- a.Sashes
- b.Structural headers
- c.Roof trusses
- d.Exterior stair stringers

A cut list has eight pieces of 1-inch stock, each 3 inches wide and 48 inches long. What is the net board footage?
- a.1 board foot
- b.96 board feet
- c.12 board feet
- d.8 board feet
Answer: d
Explanation: Each piece is 1 × 3 × 48 = 144 cubic inches, which is exactly 1 board foot, so eight pieces are 8 board feet. One board foot counts a single piece; 96 forgets to divide by 12 after converting the length to feet (1 × 3 × 4 × 8); and 12 confuses the count.

Which statement about hardwoods and softwoods is supported by the Wood Handbook?
- a.The names are botanical
- b.Hardwoods are evergreen trees
- c.Hardwoods are harder than softwoods
- d.Softwoods contain vessels; hardwoods do not
Answer: a
Explanation: The Wood Handbook explains that hardwoods are angiosperms and softwoods gymnosperms, and that some softwoods, such as longleaf pine and Douglas-fir, are harder than some hardwoods. Hardwoods, not softwoods, contain vessels, and temperate hardwoods are usually deciduous, not evergreen.

- b.HGS, horizontal general purpose
- c.HGP, horizontal postformable
- d.CLS, cabinet liner standard
Answer: d
Explanation: The guide specification describes cabinet liner standard grade, 0.020 inch, as intended for light-duty semi-exposed interior surfaces. HGS is for horizontal surfaces, VGS for exposed vertical surfaces, and HGP for postformed horizontal surfaces.

- a.No grade is specified
- b.Grade 2
- c.Grade 3
- d.Grade 1

- 6. Cabinet Installation
How long must a renovation firm keep records showing it followed the RRP rule?
- a.5 years after completing the renovation
- b.3 years after completing the renovation
- c.Until the home is sold
- d.1 year after completing the renovation
Answer: b
Explanation: Firms must keep records demonstrating compliance for 3 years following completion of the renovation. One year is too short; 5 years is the renovator refresher interval; and the sale of the home is not the measure.

- 7. Cabinet Installation
How does the federal finish-carpentry guide specification say countertops should be provided?
- a.In the longest practical lengths
- b.In stock lengths, if joints are caulked
- c.In short sections for easier handling
- d.In lengths joined at each cabinet
Answer: a
Explanation: The guide specification calls for counter sections in the longest lengths practicable with a minimum number of joints, joined with concealed pull-up bolts and water-resistant glue where joints are needed. Short sections and joints at every cabinet add joints; caulk does not replace the joint method.

What does the federal finish-carpentry guide specification say about face nails in finish work?
- a.Leave them flush and paint over them
- b.Avoid them on painted trim
- c.Clinch them on the back of the trim
- d.Set them for putty stopping
Answer: d
Explanation: The guide specification calls for finish nails, blind nailing where practicable, and face nails set for putty stopping. Leaving nails flush skips the setting and puttying the specification calls for; clinching bends over nails driven through stock and is not a finish method; and the specification allows set face nails rather than avoiding them.

Under the federal glazing standard, what makes a safety-glazing label "permanent"?
- a.It is a paper sticker on the glass
- b.It is printed on the window's packing carton
- c.It is listed on the installer's invoice
- d.It stays legible; removal destroys it
Answer: d
Explanation: The federal standard defines a permanent label as one that remains legible and visible after installation and would be destroyed in attempts to remove it, such as sandblasted or acid-etched marks. A carton, a removable paper sticker, or an invoice entry does not meet that definition.

What is the action level for respirable crystalline silica under Section 5204?
- a.10 micrograms per cubic meter
- b.100 micrograms per cubic meter
- c.25 micrograms per cubic meter
- d.50 micrograms per cubic meter
Answer: c
Explanation: Section 5204 sets the action level at 25 micrograms per cubic meter and the permissible exposure limit at 50, both as 8-hour TWAs. Ten micrograms is the lead PEL, and 100 micrograms is not a silica figure in the rule.
