(a) Guarding in Machine Rooms and Machinery
Spaces. The following equipment located in machine rooms or machinery spaces
shall be guarded to protect against accidental contact:
(1)
Exposed external moving parts
such as gears, sprockets, sheaves, drums, shafts and their driving ropes,
chains or tapes for selectors, floor controllers or signal machines.
EXCEPTION to subsection
3014(a)(1):
Guards are not required for equipment located more than
7 ft (2.13m) above the floor.
(2) The nip points of the drive sheave of
traction machines where the machine frame does not provide this
protection.
(3)
All moving
parts of the equipment in secondary sheave spaces shall be completely guarded
except the governor sheave and flyballs. Expanded metal or grillwork
shall be used for secondary sheave guards.
EXCEPTION: Guards are not required for equipment
located more than 7 ft (2.13m) above the secondary sheave space
floor.
(4) The moving parts
of equipment in overhead sheave spaces having a ceiling height of less than 78
in. (1.98m) shall be completely guarded except the governor sheave and
flyballs.
(5) The moving parts of
equipment in overhead sheave spaces shall be guarded when it is necessary to
pass over or by the moving parts to gain access to the
governor.
(b) Guarding in
the Hoistway and On the Car. The following equipment located in the elevator
hoistway or on the elevator car shall be guarded to protect against accidental
contact:
(1) Hoisting rope sheaves attached
to and mounted above the car crosshead shall be completely guarded. Handholds
shall be provided on each side of the guard.
(2) Hoisting rope sheaves mounted within the
car crosshead shall be provided with guards at the exposed nip
points.
(3) Where secondary or
deflecting sheaves are located on the hoisting side of overhead machines, the
ropes shall be guarded at the point of contact with the sheave, except where
the bottom of the sheave is more than 7 ft (2.13m) above the crosshead of the
car when the car is at the top terminal landing.
(4) Where overhead sheaves are located above
the crosshead, the ropes attached to the crosshead shall be guarded at the
point of contact with the overhead sheave unless the sheave is located in an
overhead sheave space.
(5)
Ventilating fans or blowers installed on the car top shall be
guarded.
(c)
Rope Retainer Guards. Rope retainer guards shall be provided on deflector
sheaves, machine sheaves, compensator rope sheaves,
governor tension
sheaves and hoist rope sheaves on cars and counterweights to inhibit
displacement of ropes in the event ropes become slack.
Rope guards shall be continuous or there shall
be one restraint for 30 degrees wrap or less, and two restraints for wraps in
excess of 30 degrees. Where one restraint is furnished, it shall divide the arc
of contact into equal parts. Where two restraints are furnished, they shall be
located approximately
1/6 of
the arc of contact from the nip points.
(d) Snag Guards. Snag points created by rail
brackets, clip bolts and fishplates shall be provided with guards to prevent
snagging of the following:
(1)
Compensating cables on the counterweight end within 30 in. (762mm) of a
counterweight rail bracket.
(2)
Governor ropes located within 20
in. (510mm) of a counterweight rail bracket.
(3)
Hoist ropes located within 12 in.
(305mm) of a snag point.
(4)
Traveling cables hung so any
portion of their loop below the hatch junction box is within 36 in. (914mm)
horizontally of a potential snag point.
