(1) Pulp and paper machines must be equipped
with emergency stopping control(s) which can be actuated quickly from all
normal operating stations. If useful for the safety of personnel, the stopping
control(s) must be interlocked with adequate retarding or braking action to
stop the machine as quickly as is practical. The devices must consist of push
buttons for electric motive power (or electrically operated engine stops), pull
cords connected directly to the prime mover, control clutches, or other
devices.
(2) Steps and footwalks
along the fourdrinier/forming and press section must have nonslip surfacing and
be complete with standard handrails, when practical.
(3) If a machine must be lubricated while in
operation an automatic lubricating device must be provided or oil cups and
grease fittings must be provided which can be serviced safely without exposing
the worker to any hazards.
(4) All
levers carrying weights must be so constructed that weights will not slip or
fall off.
(5) Guarding inrunning
nip points. The drums on pulp and paper machine winders must be provided with
suitable guards to prevent a person from being caught between the roll and the
front drum on the winder when the pinch point is on the operator's side.
(a) Such guards must be interlocked with the
drive mechanism to prevent the winder from running while the guard is not in
place. Except that the winder may be wired to allow it to run at thread or jog
speed only for adjustment and start up purposes while the guard is not in
position.
(b) A zero speed switch
or locking device must be installed to prevent the guard from being removed
while the roll is turning above thread or jog speed.
(c) Rewinders.
When rewinding large rolls and the nip point is adjacent to the
normal work area)):
(i) The nip point
must be protected by a barrier guard ;
(ii) Such guard must be interlocked with the
drive mechanism to prevent operating the machine above thread or jog speed
without the guard in place; and
(iii) A zero speed switch must be installed
to prevent the guard from being raised while the roll is turning.
(d) Inrunning nips where paper is
not being fed into a calender must be guarded.
(6) An audible alarm must be sounded prior to
starting up any section of a pulp or paper machine. Sufficient time must be
allowed between activation of the alarm system and start up of the equipment to
allow any persons to clear the hazardous area.
(7) When starting up a dryer section, steam
to heat the drums must be introduced slowly and while the drums are
revolving.
(8) A safe method must
be used when starting paper into the nip of drum type reels or calender stacks.
This may be accomplished by the use of feeder belts, carrier ropes, air
carriage or other device or instrument.
(a) A
rope carrying system should be used wherever possible at points of transfer;
or
(b) Sheaves should be spaced so
that they do not create a nip point with each other and the sheave and its
support should be capable of withstanding the speed and breaking strength of
the rope for which they are intended.
(9) Employees must not feed a stack with any
hand held device which is capable of going through the nip.
(10) Employees must not attempt to remove a
broken carrier rope from a dryer while the section is running at operating
speed.
(11) Employees must stop the
dryer to remove a wrap except in cases where it can be safely removed by using
air or other safe means.
(12) To
remove deposits from rolls, a specially designed scraper or tool must be used.
Scraping of rolls must be performed on the outgoing nip side.
(13) Doctor blades.
(a) Cleaning. Employees must not place their
hands between the sharp edge of an unloaded doctor blade and the roll while
cleaning the doctor blade.
(b)
Doctor blades must have the sharp edges properly guarded during transportation
and storage.
(c) Special protective
gloves must be provided and must be worn by employees when filing or handling
sharp edged doctor blades.
(14) Handling reels.
(a) Reels must stop rotating before being
lifted away from reel frame.
(b)
Crane hooks must not be used to stop a turning reel.
(c) Exposed rotating reel shafts with square
block ends must be guarded.
(d) The
crane operator must ascertain that reels are properly seated at winder stand or
at reel arms before they disengage the hooks.
(e) On stored reels, a clearance of at least
8 inches between the reels of paper must be maintained.
(15) All winder shafts must be equipped with
a winder collar guide. The winder must have a guide rail to align the shaft for
easy entrance into the opened rewind shaft bearing housing. If winder shafts
are too heavy for manual handling, mechanical equipment must be used.
(16) Shaftless winders must be provided with
a barrier guard of sufficient strength and size to confine the rolls in the
event they become dislodged while running.
(17) All calender stacks and spreader bars
must be grounded according to chapter
296-24 WAC, Part L, and WAC
296-800-280 as protection against
shock induced by static electricity.
(18) Nonskid type surface required.
(a) All exposed sole plates between dryers,
calenders, reels, and rewinders must have a nonskid type surface.
(b) A nonskid type surface must be provided
in the work areas around the winders or rewinders.
(19) If a powered roll ejector is used it
should be interlocked to prevent accidental actuation until the receiving
platform or roll lowering table is in position to receive the roll.
(20) Employees must keep clear of hazardous
areas around the lowerator, especially all lowerator openings in a floor and
where roll is being discharged.
(21) Provision must be made to hold the rider
roll when in a raised position unless counterbalancing eliminates the
hazard.
(22) Drain openings in
pits. Flush floor drain openings larger than 3 inches in diameter in the bottom
of pits must be guarded to prevent workers from stepping through, while working
in this area.
(23) Employees must
not enter into or climb on any paper machine roll that is subject to free
turning unless a positive locking device has been installed to prevent the roll
from turning.
(24) You must ensure
sufficient inspection and nondestructive examination of reel spool and calender
roll journals. The type and frequency of testing must be adequate to detect
indications of failure. Any reel spool or calender roll journal found to have
an indication of failure must be removed from service. Nondestructive
examination personnel must be qualified in accordance with SNT-TC 1A.
