Explanation:

To solve these lab - safety - related fill - in - the - blank questions, we rely on common laboratory safety knowledge:

Question 4

In a laboratory, activities like running, playing, or eating/drinking are not allowed as they can cause accidents or contaminate samples. A common answer here is "horseplay" (or "eating/drinking", "running" etc.). Let's take "horseplay" as an example.

Step 1: Recall lab safety rules

Lab safety rules prohibit any form of rough or careless behavior (horseplay) as it can lead to spills, breakages, or injuries.

Step 2: Fill in the blank

So, the blank can be filled with "horseplay".

Question 5

To ensure safety in the lab, one should follow all the given directions. The verb that fits here is "Follow".

Step 1: Understand the context

The sentence is about adhering to the instructions given for lab work.

Step 2: Choose the correct verb

The word "Follow" makes sense here as we follow directions to stay safe in the lab. So, the blank is filled with "Follow".

Question 6

In a lab, it's essential to learn the safety procedures to prevent accidents. So, the blank should be filled with "safety".

Step 1: Relate to lab safety

Lab work requires knowledge of safety procedures to protect oneself and others.

Step 2: Fill the blank

Thus, we put "safety" in the blank.

Question 7

In a lab, one must know where the first - aid kit (or other safety equipment like fire extinguisher, eye - wash station) is stored. Let's take "the first - aid kit" as an example.

Step 1: Recall lab safety requirements

Knowing the location of safety equipment is a key part of lab safety.

Step 2: Fill in the blank

So, the blank can be filled with "the first - aid kit".

Question 8

To keep the aisles clear in the lab, we need to push stools (or chairs, equipment) out of the way. Let's take "stools" as an example.

Step 1: Consider lab organization

To maintain a safe and organized lab space, movable objects like stools should be pushed aside.

Step 2: Fill the blank

So, the blank is filled with "stools".

Answer:

s:

1. horseplay (or other appropriate answers like eating/drinking, running)
2. Follow
3. safety
4. the first - aid kit (or other safety equipment)
5. stools (or other appropriate objects)
