What is one of the primary responsibilities of a contractor regarding hazardous materials?

The primary responsibility of a contractor regarding hazardous materials is to follow proper handling procedures. This entails ensuring that all hazardous materials are managed according to safety regulations and industry standards to protect workers, the environment, and the general public. Proper handling procedures include safely storing, transporting, and using hazardous substances, as well as implementing the necessary safety measures to mitigate risks of exposure or accidents.

Following these procedures is crucial because mishandling hazardous materials can lead to serious health risks for workers and bystanders, environmental contamination, and potential legal consequences for the contractor. Hence, adherence to regulations and established protocols is an essential aspect of a contractor's role in managing hazardous materials on-site.
