Health advisory issued regarding Tustin Hangar fire

The OC Health Care Agency and the South Coast Air Quality Management District issued an alert that the smoke and ash from the recent fire at a hangar located at the former Marine Corps Air Station Tustin may pose a health risk to some Orange County (OC) residents in the immediate and adjacent vicinity. There is no risk to Costa Mesa at this time.

The City will notify residents immediately if air quality impacts arise in Costa Mesa.

• If you are concerned about air quality, please take the following precautions:
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.
