The Louisiana Department of Environmental Quality (DEQ) has declared an air quality action day for Baton Rouge on Friday.
It is the first Ozone Action Day of 2015.
Officials said the Air Quality Index indicates ozone will be at orange level, which is unhealthy for sensitive groups. Active children and adults, the elderly and people with respiratory diseases are urged to limit their outdoor activities and how much they exert themselves.
According to DEQ, weather conditions will be favorable for ozone formation in East Baton Rouge, West Baton Rouge, Iberville, Livingston, Ascension and Pointe Coupee parishes.
Everyone is encouraged to drive less, gas up and work outside after 6 p.m., hold off on work that involve oil based pain or chemicals that can produce a flame, use an electric starter for grilling outside and conserve energy at home.
