HAZWOPER Decontamination Procedures & PPE Usage 2

Question 1

Which decontamination method uses a chemical reaction to neutralize or destroy a contaminant rather than simply removing it?

Accepted Answer

Chemical decontamination

Answer

Chemical decontamination uses reactions such as neutralization, oxidation, or disinfection to destroy or detoxify the contaminant rather than just relocating it.

Question 2

When setting up a decontamination corridor, what is the correct flow of personnel movement?

Accepted Answer

Hot zone through warm zone to cold zone

Answer

Personnel must move from the hot zone through the warm zone (where decontamination occurs) before entering the clean cold zone, preventing contaminant spread.

Question 3

Under OSHA 1910.120, who is ultimately responsible for ensuring that proper decontamination procedures are followed at a hazardous waste site?

Accepted Answer

The employer

Answer

OSHA 1910.120 places ultimate responsibility on the employer to develop and implement a decontamination procedure as part of the site safety and health plan.

Question 4

What is the primary purpose of a 'buddy system' during hazardous waste operations involving PPE?

Accepted Answer

To monitor each other for signs of heat stress or PPE failure

Answer

The buddy system ensures that workers can monitor each other for symptoms of chemical exposure, heat stress, PPE breaches, and other emergencies that workers cannot self-detect.

Question 5

Which of the following best describes 'gross decontamination'?

Accepted Answer

The initial rapid removal of heavy contamination before formal decon procedures

Answer

Gross decontamination is the first rapid step to remove bulk or heavy contamination, typically using large volumes of water, before more thorough decon procedures are applied.
