Moving. machine. parts. have. the. potential. for. causing. severe. workplace. injuries,.
such. as. crushed. ingers. or. hands,. amputations,. burns,. and. blindness,. just. to. name.
a.few..Safeguards.are.essential.for.protecting.workers.from.these.needless.and.pre-
ventable. injuries.. Machine. guarding. and. related. machinery. violations. continuously.
rank.among.the.top.ten.OSHA.citations.issued..In.fact,.“Machine.Guarding:.General.
Requirements”.(29.CFR.1910.212).and.“Mechanical.Power.Transmission”.(29.CFR.
1910.219).were.the.number.three.and.number.eight,.respectively,.OSHA.violations.for.
the.manufacturing.sector.from.October.2006.to.September.2007,.with.2,258.and.1,476.
federal. citations. issued,. respectively.. Mechanical. power. presses. have. also. become.
an.area.of.increasing.concern..In.April.1997,.OSHA.launched.a.National.Emphasis.
Program.on.Mechanical.Power.Presses.(CPL.2-1.24)..This.program.targets.industries.
that.have.high.amputation.rates.and.includes.both.education.and.enforcement.efforts.
Machine. guarding. must. be. provided. to. protect. employees. in. the. machine. area.
from.hazards.such.as.those.created.by.point-of-operation,.nip.points,.rotating.parts,.
lying. chips,. and. sparks. (see. Figure  25.19).. The. guard. itself. should. not. create. an.
accident. hazard.. The. point-of-operation. guarding. device. must. be. designed. to. pre-
vent.operators.from.having.any.part.of.their.body.in.the.danger.zone.during.operat-
ing.cycles..Special.supplemental.hand.tools.for.placing.and.removing.material.must.
be.designed.so.that.operators.can.perform.without.their.hands.being.in.the.danger.
zone.. Some. of. the. machines. that. usually. require. point-of-operation. guarding. are.
guillotine.cutters,.shears,.alligator.shears,.power.presses,.milling.machines,.power.
saws,.jointers,.portable.power.tools,.and.forming.rolls.and.calendars.
Machines. designed. for. a. ixed. location. must. be. securely. anchored. to. prevent.
walking.or.moving,.or.designed.in.such.a.manner.that.they.will.not.move.during.
normal. operation.. Suficient. clearance,. provided. around. and. between. machines,.
facilitates.safer.operations,.setup,.servicing,.material.handling,.and.waste.removal.
It.is.also.good.practice.to.have.a.training.program.to.instruct.employees.on.safe.
methods.of.machine.operation..Supervision.should.ensure.that.employees.are.follow-
ing.safe.machine.operating.procedures..A.regular.program.of.safety.inspection.of.
machinery.and.equipment.should.exist.that.will.ensure.all.machinery.and..equipment.
is.kept.clean.and.properly.maintained.
