🔍 Understanding the Symbols

We are asked to identify whether each symbol is from:
- HHPS (Hazardous Household Products Symbol) — typically used in consumer products.
- WHMIS (Workplace Hazardous Materials Information System) — used in workplaces, especially in Canada.

The key difference:
- WHMIS uses standardized symbols with specific shapes and meanings (e.g., diamond-shaped for health hazards).
- HHPS uses simpler, more general symbols often seen on household cleaning or chemical products.

But note: Many of these symbols are shared between systems. However, the shapes and designs help distinguish them.

Let’s go through each symbol row by row.

## ✔ Final Answer Table

| Symbol | HHPS or WHMIS? | Name |
|-------|----------------|------|
| 1 | HHPS | Corrosive |
| 2 | WHMIS | Toxic |
| 3 | WHMIS | Corrosive |
| 4 | HHPS | Environmental Hazard |
| 5 | WHMIS | Corrosive |
| 6 | WHMIS | Explosive |
| 7 | HHPS | Irritant / Health Hazard |
| 8 | WHMIS | Reactive |
| 9 | WHMIS | Flammable |
| 10 | HHPS | Oxidizer |
| 11 | WHMIS | Explosive |
| 12 | WHMIS | Toxic |
| 13 | HHPS | Biohazard |
| 14 | WHMIS | Flammable |
| 15 | WHMIS | Flammable |
| 16 | HHPS | Flammable |
| 17 | WHMIS | Toxic |
| 18 | HHPS | Radioactive |
| 19 | HHPS | Toxic |
| 20 | WHMIS | Corrosive |

## 📌 Summary Notes:

- WHMIS uses diamond-shaped symbols (like GHS), while HHPS often uses circles or triangles.
- Some symbols (like flammable, toxic, corrosive) appear in both systems but with different shapes.
- The circle is typical for HHPS, and diamond/octagon/triangle are common in WHMIS.
- Always look at shape first, then icon.
