Industrial environments require ventilation to reduceexposure to excess heat and contaminants that are generated in the workplace;in some situations, cooling may also be required. Ventilation is primarily usedto control excess heat, odors, and hazardous particulate and chemicalcontaminants. These could affect workers’ health and safety or, in some cases,become combustible or flammable when allowed to accumulate above their minimumexplosive concentration (MEC) or lower flammable limit (LFL) (also called thelower explosive limit [LEL]) (Cashdollar 2000). Excess heat and contaminantscan best be controlled by using local exhaust systems whenever possible. Localexhaust systems capture heated air and contaminants at their source and mayrequire lower airflows than general (dilution) ventilation. This chapterdescribes principles of ventilation practice and includes other information onindustrial hygiene in the industrial environment. See Chapter 33 for moreinformation on the selection and design of industrial local exhaust systems.Ventilation Design PrinciplesGeneral Comfort and Dilution VentilationHeat ControlEnergy Conservation, Recovery, and SustainabilityNo. of Pages: 9
