hAnd And Arm ProtectIon
If.the.workplace.hazard.assessment.reveals.that.employees.risk.injury.to.their.hands.
and.arms,.and.engineering.and.work.practice.controls.do.not.eliminate.such.hazards,.
then.hand.and.arm.protection.must.be.provided.to.employees..The.injuries.that.may.
need.to.be.guarded.against.in.the.workplace.include.burns,.bruises,.abrasions,.cuts,.
punctures,.fractures,.amputations,.or.chemical.exposures.
For. many. workplace. operations,. machine. guards. such. as. point-of-operation.
guards.will.be.suficient..For.example,.install.a.barrier.that.makes.it.impossible.for.
employees.to.put.their.hands.at.the.point.where.a.table.saw.blade.makes.contact.with.
the.wood.it.cuts..For.other.hazardous.operations,.employers.may.be.able.to.institute.
work.procedures.that.eliminate.the.risk.of.injury.to.employees'.hands.or.arms..When.
such. measures. fail. to. eliminate. the. hazard,. however,. protective. gloves. will. be. the.
primary.means.of.protecting.employees'.hands..When.the.risk.of.injury.includes.the.
arm,.protective.sleeves,.often.attached.to.the.gloves,.may.be.appropriate.
There.is.no.one.kind.of.glove.that.universally.protects.the.worker.from.hand.injury.
hazards..The.nature.of.the.hazard(s).and.the.operation.to.be.performed.will.determine.
the.selection.of.gloves..The.variety.of.potential.occupational.hand.injuries.may.make.
selecting. the. appropriate. pair. of. gloves. more. dificult. than. choosing. other. protec-
tive.equipment..Take.care.to.choose.gloves.designed.for.the.particular.circumstances.
of.the.particular.workplace..Gloves.are.made.from.a.wide..variety.of..materials.and.
are.designed.for.virtually.every.workplace.hazard..In.general,..however,.they.may.be.
divided.into.four.groups:
.
1.. Durable.work.gloves.made.of.metal.mesh,.leather,.or.canvas
.
2.. Fabric.and.coated.fabric.gloves
.
3.. Chemical.and.liquid.resistant.gloves
.
4.. Insulating.rubber.gloves

Sturdy.gloves.made.from.metal.mesh,.leather,.or.canvas.provide.protection.against.
cuts,.burns,.and.sustained.heat..Leather.gloves.protect.against.sparks,.moderate.heat,.
blows,.chips,.rough.objects,.and.some.low.voltage.electrical.shocks.(see.Figure 24.7)..
Welders,.in.particular,.need.the.durability.of.higher-quality.leather.gloves.
Aluminized. gloves. are. usually. used. for. welding,. furnace,. and. foundry. work.
because.they.provide.relective.and.insulating.protection.against.heat..Aluminized.
gloves.require.an.insert.made.of.synthetic.materials.that.protects.against.heat.and.
cold.. Aramid. iber. gloves. are. made. from. synthetic. material. that. protects. against.
heat.and.cold..Many.glove.manufacturers.use.aramid.iber.to.make.gloves.that.are.
cut- and.abrasive-resistant.and.wear.well.
Several.manufacturers.make.gloves.with.other.synthetic.fabrics.that.offer.protec-
tion.against.heat.and.cold..In.addition.to.protection.against.temperature.extremes,.
