Which hazardous materials categories should never exceed 100 pounds in a passenger bus?

Class 6 poisons, which are toxic materials, pose a significant risk to public safety and health, particularly in a passenger bus environment where individuals are highly vulnerable. This classification includes harmful substances that can cause serious harm through inhalation, ingestion, or skin contact. For safety reasons, the regulations stipulate that these materials should never exceed 100 pounds on passenger buses to minimize the potential for exposure and mitigate the risks associated with accidental release or contamination.

By limiting the amount of Class 6 poisons transported on a passenger bus, the regulations aim to protect both passengers and the driver from potential hazardous incidents. This ensures a safer travel environment and aligns with safety protocols that seek to reduce risks associated with transportation of dangerous goods.
