  1. Welcometo Hazardous Materials Technician - Part 1

  2. General • Without reference determine general principles of the Hazardous Materials Technician with at least 80% accuracy.

  3. INTRODUCTION • Hazardous materials technicians shall be trained to meet all competencies at the first responder awareness and operational levels and the competencies of this chapter. Hazardous materials technicians also shall receive any additional training to meet applicable … appropriate state, local, or provincial occupational health and safety regulatory requirements.

  4. DEFINITIONS • Hazardous materials technicians are those persons who respond to releases or potential releases of hazardous materials for the purpose of controlling the release. • Hazardous materials technicians are expected to use specialized chemical protective clothing and specialized control equipment.

  5. GOAL • The goal of this chapter shall be to provide the hazardous materials technician with the knowledge and skills to perform the following tasks safely. Therefore, in addition to being competent at both the first responder awareness and operational levels, the hazardous materials technician shall be able to:
