Review of HHPs and WHMIS symbols on a lab safety worksheet.

Let's solve this Lab Safety Worksheet step by step. The task is to identify whether each of the 20 symbols shown is a HHPS (Hazardous Household Products Symbol) or a WHMIS (Workplace Hazardous Materials Information System) symbol, and then write the name of each symbol.

---

🔍 Background Knowledge:

- HHPS Symbols: Used for household hazardous products (e.g., cleaning supplies). These are typically simpler and more general.
- WHMIS Symbols: Used in workplaces in Canada for hazardous materials. WHMIS uses diamond-shaped labels with specific pictograms (often black on white background) and includes:
- Flammable
- Corrosive
- Toxic/Health Hazard
- Oxidizing
- Explosive
- Biohazard
- Environmental Hazard
- etc.

> Key Difference: WHMIS symbols are usually diamond-shaped, while HHPS symbols often use circles, triangles, or octagons. However, some overlap exists.

We'll analyze each symbol one by one.

✔ Let’s go through each symbol row by row:

---

#### Row 1

1. Symbol: Circle with a broken test tube
- Type: HHPS
- Name: Breakable Glass / Fragile
- *This is not a standard WHMIS hazard; it's common in household labs.*

2. Symbol: Triangle with skull & crossbones
- Type: WHMIS
- Name: Toxic / Poison
- *Classic WHMIS symbol for toxicity.*

3. Symbol: Octagon with hand being burned
- Type: WHMIS
- Name: Corrosive
- *Common WHMIS symbol for corrosive substances.*

4. Symbol: Circle with plant dying
- Type: HHPS
- Name: Environmental Hazard
- *Often used on household chemicals harmful to plants/water.*

---

#### Row 2

5. Symbol: Triangle with hand being burned
- Type: WHMIS
- Name: Corrosive
- *Same as above but triangle shape — still WHMIS.*

6. Symbol: Octagon with exploding hand
- Type: WHMIS
- Name: Explosive
- *Indicates explosive material.*

7. Symbol: Circle with "T" and exclamation mark
- Type: WHMIS
- Name: Irritant / Health Hazard
- *“T” stands for “Toxic” or “Irritating.”*

8. Symbol: Triangle with exploding object
- Type: WHMIS
- Name: Explosive
- *Another variation of explosive hazard.*

---

#### Row 3

9. Symbol: Octagon with flame
- Type: WHMIS
- Name: Flammable
- *Standard flammable symbol.*

10. Symbol: Circle with flame over circle
- Type: WHMIS
- Name: Oxidizing Agent
- *Flame over circle = oxidizer.*

11. Symbol: Diamond with explosion
- Type: WHMIS
- Name: Explosive
- *Diamond shape = WHMIS.*

12. Symbol: Octagon with skull & crossbones
- Type: WHMIS
- Name: Toxic / Poison
- *Same as earlier but octagonal.*

---

#### Row 4

13. Symbol: Circle with biohazard symbol
- Type: WHMIS
- Name: Biohazard
- *Used for biological hazards (e.g., viruses, bacteria).*

14. Symbol: Diamond with flame
- Type: WHMIS
- Name: Flammable
- *Diamond-shaped → WHMIS.*

15. Symbol: Triangle with flame
- Type: WHMIS
- Name: Flammable
- *Triangle version of flammable.*

16. Symbol: Circle with flame
- Type: WHMIS
- Name: Flammable
- *Simple flame = flammable.*

---

#### Row 5

17. Symbol: Diamond with skull & crossbones
- Type: WHMIS
- Name: Toxic / Poison
- *Standard WHMIS toxic symbol.*

18. Symbol: Circle with "R" and radiation lines
- Type: WHMIS
- Name: Radioactive
- *“R” = Radioactive hazard.*

19. Symbol: Circle with skull & crossbones
- Type: WHMIS
- Name: Toxic / Poison
- *Another version of poison symbol.*

20. Symbol: Diamond with hand being burned
- Type: WHMIS
- Name: Corrosive
- *Diamond shape → WHMIS.*

| 13 | WHMIS | Biohazard |
| 14 | WHMIS | Flammable |
| 15 | WHMIS | Flammable |
| 16 | WHMIS | Flammable |
| 17 | WHMIS | Toxic / Poison |
| 18 | WHMIS | Radioactive |

📌 Summary Notes:

- HHPS symbols are mostly non-standardized and used for household items. Only one clear HHPS symbol here: #1 (fragile glass) and #4 (environmental hazard).
- Most of these symbols are WHMIS, especially those with diamond shapes or standard hazard icons like skull & crossbones, flames, corrosion, etc.
- The circle with “T” and exclamation mark is a WHMIS health hazard symbol.
- The radiation symbol ("R") is also part of WHMIS.

✔ Final Answer: You should fill in the worksheet using the table above. All symbols except #1 and #4 are WHMIS. The rest are WHMIS symbols.
