The first steps of this lesson

Step 1: Why a Cabinetmaker Checks the Paperwork

Cabinet boxes, doors and shelves are made from composite wood, and they are glued and finished on site or in the shop. The 2025 California Green Building Standards Code (CALGreen) sets mandatory limits on what goes into the building. For residential work they are in Chapter 4 (Section 4.504); for nonresidential work they are in Chapter 5 (Section 5.504.4). The enforcing agency can ask for proof, so the cabinetmaker keeps the product data.

Step 2: Formaldehyde Limits for Panel Stock

CALGreen 4.504.5 (nonresidential: 5.504.4.5) says hardwood plywood, particleboard and medium density fiberboard used on the interior or exterior of the building shall meet the formaldehyde limits of the ARB Air Toxics Control Measure for Composite Wood (17 CCR 93120 et seq.), shown in Table 4.504.5 (nonresidential Table 5.504.4.5). Maximum emissions in parts per million: hardwood plywood veneer core 0.05, hardwood plywood composite core 0.05, particleboard 0.09, medium density fiberboard 0.11, thin medium density fiberboard 0.13. Thin MDF has a maximum thickness of 5/16 inch (8 mm).

The remaining 3 steps, the worked example and the quiz are in the course. This is a preview. The full lesson, with the step-by-step explanations, a worked example and a quick-check quiz, is inside the classroom.
