the.building..No.open.lames,.spark-producing.devices,.or.heated.surfaces.having.a.
temperature.suficient.to.ignite.vapors.in.any.lammable.vapor.should.exist..Areas.in.
the.vicinity.of.dip.tanks.must.be.kept.clear.of.combustible.stock.as.is.practical.and.
must.be.kept.entirely.free.of.combustible.debris.
All. dip. tanks. exceeding. 150. gallons. of. lammable. liquid. capacity. or. having. a.
liquid. surface. area. exceeding. 4. square. feet. must. be. protected. with. at. least. one. of.
the.following.automatic.extinguishing.facilities:.water.spray.system,.foam.system,.
carbon.dioxide.system,.dry.chemical.system,.or.automatic.dip.tank.cover.
dockBoArds (29 cFr 1910.30)
Dockboards.must.be.strong.enough.to.carry.the.load.imposed.upon.them..Portable.
dockboards.must.be.anchored.or.equipped.with.devices.that.will.prevent.their.slip-
ping..Handholds.should.exist.on.dockboards.that.provide.a.safe.and.effective.means.
of. being. able. to. handle. them.. Railroad. cars. should. be. provided. with. mechanisms.
that.would.prevent.movement.while.dockboards.are.being.used.
drInkIng WAter (29 cFr 1910.141)
Potable.drinking.water.must.be.provided.in.all.places.of.employment..Potable.drink-
ing.water.dispensers.must.be.designed,.constructed,.and.serviced.to.ensure.sanitary.
conditions,.capable.of.being.closed,.and.have.a.tap..Open.containers.such.as.barrels,.
pails,.or.tanks.for.drinking.water.from.which.the.water.must.be.dipped.or.poured,.
whether.or.not.they.are.itted.with.a.cover,.are.prohibited..A.common.drinking.cup.
is.not.allowed.

1910.305, 1910.331, And 1910.333)
Electricity. is. accepted. as. a. source. of. power. without. much. thought. to. the. hazards.
encountered..Some.employees.work.with.electricity.directly,.as.is.the.case.with.engi-
neers,.electricians,.and.people.who.work.with.wiring,.such.as.overhead.lines,.cable.
harnesses,. or. circuit. assemblies.. Others,. such. as. ofice. workers. and. salespeople,.
work.with.electricity.indirectly..Approximately.700.workers.are.electrocuted.each.
year,.with.many.workers.suffering.injuries.such.as.burns.and.cuts.
OSHA's. electrical. standards. address. the. government's. concern. that. electricity.
has. long. been. recognized. as. a. serious. workplace. hazard.. Beyond. burns. and. cuts,.
employees. are. subject. to. such. dangers. as. electric. shock,. electrocution,. ires,. and.
explosions..The.objective.of.these.standards.is.to.minimize.such.potential.hazards.
by.specifying.design.characteristics.of.safety.approaches.and.designs.in.the.use.of.
electrical.equipment.and.systems.
Electrical.equipment.must.be.free.from.recognized.hazards.that.are.likely.to.cause.
death. or. serious. physical. harm. to. employees.. Flexible. cords. and. cables. (extension.
cords).should.be.protected.from.accidental.damage..Unless.speciically.permitted,.
lexible. cords. and. cable. may. not. be. used. as. a. substitute. for. the. ixed. wiring. of. a.
