Which material is specified as needing proper ventilation when applied?

• A. Contact cement
• B. Table salt
• C. Water
• D. Glue stick

Answer: (A)

The most important idea here is that some adhesives give off strong fumes that can irritate you or be hazardous if you breathe them in, so they need good ventilation during use. Contact cement is a solvent-based adhesive that releases volatile organic compounds (VOCs) as it evaporates. Because of those fumes, you should work in a well-ventilated area (or use local exhaust) and minimize exposure, especially when applying it to both surfaces and pressing them together.

The other items listed don’t pose the same ventilation concern in typical cabinetmaking use. Table salt is an inert solid, water is non-volatile, and glue sticks are generally low in fumes compared with solvent-based adhesives. So ventilation is not as critical for them in the way it is for contact cement.
