What type of zone is established surrounding a hazardous spill?

The correct choice is based on the concept of establishing a protective area around an incident involving hazardous materials. In the context of emergency response to a hazardous spill, an isolation zone is specifically designated to keep unauthorized personnel and the general public away from the contaminated area. This zone is crucial for ensuring the safety of both responders and civilians by preventing exposure to potentially harmful substances.

The isolation zone is established to contain the hazardous spill and mitigate risks associated with the materials involved. By isolating the area, first responders can work effectively to manage the situation without interference and minimize the chance of further contamination or exposure.

Other choices, while they cite different types of zones that may serve various purposes in emergency management or public health, do not specifically pertain to the immediate safety concerns surrounding a hazardous material spill. For example, a safe zone might be an area designated for recovery or shelter, a buffer zone could imply a neutral space but lacks the strict control of entry that an isolation zone has, and a quarantine zone generally refers to an area where potentially infected individuals or materials are isolated but is not specifically designed for hazardous spills.
