Chapter 34 Hazardous Materials: Decontamination Techniques

A contaminated victim coming into physical contact with a rescuer is an example of

cross-contamination

A responder grabs a tool that was used to handle a hazardous material. This is an example of

cross-contamination

After undergoing decontamination, responders should report to the

EMS station

Pathogens

As a decontamination technique, disposal is a _____-step process

two

Compared to gross decontamination, technical decontamination

is more thorough

Disposal is used for items that

cannot be properly decontaminated

Following mass decontamination, victims should be directed to the

triage area

HEPA filter efficiency is measured in units of

microns

Which phrase summarizes the mass decontamination procedure

Strip, flush, and cover

Which statement about disposal of absorbent materials that have been used in a decontamination process is correct

Care must be taken to comply with applicable laws and regulations.

Which statement about runoff during emergency decontamination is correct

An effort should be made to divert runoff from drains, streams, or ponds.

Which statement about solidification of a hazardous liquid is correct

It makes the material easier to handle.

Which step should be taken first as personnel leave the hot zone

Tools placed in the tool drop

Which technique is commonly used for gross decontamination

A shower system
