Wash. Admin. Code § 296-301-04501 - Cylinder dryers
(1) Reducing
valves, safety valves, and pressure gages must conform to the ASME Pressure
Vessel Code, section VIII, Unfired Pressure Vessels, 1968.
(2) Vacuum relief valves must conform to the
ASME Code for Pressure Vessels, section VIII, Unfired Pressure Vessels,
1968.
(3) Lever control. When
slashers are operated by control levers, these levers must be connected to a
horizontal bar or treadle located not more than 69 inches above the floor to
control the operation from any point.
(4) Pushbutton control. Slashers operated by
pushbutton control must have stop and start buttons located at each end of the
machine, and additional buttons located on both sides of the machine, at the
size box and the delivery end. If calender rolls are used, additional buttons
must be provided at both sides of the machine at points near the nips, except
when slashers are equipped with an enclosed dryer.
(5) Nip guards. All nip guards must comply
with the requirements of WAC
296-301-04503(4).
(6) Cylinder enclosure. When enclosures or
hoods are used over cylinder drying rolls, such enclosures or hoods must be
provided with an exhaust system which will effectively prevent wet air and
steam from escaping into the workroom.
(7) Expansion chambers. Slasher kettles and
cookers must be provided with expansion chambers in the covers, or drains, to
prevent surging over. Steam-control valves must be so located that they can be
operated without exposing the worker to moving parts, hot surfaces, or
steam.
