Tuesday started with a scare at the LAPD's C. Erwin Piper Technical Center in downtown Los Angeles, where hazmat crews with the Los Angeles Fire Department converged after staff found an unknown substance inside the building. Firefighters in full protective gear moved in as the area was secured, specialist teams collected samples for testing, and two people were checked out at the scene but declined to be taken to a hospital.

Officials' response

According to a Los Angeles Fire Department alert, crews responded around 6:25 a.m. to the C. Erwin Piper Technical Center in the 500 block of Ramirez Street and located an unidentified substance. Two people were evaluated and refused hospital transport, and the Los Angeles Department of Transportation assisted with the cleanup. LAFD listed the incident as "Now Static" and directed further media questions to the LAPD.

What footage shows

Aerial video showed teams in full hazmat suits entering the building and setting up decontamination equipment outside, as reported by CBS Los Angeles. The outlet reported that crews worked to secure and clean the area while investigators tried to determine what the substance was.

Why Piper Tech matters

The C. Erwin Piper Technical Center, better known as Piper Tech, is a city-owned hub for municipal services, including distribution and printing operations. The building at 555 Ramirez Street is listed on the City of Los Angeles Distribution Center page. That mix of tenants helps explain the fast, multi-agency response whenever anything potentially hazardous turns up there.

Context

Unknown-substance calls have become a recurring issue around Los Angeles, prompting LAFD hazmat teams to roll out, decontaminate people when needed, and check for possible exposures. In December, LAFD crews declared another hazardous materials incident "Now Static" after decontaminating and transporting multiple people, according to earlier reporting by CBS Los Angeles. Samples from scenes like these typically have to be sent out for lab analysis before officials know exactly what they are dealing with.
