Question: 1 / 400

Which substance is most likely to give off hazardous vapors?

Water

Plywood

Glue

The substance most likely to give off hazardous vapors is glue. Many types of glue, particularly those that are solvent-based, contain volatile organic compounds (VOCs) which can evaporate into the air, potentially leading to breathing difficulties or other health issues when inhaled. These vapors can be especially harmful in enclosed or poorly ventilated spaces.

In contrast, while cement can produce dust and may cause irritation, it does not typically emit harmful vapors like some glues do. Water is generally safe and does not emit any vapors under normal circumstances. Plywood, while it may off-gas certain chemicals if treated, is less likely to be associated with hazardous vapors than glues used in conjunction with construction projects. Thus, glue stands out as the primary source of potentially hazardous vapors among the listed substances.
