through.holes.(including.skylights),.by.using.covers.
Also,.workers.on.ramps,.runways,.and.other.walkways.must.be.protected.from.

of. an. excavation. 4. feet. or. more. in. depth. must. be. protected. from. falling. by. using.
guardrail.systems,.fences,.or.barricades.
Workers.less.than.4.feet.above.dangerous.equipment.must.be.protected.from.fall-
ing.into.or.onto.the.dangerous.equipment.by.the.use.of.guardrail.systems.or.equip-
ment. guards.. When. workers. are. 4. feet. or. more. above. dangerous. equipment,. they.
must.be.protected.from.fall.hazards.by.using.guardrail.systems,.personal.fall.arrest.
systems,.or.safety.net.systems.
Workers.engaged.in.rooing.activities.on.low-slope.roofs,.with.unprotected.sides.

Each. employee. working. on,. at,. above,. or. near. wall. openings. (including. those.
with.chutes.attached),.where.the.outside.bottom.edge.of.the.wall.opening.is.4.feet.or.
more.above.lower.levels.and.the.inside.bottom.edge.of.the.wall.opening.is.less.than.
39.inches.above.the.walking.or.working.surface,.must.be.protected.from.falling.by.
using.a.guardrail.system,.safety.net.system,.or.personal.fall.arrest.system.
When. workers. are. exposed. to. falling. objects,. the. employer. must. have. each.
employee.wear.a.hard.hat.and.implement.one.of.the.following.measures:
•. Erect.toeboards,.screens,.or.guardrail.systems.to.prevent.objects.from.fall-
ing.from.higher.levels.
•. Erect.a.canopy.structure.and.keep.potential.fall.objects.far.enough.from.the.
edge.of.the.higher.level.so.that.those.objects.would.not.go.over.the.edge.if.
they.were.accidentally.displaced.
•. Barricade. the. area. to. which. objects. could. fall;. prohibit. employees. from.
entering. the. barricaded. area;. and. keep. objects. that. may. fall. far. enough.
away.from.the.edge.of.a.higher.level.so.that.those.objects.would.not.go.over.
the.edge.if.they.were.accidentally.displaced.
The.most.common.fall.protection.systems.are
•.
Guardrails
•.
Safety.nets
•.
Personal.fall.arrest.systems
