All Correct Answers
Lesson Description correct answer -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: correct answer -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 correct answer -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.
Lesson Focus
This lesson focuses on the following topics: correct answer -Site Control
Program
Site Work Zones
Site Security
, Site Control Program
Site control regulations listed in 29 CFR 1910.120 are intended to reduce
worker and public exposure to chemical, physical, biological, radiological, and
safety hazards. Site control is especially important in emergency situations.
correct answer -The level of site control needed depends on:
Site characteristics
Site size
Surrounding community
Site Maps correct answer -The site map is an essential piece of the site
control program. The map serves as a central source of information about the
site and can help personnel plan and organize activities. By using the map,
issues are identified, such as access and evacuation routes and areas requiring
the use of personal protective equipment (PPE). This makes the site map an
excellent resource and supplement for daily safety/health briefings of field
teams. The site map should be developed prior to the initial site entry using
information from the preliminary evaluation.

Site Preparation correct answer -The preparation of a site for clean-up
activity is just as critical as the cleanup itself. Proper preparation is necessary
to ensure that emergency response operations go smoothly and that workers
are protected. If site preparation is not conducted properly, the health of
those doing the preparation as well as those doing the cleanup can be
endangered. Some major steps in site preparation include:
The construction of roadways
The elimination of physical hazards
Installing skid resistant strips on slippery surfaces
Site Work Zones correct answer -To reduce the spread of hazardous
substances in a contaminated area, work zones should be established. As
many work zones can be established as are needed to meet operational and
safety objectives. Separate zones are created to distinguish different levels of
personal protective equipment, or PPE. To prevent cross-contamination,
workers and equipment should not be transferred between zones.
Establishing work zones ensures:
