Sterno is a brand of canned heat used for cooking, and sometimes warming, food. The main ingredient in Sterno is ethanol, which is highly flammable. Although Sterno cans are equipped with a metal lid that doubles as a snuffer, the cans can still pose a fire hazard if not used properly. If you're using Sterno to cook or keep food warm, be sure to follow these safety tips:
- Always use Sterno on a non-flammable surface, such as a concrete floor or countertop.
- Keep the can away from open flames and any other heat source.
- Don't overfill the can - leave about an inch of space at the top to allow room for expansion if the can overheats.
- Use only long-handled utensils when handling hot food cooked with Sterno.
- Never attempt to extinguish a Sterno fire with water - this will only make the fire worse. If a fire does start, smother it with a damp towel or blanket until it's extinguished.
