Today is the last day consumer fireworks can legally be sold in Oregon, and Lake Oswego residents still lighting sparklers and fountains from the holiday weekend should know the rules before striking another match.

Consumer fireworks remain legal within Lake Oswego city limits under state law. That means fountains, ground spinners, smoke devices, pop-its, wheels, and flitter sparklers are permitted.

Some district-owned properties within the city may have additional restrictions; residents should check posted signage or contact the city.

Anything that flies into the air, explodes, or travels more than 12 feet horizontally on the ground is illegal statewide without a permit from the Oregon State Fire Marshal.

The banned list includes bottle rockets, Roman candles, firecrackers, M-80s, cherry bombs, aerial shells, and sky lanterns.

Residents in Stafford and other unincorporated Clackamas County areas face a stricter rule: all fireworks are banned through July 10, according to the Oregon State Fire Marshal's Office, citing increased wildfire risk.

Using illegal fireworks carries a Class B misdemeanor charge, fines up to $2,500 per violation, and an additional civil penalty of up to $500.

On federal lands, fines can reach $5,000 with up to six months in jail. The Oregon State Fire Marshal's Office said people who misuse fireworks could also be billed for firefighting costs, and parents may be held responsible for damage caused by their children.

Mark Johnston, assistant chief deputy with the Oregon State Fire Marshal's Office, said residents should confirm what's allowed in their specific location before lighting anything.

On July 4, five people were hospitalized with serious injuries in Salem after illegal mortars exploded on a residential street, sending debris up to 80 yards and damaging six vehicles and a home. Salem Fire Department Battalion Chief Nick Grice said alcohol was involved.

"The illegal ones, while they look cool, are dangerous and people do get injured," Grice said.

Oregon's most infamous fireworks case remains the 2017 Eagle Creek fire, when a teenager threw fireworks into the Columbia River Gorge canyon, burning roughly 48,000 acres. He is paying nearly $37 million in restitution.

Gov. Tina Kotek declared a statewide wildfire emergency in June, and more than 18 of Oregon's 36 counties are under drought emergencies. The state did not impose additional fireworks restrictions beyond existing law.

The City of Lake Oswego posted safety guidance on its official Instagram account advising residents to have water on hand, light fireworks one at a time, never relight duds, keep fireworks away from dry grass, and soak used fireworks in water before throwing them away.

Residents can report illegal fireworks use by calling their local non-emergency dispatch line. The Oregon State Fire Marshal's Office can be reached at [email protected].
