What is the primary purpose of the Hazardous Materials Regulation (HMR)?

The primary purpose of the Hazardous Materials Regulation (HMR) is to provide guidelines for the safe transportation of hazardous materials. This regulation is crucial because it sets forth the requirements for identifying, classifying, packaging, and labeling hazardous materials to ensure their safe movement. The HMR aims to minimize the risks associated with the transportation of these substances, protecting not only those involved in the transportation process but also the general public and the environment.

The focus of the HMR is specifically on the transportation aspect, which makes it distinct from other regulatory frameworks that deal with environmental compliance, waste generation, or non-hazardous substance disposal. While compliance with environmental regulations, responsibilities of waste generators, and the disposal of non-hazardous substances are important issues, they fall outside the primary scope of the HMR and are governed by different laws and regulations. Thus, the emphasis on safe transportation within the HMR is why this choice stands out as the correct answer.
