In Riverside, exposure often stacks up in predictable ways:
- Morning and evening commuting: Smoke can be thick around peak traffic hours, when you’re driving with windows up, recirculating air, or passing through neighborhoods where visibility drops.
- Indoor air in schools, gyms, and shopping centers: Many buildings rely on HVAC systems that may not be designed—or operated—for prolonged wildfire smoke events.
- Worksites with shifting schedules: Construction, logistics, landscaping, and other outdoor-heavy roles can force workers to stay on site even as air quality deteriorates.
- Suburban and residential “shelter-in-place” reality: Even when people try to stay indoors, smoke can enter through ventilation gaps. If air filtration isn’t adequate, symptoms may still worsen.
These scenarios matter legally because they help explain how exposure occurred and why a reasonable standard of care may have been missed.
