Hazard symbol matching test class 6 adr irish exam trick online game
The Class 6 trick is that it holds two different hazards with different symbols. Division 6.1 is poison (toxic), shown with the skull and crossbones. Division 6.2 is infectious substances, shown with the biohazard symbol (three crescents). Matching a Class 6 question means reading which symbol it is, since the class number alone does not tell you.
Class 6 is two different dangers
The catch with Class 6 is that it is not one hazard. Division 6.1 is poison: toxic solids and liquids, marked with the skull and crossbones. Division 6.2 is infectious substances: materials that can cause disease, marked with the biohazard symbol. They share the class number but warn about completely different dangers.
The two symbols
What separates the divisions:
| Division 6.1 | Division 6.2 | |
|---|---|---|
| Hazard | Poison (toxic) | Infectious substance |
| Symbol | Skull and crossbones | Biohazard (three crescents) |
| Examples | Toxic chemicals | Regulated medical/biological material |
| Class | Class 6 | Class 6 |
Skull means poison (6.1); biohazard means infectious (6.2). Verify with the official materials.
Why the matching trick works
A matching question can show two Class 6 items and expect you to pair each with the right hazard. If you only read the number, you cannot tell them apart, because both are 6. The symbol is the key: skull for poison, biohazard for infectious. That is exactly the distinction the trick is testing.
Do not confuse 6.1 with toxic gas
One more wrinkle: the skull and crossbones also appears on toxic gas, which is Division 2.3, a Class 2 gas, not Class 6. So a skull alone is not enough; read the class number too. A 6 with a skull is poison (6.1); a 2 with a skull is toxic gas (2.3). Symbol plus number gives the full answer.
How to study and verify
Drill the two Class 6 symbols side by side, skull for poison, biohazard for infectious, and keep the toxic-gas skull (2.3) separate by its number. Note that the hazard symbols are shared internationally, including ADR systems, so the recognition transfers, but confirm the exact exam content and any specifics with the official materials for your test.
Frequently asked questions
- What is the Class 6 symbol-matching trick?
- Class 6 holds two hazards with different symbols: 6.1 poison (skull and crossbones) and 6.2 infectious substances (biohazard). Match by the symbol, not just the number, since both are Class 6. Verify with the official materials.
- What is the difference between 6.1 and 6.2?
- Division 6.1 is poison (toxic solids and liquids, skull symbol); Division 6.2 is infectious substances (biohazard symbol), like regulated medical material. Same class, different symbol and danger.
- Is the skull always Class 6?
- No. The skull and crossbones is on poison 6.1 but also on toxic gas 2.3, which is Class 2. Read the class number too: a 6 is poison, a 2 is toxic gas.
