Final answer:
Before transporting a sealed load, confirm the seal's authenticity, ensure the load is properly secured, and if applicable, verify that placard numbers match the seal numbers for compliance and cargo integrity.
Step-by-step explanation:
Before transporting a sealed load, there are several key factors you must check to ensure the safety and security of the cargo. Firstly, you should verify that the seal is authentic to guarantee that the contents have not been tampered with since they were packed. Secondly, it's crucial to confirm that the load is properly secured within the transportation vehicle to prevent shifting or damage during transit.
Lastly, for loads that require placards due to hazardous materials or other specific regulations, you need to ensure that the placard numbers match the seal numbers, which serves as an additional check that the load has been handled correctly and corresponds to the transport documentation. These checks are necessary to comply with transportation regulations and to maintain the integrity of the cargo.
