17--Building Construction and Maintenance from steel tools are capable of igniting sub stances such as explosives, lint, carbon di sulfide, and ethyl ether Nonferrous tools need inspection before each use to be certain that they have not picked up steel particles, which could produce friction sparks Keeping up-to-date The maintenance department should not overlook the potentialities of new products, cleaners, lubucants, paints, wood pieservatives, insulation, floor repair materials, pro tective coatings, alloys, and other develop ments It should also keep up with new applications of existing products New prod ucts or applications usually lead to better methods and safer practices Increased mechanization requires careful assessment of new potential hazards, espe cially m high-speed equipment and piocesses Use of color throughout the plant, as specified in the previous chapter wnll contribute to acci dent prevention and help develop high stand ards of operation Sometimes mechanical means help to offset potential hazards Centralized lubrication, floor cleaning machines, centralized spray painting equipment, steam cleaners, and other devices will help make a maintenance pro gram safer For frequently performed main tenance jobs, permanent accessories, such as hoists, fixed ladders, and catwalks, should be provided Maintenance piocedures should be reexam ined periodically for safer ways to do the job A special suggestion system should be set up for maintenance men so that they will be able to present new ideas or corrective meas ures Engineering books and service manuals should be a part of the mauitenance program Woikeis should be familiar with them and use them when necessary References American Institute of Architects, 1735 New York Ave NW, Washington, D C 20006 Standard Form of Agreement Between Owner and Contractor American National Standards Institute, 1430 Broadway, New York, N Y 10018 ``Cranes, Derricks, Hoists, Hooks, and Jacks," B30 Senes Practice for the Inspection of Elevators, A17 2 Safety Code for Elevators, Dumbwaiters, Escalators, and Moving Walks, A17 1 Safety Code for Portable Wood Ladders, A14 1 Safety Color Code for Marking Physical Hazards, Z53 1 Safety in Welding and Cutting, Z49 1 Safety Requirements for Demolition, A10 6 Safety Requirements for Fixed Ladders, A14 3 Safety Requirements for Floor and Wall Openings, Railings, and Toeboards, A12 1 Safety Requirements for Job-Made Ladders, A14 4 Safety Requirements for Personnel Hoists, A10 4 Safety Requirements for Portable Metal Ladders, A14 2 Safety Requirements for Scaffolding, A10 8 Safety Requirements for Steel Erection, A10 13 Safety Requirements for Temporary and Portable Space Heating Devices and Equipment Used m the Construction Industry, A10 10 Scheme for the Identification of Piping Systems, A13 1 Specifications for Industrial Accident Prevention Signs, Z35 1 Armstrong, Ralph W "Masonry Walls Against Wind," Construction Section Safety News letter, September 1967 Associated Ceneral Contractors of America, Inc , 1957 E St NW, Washington, D C Manual of Accident Prevention in Construction Huntington, Whitney Clark Building Construction Materials and Types of Construction, 3rd ed New York, N Y, John Wiley & Sons, Inc 1963 440
