A31 -- Ventilation of the Industrial Environment (I-P)

Industrial environments require ventilation to reduce expo- sure to excess heat and contaminants that are generated in the workplace; in some situations, cooling may also be required. Ventilation is primarily used to control excess heat, odors, and hazardous particulate and chemical contaminants. These could affect workers health and safety or, in some cases, become combustible or flammable when allowed to accumulate above their minimum explosible concentration (MEC) or lower flammable limit (LFL) [also called the lower explosive limit (LEL)] (Cashdollar 2009). Excess heat and contaminants can best be controlled by using local exhaust systems whenever possible. Local exhaust systems capture heated air and contaminants at their source and may require lower airflows than general (dilution) ventilation. See Chapter 32 for more information on the selection and design of industrial local exhaust systems.
