__ NBBJ <br /> An�ilenuie Uesipn Plonninp <br /> April I, 1993 <br /> Mr. leffrey S. McFall <br /> Associate Engineer/Building <br /> Everett Public Works <br /> 3200 Cedar Street <br /> Everett, WA 98201 <br /> Subject: Everett Community Theater <br /> Permit No. B 36220 <br /> ; Catwalk Railings and Ladder Openings <br /> '' � Dearleff: <br /> { <br /> 'itiis is in response ro the Inspection Report of 3-18-93 and the Joe Kozlovski memo of Mazch 30, <br /> 1993, regarding the opening between rails on the stage side of catwalks and the opening <br /> protection of ladder wells. <br /> We designed the rail opening height at 32 inches clear, about the minimum allowed for the <br /> hanging of stage lighting fixtures. 1'hose on the Bagley Wright Theater are 32 and 42 inches <br /> clear. They do not use safety harnesses, but this can be done on the Everett'Rieater if required. <br /> That is a management responsibility. This comment was also discussed with our'Rieater <br /> Consultants and they concurred that this spacing of rails is standard practice. [t is the only way <br /> the lights can work and the operators can align and set them. 'Ihey also have heard of no safety <br /> problems related to this. The rai!'sng away from the stage is protected by grille cloth on frames. <br /> The ladder wells at the side lighting platforms were designed to our interpreta'tion of WISHA. <br /> See attached copy of the related WISHA section on floor openings. We have guardrails on three <br /> sides of the opening, "so offset that a person cannot walk directly into the opening." We added <br /> the latching chain as an additional deterrent. No work occurs opposite the opening, so passage <br /> by or to the ladder is the only activiry. <br /> As shown on the attached plan, an outswinging gate could be only two feet wide. We felt <br /> restricting the step-0ff width tolfrom the ladder to this width could be a hazard. We also believe <br /> that if more than one chain is provided, only one would be secured. Leaning over in the two foot <br /> passage to secure lower chains would be difficult. <br /> • <br /> Aiirona (alilo�nia New Yoi1 Noit� (a�olino OM1io Woshinqton <br /> III Sou'h lahton Sbat SeoMe,WasM1irqion 9810/ f206177?5555 Fm R0616P1�7300 <br />
