Which of the following is a component of a proper packing method for dangerous goods?

Using adequate cushioning and secure seals is a fundamental component of a proper packing method for dangerous goods because it ensures the safety and integrity of the contents during transportation. Dangerous goods often possess inherent risks, either due to their physical characteristics or their potential to react adversely with other materials. Proper cushioning protects these goods from physical impacts, shifting during transit, and potential damage. Secure seals are equally important, as they prevent leaks or spills, which could lead to environmental hazards or health risks. This combination not only complies with regulatory requirements but also demonstrates a commitment to safety for all parties involved in the transportation process.
