A working fireplace is genuinely safe when it's maintained and used correctly. Nearly every incident we hear about traces back to one of these habits being skipped.
- Burn only seasoned wood. Wood that's been split and dried for at least six months burns hotter and cleaner, producing far less creosote than green or wet wood. Damp wood is one of the biggest drivers of buildup in Minnesota winters.
- Get an annual sweep and inspection. A sweep and Level 1 inspection before the season starts catches buildup and damage before either becomes a bigger problem.
- Keep a 3-foot clearance. Furniture, decorations, and anything flammable should stay well clear of the fireplace opening, not just the hearth itself.
- Use a screen or glass doors. Sparks and embers popping out of an open fire are a real ignition risk to rugs, furniture, and curious pets.
- Never burn trash, cardboard, or wrapping paper. These burn unevenly hot and can send burning debris up the flue, occasionally out the top entirely.
- Let ashes cool completely before disposal, in a metal container. Ashes can hold enough heat to ignite a container or nearby combustibles for over 24 hours after a fire looks fully out.
- Install and test carbon monoxide detectors. Every level of the home with a fuel-burning appliance should have one, and the batteries should be checked twice a year.
- Keep the damper open until the fire is completely out. Closing it too early traps smoke and carbon monoxide inside the flue, where it can back up into the room.
If you ever have a chimney fire, even a small one, don't just resume using the fireplace afterward. See our guide on
what to do after a chimney fire before burning again.
