Answer: (C)

The three main types of decontamination are emergency, mass, and technical.

Emergency decontamination is typically performed quickly at the scene of a hazardous materials incident to remove contaminants from individuals who have been exposed. This is a vital first step that helps minimize harm while ensuring that affected individuals can receive further medical attention without carrying harmful substances.

Mass decontamination is a systematic approach utilized to decontaminate a large number of people simultaneously, often following an incident involving chemical exposure. This method employs established procedures and equipment to efficiently manage and treat large groups.

Technical decontamination refers to more thorough procedures that are conducted after the immediate threat has been addressed. This type involves the use of specialized equipment and techniques to ensure that all contaminants are effectively removed, particularly in cases where the materials involved have long-lasting effects or require special handling due to their hazardous nature.

Understanding these three types of decontamination is crucial for effective response to hazardous materials incidents, as each type serves a specific purpose in protecting public health and safety.
