Severe Air Pollution: A Code Red alert indicates that the air quality has deteriorated significantly and poses a significant risk to public health.
Unhealthy Conditions: The air quality during a Code Red alert is deemed "unhealthy" or "very unhealthy," meaning it can cause adverse health effects, especially for vulnerable populations such as children, the elderly, and individuals with respiratory conditions.
High Levels of Pollutants: Code Red alerts are typically triggered by high concentrations of air pollutants such as particulate matter (PM2.5 and PM10), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO).
Health Impacts: Breathing polluted air during a Code Red alert can lead to respiratory problems, worsen existing respiratory conditions, trigger asthma attacks, and increase the risk of cardiovascular issues.
Restricted Outdoor Activities: During a Code Red alert, individuals are advised to limit their outdoor activities, especially vigorous exercises, to minimize exposure to the harmful pollutants in the air.
Public Health Warnings: Local authorities and health agencies issue public health warnings and advisories during a Code Red alert to inform the public about the severity of the air pollution and recommend precautionary measures.
Triggering Factors: Code Red alerts can be triggered by various factors, including high temperatures, stagnant air conditions, wildfires, industrial emissions, and vehicle emissions.
Monitoring Stations: Air quality is monitored using a network of monitoring stations that measure pollutant levels and provide real-time data to determine when a Code Red alert should be issued.
Response Actions: During a Code Red alert, authorities may take actions such as implementing temporary pollution reduction measures, advising vulnerable populations to stay indoors, and recommending the use of air purifiers or masks.
Importance of Awareness: It is crucial for individuals to stay informed about Code Red alerts and follow the guidance provided by health authorities to protect themselves and minimize exposure to harmful air pollutants.
