Local exhaust systems consist of four elements; hoods, ducts, air cleaners, and air moving devices. The principles of local exhaust are described, and fundamental concepts in local exhaust ventilation are given. Enclosures, booth-type hoods, receiving hoods, and exterior hoods are described, and information is given on their applications. Regulations resulting from the Occupational Safety and Health Act of 1970 include several standards for local ventilation, both for the prevention of fire and explosion, and for controlling hazardous materials in the workroom to prevent illness or injury.
