- A common mistake is thinking that the truss design drawing provides all of the bracing requirements for the truss.
- In the 2006 Edition of BCSI continuous lateral brace has been replaced in by the term “continuous lateral restraint.”
- Bracing the lateral restraint is critical for ensuring truss stability; failure to do so can result in serviceability problems or structural collapse.

- Solar panels—devices that convert solar energy into electricity or heat—are often installed in trussed and conventionally framed roofs.
- To determine if a truss can withstand the load of a solar panel, add the value of the panel to the maximum top chord dead load capacity.
- If a panel can be applied to a conventionally framed roof with the same design load capacity as a truss system, the application should also work in the trussed roof.

- The IRC 2006 references BCSI 1-03 in two locations—R502.11.2 and R802.10.3.
- In 2006, BCSI 1-03 was revised and retitled Building Component Safety Information; Guide to Good Practice for Handling, Installing, Restraining & Bracing of Metal Plate Connected Wood Trusses.
- Although BCSI 1-03 is referenced in IRC 2006, you should use the most recent version of the booklet—BCSI.

- OSHA’s Top Ten list is a great place to start for reviewing safety issues at your facility.
- Three of the 2006 Top Ten (one, three and nine) fall under OSHA’s Safety and Health Regulations for Construction (Part 1926) and don’t apply to component manufacturing.
- The remaining seven violations relate to standards that are important to comply with as a component manufacturer.
