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. |
