    What is the first thing you should do if a chemical spills on your skin?

    • Wash with water immediately

    • Take a photo

    • Call your friend

    • Ignore it

    Correct Answer
    A. Wash with water immediately
    Explanation
    Immediate washing with water upon chemical contact with the skin is critical to mitigate chemical burns or skin damage. Water dilutes and washes away the chemicals, reducing absorption into the skin and lowering the risk of a severe reaction. This action must be prompt to decrease the exposure time and potential harm. Delaying this step can result in deeper penetration of the chemical, leading to more significant injuries. Thus, quick and thorough rinsing is a vital first response to chemical spills on the skin.

    Which item should you wear to protect your eyes in the lab?

    • Sunglasses

    • Prescription glasses

    • Safety goggles

    • No protection needed

    Correct Answer
    A. Safety goggles
    Explanation
    Safety goggles are specifically designed to protect the eyes from chemical splashes, flying debris, or broken glass that might occur during lab experiments. Unlike regular glasses, safety goggles form a protective seal around the eyes, preventing harmful substances from reaching the eye area. This is crucial in a lab setting where exposure to chemicals and reactions can cause severe eye injuries or blindness. Therefore, wearing safety goggles is a standard safety protocol that serves as a primary defense against potential eye hazards.

    What must you do if you don't understand part of a lab procedure?

    • Guess and check with a classmate

    • Change the procedure to something familiar

    • Ask the instructor for clarification

    • Skip the unclear parts and proceed

    Correct Answer
    A. Ask the instructor for clarification
    Explanation
    Asking the instructor for clarification on unclear lab procedures is fundamental for safety and accuracy. Misunderstanding a step can lead to incorrect execution of the experiment, which might not only yield invalid results but also pose serious safety risks. Direct communication with the instructor ensures that you receive accurate information and guidance, reducing the likelihood of mistakes. This proactive approach promotes a thorough understanding and correct application of the lab procedures.

    Why is it important to tie back long hair during lab experiments?

    • It looks neater.

    • It prevents chemical contamination.

    • It prevents hair from catching fire or being caught in equipment.

    • To keep cool

    Correct Answer
    A. It prevents hair from catching fire or being caught in equipment.
    Explanation
    Tying back long hair during lab experiments is crucial for safety. Loose hair can easily catch fire when exposed to flames or hot surfaces commonly found in labs. It can also become entangled in moving equipment, which may lead to severe injuries or disrupt the experiment. By securing long hair, the risk of these accidents is significantly minimized. This practice not only promotes safety but also maintains the integrity of the experimental procedures by avoiding unwanted contamination or interference.

    Rate this question:

  • 6. 

    When is it acceptable to eat or drink in the lab?

    • When you are not doing any experiment

    • When you are using non-toxic materials

    • Never

    • Only during breaks

    Correct Answer
    A. Never
    Explanation
    Eating or drinking in the lab is prohibited at all times to prevent chemical contamination. Consumables can absorb toxic substances from the air, equipment, or contaminated surfaces, leading to ingestion of harmful chemicals. Even non-toxic materials can pose risks if they come into contact with food or drinks. The lab environment must be kept strictly for scientific work to ensure that all safety standards are met and that there is no cross-contamination between edible items and lab chemicals.

    Rate this question:

  • 7. 

    What type of footwear is best for lab work?

    • Open-toe sandals

    • High heels

    • Sneakers

    • None; barefoot is fine

    Correct Answer
    A. Sneakers
    Explanation
    Sneakers are the recommended footwear for lab work due to several safety features. They cover the entire foot, protecting against spills and sharp objects like broken glass. The material and design of sneakers also provide stability and slip resistance, which is vital in environments where spills can make floors hazardous. Open-toe sandals and high heels expose the feet to potential chemical spills and injuries, and do not offer the necessary grip, making sneakers the safest and most practical choice.

    Rate this question:

  • 8. 

    If you break a glass during an experiment, what should you do?

    • Pick up the pieces with your hands

    • Tell the instructor

    • Sweep them under the rug

    • Continue with the experiment

    Correct Answer
    A. Tell the instructor
    Explanation
    Informing the instructor immediately after breaking glass is essential for safe cleanup and to prevent injuries. Instructors are trained to handle such incidents safely and can guide the proper disposal of broken glass, often using specific tools like a brush and dustpan to avoid direct hand contact. Reporting also allows for a quick response to replace broken equipment if necessary and ensure that no part of the experiment is compromised. This action avoids potential harm to other students and maintains the safety and order within the lab environment.

    Rate this question:

  • 9. 

    Where should chemicals be disposed of?

    • In the nearest sink

    • In the designated disposal containers

    • On the floor

    • Outside the lab building

    Correct Answer
    A. In the designated disposal containers
    Explanation
    Designated disposal containers are crucial for safely handling chemical waste. These containers are typically designed to handle specific types of chemicals, preventing reactions that could occur if incompatible substances are mixed. Disposing chemicals in sinks or on the floor can lead to environmental damage, personal injury, and can compromise plumbing systems. Using the correct disposal containers ensures that harmful chemicals are contained and treated appropriately, maintaining safety and compliance with environmental regulations.

    Rate this question:

  • 10. 

    How should you smell a chemical if instructed to note its odor?

    • Directly inhale from the container

    • Use your hand to waft the odor toward your nose

    • Sniff quickly and directly

    • Ask someone else to do it

    Correct Answer
    A. Use your hand to waft the odor toward your nose
    Explanation
    Wafting is a technique used to safely smell chemicals. It involves gently waving your hand over the container to direct a small amount of vapor toward your nose. This method minimizes exposure to potentially harmful fumes, unlike direct inhalation, which can lead to inhaling a concentrated amount of chemical vapors, possibly causing respiratory irritation or damage. Wafting provides a controlled way to detect odors without risking health, making it a standard practice for safely checking chemical properties.
