An Air Quality Action Day will be in effect for Johnson County Monday.
Forecasters with the Indiana Department of Environmental Management are anticipating higher ozone levels as hot and hazy conditions make their way into the area this week. High temperatures near or over 90 degrees, combined with light winds, are expected to lead to conditions that are suitable for ozone to build to the Unhealthy for Sensitive Groups level, according to an IDEM news release.
Ground-level ozone is formed when sunlight and hot weather combine with vehicle exhaust, factory emissions and gasoline vapors. Ozone in the upper atmosphere blocks ultraviolet radiation, but ozone near the ground is a lung irritant that can cause coughing and breathing difficulties for sensitive populations, officials say.
Sensitive groups should reduce or avoid exertion and heavy work outdoors during these conditions, according to IDEM.
Officials say the public should consider taking the following actions to help improve air quality:
- Carpool or use public transportation;
- Avoid using the drive-thru and combine errands into one trip;
- Turn off engines instead of idling for long periods of time;
- Avoid using gas-powered equipment;
- Conserve energy by turning off lights and setting the air conditioner to a higher setting;
- Use propane gas instead of charcoal when grilling outdoors.
As a reminder, officials say Indiana’s open burning laws make it illegal to burn trash and generally prohibit open burning. Residents can visit IN.gov/idem/openburning/ for more information.
