Which piece of safety equipment is MOST important to wear when working with chemicals that could splash or create fumes?

Gloves
Lab coat
Goggles
Closed-toe shoes

Correct Answer

A. Goggles

Goggles are the most crucial safety item when dealing with potentially hazardous chemicals. They provide a protective barrier for the eyes, preventing splashes and harmful fumes from causing irritation, burns, or even blindness. While other options offer protection, goggles directly safeguard the vulnerable eyes, making them paramount in a laboratory setting.

Make sure equipment is clean

Before you use it
After you use it
Both a and b
When you have time

Correct Answer

A. Both a and b

Explanation

The correct answer is "Both a and b" because it is important to clean the equipment both before and after using it. Cleaning the equipment before use ensures that it is free from any dirt or contaminants that could affect its performance or cause harm. Cleaning the equipment after use helps to maintain its longevity and prevent the buildup of any residue or bacteria. By doing both, you can ensure that the equipment is in optimal condition and safe to use.

If you are not sure what to do during an lab or activity

Ask the teacher
Ask a lab partner
Sit and wait quietly
Guess

Correct Answer

A. Ask the teacher

Explanation

During a lab or activity, it is important to seek guidance and clarification if unsure about what to do. Asking the teacher for assistance is the best course of action as they are responsible for providing instructions and can provide guidance tailored to the specific task. Asking a lab partner may be helpful, but they may also be unsure or provide incorrect information. Sitting and waiting quietly is a passive approach that may waste time and hinder progress. Guessing is not advisable as it can lead to mistakes or accidents. Therefore, asking the teacher is the most appropriate and reliable option.

Goggles are not needed if you wear glasses.

True
False

Correct Answer

A. False

Explanation

Wearing glasses does not eliminate the need for goggles. Goggles provide additional protection for the eyes, especially in certain situations such as swimming, working with chemicals, or participating in sports. Glasses may not provide adequate coverage or protection from potential hazards. Therefore, it is incorrect to say that goggles are not needed if you wear glasses.
