Which of the following correctly describes the potential of Class 6.2 materials?

Class 6.2 materials are classified as infectious substances, which specifically include agents that are capable of causing infections in living organisms, including humans. These materials can harbor pathogens such as bacteria, viruses, or fungi that can lead to disease. The correct answer reflects the nature of these substances, as they can be transmitted through various means, potentially resulting in an infection if exposure occurs.

The other potential choices do not accurately capture the essence of Class 6.2 materials. While some may indeed cause allergic reactions or contribute to fatal diseases, the primary hazard associated with these materials is their ability to cause infections, which is why they are categorized specifically under this class. Additionally, stating that they pose no health risk fails to acknowledge their infectious nature and the significant threat they can present in certain situations.
