Sample IFE L2 Fire Science Ops & Safety Practice Questions

Try these sample questions to test your IFE L2 Fire Science Ops & Safety exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A rectangular static water tank measures 4 m long, 2.5 m wide and 1.5 m deep. What is its capacity in cubic metres?

A.15 m³

B.8 m³

C.12 m³

D.22.5 m³

Explanation: Volume of a rectangular tank is length × width × depth: 4 × 2.5 × 1.5 = 15 m³. Firefighters use this calculation when estimating how much open water a tank or pit can supply to a pump.

2A circular hose has an internal diameter of 70 mm. Using π ≈ 22/7, what is the approximate cross-sectional area of the waterway?

A.1,540 mm²

B.3,850 mm²

C.7,700 mm²

D.15,400 mm²

Explanation: Cross-sectional area of a circle is πr². Diameter 70 mm gives radius 35 mm, so (22/7) × 35 × 35 = 3,850 mm². Hose capacity and friction estimates start from this waterway area.

3A pump crew needs to express a foam concentrate mix of 3 parts concentrate to 97 parts water as a percentage of concentrate. What percentage is this?

A.0.3%

B.30%

C.3%

D.97%

Explanation: A 3:97 mix means 3 parts out of 100 total parts are concentrate, which is 3%. Induction settings and proportioner labels commonly use this percentage expression of concentrate strength.

4A triangular roof section has a base of 6 m and a perpendicular height of 4 m. What is its area?

A.10 m²

B.24 m²

C.48 m²

D.12 m²

Explanation: Area of a triangle is (1/2) × base × height: 0.5 × 6 × 4 = 12 m². Geometry of this type appears when estimating cladding, tarpaulins, or ventilation openings on pitched roofs.

5Relative density (specific gravity) of a liquid is best defined as which of the following?

A.The ratio of its density to the density of water

B.Its mass divided by its volume alone

C.Its boiling point compared with ice

D.The force it exerts per unit area

Explanation: Relative density compares a substance's density with that of water at a stated temperature. Values less than 1 float on water; values greater than 1 sink, which is critical for liquid fuel behaviour and spill layering.

6Petrol vapour is generally described as having which vapour-density behaviour relative to air?

A.Lighter than air, so it always rises and disperses harmlessly aloft

B.Heavier than air, so it can collect in low points such as cellars and drains

C.Identical to air, so it mixes uniformly at once with no layering risk

D.So light that it cannot form an ignitable mixture near ground level

Explanation: Petrol vapour is denser than air and tends to flow downhill and pool in basements, pits and drains. That layering behaviour drives search, ventilation and ignition-source control at fuel spills.

7A 2 m³ block of material has a mass of 1,600 kg. What is its density?

A.1,600 kg/m³

B.3,200 kg/m³

C.800 kg/m³

D.0.8 kg/m³

Explanation: Density is mass divided by volume: 1,600 kg ÷ 2 m³ = 800 kg/m³. Density calculations underpin buoyancy, relative density and whether liquids float or sink on water.

8Which statement correctly describes evaporation?

A.A liquid changing to vapour only at its boiling point under all pressures

B.A solid changing directly to a liquid without melting

C.A gas condensing into a solid without first becoming liquid

D.Liquid molecules escaping from the surface into vapour below the boiling point

Explanation: Evaporation is surface change of liquid to vapour that can occur below the boiling point. Cooling by evaporation and vapour production from spills are both important in fire science and spill behaviour.

9Compared with water, a liquid with relative density 0.8 will typically do which of the following when spilled onto a calm water surface?

A.Float as a layer on the water

B.Sink immediately to the bottom

C.Mix instantly and disappear with no layer

D.Freeze into a solid crust

Explanation: Relative density below 1 means the liquid is less dense than water, so it floats as a surface layer. Many hydrocarbon fuels behave this way, which affects foam application and containment tactics.

10In mechanics, power is best defined as which of the following?

A.The total distance moved regardless of force

B.The rate of doing work

C.Mass multiplied by velocity alone

D.Force divided by area

Explanation: Power is the rate of doing work, meaning work done per unit time. Pump output discussions and energy delivery from appliances rely on distinguishing work, energy and power correctly.

About the IFE L2 Fire Science Ops & Safety Exam

The IFE Level 2 Certificate in Fire Science, Operations and Safety (Ofqual 500/5925/7) recognises critical knowledge for firefighter and related fire-sector roles. The syllabus covers fire engineering science (maths, matter, mechanics, heat, combustion chemistry, electricity and hydraulics), fire and rescue operations (incident command, search and rescue, firefighting, BA, ventilation, salvage, water supplies, environment and equipment), and fire safety (construction, means of escape, risk assessment, detection and fixed installations). Recommended preparation is about 180 hours of study plus the 3-hour assessment.

Assessment

One three-hour multiple-choice examination of 120 questions aligned to three syllabus sections: Fire Engineering Science (45), Fire and Rescue Operations (45), and Fire Safety (30). Examinations are provided in English only. Successful candidates receive a Pass (outcomes are not graded). Ofqual qualification number 500/5925/7.

Time Limit

3 hours

Passing Score

At least 50% of available marks (60 correct responses out of 120). Candidates do not need a minimum mark in each section — the overall total determines the Pass.

Exam Fee

£69 standard entry for March and October 2026 sittings (£138 late entry), per the IFE 2026 Qualification Fees schedule. Additional centre/venue charges may apply depending on where you sit. Confirm the current fee when you book. (Institution of Fire Engineers (IFE))

IFE L2 Fire Science Ops & Safety Study Tips from Top Performers

1Map your revision to the three official sections and spend roughly equal time on Fire Engineering Science and Fire and Rescue Operations, with slightly less but still substantial time on Fire Safety, matching the 45/45/30 question split.

2Practise calculation items without a calculator for density, Ohm's Law, hose/tank volume, and basic gas-law relationships, because Section 1 expects accurate mathematical application.

3Use the IFE Elementary Fire Engineering Handbook (IFE 50) and UKFRS Foundation for Incident Command / Hazardous Materials (Section 1) guidance as recommended reading, then self-test with timed mixed-section mocks.
