PM10 or coarse particles, also known as inhalable particles, are particles smaller than 10 micrometers but larger than 2.5 micrometers in diameter that are found in the air and can be generated by both mobile and stationary sources, naturally or anthropogenic, associated with generally to uncontrolled combustion and combustion processes in vehicles, foundries, paints, ceramics and power plants.
On pre-emergency and environmental emergency days, the use of masks is recommended for older adults, children, pregnant women, and chronically ill people.

Proper use of heaters
Always use dry firewood (less than 25% humidity), distributed by established merchants.
Always use chopped firewood, do not burn whole logs.
In wood-burning heaters, start the fire only with paper and dry kindling.
In wood heaters, keep the draft completely open for at least 10 minutes after starting the fire or refilling firewood.
Constantly check the smoke coming out of the flue of your heater or wood stove. If it is visible, open the vent on your heater to maintain a live flame. Never completely close the vent of your heater.
Prevent a layer of creosote and soot from forming on your barrel, as this increases the risk of inflammation, reduces heating capacity and causes more pollution to your stove.
If possible, replace the old heater with one with lower emissions and higher efficiency.
Privilege the use of alternative fuels such as: gas, electricity, briquettes, petroleum derivatives, pellets, among others.
All firewood dealers must have a municipal license, tax and forestry documentation, which proves the legal origin of the firewood.
Demand your receipt when purchasing firewood. With it you can assert your right as a consumer to exchange the product or get your money back if you are not satisfied with the purchase.
