Air quality advisory for Santa Clarita, Castaic areas

“It’s best to avoid using swamp coolers or whole house fans that bring in outside air,” the agency said. “Residents should also avoid burning wood in their fireplaces or firepits. And, if they absolutely must be outside, a properly fit N95 mask or P100 respirator may provide some protection.

The Post Fire started at about 1:45 p.m. Saturday at Ralph’s Ranch and Gorman School roads, near the Interstate 5y, Los Angeles County Fire Department spokesman Craig Little told City News Service.

Some 1,747 personnel wee involved in the firefighting effort.
