When.analyzing.accidents.for.human.barriers,.investigators.must.realize.that.the.ive.
barriers.discussed.often.operate.together..It.is.an.advantage.to.present.them.indepen-
dently.for.understanding..However,.it.is.also.important.to.make.ive.judgments.as.to.
which.barrier.may.be.the.primary.contributor.to.an.accident..Each.type.of.barrier.not.
only.requires.a.different.type.of.solution,.but.the.implementation.costs.of.the.solu-
tions.are.quite.different..The.barriers.to.human.performance.are
.
1.. Information. (Direction. and. Guidance)—Was. the. person. given. direction.
and.guidance.in.regard.to.performing.the.job?
.
2.. Tools.and.Equipment.(Appropriate.Tools.or.Equipment)—Were.the.appro-
priate.tools.or.equipment.available.and.properly.designed?
.
3.. Knowledge.(Know-How)—Did.the.person.know.how.to.do.the.job.as.it.was.
supposed.to.be.done?
.
4.. Capacity. (Physical. Condition/Impairment)—Did. the. task. exceed. the.
capacity?
.
5.. Incentive. (Reward. or. Punishment)—Has. the. person. been. rewarded. for.
doing.the.job.incorrectly.or.punished.for.doing.it.right?
