WAC 296-874-20006. Maintain structural integrity when intermixing scaffold components

(1) You must make sure intermixed scaffold components: (a) Fit together without force; and (b) Maintain the scaffold's structural integrity. (2) You must make sure a qualified person determines that modifying components in order to intermix them will result in a structurally sound scaffold. (3) You must make sure scaffold components made of different metals are not used together. EXEMPTION: Different types of metals may be used together if a competent person determines that galvanic action will not reduce the strength of any component to less than the minimum strength required. Reference: The minimum strength requirements are found in the following sections: 1. Suspended scaffolds, WAC 296-874-30002 ; 2. Supported scaffolds, WAC 296-874-40002 .
