c.the consignment contains two different dangerous goods
d. the container indicate hazard labels of residue from the previous cargo
Answer (2)
Answer:The correct answer is b. dangerous goods have a subsidiary risk.Some dangerous goods may have a primary hazard and a secondary (subsidiary) risk, requiring two labels to indicate both hazards.
Answer:The correct answer is (c) the consignment contains two different dangerous goods. Here's why: - Dangerous Goods Classification: Dangerous goods are categorized based on their primary hazards (e.g., flammable, corrosive, toxic, explosive).- Multiple Labels: If a consignment contains two or more substances with different hazard classifications, it requires separate hazard labels for each. This ensures clear communication of the specific risks involved. Let's consider why the other options are incorrect: - (a) dangerous goods have 2 main hazards: While a dangerous good might have multiple hazards, the main hazard is what it's classified under. The secondary hazards might be considered subsidiary risks.- (b) dangerous goods have a subsidiary risk: Subsidiary risks are usually addressed within the primary hazard class. A separate label is generally not required for subsidiary risks unless they are significant enough to warrant a distinct hazard classification.- (d) the container indicates hazard labels of residue from the previous cargo: While residue can be a concern, it's unlikely to trigger separate labels unless the residue itself poses a significant hazard. In summary: Double hazard labels on a consignment of dangerous goods indicate the presence of two or more substances with distinct hazard classifications, requiring separate warnings.
