The correct answer is B. In wide-open spaces, the sound pressure level (SPL) decreases by 6 decibels (dB) every time the distance from the source is doubled. This is known as the inverse square law of sound propagation, which states that the intensity of sound is inversely proportional to the square of the distance from the source.For example, if the SPL at 1 meter from the source is 100 dB, then the SPL at 2 meters from the source is 94 dB, and the SPL at 4 meters from the source is 88 dB123

Scenario groupings is a data analysis approach that provides the broadest perspective of a fire problem by identifying and comparing different types of fire incidents based on their characteristics, such as ignition source, fuel, location, time, and outcome. This approach can help reveal patterns, trends, and relationships among fire scenarios and support fire prevention and protection strategies.References:Fire Data Analysis Handbook, Chapter 5: Scenario Groupings; [Fire Protection Handbook], Section 2, Chapter 3: Fire Data Collection and Analysis.

Fire pump

A suction in-line fire pump has a pressure range that can exceed 300 psi (2,068 kPa). This type of pump is a centrifugal pump that is installed in a vertical position with the suction and discharge connections in the same line. The pump is designed to handle high pressures and flows, and it is suitable for high-rise buildings and other applications that require high head.According to NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, a suction in-line fire pump can have a rated pressure of up to 360 psi (2,482 kPa)1.The other types of fire pumps mentioned in the question have lower pressure ranges, as shown in the table below2:

The background color used from the source to the outlets of a nitrous oxide medical gas system is blue. This is the standard color coding for nitrous oxide cylinders and pipelines in medical gas pipeline systems12. The color coding helps to identify the gas type and prevent accidental misconnections or cross-contamination3. The color coding also indicates the pressure and flow characteristics of the gas system4. References:
