It is the American Standard Safety Code tor Open-Surface Tanks, Z9.1-1951. Operations involving the immersion of materials in liquids and their subsequent removal are covered in this code. These include electroplating, washing, anodizing, pickling, quenching, dyeing, dipping, tanning, dressing, bleaching, degreasing, alkaline cleaning, stripping, rinsing, and digesting. The safety of the operator is the primary concern of this standard. T h e provisions are intended to protect h i m from contact with gases, vapors, mists, or liquids involved in any open-surface tank operation that might injure his health. Rules on personal protection are included as well as rules on operation, inspection, maintenance and installation, special precautions for cyanide, and vapor degreasing tanks. Provision is made to allow the use of both control means other than ventilation, and methods of ventilation involving supplied as well as exhausted air. The appendix includes tables of the resistance to corrosion of materials used for hoods, ducts, and exhaust fans, as well as seven pages of typical exhaust hood designs. This standard is a revision a n d expansion of the American Standard Safety in Electroplating, Z9.1-1941. Work on the American Standard Safety Code for Ventilation and Operation of Open-Surface Tanks, Z9.1-1951, w a s sponsored b y die American Industrial Hygiene Association, the American Society of Heating and Ventilating Engineers, and the National Association of Fan Manufacturers. Under the procedure of t h e American Standards Association, labor groups, government departments, insurance concerns, manufacturers, and users of this equipment were represented o n the committee that developed t h e standard. Copies of the code may b e obtained from the American Standards Association, 70 East 45th St., N e w York 1 7 , N. Y., at seventy-five cents a copy.
