5.. Phases. and. speciic. operations. of. the. project. that. will. require. further.
analyses.are.those.that.have.a.complexity.of.potential.hazards.or.unusual.
activities. involved;. those. where. there. may. be. uncertainty. concerning. the.
worksite's.condition.at.the.time.of.project;.or.those.where.there.is.concern.
for.methods.that.will.be.used.to.complete.a.phase.or.operation
A. phase. hazard. analysis. may. be. performed. for. those. phases. of. the. project. for.
which.the.project.hazard.analysis.has.identiied.the.need.for.further.analysis,.and.for.
those.phases.of.the.project.for.which.methods.or.site.conditions.have.changed.since.
the.project.hazard.analysis.was.completed..The.phase.hazard.analysis.is.performed.
prior. to. the. start. of. work. on. that. phase. of. the. project. and. is. expanded,. based. on.
the.results.of.the.project.hazard.analysis,.to.provide.a.more.thorough.evaluation.of.
related.work.activities.and.site.conditions..As.appropriate,.the.phase.hazard.analysis.
should.include
.
1.. Identiication.of.the.speciic.work.operations.or.procedures
.
2.. An.evaluation.of.the.hazards.associated.with.the.speciic.chemicals,.equip-
ment,.materials,.and.procedures.used.or.present.during.the.performance.of.
that.phase.of.work
.
3.. An. evaluation. of. how. safety. and. health. has. impacted. any. changes. in. the.
schedule;. and. how. work. procedures. or. site. conditions. that. have. occurred.
since.performance.of.the.project.hazard.analysis.need.to.be.completed
.
4.. Identiication. of. speciic. control. measures. necessary. to. protect. workers.
from.the.identiied.hazards
.
5.. Identiication.of.speciic.operations.for.which.protective.measures.or.proce-
dures.must.be.designed,.supervised,.approved,.or.inspected.by.a.registered.
professional.engineer.or.competent.person
A.job.safety.assessment.or.analysis.should.be.performed.at.the.start.of.any.task.
or. operation.. The. designated. competent. or. authorized. person. should. evaluate. the.
task.or.operation.to.identify.potential.hazards.and.determine.the.necessary.controls..
This.assessment.should.focus.on.actual.worksite.conditions.or.procedures.that.differ.
from.or.were.not.anticipated.in.the.related.project.or.phase.hazard.analysis..In.addi-
tion,.the.authorized.person.should.ensure.that.each.employee.involved.in.the.task.or.
operation.is.aware.of.the.hazards.related.to.the.task.or.operation.and.of.the.measures.
or.procedures.that.workers.and.visitors.must.use.to.protect.themselves..Note:.The.job.
safety.assessment.is.not.intended.to.be.a.formal,.documented.analysis,.but.instead.is.
more.of.a.quick.check.of.actual.site.conditions.and.a.review.of.planned.procedures.
and.precautions..A.more.detailed.explanation.of.job.safety.analysis.is.provided.in.
