California is one of the states that covers the welfare of its citizens in a eumprc.-.cns.vc fashion, a fact that is almost universal!)' recognized, and notabo so in respect to on-the-job safer)'. In fact, Federal officials rec ognize California's preeminence in this respect, and advise foreign safety officials to stud)' our safety setup. \Y ::r states to assume their _ it: cl piace in the hierarchy of government, Califor nia can meet or exceed Federal re quirements in matters of occupational health and safety. A signal instance of the recognition of tins fact is the recent agreement be tween Governor Edmund G. Brown and the .Atomic Energy Commission-- an agreement ratified by the State Legislature--under which California is assuming much of the licensing and regulatory functions that have been performed by the a k c . . Expected Changes Some of the changes anticipated by the end of th e 196 0 's arc --a trem endous increase in the num ber of workers under 25 and over 45; --far m ore w om en workers, w ith one out of every three workers being a woman; --a m uch faster increase in em ploym ent in construction, finance, insurance, and real estate; --m ore w h ite collar workers than blue collar workers, -th e ci.ntinc'r.g shift from an agricultural to a predom inated industrial econom y, with greater concentrations of the w ork force in the metropolitan districts; --the widespread increase in autom ation, and in record keeping; --the grow in g need for educational and medical services, and more apprenticeship training; --the increase in research and d ev elo p ment; --the continuing scientific and te ch n o lo g i cal advances, affecting industrial production in an aerospace age; and --the further shift from production indus tries to trades and services industries. Guiding Principles In fulfilling its legal responsibilities for the health and safety of workers, rhe d iv is io n has always upheld the principles of engineering, enforce ment, education, and r e a s o n a b le n e s s . These same principles will continue to guide the d iv is io n in future, for we are resolved to do all we can to meet the needs and demands of tire people of California in the way of industrial safety. Serious lenii poisoning o f tunnel workers in a San D iego cr proiecr was prevented recen tly l*;/ the vigilance and thoroughness of safety engineers of the d i v i s i o n or i .n d u 's TKI.vt. o.n;rv. C iosiiy watching the construction of a tw o ami .tie-half mile tunnel under the city, they iD.-arsed gasoline-im pregnated sand in one Ae.idir.g. saw that provisions for determ ining and controlling gasoline vapor concentration were instituted at once. , T h e gasoline, w h ich had seeped through . front an unknow n source above, was n o need at a depth of 75 feet and to an extent , o f about 140 feet. * T h e State Dcp.n nr.ent of Public H ealth >%: in l.o s A n g e le s round explosive hazards in air samples taken, and a certified chem ist ' " was then engaged by the contractor to make frequent tests of the tunnel atmosphere.

W ere it not for the thoroughness with ' w hich the div isio n* attacks a problem of this kind,- the* matter v.ouic have ended at this V ' 1 point. H ow ever, the no isio n insisted that tests y . e be made for tetraethyl lead, a com m on in gredient in com m ercial gasoline. . . S u r e e i H u u ' i i , tests by the Ethyl Corpora tion `skated that the. concentration of lead fistfscs lit the ttimid at tttOipht re was well V above safe inaits, even though the f.ra atd .gxplosion hazards J>ad been controlled. .

T h e d iv is i o n Chief and other members of the d i v i s io n s n ip then helped determine how the work could be resumed safely. W orkers were provided with air-supplied respirators for use in the contam inated area, to protect them from the peril of lead poisoning. j Safety .pays, and in many ways I --some quite unexpected--as this August 11th letter shows. _ - .May 1 thank yovt for your letter of July 22, in w hich you report the unsafe conditions you found at the mine? .
