Question
An experiment requires students to wear a lab apron, thin latex gloves, and goggles. This equipment will best protect the students from — A burns while handling a beaker of boiling water B burns while mixing chemicals in a test tube C cuts while working with a sharp scalpel D shocks while working with live, low-voltage electrical wires

The equipment described—lab apron, thin latex gloves, and goggles—provides protection primarily against spills and splashes of liquids, including those that could cause burns or irritation.
Let's analyze each option:
A. **Burns while handling a beaker of boiling water** - The lab apron and goggles offer some protection from splashes, but gloves may not provide sufficient protection from heat.
B. **Burns while mixing chemicals in a test tube** - Similar to option A, the apron and goggles are protective, but gloves do not protect against chemical burns effectively if they are thin latex.
C. **Cuts while working with a sharp scalpel** - Though the gloves might offer some protection, they are not designed to prevent cuts. The apron and goggles do not protect against cuts effectively either.
D. **Shocks while working with live, low-voltage electrical wires** - The equipment specified does not provide adequate protection against electrical shocks.
Given these considerations, the best answer would be:
**B. burns while mixing chemicals in a test tube.**
While the latex gloves alone may not be ideal for handling certain chemicals, the combination of PPE does offer some basic protection against chemical spills that could cause burns.
