Which of the following is a consequence of improper ventilation during painting?

Improper ventilation during painting can lead to the accumulation of hazardous fumes and toxic substances in the work area. When there is inadequate airflow, volatile organic compounds (VOCs) and other harmful vapors from the paint can concentrate, posing serious health risks to technicians. Prolonged exposure to these fumes can lead to respiratory issues, headaches, nausea, and other health problems. Additionally, a lack of proper ventilation can also result in a poor working environment, making it essential for safety and health standards to maintain adequate airflow during the painting process.

The other options do not reflect the consequences of improper ventilation. Increased safety for the technician relates to having sufficient airflow to mitigate health risks, while improved paint adhesion and faster drying times are benefits typically associated with optimal conditions rather than the consequences of poor ventilation.
