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. |
