Korean Firefighter Open Recruitment Examination common mistakes
Korean Firefighter Open Recruitment Examination · Understand the traps and how to avoid them.
Treating one smoke color as a complete diagnosis
Smoke appearance alone cannot establish the full fuel, ventilation and thermal conditions.
What to do instead
Evaluate the whole situation through trained procedures and preserve uncertainty.
Using Celsius directly in a fourth-power radiation ratio
The physical relation requires an absolute temperature scale.
What to do instead
Convert the supplied temperatures to kelvin before applying the model.
Assuming identical settings for every suppression system
Design, agent, configuration and applicable criteria can require different controls.
What to do instead
Use the approved documents and current applicable technical provisions.
Calling a reset proof of repair
Clearing an indication does not demonstrate that the cause has been found or the function restored.
What to do instead
Investigate the cause, perform the required verification and record restoration.
Using a foreign fire-code number as Korean law
Similar technical aims do not make foreign enactments or installation thresholds legally interchangeable.
What to do instead
Identify the applicable Korean law, NFPC or NFTC and its current edition.
Assuming a beneficial purpose creates unlimited power
A desirable fire-safety objective does not remove legal limits or procedural duties.
What to do instead
Identify authority and assess the particular measure under the relevant legal principles.
Adding unlike material quantities without reference values
Liters and kilograms of different materials do not directly form a meaningful compliance multiple.
What to do instead
Divide each amount by its own applicable reference quantity before summing.
Selecting an agent without identifying the substance
A reactive material can produce additional hazards when exposed to an unsuitable agent.
What to do instead
Use material-specific documentation and the appropriate trained response arrangements.
