That's an excellent and very important question! Disposing of barbecue ashes improperly is a common cause of outdoor fires, so it's great that you're looking for a safe solution. The direct answer is yes, there are specifically designed containers for this purpose, though they are often called "ash cans" or "metal ash buckets" rather than typical trash cans.
The most common and recommended option is a heavy-duty metal ash can. Look for cans made of galvanized steel or other durable metals, often with a tight-fitting metal lid. These are not your average plastic bins; they are built to contain heat and prevent embers from escaping. Many feature a double-bottom or air-gap design to prevent heat transfer to the ground or deck. You might also find all-in-one "ash vacuum" systems, but a sturdy metal can is the classic, reliable choice.
Here’s a crucial safety tip: Never transfer ashes directly from your grill or fire pit. Always let the coals and ashes cool completely for at least 48-72 hours. Some people even recommend adding water to the cooled ashes before scooping them into the metal ash can. Even then, it's wise to store the sealed ash can on a non-flammable surface like dirt, stone, or concrete, away from your home, shed, or any flammable materials.
In short, investing in a dedicated, fire-resistant metal ash can is a simple step that significantly boosts your outdoor fire safety. It gives you peace of mind, knowing you're protecting your property and surroundings after enjoying your barbecue.
