The South Coast Air Quality Management District has issued an Air Quality Alert due to elevated fine particulate matter levels due to wildfire smoke across portions of Los Angeles County. This Air Quality Alert is IN EFFECT UNTIL 5 PM PDT MONDAY. If you smell smoke or see ash due to a wildfire, remain indoors with windows and doors closed or seek alternative shelter, if feasible. Avoid vigorous physical activity and run your air conditioner and/or an air purifier. If possible, do not use whole house fans or swamp coolers that bring in outside air. Avoid burning wood in your fireplace or firepit and minimize sources of indoor air pollution such as candles, incense, pan-frying, and grilling. If you must be outdoors, keep the time brief and wear a tightly-fitted N-95 or P-100 respirator to help reduce exposure. Limit the use of gasoline powered lawn and garden equipment. Exposure to particle pollution can cause serious health problems, aggravate lung disease, cause asthma attacks and acute bronchitis, and increase risk of respiratory infections. People with heart or lung diseases should follow their doctor's advice for dealing with episodes of unhealthy air quality. Additionally, people with respiratory or heart disease, older adults, and children are particularly susceptible and should avoid prolonged exposure, strenuous activities or heavy exertion as conditions dictate. Levels of particle pollution can vary hour by hour and by location depending on fire behavior and local weather conditions. To view current and forecasted air quality levels, visit the South Coast Air Quality Management District Website at aqmd.gov or download the mobile app at www.aqmd.gov/mobileapp. Additional details for this air quality alert may be available at www.aqmd.gov/advisory.
