What information is typically found on a hazardous materials label?

The correct choice highlights that hazardous materials labels contain critical information about emergency response protocols and handling precautions. This information is essential for anyone who may come into contact with the materials, including drivers, handlers, and emergency responders. It guides users on how to safely manage the substance, including what personal protective equipment is necessary, how to mitigate potential risks, and what to do in case of an emergency like a spill or exposure.

In comparison, the other options do not address the fundamental purpose of hazardous materials labels, which is to ensure safety and compliance during handling and transportation. The cost of the materials is irrelevant to their safe use. Storage instructions are indeed important but are just one part of the broader required information on a label. Lastly, while manufacturing details may be included for traceability, they do not provide the immediate safety and response information crucial for dealing with hazardous substances effectively.
