Produced by the Truss
Plate Institute
(TPI) and SBCA, BCSI is the truss industry's guide for jobsite safety and truss performance. This 8.5" x
11" edition (3-hole punched and spiral bound) includes
the most current information regarding the handling, installation, restraining
and bracing of metal plate connected wood trusses.
This edition provides updated guidance to framing crews on how to assess fall hazards while installing trusses on residential construction jobsites and highlights additional fall protection requirements under OSHA’s new standards. BCSI also includes information and guidance pertaining to diagonal bracing for web members with two rows of lateral restraint, as well as permanent lateral restraint and diagonal bracing guidance for trusses spaced wider than two feet on center.

Additional Loading
This tag indicates the truss has been designed to support heavier loads in
this particular location (e.g., attic frame floors, rooftop mechanical
units, storage loads). See the SBCA
Online Catalog or print the Truss
Tag Flyer for
more information. |
 |
Bearing Location
Place this tag at points where additional or interior bearing supports should be located. See the SBCA Online Catalog or print the Truss Tag Flyer for more information.
Replaces TPI's orange Bearing Location tag. |
|
Concentrated Load
Place this tag at the spot where a truss is to support a concentrated or point load. See the SBCA Online Catalog or print the Truss Tag Flyer for more information.
Replaces TPI's green Concentrated Load tag. |
 |
Permanent Lateral Bracing
This tag indicates that one or two lateral braces (and diagonals) may be required on the tagged member. See the SBCA Online Catalog or print the Truss Tag Flyer for more information.
Replaces TPI's green Permanent Lateral Bracing tag. |
 |
Fall Protection
This tag warns that trusses by themselves are NOT to be used as fall protection anchors and refers the installer to BCSI-B11 for more information on fall protection issues. See the SBCA Online Catalog or print the Truss Tag Flyer for more information. |
 |
Do Not Cut, Drill or Alter
This tag emphasizes that trusses should not be cut or modified in any way. See the SBCA Online Catalog or print the Truss Tag Flyer for more information.
