Explanation:

Identify the exercise goal

The exercise requires matching WHMIS hazard class labels with their corresponding visual symbols (pictograms) shown at the bottom of the screen.

Analyze the hazard classes

We have nine distinct hazard classes arranged in a \(3 \times 3\) grid:

1. Gas Cylinder: Represents gases under pressure.
2. Flame: Represents fire hazards (flammable materials).
3. Corrosion: Represents corrosive damage to metals, skin, or eyes.
4. Flame Over Circle: Represents oxidizing hazards.
5. Skull And Crossbones: Represents acute toxicity (severe or fatal).
6. Exclamation Mark: Represents less severe health hazards or ozone layer hazards.
7. Biohazardous Infectious Materials: Represents organisms or toxins that can cause disease.
8. Exploding Bomb: Represents self-reactive or explosive hazards.
9. Health Hazard: Represents chronic health hazards (carcinogenicity, respiratory sensitization, etc.).

Match symbols to classes

Looking at the symbols at the bottom from left to right:

• First symbol (cylinder shape): Gas Cylinder.
• Second symbol (pouring liquid onto a hand and surface): Corrosion.
• Third symbol (exclamation mark): Exclamation Mark.
• Fourth symbol (exploding object): Exploding Bomb.
• Fifth symbol (fire/flame): Flame.
• Sixth symbol (silhouette of a person with a starburst on the chest): Health Hazard.
• Seventh symbol (flame over a circle): Flame Over Circle.
• Eighth symbol (skull and crossbones): Skull And Crossbones.
• Ninth symbol (three circles merged in a black circle, WHMIS biohazard symbol): Biohazardous Infectious Materials.

Structure the final mapping

We will present a clear, structured mapping of each hazard class to its corresponding visual description from the bottom row to help the student complete the drag-and-drop exercise.

Answer:

To complete the drag-and-drop exercise, match each hazard class name with the corresponding symbol from the bottom row:

• Gas Cylinder
• Symbol: The cylinder icon (1st from the left).
• Flame
• Symbol: The simple flame icon (5th from the left).
• Corrosion
• Symbol: The icon showing liquids pouring onto a hand and a surface (2nd from the left).
• Flame Over Circle
• Symbol: The flame on top of a circular ring icon (7th from the left).
• Skull And Crossbones
• Symbol: The skull and crossbones icon (8th from the left).
• Exclamation Mark
• Symbol: The exclamation mark icon (3rd from the left).
• Biohazardous Infectious Materials
• Symbol: The black circular symbol containing three overlapping crescent shapes (9th from the left).
• Exploding Bomb
• Symbol: The shattering/exploding object icon (4th from the left).
• Health Hazard
• Symbol: The silhouette of a person with a starburst on their chest (6th from the left).
