Three massive wildfires have erupted Tuesday across Los Angeles County amid dangerously high winds, prompting sweeping evacuations for residents.

Brent Pascua of the California Department of Forestry and Fire Protection told ABC News that the “extreme fire activity” and winds of the Palisades blaze are unlike anything he has ever seen.

For those escaping the fires, here are some safety tips from doctors:

Those in immediate danger are the residents within 25 miles of a fire, according to Dr. Zab Mosenifar, a lung specialist at Cedars-Sinai Medical Center.

Small particles in the air can travel hundreds of miles, and depending on the winds, particles can float for up to two weeks after a fire has been extinguished, Mosenifar warned.

Those especially in danger are children, the elderly and people with chronic respiratory problems, Mosenifar said.

“Breathing in smoke, spot and particulate matter in high concentration and/or for prolonged periods of time can result in short or long term lung damage,” said ABC News chief medical correspondent Dr. Jennifer Ashton.

“People who smoke, vape or have asthma are at higher risk for problems,” Ashton said.

“I recommend that anyone in the area wear an N95 particulate mask if possible,” she added.

Ashton urged residents with persistent coughing, shortness of breath, wheezing or chest tightness to seek medical attention and to wear goggles for eye protection.

“If your eyes are hurting or vision is impaired, seek medical attention immediately and do not rub your eyes as this could cause more damage,” she said.

Mosenifar recommended residents use an air filter in their home or set their air conditioner to recirculate the air.
