Protective Measures for Very Unhealthy Air Quality

When air quality is very unhealthy, the general public will be noticeably affected.

Sensitive groups, such as children, the elderly, pregnant people, and people with cardiac and pulmonary diseases, should remain indoors and limit all activities. Everyone should avoid outdoor exercise, wear a pollution mask outdoors and only go outdoors when necessary. Air purifiers should be turned on.
