Which statement about Division 4.1 hazards in transport is true?

• A. They are always allowed to be transported with non-hazardous goods.
• B. They must be segregated from other dangerous goods.
• C. They require no segregation.
• D. They are exempt from segregation requirements.

Answer: (B)

Segregation from other dangerous goods is required for Division 4.1 hazards, which are flammable solids. These substances can ignite or react with other materials under transport conditions, so separating them from other dangerous goods helps prevent ignition, heat buildup, or hazardous reactions if there’s a leak or spill. The rules specify keeping Division 4.1 materials apart from other dangerous goods and often from certain specific substances, as outlined in the transport regulations’ segregation tables. It’s not correct to say they can always be transported with non-hazardous goods without separation, nor that they require no segregation or are exempt from it.
