What is a common combustible material used in cabinetmaking?

• A. Paint thinner
• B. Wood glue
• C. Contact cement
• D. Plywood

Answer: (C)

In cabinetmaking, many adhesives and solvents used in the shop are flammable, so recognizing which material is a common combustible hazard is about understanding the solvent-based products you work with. Contact cement is a solvent-based adhesive that you’ll often use to bond laminates and veneers. Those solvents are highly flammable, so the vapors can ignite if there’s a spark or open flame and the material can burn if exposed to heat. That combination of wide use in cabinetry and the presence of flammable solvents makes contact cement a typical combustible material in the cabinetmaking process.

Paint thinner is indeed a flammable solvent, but its primary role is thinning finishes and cleaning brushes rather than serving as a primary bonding agent in cabinetry. Wood glue isn’t considered highly flammable once cured, and plywood is a wood product—flammability is a concern with all wood, but it isn’t the adhesive material contributing the common shop hazard highlighted in cabinetmaking. So the solvent-based adhesive used to bind laminates and veneers fits the scenario described. Remember to use it in a well-ventilated area, keep ignition sources away, and follow all storage and handling guidelines.
