A.

50psi
B.

40psi
C.

35psi
D.

60psi

Correct Answer
A. 50psi

Explanation
The correct answer is 50psi because the question is asking about the pressure at which 1-3/4 handline tips are pumped. The given answer of 50psi indicates that the handline tips are pumped at a pressure of 50 pounds per square inch.

Master streams and ladder pipes are pumped at?(83)

Correct Answer
80 psi

Explanation
The master streams and ladder pipes are pumped at 80 psi. This pressure is necessary to ensure that an adequate amount of water is being delivered to the fire. It allows the water to reach higher levels and cover a larger area, making it more effective in extinguishing the fire. Pumping at this pressure also helps to maintain a steady flow of water, ensuring that the firefighting operation is efficient and successful.

6.

Heavy appliance friction loss?(83)

Correct Answer
10-25 psi

Explanation
The given answer of 10-25 psi suggests that heavy appliances can experience a loss in pressure due to friction. This means that when water or another fluid passes through pipes or hoses to reach these appliances, the friction between the fluid and the inner surface of the pipes causes a decrease in pressure. This loss in pressure can range from 10-25 pounds per square inch (psi).

At what psi is the come-a-long designed to break at in single/double line?

Correct Answer
2000/4000

Explanation
The come-a-long is designed to break at a pressure of 2000 psi when used in a single line configuration and at a pressure of 4000 psi when used in a double line configuration.

The max draft height is?(66)

Correct Answer
25 feet
25"
25ft
25

Explanation
The correct answer is 25 feet, 25", 25ft, 25. These options all represent the maximum draft height, which is the deepest point of a ship or boat below the waterline. It is likely that the question is asking for the maximum draft height measurement, which can be expressed in different units such as feet, inches, or feet with the abbreviation "ft". Therefore, all of the given options are correct representations of the maximum draft height.

SOG 225 directs the second engine at a highrise to?

Correct Answer
layout and supply the standpipe and/or sprinkler system.

Explanation
SOG 225 is a directive that guides the actions of the second engine responding to a highrise fire. According to this directive, the second engine is responsible for two main tasks: layout and supply the standpipe system and/or sprinkler system. This means that the second engine is tasked with arranging and providing the necessary equipment and materials for the standpipe and/or sprinkler system, which are crucial for firefighting in highrise buildings.

Ladder pipe is pumped at what psi?

Correct Answer
150 psi
150 psi within 100"
150

Explanation
The given answer options suggest that the ladder pipe is pumped at 150 psi. The additional information provided in the options, such as "150 psi within 100", is not clear and may be incomplete or irrelevant. Therefore, the only reliable information is that the ladder pipe is pumped at 150 psi.
