Fire is hot because thermal energy (heat) is released when chemical bonds are broken and formed during a combustion reaction. Energy is required to start the reaction, breaking bonds in the fuel and between oxygen atoms, but much more energy is released when atoms bonds together into carbon dioxide and water.

As the energy level rises and fire begins, oxygen is used in the combustion which creates fire. To increase the amount and heat (energy) from a fire, you can increase the oxygen.

Fire is the result of applying enough heat to a fuel source, when you’ve got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.

Wind has a strong effect on fire behavior due to the fanning effect on the fire. Wind increases the supply of oxygen, which results in the fire burning more rapidly. It also removes the surface fuel moisture, which increases the drying of the fuel. Air pressure will push flames, sparks and firebrands into new fuel.

After a fire in your building, it could take several weeks for the smells to go away. During this time, it’s important to clean thoroughly and ventilate as much as possible to improve indoor air quality.

Keep indoor air as clean as possible if you are advised to stay indoors. Keep windows and doors closed. Run an air conditioner, but keep the fresh-air intake closed and the filter clean to prevent outdoor smoke from getting inside.

Wearing a special mask called a “particulate respirator” can also help protect your lungs from wildfire smoke. Choose a mask called a “ • particulate respirator” that has the word “NIOSH” and either “N95” or “P100” printed on it. These are sold at many hardware and home repair stores and pharmacies.

Wildfire smoke will continue to affect the entire region. While western fires will contribute to some smoke, local fires seen in this loop will contribute to surface smoke levels.

Smoke from California wildfires traveling more than 2,500 miles across country.

The agency said the smoke is coming from wildfires burning in the Desert Southwest region. The biggest fire currently burning in that region is the Telegraph Fire in Arizona.

Easterly winds have spread a fire burning in the northeast corner of the Warm Springs Reservation and blown some smoke into the Portland area.

Ozone and PM2. 5 pollution contribute equally to Portland air pollution, with 1.5 unhealthy pollution days attributed to ozone and 1.3 unhealthy pollution days attributed to PM2. 5 pollution. Improvements to Portland air quality must therefore strive to manage both PM2.

Prior to this year, Portland’s record high on the Air Quality Index was an “unhealthy” rating of 157. Now, it’s more than three times that—last Sunday, the city’s air measured a hazardous 477 on the AQI. Short-term effects include headaches, sore throat, scratchy eyes and difficulty breathing.

The Lane Regional Air Protection Agency, or LRAPA, says some smoke from fires in Warm Springs and Klamath Falls has made it to the Willamette Valley.

We are in contact with Cal Fire, Oregon Department of Forestry, US Forest Service and the Command Post and there continues to be no threat to the City of Ashland. …

Lightning sparked the Lionshead Fire, which began August 16, 2020, in Lionshead Canyon on the Confederated Tribes of Warm Springs Reservation approximately 14 miles west of the Warm Springs community.

Key Facts. “NO ONE should be outside,” the county’s official Twitter account wrote Monday, asking employers and employees not to work outside. Air quality is considered unhealthy when it reaches 151 on the Oregon Department of Environmental Quality’s index.
