Following the outbreak of the Sandy Fire in Simi Valley, the Los Angeles County Department of Public Health issued an unhealthy air quality warning on Tuesday, May 19, 2026. Residents across Los Angeles and South Pasadena are urged to take precautions as smoke and ash drift into the region.
Health Risks and Recommendations
Wildfire smoke carries fine particles that can severely irritate the eyes, throat, and lungs. Health officials warn that even healthy adults can be negatively affected by the poor air quality.
“Smoke and ash can harm everyone, even those who are healthy,” stated Dr. Muntu Davis, Health Officer for Los Angeles County.
Vulnerable groups face even higher risks from the smoke. Children, pregnant women, the elderly, and those with compromised immune systems or heart conditions should be especially careful.
Staying Safe Indoors
Residents in South Pasadena and surrounding areas should stay indoors as much as possible while the advisory is active. Keep all windows and doors completely closed to preserve indoor air quality.
If you are running your air conditioning, ensure it is set to recirculate indoor air. Do not draw in outside air, as this can easily bring harmful particles into your home.
-
Avoid using fireplaces, candles, or vacuums.
-
Clean dusty surfaces with a damp cloth rather than dry dusting.
-
Wear an N95 or P100 mask if you absolutely must go outside.
Local Impact
While the 1,698-acre fire is burning in Ventura County, winds are actively pushing the smoke into our local communities. South Pasadena Unified School District (SPUSD) and other local schools are monitoring the situation closely.
Parents should expect modifications to outdoor activities, sports, or recess if the Air Quality Index (AQI) reaches unhealthy levels during the school day.
What to Do Next
Always check current conditions before heading outdoors. If you do not have air conditioning, consider visiting the South Pasadena Public Library at 1100 Oxley Street to stay safe and filter out the smoke during their regular hours.
