Smoke from the fire contains fine particulate matter and other harmful pollutants. Exposure to smoke is unhealthy, even for short periods of time. It is important that Bay Area residents protect their health by avoiding exposure. If possible, stay inside with windows and doors closed until smoke levels subside. Set car vent systems to re-circulate to prevent outside air from moving inside. The use of indoor air filtration can also help reduce smoke exposure.

Smoke can irritate the eyes and airways, causing coughing, a dry scratchy throat and irritated sinuses. Elevated particulate matter in the air can trigger wheezing in those who suffer from asthma, emphysema or COPD. Elderly persons, children and individuals with respiratory illnesses are particularly susceptible to elevated air pollution levels and should take extra precautions to avoid exposure.
