# Wildfire Smoke and Schools: What Parents Need to Know About Air Safety

Families across Los Angeles face an urgent question as schools reopen following devastating wildfires. Wildfire smoke contains toxic chemicals that pose real health risks, particularly to children whose lungs are still developing.

Wildfire smoke carries fine particulate matter and gases including carbon monoxide and volatile organic compounds. These particles penetrate deep into the respiratory system. Children face greater vulnerability because their lungs develop until age 18, and they breathe more air per pound of body weight than adults.

Schools like Pali High must assess air quality before welcoming students back. The EPA's Air Quality Index measures pollution levels. When the AQI exceeds 150, outdoor activities become unsafe for sensitive groups. Above 200, the agency recommends keeping people indoors entirely.

Health experts recommend schools monitor real-time air quality data from local monitors rather than relying on general forecasts. Dr. Kari Nadeau, an immunologist at Stanford University, emphasizes that smoke exposure can trigger asthma attacks and reduce lung function in healthy children. Children with existing respiratory conditions face compounded risks.

Parents should watch for warning signs: coughing, wheezing, shortness of breath, or chest pain during or after outdoor activities. These symptoms warrant a call to the pediatrician.

For students returning to campus, schools should ensure HVAC systems include high-efficiency filters that capture fine particles. Opening windows during smoky conditions worsens indoor air quality. Teachers can move PE and outdoor classes indoors until air quality improves substantially.

Individual masks matter too. N95 respirators provide protection when properly fitted, though they require children to maintain proper placement. Standard surgical masks offer minimal protection against wildfire smoke particles.

The timeline for safe return depends on local air quality recovery. Rather than arbitrary dates, schools should establish
