Question

1. why should one avoid wearing shorts or skirts while working with chemicals and with glassware?
2. if an accident occurred in the laboratory, which of the two students in the model would have protection provided by their clothing? why?

Explanation:

Question 5

Wearing shorts or skirts in a lab with chemicals/glassware exposes legs. Chemical spills or broken glass can cause burns, cuts, or chemical absorption. Long pants protect legs from such hazards.

The student with proper lab clothing (e.g., lab coat, long pants, closed - toe shoes) has protection. Lab coats shield the body from spills, long pants protect legs, and closed - toe shoes protect feet. The other (in inappropriate clothing like shorts) has less protection as exposed skin is at risk from spills, broken glass, etc.

Answer:

One should avoid wearing shorts or skirts because they expose the legs, leaving them vulnerable to chemical spills (which can cause burns or chemical absorption) and injuries from broken glassware (like cuts). Long pants provide better protection against these laboratory hazards.

Question 6

(Note: Since the "two students in the model" isn't described, we assume a common lab clothing scenario, e.g., one in lab coat/long pants, one in shorts/skirt. Here's a general explanation.)
