Question

question 1. select all statements that correctly explain why safety glasses or goggles must be worn at all times in the laboratory, even when an individual is not personally conducting an experiment. there may be more than one correct answer.

□ chemical spills, splashes, or reactions can occur unexpectedly, even from nearby experiments.

□ flying debris or broken glass from accidents can cause eye injuries.

□ wearing goggles or glasses ensures compliance with laboratory safety regulations.

□ eye protection eliminates the need to follow other safety precautions.

□ other individuals’ experiments may pose hazards to everyone in the laboratory.

Explanation:

• For the first option: Chemical spills/splashes/reactions from nearby experiments can unexpectedly harm eyes, so eye protection is needed.
• Second option: Accidents in the lab can produce flying debris or broken glass, which can injure eyes, so goggles/glasses protect against that.
• Third option: Wearing eye protection is a part of laboratory safety regulations, so this is a valid reason for compliance.
• Fourth option: Eye protection does not eliminate the need for other safety precautions (e.g., proper handling of chemicals, wearing gloves), so this is incorrect.
• Fifth option: Other people's experiments in the lab can create hazards (like chemical splashes, explosions) that affect everyone, so eye protection is necessary.

Answer:

• Chemical spills, splashes, or reactions can occur unexpectedly, even from nearby experiments.
• Flying debris or broken glass from accidents can cause eye injuries.
• Wearing goggles or glasses ensures compliance with laboratory safety regulations.
• Other individuals’ experiments may pose hazards to everyone in the laboratory.
