Question

If another aboveground storage tank contains a radioactive material that poses an extreme hazard to those who do not wear protective gear, which of the choices below would best identify the substance in question according to the 704 labeling system?

A. The blue quadrant must demonstrate a signal of 3 or 4 coupled with the radioactivity insignia in the bottom quadrant of the placard.

B. The blue quadrant must demonstrate a signal of 1 or 2 in conjunction with the yellow quadrant bearing the insignia for radioactivity.

C. The red quadrant must show a high number to indicate an extreme reactivity due to the presence of radiation.

D. All quadrants should be marked with a high signal due to the radioactivity involved.

Answer 1

According to the NFPA 704 labeling system, the substance in question, which is a radioactive material posing an extreme hazard to those without protective gear, would be best identified by Option A. The blue quadrant on the placard must have a signal of 3 or 4, indicating a high health hazard, coupled with the radioactivity insignia in the bottom quadrant.

Step-by-step explanation:

According to the NFPA 704 labeling system, the substance in question, which is a radioactive material posing an extreme hazard to those without protective gear, would be best identified by Option A. The blue quadrant on the placard must have a signal of 3 or 4, indicating a high health hazard, coupled with the radioactivity insignia in the bottom quadrant.

This indicates that the substance is highly radioactive and requires protective gear to handle safely. The other options do not accurately describe a substance with the same level of hazard.
