Question 4

When working with chemicals, they might splash, and glassware could break, sending shards or chemical droplets toward the eyes. Goggles protect the eyes from chemical burns, irritation, or injury from broken glass.

Loose clothing or long hair can catch fire from the Bunsen burner's flame. Tying back long hair and wearing fitted, non - flammable clothing (or rolling up sleeves) prevents ignition and burns.

Shorts or skirts leave the legs exposed. If chemicals spill or glassware breaks, the legs are unprotected, leading to chemical burns, cuts from glass, or other injuries. Long pants provide a protective layer.

Answer:

To protect the eyes from chemical splashes, fumes (if any), and injury from broken glassware. Chemicals can cause burns or irritation, and broken glass shards can injure the eyes; goggles act as a barrier.
