Is it safe to burn driftwood in a backyard fire pit near the coast?

Short answer

Why people ask this

People living near the coast often collect driftwood and wonder if it’s fine to burn in a backyard fire pit. The salty air, steady sea breezes, and nearby neighbors can make it seem convenient but tricky. Coastal driftwood is usually saturated with sea salt; when burned, the chlorides can form highly irritating hydrogen chloride gas and contribute to toxic compounds like dioxins. Wind patterns along the shoreline can carry sparks and salty smoke farther than expected, increasing fire and nuisance risks. Many coastal towns also restrict burning due to air quality, dune vegetation, and dense neighborhoods.

When it might be safe

There are no commonly accepted situations where this is considered safe.

When it is not safe

• Salt-soaked driftwood releases chlorine-containing fumes when burned, which are harsh on lungs and eyes.
• Coastal breezes can loft embers and salty smoke into neighboring yards, decks, and dune grasses.
• Marine debris and dock wood may be treated or contaminated, adding unknown toxins to the fire.
• Dense coastal housing and typical air inversions increase smoke impact on nearby homes.
• Many coastal municipalities and beach communities restrict backyard wood burning and driftwood fires.

Possible risks

• Irritant smoke (hydrogen chloride) and potential dioxin formation from burning salt-laden wood.
• Wind-driven embers igniting dry beach grass, fences, mulch, or stored gear.
• Corrosive, salt-laden soot accelerating rust on grills, railings, and patio hardware.
• Worsened air quality for close neighbors in coastal tracts and for sensitive groups (asthma, COPD).
• Fines or citations for violating local coastal burn bans, beach wood rules, or HOA restrictions.

Safer alternatives

• Use seasoned, untreated inland hardwood or certified kiln-dried firewood purchased locally (not driftwood).
• Choose a propane or natural-gas fire pit with a flame screen; it’s cleaner and less wind-sensitive.
• If allowed, burn manufactured low-ash firelogs without chlorine additives and use a spark screen.
• Check local coastal air district and city rules; consider designated beach fire rings with permits when available.
• Position any fire pit with wind in mind (onshore/offshore), keep a hose/extinguisher ready, and clear combustibles within 10 feet.

Bottom line

Coastal driftwood is salt-soaked and unpredictable; burning it in a backyard fire pit creates corrosive, irritating smoke and higher fire spread risk in windy shoreline neighborhoods. Stick to clean, untreated firewood or cleaner fuel options and follow local coastal rules.
