Performing. maintenance. work. on. an. electric. grid. is. a. daring. job. that.demands. a. high. degree. of. skill. and. attention.. It. is. therefore. handled.,.several.regulations. and. standards. have. been. developed. to. address. every. electric.,.1970,“”.Before.this.legislation.was.implemented,.about.15,000.job-related.fatalities.(,000.cases.of.illnesses.To.administer.the.act,’,,.and.improving. safety. and. health. in. the. workplace.. On.May. 29,. 1971,.,,.it.uses.the.service.of.engineers,.scientists,.standards.writers,.attorneys,.and.other.technical.and. support.personnel. OSHA’s.Code.of.Federal.Regulation.(CFR) with. several. job-related. issues. such. as. electric,. mechanical,. and. chemical.’s.standard.29.CFR.1910.,.1910-269,.and.1910-302.
The. Institute. of. Electrical. and. Electronic. Engineers. (IEEE). has. sev
eral. working. groups. and. standard. committees. devoted. to. electric. safety..
dards.worldwide..As.a.matter.of.fact,.OSHA.rules,.in.most.cases,,, are. often. based. on. having. workers. memorize. a. set. of. rules..Logical. explanation. of. these. rules. may. not. be. provided. to. field. workers.or. be. fully. understood. by. them.. When. a. rule. is. forgotten. or. incorrectly.extrapolated,,
learning. will. certainly. improve. the. safety. at. worksites.. However,. unfor
tunately,. most. power. engineers. are. not. familiar. with. the. electric. safety.
