Los Angeles County fire officials delayed live fire training drills in Castaic, officials said Tuesday, due to a three-alarm fire in Maywood.

Residents will likely see fire and smoke in the hills surrounding Castaic in the next two weeks, but fire officials are cautioning residents that it’s probably going to be part of their fire drill, which will start Wednesday.

A commercial warehouse fire in Maywood, which was complicated by magnesium burning inside the buildings — a substance that reacts violently to water — left fumes that could be smelled in the Santa Clarita Valley and diverted resources that would have been used in the training.

Live fire is being used to train at Wayside, where the Los Angeles County Fire Department is holding Wildland Fire Training from June 14-30, according to a statement from Stephanie English, spokeswoman for the LACoFD.

“The ‘Spring Drills’ are an annual training opportunity held at the Peter Pitchess Honor Rancho in Castaic,” according to the statement. “This training opportunity allows firefighters to practice their skills, reinforce emergency communications, improve risk-management decision-making and strengthen fire-attack skills.”

Approximately 100 firefighters will be training daily in the area, according to fire officials, and they will be aided by helicopters that will be training for water drops.

Fire officials are mindful of weather conditions, and the drills will not be conducted in dangerous conditions.

Fire officials also took the occasion to offer several seasonal reminders, with fire season around the corner. Anyone interested in more information can visit the county Fire Department’s website, and use this guide for creating a Personal Wildfire Action Plan.

Any questions regarding the drills should be directed to the Fire Department’s Community Relations Office at 661-250-2710.
