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.
