Shippers typically send hazardous materials by truck, rail, vessel, or airplane due to the specific requirements and regulations surrounding the transportation of such materials. Each of these methods is equipped to handle the unique challenges presented by hazardous substances, including safety measures and proper containment.

Trucking is one of the most common methods because it allows for direct and flexible transport to various destinations. Rail transport is also utilized for large volumes of hazardous materials, which can provide efficient long-distance shipping. Vessels are necessary for shipping hazardous materials internationally over water, adhering to maritime safety regulations. Lastly, air transport, while more limited due to stricter regulations, is essential for expedited shipments of hazardous materials that require quick delivery.

Each of these transportation modes is governed by specific regulations that ensure safety during transit, which is why they are preferred methods for shipping hazardous materials. Other options, such as public transportation, using volunteers, or relying solely on postal services, do not meet the regulatory requirements or safety considerations necessary for handling hazardous materials.
