The Maricopa County Air Quality Department (MCAQD) has announced a "No Burn Day" for Thursday, December 12, due to elevated levels of Particulate Matter 10 (PM10), commonly known as dust, in Maricopa County, Arizona.

During a No Burn Day, several mandatory restrictions are imposed. These include a prohibition on wood burning in residential fireplaces, chimeneas, outdoor fire pits, and similar outdoor fires. This ban extends to hotels and restaurants and includes individuals or businesses with permits for open burning. Additionally, government employees and contractors are prohibited from using leaf blowers. Residents are also encouraged to refrain from using leaf blowers during pollution advisories. The use of off-road vehicles should be avoided as well.

Particle pollution poses health risks primarily to people with heart or lung diseases, older adults, and children. PM10 particles can penetrate deeply into the respiratory tract, causing short-term health effects such as irritation of the eyes, nose, throat, and lungs; coughing; sneezing; runny nose; and shortness of breath. These fine particles can also impair lung function and exacerbate medical conditions like asthma and heart disease.

MCAQD advises residents and employers to take steps to improve air quality by visiting Maricopa.gov/AQ for information on reducing air pollution. Recommendations include minimizing driving by carpooling or using public transit and avoiding activities that generate dust.

Particulate matter consists of tiny solid particles and liquid droplets in the air resulting from combustion or stirred-up dust. High levels occur when the air is stagnant or windy. PM10 refers to dust particles 10 microns or less in size.
