In which work zone(s) are administrative functions located?

The Support Zone is the correct answer because this area is designated for administrative functions and non-hazardous activities that are essential for the overall operation at a hazardous waste site. This is where personnel not directly involved in hazardous waste handling can carry out their work safely, such as planning, coordination, communication, and resource management.

In contrast, the Exclusion Zone is specifically focused on the area where hazardous materials are present. Personnel working in this zone are often wearing protective gear and are directly involved in handling or assessing hazardous substances. The Contamination Reduction Zone serves as a transition area where workers can remove and decontaminate equipment and personnel before exiting the hazardous area.

Therefore, while the other zones have their respective critical roles in hazardous waste operations, administrative functions are primarily carried out in the Support Zone, making it the correct choice for this question.
