Final answer:
In the WHMIS system, class F refers to Dangerously Reactive Material. Option B from the provided choices, 'Dangerously reactive material,' is the correct answer. Classes for compressed gas and oxidizing material are separate from Class F.
Step-by-step explanation:
WHMIS class F specifically refers to Dangerously Reactive Material. Under this classification, the materials included are those that can undergo vigorous polymerization, decomposition or condensation, can become self-reactive under conditions of shock or an increase in pressure or temperature, or are sensitive to static discharge. This would include certain binary compounds, elements that react vigorously with oxygen, and other substances that can pose significant reactive hazards.
As for the options provided in the question:
- A. Compressed gas - This is incorrect as compressed gases are typically classified under a different WHMIS class.
- B. Dangerously Reactive Material - This is the correct answer. WHMIS class F materials can indeed be dangerously reactive.
- C. Oxidizing material - While oxidizing materials can cause other materials to combust and are certainly hazardous, they are classified under a different WHMIS class.
- D. None of the above - This is incorrect because option B is the right choice.
