10+ Fire Fighting Engineer Interview Questions and Answers

2-stroke engines have a power stroke every revolution, while 4-stroke engines have a power stroke every other revolution.

• 2-stroke engines have a simpler design with fewer moving parts compared to 4-stroke engines.

• 2-stroke engines require a fuel-oil mixture for lubrication, while 4-stroke engines have a separate oil reservoir.

• 2-stroke engines are lighter and more compact than 4-stroke engines, making them popular in applications where weight and size are critical.

• 2-stroke engi...read more

Answering questions related to fire fighting engineering

• To read piping drawing, understand symbols and abbreviations used

• Material of pipe used in fire fighting can be steel, copper, or plastic

• Types of sprinkler include pendant, upright, sidewall, and concealed

The Iron-Carbide (Fe-C) diagram is a graphical representation of the phases and microstructures that form as a function of temperature and carbon content in iron-carbon alloys.

• The Fe-C diagram shows the phases of iron and carbon at different temperatures and carbon concentrations.

• It helps in understanding the microstructure and properties of steel and cast iron.

• The diagram consists of regions such as austenite, ferrite, cementite, and pearlite.

• For example, at low carbon conte...read more

The different types of sprinklers include upright, pendant, sidewall, and concealed sprinklers.

• Upright sprinklers are installed at the top of a room and spray water upwards.

• Pendant sprinklers hang down from the ceiling and spray water downwards.

• Sidewall sprinklers are mounted on the walls and spray water horizontally.

• Concealed sprinklers are hidden behind a decorative cover and activate when the temperature rises.

Spray line work involves operating and maintaining fire hoses and nozzles to extinguish fires.

• Spray line work includes connecting hoses to water sources, aiming nozzles at the base of the fire, and controlling water flow.

• Firefighters must be trained in proper techniques for using spray lines to effectively combat fires.

• Regular maintenance of hoses and nozzles is essential to ensure they function properly during emergencies.

A jockey pump is a small pump used to maintain pressure in a fire protection system.

• Jockey pumps are typically used in conjunction with larger fire pumps to ensure a constant pressure in the system.

• They are usually set at a lower pressure than the main fire pump to prevent frequent starts and stops.

• Jockey pumps are often used in high-rise buildings, industrial facilities, and other locations where maintaining pressure is critical.

• Examples of jockey pump brands include Grundfo...read more

Firefighting is the practice of extinguishing fires to protect life, property, and the environment.

• Firefighting involves using various techniques and equipment to extinguish fires.

• Firefighters may use water, foam, or chemical agents to put out fires.

• Firefighting also includes search and rescue operations, ventilation, and salvage operations.

• Firefighters are trained to assess the situation, develop a plan of action, and execute it safely and efficiently.

Fire execution refers to the process of carrying out firefighting operations to extinguish a fire.

• Fire execution involves assessing the situation, determining the best approach, and implementing firefighting tactics.

• It may include tasks such as deploying fire hoses, using fire extinguishers, and coordinating with other emergency responders.

• Proper training, equipment, and communication are essential for successful fire execution.

• Example: Firefighters responding to a structure ...read more

A fire protection system that uses water mist to suppress fires

• Spray system uses fine water droplets to extinguish fires

• It is effective in suppressing fires in enclosed spaces

• Commonly used in areas where traditional sprinkler systems may cause water damage

• Examples include high-pressure water mist systems and low-pressure water mist systems
