Leggings. are. used. to. protect. the. lower. legs. and. feet. from. heat. hazards. such.
as. molten. metal. or. welding. sparks.. Safety. snaps. allow. for. quick. removal. of. the.
leggings.. Metatarsal. guards. are. made. of. aluminum,. steel,. iber,. or. plastic;. these.
guards.may.be.strapped.to.the.outside.of.shoes.to.protect.the.instep.area.from.impact.
and..compression..Toe.guards.may.be.made.of.steel,.aluminum,.or.plastic..They.it.
over.the.toes.of.regular.shoes.and.protect.only.the.toes.from.impact.and.compression.
hazards.. Combination. foot. and. shin. guards. may. be. used. in. combination. with. toe.
guards.when.greater.protection.is.needed.
Sturdy.safety.shoes.should.have.impact-resistant.toes.and.heat-resistant.soles.to.
protect.against.hot.work.surfaces.common.in.rooing,.paving,.and.hot.metal.indus-
tries..The.metal.insoles.of.some.safety.shoes.protect.against.puncture.wounds..Safety.
shoes.may.also.be.designed.to.be.electrically.conductive.to.prevent.the.buildup.of.
static. electricity. in. areas. with. the. potential. for. explosive. atmospheres,. or. noncon-
ductive.to.protect.workers.from.workplace.electrical.hazards..All.safety.shoes.must.
comply.with.the.ANSI.standard(s).mentioned.above..In.addition,.depending.on.the.
types.of.worker.exposures,.there.may.be.a.need.to.provide.specially.designed.safety.
shoes.such.as.conductive.or.electrical-hazard.safety.shoes.
Electrically. conductive. shoes. protect. against. the. buildup. of. static. electricity..
Essentially,.these.shoes.ground.the.employees.who.are.wearing.them..Employees.
working. in. explosive. and. hazardous. locations. such. as. explosives. manufactur-
ing. facilities. or. grain. elevators. must. wear. conductive. shoes. to. reduce. the. risk. of.
static. electricity. buildup. on. an. employee's. body. that. could. produce. a. spark. and.
cause. an. explosion. or. ire.. During. training,. employees. must. be. instructed. not. to.
use.foot..powder.or.wear.socks.made.of.silk,.wool,.or.nylon.with.conductive.shoes..
Foot. .powder. insulates. and. retards. the. conductive. ability. of. the. shoes.. Silk,. wool,.
and.nylon.produce.static.electricity..Conductive.shoes.are.not.general-purpose.shoes.
and. must. be. removed. upon. completion. of. the. tasks. for. which. they. are. required..
Employees.exposed.to.electrical.hazards.must.never.wear.conductive.shoes.
Electrical.hazard,.safety-toe.shoes.are.nonconductive.and.will.prevent.employees'.
feet.from.completing.an.electrical.circuit.to.the.ground..They.can.protect.employ-
ees. against. open. circuits. of. up. to. 600. volts. in. dry. conditions.. Electrical. hazard,.
safety-toe.shoes.should.be.used.in.conjunction.with.other.insulating.equipment.and.
precautions. to. reduce. or. eliminate. the. potential. for. employees'. bodies. or. parts. of.
their.bodies.to.provide.a.path.for.hazardous.electrical.energy..Note:.Nonconductive.
footwear. must. not. be. used. in. explosive. or. hazardous. locations;. in. such. locations,.
electrically. conductive. shoes. are. required.. Train. employees. to. recognize. that. the.
insulating.protection.of.electrical.hazard,.safety-toe.shoes.may.be.compromised.if
•.
The.shoes.are.wet.
•.
The.rubber.soles.are.worn.through.
•.
Metal.particles.become.embedded.in.the.soles.or.heels.
•.
Other. parts. of. the. employees'. bodies. come. into. contact. with. conductive,.
grounded.items.
In.addition.to.insulating.employees'.feet.from.the.extreme.heat.of.molten.metal,.
foundry. shoes. prohibit. hot. metal. from. lodging. in. shoe. eyelets,. tongues,. or. other.
