By mid-1950, a Safety and Fire Protection Division, SFOO, had been organized with almost a complete change in personnel. Industrial safety, traffic, and fire protection engineers had been added, while total personnel had been cut to 12. Employment of two additional fire protection engineers in the Fall of 1950 increased total personnel to 14, : In July 1951, SFOO staffs at Kansas City and Sandia Field Offices included one safety engineer each plus a clerk-stenographer at Sandia. These three positions had been eliminated by the end of 1951. In the general reorganization of July 1951, the operation was divided into an SFOO headquarters staff and a Los Alamos Field Office staff. SFOO staff personnel were cut to eight. This was raised to nine with the addition of a sanitary engineer in April 1953, to provide staff assistance in radiological safety, industrial hygiene and sanitation, and contaminated waste disposal. A Health and Safety Branch was established in the Los Alamos Field Office to direct industrial safety, community and traffic safety, and the project fire department. It also was assigned responsibility for operation of the Police department, the Health and Sanitation Branch, and later the Industrial Wastes section. As of mid-1953, the administrative staff of Los Alamos Branchtotaled 7. SFO field installations coming under Safety and Fire Protection division cognizance more than doubled between 1950 and mid-1953. The workload was further increased by assignment of responsibilities at all domestic storage sites, and in 1952, of radiological safety and industrial health. The Division works closely with the field offices, and other SFOO and contractor installations in the fields of industrial, public and camp safety, health, and fire protection; reviews plans for all new construction and modifications for compliance with established codes and standards; advises and assists SFO offices and contractors in establishing cri- teria and developing and carrying out health, safety and fire protection programs; and makes periodic surveys of all facilities to assure that Commission standards of physical conditions and performance are being maintained. Safety and Health Direct safety supervision of contractor operations had been withdrawn by Fall 1951, with but one exception. In application of a new concept of construction safety program ad- ministration, the architect-engineers were assigned responsibility on all work under their direction. This worked well at Pantex, Rocky Flats, Eniwetok, and Nevada Proving Grounds where one architect-engineer supervised all construction and was justified in employing a qualified safety engineer. At Los Alamos, where the work was divided among several architect-engineers and the employment of a safety engineer by any one of them was not warranted, the LAFO Health and Safety Branch exercises part time safety supervision over construction activities while delegating much of the responsibility to the architect-engineers'’ construction inspectors. The emphasis placed on contractors! responsi- bility for safety and health together with the new controls have produced results thatare quite satisfactory. Attitudes have changed and occupational injury and disease rates had decreased by over 54 per cent during the three-yearperiod ending June 30, 1953. eg _ SFO occupational injury and disease records prior to calendar year 1949 were kept on a basis which does not permit comparison with subsequent years. Since 1949, the re- cords have conformed strictly to the American Standards Association Code. Accompanying charts present SFO occupational injury, disease, and Government vehicle accident rates.
