Wyoming MPJE (Pharmacy Jurisprudence) Practice Exam

What is the proper storage environment for a hazardous substance?

1. Positive pressure with sufficient exhaust with 10 air changes per hour

2. Positive pressure with sufficient exhaust with 12 air changes per hour

3. Negative pressure with sufficient exhaust with 12 air changes per hour

4. Negative pressure with sufficient exhaust with 10 air changes per hour

The correct answer is: Positive pressure with sufficient exhaust with 10 air changes per hour

The correct answer is A. Positive pressure with sufficient exhaust with 10 air changes per hour is the proper storage environment for a hazardous substance. This setup helps to prevent the spread of the hazardous substance by ensuring that there is continuous airflow out of the storage area. Positive pressure helps to keep the hazardous substance contained within the storage space, while the exhaust system helps to remove any potentially dangerous fumes or particles. Additionally, 10 air changes per hour is a sufficient rate to maintain a safe environment for storing hazardous substances. Options B, C, and D are incorrect because they do not describe the appropriate storage environment for a hazardous substance.
