Job.Safety.Analysis,.commonly.known.as.JSA.and.also.called.Job.Hazard.Analysis.
(JHA),.is.a.process.used.to.determine.the.hazards.of,.and.safe.procedures.for,.each.
step.of.a.job..A.speciic.job,.or.work.assignment,.can.be.separated.into.a.series.of.
relatively.simple.steps..The.hazards.associated.with.each.step.can.be.identiied.and.
solutions.can.be.developed.to.control.each.hazard.
PerFormIng A jsA/jhA
To.perform.a.JSA/JHA,.the.following.question.should.be.asked:
•.
What.can.go.wrong?
•.
What.are.the.consequences?
•.
How.could.it.happen?
•.
What.are.the.contributing.factors?
•.
How.likely.is.it.that.the.hazard.will.occur?
The.answers.to.these.questions.will.help.in.hazard.identiication..Some.of.the.other.
accident.speciic.questions.are
•.
Can.any.body.part.get.caught.in.or.between.objects?
•.
Do.tools,.machine,.or.equipment.present.any.hazards?
•.
Can.the.worker.make.harmful.contact.with.moving.objects?
•.
Can.the.worker.slip,.trip,.or.fall?
•.
Can.the.worker.suffer.strain.from.lifting,.pushing,.or.pulling?
•.
Is.excessive.noise.or.vibration.a.problem?
•.
Is.the.worker.exposed.to.extreme.heat.or.cold?
•.
Is.there.danger.from.falling.objects?
•.
Is.lighting.a.problem?
•.
Can.weather.conditions.affect.safety?
•.
Is.harmful.radiation.a.possibility?
•.
Can.contact.be.made.with.hot,.toxic,.or.caustic.substances?
•.
Are.there.dusts,.fumes,.mists,.or.vapors.in.the.air?
Four BAsIc stePs oF A jsA/jhA
JSA/JHA.involves.four.basic.steps:
.
1.. Select.a.job.to.be.analyzed.
.
2.. Separate.the.job.into.its.basic.steps.
.
3.. Identify.the.hazards.associated.with.each.step.
.
4.. Control.each.hazard.
Looking.at.these.four.steps.in.detail.will.help.explain.the.process.and.value.of.this.
type.of.analysis.
