Which option best supports maintaining good air quality after cleaning up a chemical spill?

• A. Leave doors closed to contain fumes.
• B. Ventilate the area to disperse fumes.
• C. Continue to ventilate only if someone reports dizziness.
• D. Ignore any odors and proceed.

Answer: (B)

Ventilating the area to disperse fumes is essential because many chemical spills release vapors that can irritate or harm the respiratory system even at low levels. By opening windows or doors or using fans, you dilute and remove these fumes, reducing inhalation risk for anyone cleaning up and for others who might enter. Leaving doors closed traps the fumes and can increase exposure. Waiting to ventilate only when dizziness occurs is reactive and can allow harmful concentrations to build up first. Ignoring odors is unsafe because smells often indicate the presence of hazardous vapors. Proactive ventilation helps maintain safer air quality during cleanup.
