LOS ANGELES — The public is being asked to avoid the Temescal Ridge Trail in the Santa Monica Mountains Tuesday evening through Thursday while the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives conducts controlled fire testing.

The testing will begin Tuesday evening between Skull Rock and Green Peak, according to Brian Humphrey of the Los Angeles Fire Department.

"While this scientific testing will periodically include open flame in a small area that may be visible at a distance, it does not involve the burning of vegetation," Humphrey said. "Los Angeles Fire Department personnel will be present before, during, and after all testing to ensure public safety and environmental protection."

There will be no provisions for media or public access due to the terrain and logistics, Humphrey said, adding that aircraft/drone pilots were instructed to follow any FAA-issued restrictions for the area.

"During this time period, there is no cause for public concern, or need to report the small testing flames that may be periodically visible near Tesmescal Ridge to 911," he said.
