In the nfpa 704 labeling system, a rating of 4 in any quadrant corresponds to:
- The lowest degree of hazard
- The highest degree of hazard
- A moderately high hazard
- A moderately low hazard
The Correct Answer:
2. In the nfpa 704 labeling system, a rating of 4 in any quadrant corresponds to the highest degree of hazard.
NFPA704 stands for National Fire Protection Association’s 704 System. This system is generally used for small containers and storage tanks, as these are the fixed facilities provided during a hazardous incident. This system is also responsible for assisting people in identifying dangerous situations. The system is used voluntarily until any local codes have not been specified.
It is a standardized system where colors and numbers are used as a sign to indicate the hazardous material stored in the containers. The label is diamond-shaped, divided into four quadrants or parts. The rating is generally done on a scale of zero to 4, where zero signifies the most negligible hazard or no unusual hazard, while 4 indicates the severe threat. The number 4 suggests that even a short exposure to this chemical is enough to cause death or severe injury. The number 2 shows moderately dangerous chemicals but has the chance to react and explode violently even in normal conditions.
