chAnge joB Procedures
If.the.sequence.of.job.steps.or.the.deviations.from.established.job.steps.are.critical.to.
the.safe.performance.of.a.job,.this.should.be.noted.in.the.JSA/JHA.
The. next. part. of. the. JSA. process. is. to. develop. the. “Recommended. Safe. Job.
Procedure”.to.eliminate.or.reduce.potential.accidents.or.hazards.that.have.been.iden-
tiied..(This.is.the.third.column.in.Table 12.1.).The.following.four.points.should.also.
be.considered.for.each.hazard.identiied.for.the.job.step:
.
1.. Can.a.less.hazardous.way.to.do.the.job.be.found?
.
2.. Can.an.engineering.revision.take.place.to.make.the.job.or.work.area.safer?
.
3.. Is.there.a.better.way.to.do.the.job?.This.requires.determining.the.work.goal.
and.then.analyzing.various.ways.to.reach.the.goal.to.see.which.way.is.safest.
.
4.. Are.there.work-saving.tools.and.equipment.available.that.can.make.the.job.
safer?
What. to. consider. with. this. group. of. questions. is. how. the. equipment. and. work.
area.can.be.changed,.or.provided.with.additional.tools.or.equipment,.to.make.the.job.
safer..An.example.of.an.engineering.revision.to.a.machine.could.be.to.modify.both.
the. ladders. and. platform. on. it. with. some. type. of. anti-slip. surface.. An. example. of.
adding.a.work-saving.tool.might.be.to.purchase.special.hand.trucks.for.use.in.a.shop.
or.an.area.where.ifty-ive-gallon.drums.are.now.moved.by.hand.
If.a.new,.less.hazardous.way.to.do.the.job.cannot.be.found,.physical.conditions.
should.be.studied.carefully.

Can.the.physical.conditions.that.created.the.hazard.be.changed?.Physical.conditions.
may.be.tools,.materials,.and.equipment.that.may.not.be.right.for.the.job..These.con-
ditions.can.be.corrected.by.either.engineering.revisions.or.administrative.revisions,.
or.a.combination.of.both.
As.an.example.of.changing.physical.conditions,.consider.the.following.scenario:.
A. company. had. several. injuries. while. putting. lime. into. a. new. hopper. in. a. water.
treatment. plant.. Upon. investigation. it. was. found. that. the. hopper. opening. is. 5. feet.
off.the.loor.and.the.lime.is.packaged.in.100-pound.bags..An.administrative.revision.
may.be.to.purchase.50-pound.bags.of.lime;.and.an.engineering.revision.would.be.to.
build.a.platform.and.steps.so.that.the.bags.would.only.have.to.be.lifted.waist-high..
Obviously,.a.combination.of.both.of.these.would.be.the.best.solution.
