A July 4 celebration in northeast Salem ended at the hospital after an explosion, believed to be caused by illegal fireworks, tore through a home, injuring five people and damaging nearby houses and cars. Emergency crews arrived to find multiple people with significant injuries, though police said those wounds were not reported to be life threatening.
Salem police said officers responded at about 10:44 p.m. to a report of an explosion at a residence in the 4200 block of Prairie Star Court Northeast. Five people were taken to hospitals and four of them had significant injuries. Detectives with the department’s Felony Crimes Unit are leading the investigation, with Salem’s bomb squad, the city fire marshal and the crime lab assisting in the post-blast work. A preliminary investigation suggests the blast was likely caused by illegal mortars used outside manufacturing guidelines, and authorities said no charges had been filed as of July 5, as reported by KATU.
Why Mortars Can Be Deadly
Mortar-fired aerial shells and display-grade fireworks are supposed to be used only in licensed, supervised shows because of the explosive force involved. When those devices are modified or handled outside approved procedures they can detonate dangerously close to people and structures, causing blast and fragmentation injuries. According to the Oregon State Fire Marshal, display-grade devices, often classified as 1.3G, require permits and certified operators and are not intended for consumer use.
State Law And Penalties
Oregon law restricts the sale, possession and use of display or explosive fireworks except under permits and licensed displays, and local fire and police agencies are responsible for enforcing those rules. Violations of the fireworks statutes in ORS Chapter 480 may be charged as a Class B misdemeanor and can bring criminal fines and civil penalties. The statutory language and penalties are detailed in ORS Chapter 480.
Neighbors And Next Steps
Neighbors reported a loud blast that rattled homes and left residents on edge as city crews worked overnight to secure the scene. Police told reporters they are unlikely to release detailed medical information but said they plan to share the ages of those injured later. Investigators have asked anyone with video or information to contact authorities. As KATU reported, the probe remains active and officials are urging the public to be cautious around any suspicious fireworks.
The investigation is ongoing, and authorities said they will update the public when more details are available. For now, officials are repeating the familiar warning to leave aerial and display fireworks to licensed professionals and to report suspicious activity to the Salem Police Department.
