The maximum pressure that a DOT 407/MC307 tank truck can carry is 40 psi. This type of tank truck is designed for the transport of hazardous materials, specifically liquids that can be classified as corrosive, flammable, or toxic. The construction of these tanks allows them to safely handle the pressures associated with these materials.

The 40 psi limit is important because it ensures the integrity and safety of the tank under normal operating conditions. This standard is set to prevent structural failure of the tank during transportation. It is critical for hazmat technicians to understand these specifications to assess the safe handling, transportation, and potential hazards related to the materials being transported.

Knowing the pressure limits helps in determining the appropriate emergency response if a leak or rupture occurs. Therefore, understanding the pressure capacities, along with the design and function of DOT 407/MC307 tanks, equips hazmat responders with the necessary information to manage incidents effectively.
