1A firefighter is coupling lengths of hose. If they connect three 15-meter lengths and two 30-meter lengths, what is the total length of the hose line?

A.75 meters

B.105 meters

C.90 meters

D.120 meters

Explanation: To find the total length, multiply the number of hoses by their respective lengths and sum them: (3 * 15) + (2 * 30) = 45 + 60 = 105 meters.

2A water tank with a capacity of 4,000 liters is 75% full. How many liters of water are in the tank?

A.2,500 liters

B.3,000 liters

C.3,200 liters

D.3,500 liters

Explanation: To find 75% of 4,000 liters, multiply 4,000 by 0.75: 4,000 * 0.75 = 3,000 liters.

3A pump discharges water at a rate of 250 liters per minute. How long will it take to discharge 1,500 liters of water?

A.4 minutes

B.5 minutes

C.8 minutes

D.6 minutes

Explanation: To find the time required, divide the total volume by the discharge rate: 1,500 liters / 250 liters per minute = 6 minutes.

4If a firefighter works a 10-hour shift and spends 2.5 hours on equipment maintenance, what percentage of the shift was spent on maintenance?

A.25%

B.15%

C.20%

D.30%

Explanation: To find the percentage, divide the maintenance hours by the total shift hours and multiply by 100: (2.5 / 10) * 100 = 25%.

5A fire appliance travels at an average speed of 60 km/h to reach an incident that is 15 kilometers away. How many minutes will the journey take?

A.10 minutes

B.12 minutes

C.15 minutes

D.20 minutes

Explanation: To find the travel time, divide distance by speed: 15 km / 60 km/h = 0.25 hours. Convert this to minutes by multiplying by 60: 0.25 * 60 = 15 minutes.

6A foam concentrate must be mixed with water at a ratio of 3:97 (3% foam to 97% water). To produce 500 liters of foam solution, how many liters of foam concentrate are required?

A.10 liters

B.20 liters

C.15 liters

D.30 liters

Explanation: The concentration is 3% of the total solution. To find the required concentrate for 500 liters: 500 * 0.03 = 15 liters.

7A fire pump operating at 1,000 kPa pressure loses 50 kPa of pressure due to friction for every 30 meters of hose. If the hose line is 120 meters long, what is the pressure at the nozzle?

A.800 kPa

B.750 kPa

C.850 kPa

D.900 kPa

Explanation: The hose line has a length of 120 meters, which contains four 30-meter segments (120 / 30 = 4). The pressure loss is 4 * 50 kPa = 200 kPa. The pressure at the nozzle is 1,000 kPa - 200 kPa = 800 kPa.

8If 4 firefighters can complete a safety inspection of a commercial building in 3 hours, how many hours would it take 6 firefighters to complete the same inspection, assuming they work at the same rate?

A.1.5 hours

B.2.5 hours

C.2 hours

D.4.5 hours

Explanation: The total work required is measured in firefighter-hours: 4 firefighters * 3 hours = 12 firefighter-hours. To find the time for 6 firefighters, divide the total work by 6: 12 firefighter-hours / 6 firefighters = 2 hours.

9A chemical container is leaking at a rate of 150 mL per minute. If the leak started at 14:15 and is stopped at 16:45, what is the total volume of chemical that leaked, in liters?

A.22.5 liters

B.15.0 liters

C.18.5 liters

D.25.0 liters

Explanation: The leak duration is from 14:15 to 16:45, which is 2 hours and 30 minutes, or 150 minutes. At a rate of 150 mL per minute, the total volume leaked is 150 * 150 = 22,500 mL. Convert this to liters by dividing by 1,000: 22,500 / 1,000 = 22.5 liters.

10A rescue team needs to raise a load using a pulley system. The load weighs 240 kg. If a 3:1 mechanical advantage system is used, and friction adds 10% to the required effort, how much force (in kg of effort) is required to raise the load?

A.72 kg

B.80 kg

C.96 kg

D.88 kg

Explanation: With a 3:1 mechanical advantage, the ideal force required is 240 kg / 3 = 80 kg. Friction adds 10% of this ideal force: 80 * 0.10 = 8 kg. The total effort required is 80 + 8 = 88 kg.

Frequently Asked Questions

What is the DFES WA Career Firefighter Aptitude Test?

The DFES WA Career Firefighter Aptitude Test is a key cognitive and psychometric stage of the Western Australia firefighter recruitment process. It is used to filter candidates based on numerical, verbal, abstract, mechanical, and situational safety reasoning before progressing them to physical testing.

Are the DFES WA psychometric tests game-based?

Yes, DFES WA utilizes modern psychometric suites including game-based cognitive tests (such as Cognify) and emotional intelligence tests (such as Emotify) to assess spatial, numerical, verbal, and behavioral traits in dynamic settings.

What is a passing score for the DFES firefighter test?

DFES WA does not publish a specific passing percentage. Because the recruitment process is highly competitive, candidates are ranked, and only those scoring in the top bands are invited to progress to the Physical Aptitude Test (PAT) and interviews.

How long are the DFES cognitive test results valid?

Results for the psychometric and cognitive assessments are typically valid for 12 months. If you sit the test, your result is locked for that duration, meaning you cannot re-sit the test within the same recruitment cycle to improve your score.

Does the test include mechanical reasoning?

Yes, understanding physical principles is a core component. The test includes questions on simple machines (levers, gears, pulleys), gravity, friction, pressure, and basic electricity, reflecting the practical mechanical requirements of firefighting.

What are the eligibility requirements for WA Career Firefighters?

Candidates must have at least completed Year 10 or equivalent, hold an unrestricted Western Australian Light Rigid (LR) class driver's license (or higher), hold Australian Citizenship or Permanent Residency, and pass comprehensive health and fitness evaluations.
