Why may a fume hood be necessary while using phenol?

Answer and explanation

Correct answer: To protect against exposure to hazardous fumes

Phenol is a toxic, corrosive chemical, and its vapours can be harmful to health. A fume hood removes vapours from the work area and reduces the risk of inhalation exposure; therefore, option C is correct. PPE protects the skin and eyes but does not replace a fume hood. A fume hood is not used to stain DNA or to speed up PCR. Exam tip: associate volatile or toxic chemicals with use of a fume hood and appropriate PPE.
