1--Occupational Safety Political problems On the political side remains the timeworn problem of industry-government relations The difficult- task of the serious safety profes sional is to objectively advise his management regarding legislation and what may be con sidered government interference in safety mat ters and still, at the same time, encourage good men in public service to work to improve safety standards If safety people simply fight government "on principle," they will lose their objecbvity and professional stature, and this will probably only heighten the pressure from other quarters for stiff and inflexible regulation Organizational problems On the national scale, a wide variety of organizations are attacking specific aspects of the safety problem The National Safety Council is, of course, the giant m the field-- a strong, constructive, and non-political, non commercial giant It has repeatedly sought and often achieved cooperative division of labor between itself and other organizations in the safety field One of the guiding principles of the Council has been that there was work enough and credit enough for all It remains to be seen whether the best or ganizational forms have been found for par ticipation by all businesses m safety work Safety professionals should be ready to con sider new ideas and new forms A look to the future The future is, as it always has been, most uncertain Problems large and small, predict able and unpredictable can be expected to crowd upon the safety professional Some of these problems will call for reapplication of established safety techniques Others will call for radical departures and the creation of new methods and new organiza tional forms To be able to discriminate between the two situations will, perhaps, be the safety profes sional's greatest test References American Engineering Council Safety and Production New York, Harper & Brothers Publishers, 1928 American Insurance Association, Accident Prevention Department, 85 John St, New York, N Y Handbook of Industrial Safety Standards 10th rev , 1962 Andrews, E W "The Pioneers of 1912" National Safety News, 66 24--25, 64--65 (July 1952) Beyer, David Stewart Industrial Accident Prevention, 3rd ed Boston and New York, Houghton Mifflin Co 1928 Blake, Roland P, editor Industrial Safety, 3rd ed Englewood Cliffs, N J, Prentice-Hall, Inc, 1963 Board of Certified Safety Professionals, 501 S 6th St, Champaign, 111 61820 Campbell, R W "The National Safety Movement " Proceedings of the Second Safety Congress of the National Councd for Industrial Safety, pp 188-192, 1913 DeBlois, Lewis A Industrial Safety Organization for Executive and Engineer New York City, McGraw-Hill Book Company, 1926 DeReamer, Russell Modem Safety Practices New York, John Wiley and Sons, Inc , 1958 Eastman, Crystal Work Accidents and the Law New York, Chanties Publication Com mittee, 1910 Heinnch, H W Industrial Accident Prevention, 4th ed New York, McGraw-Hill Book Company, 1959 Holbrook, Stewart H Let Them lave New York, The Macmillan Co, 1939 Mennmger, K A Man Against Himself New York, Harcourt, Brace and World, Inc, 1956 18

CONCEPT AND SIGNIFICANCE 27 the relationship between cancer and occupational activity has given rise to the idea that other factors of a more general nature, such as environmental conditions connected with the social status or with some general extraneous factors, are of more importance in determining the variations in the incidence of cancer found in different groups of people.
