Explanation:

Question 2

Broken glass has safety risks (sharp edges) and needs proper disposal. Regular trash, desk drawer, or sink are unsafe/incorrect. Designated glass containers are for safe disposal of broken glass.

Electrical equipment and water (wet hands) are dangerous (electric shock). Washing or wetting hands is unsafe. Gloves aren't necessary here; drying hands (to remove moisture) is key before using electrical equipment.

Bunsen burners produce flames. Long, loose hair can catch fire. Dyeing/cutting hair is irrelevant. Tying hair back prevents fire hazards; leaving it loose is dangerous.

Answer:

c) Designated glass container
