Protecting Yourself from Wildfire Smoke

Post Date:11/16/2018 2:36 PM

This weekend, wildfire smoke from the Camp Fire is expected to heavily impact Millbrae and San Mateo County, reaching unhealthy levels today and through the weekend. People with heart or lung disease, older adults, and children should reduce prolonged or heavy exertion, and stay indoors as much as possible.

Stay Indoors

The most effective way to reduce exposure and avoid the ill effects of smoke is to stay indoors with windows and doors closed. If you have a central ducted air conditioning system, run the air conditioner while keeping the fresh-air intake closed to prevent outdoor smoke from getting inside, and if possible, install a high efficiency filter.

Avoid Going Outside

People should avoid exercising outdoors during smoky conditions. Exposure and the resulting health effects depend on the amount of time spent outside, level of exertion, and the level of air pollution. Consider eliminating outdoor activities altogether this weekend, or until air quality levels reach healthy levels.
