Accepted Answer

### 3a
# Brief Explanations:
To determine inappropriate lab attire, we analyze the left - hand student's appearance. Long, loose hair is a hazard as it can catch fire or interfere with equipment. Open - toed shoes (like sandals) offer no protection against spills or broken glass. Shorts expose the legs, leaving them vulnerable to chemical splashes or burns.
# Answer:
- Long, loose hair.
- Open - toed shoes (sandals).
- Shorts.

### 3b
# Brief Explanations:
For the right - hand student, we look for attire that follows lab safety rules. Tied - back hair keeps it out of the way and reduces fire risk. Closed - toed shoes protect the feet. A lab apron (or appropriate work dress) shields the body from chemical splashes and other hazards.
# Answer:
- Hair tied back.
- Closed - toed shoes.
- Lab apron (or appropriate work dress).

### 4
# Brief Explanations:
When working with chemicals, there's a risk of splashes. Glassware can break, sending shards or chemical - laden fragments towards the eyes. Goggles act as a physical barrier, preventing chemicals from entering the eyes (which can cause severe damage) and protecting against flying glass particles that could cause eye injuries.
# Answer:
To protect the eyes from chemical splashes (which can cause severe damage like burns or blindness) and from flying glass fragments (in case glassware breaks), as these substances can easily enter the eyes and cause injury.

### 5
# Brief Explanations:
Clothing: Loose clothing can catch fire from the Bunsen burner's flame. So, one should wear fitted or lab - appropriate clothing. Hair: Long hair is a fire hazard. It should be tied back to keep it away from the flame, preventing it from catching fire.
# Answer:
For clothing: Avoid loose - fitting clothes (they can catch fire from the Bunsen burner flame). For hair: Tie long hair back (to keep it away from the flame and prevent it from catching fire).

### 6
# Brief Explanations:
Shorts and skirts expose the legs. Chemicals can splash onto the legs, causing burns or other damage. Also, if glassware breaks, there's no fabric to protect the legs from cuts. Long pants (or appropriate lab attire) provide a layer of protection against these hazards.
# Answer:
Shorts and skirts expose the legs. Chemical splashes can burn the legs, and broken glassware can cut the legs. Long pants (or proper lab attire) protect the legs from such hazards.

### 7
# Brief Explanations:
Closed - toed shoes are necessary. They protect the feet from chemical spills (which can cause burns) and from broken glassware (which can cause cuts). Open - toed shoes like sandals or flip - flops leave the feet exposed to these risks.
# Answer:
Closed - toed shoes. They protect the feet from chemical spills (which can cause burns) and broken glassware (which can cause cuts).

### 8
# Brief Explanations:
The student on the right is dressed appropriately. Their tied - back hair reduces fire risk, closed - toed shoes protect the feet, and the lab apron (or appropriate dress) shields the body. The left - hand student's attire (loose hair, open - toed shoes, shorts) offers little protection. So, the right - hand student's clothing provides protection against fire, chemical splashes, and broken glass - related injuries.
# Answer:
The student on the right. Their hair is tied back (reducing fire risk), they wear closed - toed shoes (protecting feet), and their attire (like the lab apron - style dress) shields the body from chemical splashes and potential cuts from broken glass. The left - hand student's loose hair, open - toed shoes, and shorts offer little protection.
