Title Practices for ventilation and operation of open-surface tanks.
Bibliographic information ANSI Z9.1-1977, American National Standard Institute, 1430 Broadway, New York, N.Y. 10018, USA. Standard approved 4 May 1977. 40p. Illus. 8 ref. Price: US-$6.50.
Abstract This standard concerns the protection of operators from contact with gases, vapours, mists or liquids used in or released by open-surface tank operations. It also covers the design of ventilating systems for controlling and removing such gases, vapours or mists but does not cover fire protection. Contents: construction specifications; classification of open-surface tank operations; local exhaust and general ventilation; control requirements (control velocity, enclosing-hood, lateral and canopy exhaust); spray cleaning and degreasing; control means other than ventilation; system design (capacity, static pressure, design, construction); operation (airflow, discharge and recirculation, etc.); personal protective equipment; special precautions for cyanide; installation, maintenance, and inspection of tanks; drainage, etc.; vapour degreasing tanks. Tables: chemical data, flash point, rate of mist evolution; toxic concentrations; classification of operations and airborne contaminants, etc. Diagrams: push-pull ventilation system; enclosing hoods, canopy hoods, rim exhaust, etc.
