol products containing flammable propellants must carry the hazard statement “Extremely flammable aerosol” on workplace labels unless they fall under consumer product labeling rules instead. Consumer cans of PAM follow labeling requirements set by the Consumer Product Safety Commission, which is why the exact wording on the can you buy at the grocery store may differ slightly from an industrial safety sheet. Either way, the message is the same: this product can catch fire.
Using PAM Safely
The simplest rule is to never spray PAM near any active heat source. That means turning off the burner before spraying, or spraying the pan away from the stove entirely and then placing it on the heat. Even a pilot light on a gas stove counts as an ignition source.
Storage matters just as much as application. Keep the can in a cool, dry cabinet, not on the counter next to the stove or on a rack above a heat-producing appliance. Temperatures inside a cabinet near an oven can climb high enough to increase pressure inside the can over time. If a can looks dented, swollen, or damaged, don’t use it.
For grilling, the same approach applies: spray the grill grates before lighting, not after. The combination of open flame and pressurized aerosol is exactly the scenario most likely to produce a dangerous flare. If you need to grease a hot surface, a paper towel dipped in oil and held with tongs is a safer alternative.
Alternatives That Aren’t Flammable
If the flammability risk makes you uneasy, non-aerosol options eliminate the propellant entirely. Pump-style oil misters let you fill a reusable bottle with whatever cooking oil you prefer and spray it manually. The mist isn’t as fine as an aerosol, but there’s no pressurized gas involved, so the fire risk drops to whatever the oil’s natural ignition point is, which for most cooking oils is well above normal cooking temperatures.
Simply pouring a small amount of oil into the pan or brushing it on with a silicone brush works just as well for most cooking tasks. You lose the convenience of a one-handed spray, but you gain the ability to safely apply oil to a hot surface without worrying about a flash fire.
