OJAI, Calif. — An explosive hazard response at a residential neighborhood in Ojai has prompted a stern public safety advisory from regional bomb technicians after a well-meaning beachgoer transported a hazardous military explosive device to their residence, law enforcement officials reported.

The joint ordnance disposal operation was conducted by the Ventura County Sheriff’s Office Bomb Squad alongside specialized U.S. Navy Explosive Ordnance Disposal (EOD) technicians deployed from nearby Naval Base Ventura County Point Mugu.
The emergency response was initiated after a local resident contacted law enforcement dispatchers to report finding military ordnance along the coastline and moving it to their private property in Ojai.
Beach Discovery, Residential Transport, and Bomb Squad Response
According to an official incident advisory issued by the Ventura County Sheriff’s Office Bomb Squad, the incident began when a citizen walking along the shoreline spotted a metallic cylinder at the waterline.
Fearing for the safety of fellow beachgoers, the citizen picked up the device, transported it in their personal vehicle to their home in Ojai, and subsequently called 911 to request law enforcement pickup.
Upon receiving the report and description of the object, Ventura County Sheriff's deputies immediately secured a safety perimeter around the Ojai residence.
Bomb technicians assigned to the Sheriff's Bomb Squad arrived on scene alongside U.S. Navy EOD specialists from Point Mugu.
EOD technicians identified the object as a Navy MK25 Marine Location Marker—a pyrotechnic device containing red phosphorus used by military aircraft and surface vessels for search-and-rescue operations, anti-submarine warfare tracking, and target marking at sea.
EOD operators safely rendered the device inert and removed it from the residential neighborhood for controlled disposal.
Extreme Hazards of Phosphorus Marine Markers
Public safety officials warned that while the beachgoer acted with good intentions, moving the marine marker created a severe, life-threatening situation for both the vehicle occupants and the surrounding residential neighborhood.
Law enforcement agencies outlined the severe physical dangers associated with washed-up or expended military marine markers:
- Spontaneous Combustion: Marine markers contain white or red phosphorus. Even if an item appears spent or has been submerged in seawater, residual phosphorus dries out rapidly once removed from the water, leading to sudden, spontaneous reignition or explosion upon exposure to oxygen or movement.
- Extreme Thermal Energy: Phosphorus pyrotechnics burn at extreme temperatures reaching up to 3,000°F (1,650°C), making them capable of instantly melting metal, causing catastrophic structural fires, and inflicting lethal, deep-tissue thermal burns.
- Severe Chemical Toxicity: The smoke, gas, and chemical residue produced by ignited marine markers are highly toxic to human respiratory systems and skin upon contact.
"While walking on the beach, a concerned citizen noticed the marker at the waterline and out of fear for the safety of other beachgoers, decided to take the marker home and call law enforcement," the Ventura County Sheriff's Office Bomb Squad detailed in an official public warning.
"Although well intentioned, marine markers, even if wet and expended, are extremely dangerous. Residual phosphorus can dry out once removed from the water, then spontaneously reignite or explode when moved... If you come across an item that looks like a 'bomb' or other piece of military equipment please leave the item in place, evacuate the area, and call 911," bomb technicians emphasized.
Standard Protocol for Found Military Ordnance ("The 3 Rs")
Coastal areas surrounding Ventura County—including beaches near Point Mugu, Port Hueneme, and the Channel Islands—occasionally wash up military marine markers, signal flares, or historical ordnance due to oceanic currents and naval testing exercises.
Emergency management and EOD teams instruct community members to remember the "3 Rs" if they discover suspected military ordnance:
- Recognize: Identify that the object may be an explosive hazard (metal cylinders, canister shapes, fins, or military markings).
- Retreat: Do not touch, kick, shake, or move the item. Do not submerge it in dry containers or place it inside vehicles. Move at least 300 feet away from the object.
- Report: Immediately call 911. Provide dispatchers with the precise location, beach landmarks, or GPS coordinates so trained EOD personnel can respond and detonate or neutralize the device safely on site.
Residents with questions regarding bomb squad outreach, explosives safety, or non-emergency public safety inquiries can contact the Ventura County Sheriff's Office at (805) 654-9511. Official safety advisories are published on the Ventura County Sheriff's Office Bomb Squad Facebook Page.
