A Code Red air quality alert is a crucial notification system used to inform the public about severe air pollution levels. It is typically issued by environmental agencies, such as the Environmental Protection Agency (EPA) or local health departments, when air quality reaches hazardous levels.
When a Code Red air quality alert is in effect, it signifies that the air pollution has reached a level that can be detrimental to human health, particularly for sensitive groups such as children, the elderly, and individuals with respiratory conditions. The alert serves as a call to action for people to take necessary precautions and minimize their exposure to polluted air.
The specific criteria for a Code Red air quality alert may vary depending on the region or country. However, generally, it indicates that the air quality index (AQI) has surpassed a certain threshold, often indicating high levels of pollutants such as particulate matter (PM2.5 or PM10) and/or ground-level ozone (O3).
During a Code Red alert, individuals are advised to stay indoors as much as possible, especially during peak pollution hours. If venturing outside is necessary, it is recommended to limit physical exertion and avoid rigorous outdoor activities. People with respiratory issues may be advised to wear masks or utilize air purifiers to reduce their exposure to pollutants.
What’s causing the problem?
The air quality issues are the result of smoke from wildfires in Canada.
Crews there are keeping an eye on 400 active fires – more than 150 in Quebec alone.
NASA reports some of those fires were started by lightning strikes.
At least 26,000 people have been forced out of their homes so far.
Multiple states impacted
The smoke filled the sky outside Boston, and the view was hazy in Connecticut.
New York City public schools canceled all outdoor activities. At one point, New York reportedly had the world’s worst air pollution of any major city.
New Jersey’s governor warned people to limit time outdoors.
Pennsylvania Gov. Josh Shapiro had the same warning. He tweeted, “My team and I have been monitoring this situation over the past 24 hours. Smoke is affecting the entire Commonwealth.”
Why is the haze so concerning?
According to the Pennsylvania Department of Environmental Protection, the haze is made up of tiny particles.
Those particles can get in your lungs and make it difficult to breathe, and they’re especially dangerous for people with asthma or other lung issues.
Tips to stay healthy
The Pennsylvania Department of Health provided some tips to help people stay healthy.
All Pennsylvanians are encouraged to:
- Avoid strenuous outdoor activities.
- Keep outdoor activities short.
- Consider moving physical activities indoors or rescheduling them.
Tips to help keep particle pollution lower indoors:
- Don’t use candles or smoke indoors.
- Keep windows and doors closed.
- If you have an air filter in your home, now is a good time to use it.
- Clean or replace filters according to manufacturer recommendations.
- If you don’t have one and want to make your own portable air cleaner designed to reduce particles indoors, the EPA offers DIY information.
Air quality can affect your health, especially people who may be at greater risk, including:
- People with heart disease.
- People with lung disease, including asthma and Chronic Obstructive Pulmonary Disease (COPD).
- Older adults.
- Children and teenagers because their lungs are still developing, and they breathe more air relative to their size.
- People who are pregnant.
- People who work outdoors.
If you experience symptoms like trouble breathing or dizziness, seek medical attention. If you know a family member or neighbor who has one of the above conditions, remember to check in on them.

Q1: What triggers a Code Red air quality alert?
A1: A Code Red air quality alert is triggered when the air pollution levels reach a hazardous threshold, often determined by the environmental agencies or health departments based on criteria such as high levels of particulate matter or ground-level ozone.
Q2: How is a Code Red air quality alert communicated to the public?
A2: Code Red air quality alerts are typically communicated to the public through various channels such as news media, government websites, social media platforms, and emergency alert systems. Local authorities may also use phone notifications, text messages, or email alerts to reach residents.
Q3: Who should be most concerned about a Code Red air quality alert?
A3: While a Code Red alert is a matter of concern for everyone, certain groups are more vulnerable to the effects of poor air quality. This includes children, the elderly, individuals with respiratory conditions like asthma or COPD, and those with compromised immune systems.
Q4: What precautions should I take during a Code Red air quality alert?
A4: During a Code Red air quality alert, it is advisable to limit outdoor activities, especially during peak pollution hours. Stay indoors as much as possible, use air purifiers if available, and avoid physical exertion. If you must go outside, consider wearing masks designed to filter pollutants.
Q5: What measures are taken to address a Code Red air quality alert?
A5: In response to a Code Red alert, authorities may implement temporary measures to reduce pollution sources. These can include stricter emissions controls for industries, restrictions on burning wood or certain fuels, promoting public transportation or carpooling, and encouraging energy conservation practices.
Please note that the specific details and actions taken during a Code Red air quality alert may vary based on the region and the guidelines set by local environmental agencies or health departments.
