HAZWOPER 40 - Lesson 9: Site Control
HAZWOPER 40 - Lesson 9: Site Control
Lesson Description
This lesson, Site Control, explains how to set up a site control program designed to
reduce worker and public exposure to chemical, physical, biological, and safety
hazards at hazardous waste sites. It discusses why and how to create safety zones
(i.e., Exclusion Zone, Contamination Reduction Zone, and Support Zone) to ensure
a safe environment for support staff and to fight against cross-contamination from
those entering/exiting hot zones. Finally, it reviews the importance of having
effective site security procedures to keep unauthorized outsiders who are most
often not protected, away from exposure.
Learning Objectives
At the completion of this lesson, you will be able to:
List the three objectives that a hazard work zone should ensure.
Describe the three most commonly used areas of a hazard work site.
Summarize the distinctive characteristics and purpose of a Contamination
Reduction Zone (CRZ).
Name five functions of tasks associated with a support zone.
Explain four reasons for establishing effective internal communication.
Introduction
Most activities in a hazard area should be restricted to a few key workers who
perform collectively in line-of-sight communication with a command post. Zones
within the site are created to meet operation and safety objectives, and site maps
designate characteristics of the site itself and of the surrounding community. The
primary focus is that nothing unauthorized comes in or out.
