Additional Narrative Page 4 of 11 Incident Location:3825 HIGUERA South Incident Date:01/12/2026 Incident City, State, Postal Code:San Luis Obispo, CA 93401 Incident Number:26-00250  Incident Date:01/12/2026 Additional Narratives Authored By Authored Date E4 arrived on scene and met face to face with Higuera IC (BC3) and was given assignment of fire attack. A key card was handed to E4 Captain to access locked doors in the structure. E4 Captain had E4 FF pull a 2 1/2" to the glass door entrance for a wye line operation. E4 operator worked on getting a supply line at the closest hydrant on Higuera with the aid of E3 Engineer and CalFire BC. E4 Captain requested E3 to assist with grabbing both wye lines while E4 entered the main entrance to find access to the fire. The main open area on the west side of the building where all the cubicles were located was all clear with slight haze. As E4 Captain turned the corner, he noticed water on the ground from what appeared to be an active sprinkler on the other side of the wall and backtracked to a locked door. The key card was used to open the door and E4 was met with dark grey smoke banked all the way to the floor. There was zero visibility and TIC was used to assist in finding the seat of the fire. E4 and E3 made access in the room to locate the fire. Locating the fire was challenging due to zero visibility and glass walls making it challenging for the TIC to identify the fires location. As the two crews progressed further into room, the temperature was increasing indicating we were close to the seat of the fire. E4 eventually found the seat as the glass panes broke and the TIC was able to identify its location. E4 was able to knockdown the fire and E3 extinguished the fire as E4 had to back out due to low air warning. E4 personnel was deconed several times after initial entry and subsequent entries for salvage and lithium iron battery cleanup. T1 arrived at scene and was given the assignment for vertical ventilation by BC3. T1 set up aerial for roof access on the alpha side. T1 also threw a 35' ground ladder on side alpha. T1 was staffed with six personnel, two from medic rescue. Four of the six personnel access the roof via the aerial and the remaining two crew MR1 members stayed on the ground for support, adding and assisting with ground ladder locations and rehab. T1 made access to roof, roof was a saw tooth design construction. T1 ladder was placed at the exterior wall and the high point of the saw tooth design. T1 crew utilized a 14' roof ladder to assist in descending to a safe location at the bottom of the 8/12 pitched roof (roof was approx. 26'-30' long from top to bottom). T1 was notified of BC 3405 would be Roof Division. Roof construction was 29-gauge metal, rib style roof with 1/2"-5/8" plywood sheeting with approx. 20" TJI roof rafters with a 2' on center span. Top half of metal roof was covered in a thin layer of moss making it very slippery. T1 Captain and crew made our way near the South end (towards marketplace) of the roof. T1 requested a 24' ground ladder to be utilized as a roof ladder, from bottom of saw tooth to top. T1 cut an inspection hole to see construction material. T1 fully extended 24' ladder. T1 crew cut multiple 4x4 holes and extended the holes vertical as we made our way down the ladder. T1 face to face with T2 Captain requesting another 24' ladder for egress on side Alpha. T1's crew bottles ran low, exited the roof for bottle exchange. T1 returned to roof and extended vertical holes laterally. BC 3405 Roof Division was reassigned and T1 assumed Roof Division. T1 completed assignment and reported to med unit for EMS vitals evaluation. T-2 arrived and was assigned 2 out. T-2 was setting up at the entry point and was reassigned to RIC. FF-2 and PUMP-2 cached out the RIC complement near the entry point. T-2 coordinated cutting access for an additional ladder to the Alpha side, gaining access points around the building and tracking resources. T-2 also assisted with rehab setup. T-2 was released for city coverage.

SOURCE OF ACTIVITY On January 12, 2026, at approximately 0824, San Luis Obispo County Dispatch received a 911 emergency call reporting smoke and flames seen at 3825 South Higuera, San Luis Obispo, CA. 93401 in San Luis Obispo County. At approximately 0825 hours, while working my regular schedule as the SLO Fire Department (SLOFD) Fire Marshal (PREV20), I responded code 3 from my office at SLOFD Station 1, 2160 Santa Barbara Ave., San Luis Obispo, CA. I arrived at the fire scene at approximately 0838 hours and cleared it at approximately 1730 hours. OBSERVATIONS/ACTIONS Upon my arrival, I observed Battalion 3 (BC3), Truck 1 (T1), Engine 4 (E4), and Engine 3 (E3) entering the 10,000-square-foot commercial structure to begin a fire attack and ladder the roof for ventilation. I observed faint smoke coming from the southeast (A-D corner) of the building. I reported to the Higuera IC and was originally assigned to Safety; my role later changed to Medical Group Supervisor. I conducted a 360-degree building inspection and spoke with representatives from the ESAero business to confirm that no one had medical needs. No medial needs were requested. I then walked to nearby businesses and asked them to remain inside and turn off the HVAC due to smoke drifting southeast from the building. I contacted an SLO PD officer and asked whether we could expand the safety zone to keep people out of harm's way from the smoke. SLO PD officers assisted in expanding the perimeter. I then contacted the standby ambulance and confirmed they were on the Tac 1 radio channel. I assisted in setting up a rehab location with all necessary supplies. After suppression efforts were effective, I was then assigned to the Fire Investigations lead. My investigation report is available in the Image Trend Fire Investigation reporting system for further details. INVESTIGATION My investigation actions and findings are based on a scientific examination of the fire's origin and cause. Methodology The methodology I utilized during this investigation consisted of identifying all available data for origin determination, including witness accounts, an initial scene assessment, development of a preliminary fire spread hypothesis, an in-depth examination of the fire scene, reconstruction of the fire scene, development of a final fire spread hypothesis, and identification of the fire’s origin. I identified all available data for cause determination, including ignition sources, fuel packages, oxidizers, and circumstances. I used all available resources to develop fire-cause hypotheses and determine which best fit the credible data to identify the cause of this fire. During my investigation, I obtained witness statements. I conducted the interviews in full uniform. The following is a summary of the statements I collected. Systematic Approach I began my investigation by systematically walking through the fire scene, from exterior to interior, and gathering all available data to determine where and how the fire started.
