Above these limits, countermeasures protect passive smokers necessary. order not exceed upper tolerable threshold limit ppm it necesary fresh air supply 33 m 3 per hour cigarette smoked. Special attention should be paid groups people increased sensitivity e.g., asthmatics, allergic individuals, chronic bronchitis sufferers, children.
