Step-by-step solution for: Laboratory Safety Rules Worksheet - EduMonitor
Let's go through each question on the "Laboratory Safety Rules" worksheet and solve them step by step with explanations.
---
Options:
(a) Ask questions
(b) Use equipment
(c) Conduct experiments
(d) Wear safety goggles
✔ Correct Answer: (c) Conduct experiments
Explanation:
While asking questions, using equipment under supervision, and wearing safety goggles are encouraged or required, conducting experiments without permission is dangerous and against lab rules. You must have teacher approval before starting any experiment to ensure safety procedures are followed.
---
Options:
(a) Lab coat or long sleeves
(b) Closed-toe shoes
(c) Shorts or exposed skin
(d) Safety goggles
✔ Correct Answer: (c) Shorts or exposed skin
Explanation:
In a lab, you need to protect your skin from spills, chemicals, and heat. Shorts or exposed skin leave you vulnerable to accidents. Proper lab attire includes long pants, closed-toe shoes, lab coats, and safety goggles.
---
Options:
(a) To impress your teacher
(b) To show you're finished
(c) To remove harmful chemicals
(d) To get lunch faster
✔ Correct Answer: (c) To remove harmful chemicals
Explanation:
Chemicals used in labs can be toxic or irritating. Even if they don’t feel harmful, they might remain on your hands and could enter your body through touching your face or food. Washing hands removes contaminants and prevents accidental exposure.
---
Options:
(a) Put it in a sharps container
(b) Pick it up with your hands
(c) Inform your teacher
(d) Throw it in the trash
✔ Correct Answer: (b) Pick it up with your hands
Explanation:
Broken glass can cut you. Never pick it up with bare hands. Instead, use a broom and dustpan or a special tool, and place it in a sharps container. Always inform your teacher about broken glass so proper cleanup can happen safely.
---
Options:
(a) Continue your experiment
(b) Tell your friend it's probably fine
(c) Alert your teacher immediately
(d) Open a window for ventilation
✔ Correct Answer: (c) Alert your teacher immediately
Explanation:
The image shows a fire extinguisher or emergency shower, but based on the context of “douse flames” and the diagram showing red arrows upward (suggesting fire), the correct action is alerting your teacher immediately. Teachers know how to handle emergencies safely. You should not try to handle fires alone unless trained.
> Note: While fire extinguishers are used to douse flames, the question asks what you should do — and the safest action is to alert the teacher first.
---
Options:
(a) Decoration
(b) Identify potential hazards
(c) Mark exits
(d) Show where equipment is stored
✔ Correct Answer: (b) Identify potential hazards
Explanation:
Safety symbols (like the yellow triangle with an exclamation mark shown) warn you about dangers such as toxic substances, flammable materials, or corrosive chemicals. They help everyone recognize risks quickly and take precautions.
