- Structures may also be designed using a combination of both prescriptive and engineered methods as indicated in IBC Section 2308.1.
- Structures may be designed within the prescriptive requirements of Section 2308. Limitations can be found in the sidebar on page 25.

- The Western Lumber Grading Rules permit combinations of like-named U.S. and Canadian species groups, which allows mills that have access to logs from the U.S. and Canada to mix them during production.
- The most common combinations are Douglas Fir-Larch, Hem-Fir and Spruce-Pine-Fir.
- The applicable design values for a given U.S. and Canadian species group combination that component manufacturers should use in their software are the lower of the two individual country values for each design value category (see Table 2 on page 76).

- If an injury or illness resulted from an event or "exposure" that happened at work, assume it is work related.
- There are some exemptions to what is defined as work related, such as an employee using company property for personal tasks outside his/her assigned work hours.
- A fatality is ALWAYS recordable.

- Generally, wall girders cannot be used in second story framing because it is nearly impossible to brace the compression top chord of a girder when it is placed in a wall.
- The top chord(s) of girder trusses can experience very high compressive forces, which can cause the chord to buckle out of plane.
