Programs that monitor air pollution levels and notify the public when smog levels make the air unhealthy for sensitive groups or for everyone. Smog warnings are graded according to levels that may be harmful to people who are sensitive (stage I alerts), that are unhealthy for all people (stage II alerts) or that are hazardous (stage III alerts). People who are likely to be affected are advised to remain indoors, if possible, and to avoid strenuous outdoor physical activity; refrain from smoking; and avoid contact with people who are suffering from respiratory infections, traffic congested areas, and aerosols, dust, fumes and other irritants during episodes.
