Answer:

The correct option is False

Explanation:

During preparation of some reagents, that involves the use of harmful constituents like concentrated acids, students (high school students) may be prevented from entering the chemical preparation/storage area until the preparation is completed and the area is area deemed safe for students. Students may also be prevented from entering the preparation/storage area if a student does not wear the appropriate protective wear during preparation of reagents or during "trial-runs" of reagents. For example, diethyl ether has a choking smell and if a student doesn't wear a face mask, the student may be seriously affected (health-wise) by this choking substance which is hazardous when inhaled in high concentration.
