A small flare-up from dripping fat is normal and often desirable for searing. A grease fire that climbs past the grate and catches the underside of the lid or nearby siding is a different problem, and the standard instinct — throwing water on it — is exactly the wrong move on a grease fire.
Know the difference before it happens, not during
Flare-ups are quick flames from fat hitting hot coals or a burner, usually gone in seconds once you move the food or close the lid partially to cut oxygen. A grease fire is sustained, climbing, and often accompanied by thick black smoke rather than the lighter smoke of normal cooking. If flames are higher than the food and not dying down within 10-15 seconds, treat it as a real fire.
Water makes a grease fire worse, not better
Water dropped on burning grease vaporizes instantly and can throw burning droplets outward, spreading the fire rather than dousing it. The correct response is to close the lid and shut the vents on a charcoal or pellet grill, or turn off the gas supply at the tank on a propane grill — cutting oxygen and fuel supply, not adding water.
Keep the right extinguisher within arm’s reach, not in the garage
A standard household fire extinguisher rated for grease (Class B or K) belongs within a few steps of the grill, not thirty feet away in a shed. By the time you retrieve one from storage, a manageable flare-up can become a real problem.

A fire blanket handles what an extinguisher can’t
If the fire has spread beyond the grill itself — a grease-soaked apron, a nearby towel, a deck railing — a fire blanket smothers flames without the mess or corrosive residue an extinguisher leaves behind, and it works on clothing fires in a way a spray extinguisher shouldn’t be used for.

Prevention beats reaction every time
Trim excess fat before cooking, keep a drip pan under fatty cuts, and clean grease buildup out of the bottom tray regularly — old hardened grease is what turns an ordinary flare-up into a sustained fire. A grill that’s cleaned every few cooks rarely produces a fire worth calling a real emergency.
