by Brianna Crandall — December 24, 2010—The American Industrial Hygiene Association (AIHA), in collaboration with the American National Standards Institute (ANSI), has released two new fundamental consensus standards that promote conformity among assessment systems.
ANSI/AIHA Z9.9-2010 Portable Ventilation Systems describes good practices related to the design, manufacture, labeling, use and application, and maintenance and testing of portable ventilation systems used for the control of airborne contaminants or environmental conditions. Intended users of this standard include owners of facilities, designers and manufacturers of portable ventilation equipment, employers, industrial hygienists and safety professionals, maintenance personnel, and end-users.
The revised ANSI/AIHA Z9.10-2010 Fundamentals Governing the Design and Operation of Dilution Ventilation Systems in Industrial Occupancies establishes minimum requirements for the commissioning, design, specification, construction, installation, management, operation, maintenance and testing of dilution ventilation systems (including demand dilution ventilation) used for the reduction, prevention and control of employee exposure to harmful airborne substances in the industrial environment. The standard establishes minimum requirements to provide safe and healthful working conditions in industrial employee occupancies.
