(1)     for each indoor workplace or indoor public place where smoking is prohibited pursuant to the Dee Johnson Clean Indoor Air Act, a “NO SMOKING” sign shall be posted where it is clear, conspicuous and easily legible at each public entrance. Posting of “NO SMOKING” signs is the responsibility of the owner, operator, manager or other person having control of the indoor workplace or indoor public place; and

(2)     for each indoor workplace or indoor public place where smoking is permitted pursuant to the Dee Johnson Clean Indoor Air Act, a “SMOKING PERMITTED” sign shall be posted where it is clear, conspicuous and easily legible at each public entrance, unless an owner, operator or manager chooses to prohibit smoking in all or part of an indoor workplace or indoor public place where smoking is otherwise permitted.

B. Nothing in the Dee Johnson Clean Indoor Air Act shall be construed so as to require the posting of signs at a residence, except during the hours of business operation while it is being used commercially to provide child care, adult care or health care or any combination of those activities.
