In a place where smoking is partially allowed in Utah, the building owner, agent, or operator must conspicuously post a sign using the words, "No smoking is permitted except in designated areas" on all entrances or in a position clearly visible on entry into the place. Utah No Smoking Sign helps you comply with Utah Code Ann. § 26-38-1. "No Smoking" is printed in 1.6 inches height and international "No Smoking" symbol is 5 inches in diameter.
