WAC 296-874-20012. Meet these requirements when using shorter platforms to create a longer platform

(1) You must make sure, when platforms are overlapped to create a longer platform, that: (a) The overlap is over a support; (b) The platforms are either: (i) Overlapped by at least twelve inches (30 cm); or (ii) Are nailed together or otherwise prevented from moving. (2) You must make sure, when platforms are butted together to create a longer platform, that each abutted platform end rests on a separate support surface. Note: Platforms may butt together on a common support member if the member is designed to support abutting platforms, such as either: 1. A "T" section; or 2. Hook-on platforms designed to rest on common supports.
