These. four. assumptions. place. physical. barriers. in. proper. perspective.. While.
stressing.their.importance,.their.limitations.are.also.deined..In.order.to.perform.a.
physical.barrier.analysis,.the.following.will.be.needed:
.
1.. Accident.information
.
2.. Groups.of.physical.barrier.analysis.statements
.
3.. A.physical.barrier.analysis.matrix
.
4.. Instructions
.
5.. Familiarity.with.the.practices,.procedures,.methods,.and.strategies.of.the.
industrial.operation.being.analyzed
Using.the.company's.accident.investigation.forms,.the.irst.thing.to.do.in.analyz-
ing. the. accident. is. to. read. the. narrative. and. visualize. what. happened.. Often,. the.
report.is.sketchy,.but.most.of.the.time.you.will.be.able.to.draw.on.your.experience.
to.read.between.the.lines.and.get.the.picture..Once.you.have.visualized.the.situation.
and.what.occurred,.then.ask:.“What.could.have.prevented.this.accident?”.To.help.
determine.the.appropriate.preventive.measures,.make.use.of.the.list.of.physical.bar-
rier.analysis.statements..The.following.statements.refer.to.each.of.the.four.types.of.
physical.barriers..For.each.type,.there.are.four.possibilities..Select.the.one.that.best.
represents.a.valid.opinion.of.the.accident.
.
1.. A.physical.barrier.on.the.energy.source.was:
.
(Prevent.Release)
.
A.. Not.possible.and.practical.
.
B.. Practical.and.possible,.but.not.provided.
.
C.. Provided,.but.not.used.
.
D.. Used,.but.failed.
.
2.. A.physical.barrier.between.the.energy.source.and.the.person.was:
.
(Prevent.Contact)
.
A.. Not.possible.and.practical.
.
B.. Practical.and.possible,.but.not.provided.
.
C.. Provided,.but.not.used.
.
D.. Used,.but.failed.
.
3.. A.physical.barrier.on.the.person.was:
.
(Prevent.Forcefulness)
.
A.. Not.possible.and.practical.
.
B.. Practical.and.possible,.but.not.provided.
.
C.. Provided,.but.not.used.
.
D.. Used,.but.failed.
.
4.. A.barrier.of.time.or.space.between.the.energy.source.and.the.person.was:
.
(Prevent.Contact)
.
A.. Not.possible.and.practical.
.
B.. Practical.and.possible,.but.not.provided.
.
C.. Provided,.but.not.used.
.
D.. Used,.but.failed.
