In-Depth Information
It. is. important. that. the. JSA/JHA. accurately. describe. the. work.. There. may. be.
some.disagreement.about.basic.job.steps..Some.may.think.that.checking.luid.levels.
is. part. of. the. walk-around. inspection—and. on. some. machines. this. may. be. true..
However,. on. other. machines,. checking. luid. levels. presents. an. entirely. new. set. of.
hazards.that.may.be.overlooked.if.grouped.with.the.general.walk-around.inspection..
Such. hazards. include. working. from. an. elevated. position. and. coming. into. contact.
with.hot.luids.or.surfaces..Keep.in.mind.that.a.JSA/JHA.that.is.too.broad.is.also.a.
poor.JSA/JHA.

After.all.basic.steps.of.the.operation.of.a.piece.of.equipment.or.job.procedure.have.
been.listed,.each.job.step.should.be.examined.to.identify.hazards.associated.with.it..
The.purpose.is.to.identify.and.list.the.hazards.that.are.possible.in.each.step.of.the.
job..Some.hazards.are.more.likely.to.occur.than.others,.and.some.are.more.likely.
to. produce. serious. injuries. than. others.. Consider. all. reasonable. possibilities. when.
identifying.hazards.
To.make.this.task.manageable.work.with.the.basic.types.of.accidents,.the.question.
to.ask.is:.“Can.any.of.these.accident.types.or.hazards.inlict.injury.on.a.worker?”.
There.are.eleven.basic.types.of.accidents:
.
1.. Struck-against
.
2.. Struck-by
.
3.. Contact-with
.
4.. Contacted-by
.
5.. Caught-in
.
6.. Caught-on
.
7.. Caught-between
.
8.. Fall-same-level
.
9.. Fall-to-below
.
10.. Overexertion
.
11.. Exposure
Look.at.each.of.these.basic.accident.types.in.more.detail..Analyze.each.job.step.
(irst.column.of.the.JSA/JHA.form.in.Table 12.1).separately;.look.for.only.one.kind.
of.hazard.or.accident.at.a.time.

Look.at.these.irst.four.basic.accident.types.(struck-against,.struck-by,.contact-with,.
and. contacted-by). in. more. detail,. keeping. the. job. step. walk-around. inspection. in.
mind..Can.the.worker.strike.against.anything.while.doing.the.job.step?.Think.of.the.
worker. moving. and. contacting. something. forcefully. and. unexpectedly. (an. object.
capable.of.causing.injury)..Can.he.or.she.forcefully.contact.anything.that.will.cause.
injury?. This. forceful. contact. may. be. with. machinery,. timber. or. bolts,. protruding.
objects,.or.sharp,.jagged.edges..Identify.not.only.what.the.worker.can.strike.against,.
