Hazmat Technician - PassRun

Everything you need for the Korean Hazardous Materials Industrial Engineer
written exam, in one app.

180 questions with full explanations, laid out to follow the official syllabus
of the Human Resources Development Service of Korea (2025-2029) — 3 subjects and
24 topics. No sign-up. No internet connection required.

■ Built on the latest amended regulations
· Designated quantities per Enforcement Decree of the Hazardous Materials Safety
Management Act, Table 1 (amended 30 April 2024)
· Class 5 self-reactive substances are no longer 10/100/200 kg per item — they
are now Type 1 (10 kg) / Type 2 (100 kg)
· Updated Korean chemical nomenclature reflected throughout
Many study materials still carry the old figures, so this was checked carefully.

■ A CBT mock exam just like the real thing
· 60 questions across 3 subjects, exactly as in the real exam (90-minute timer)
· The same OMR answer-sheet screen used in the actual CBT
· Enough questions for 3 full mock exams with no repeats
· Leave mid-exam and resume where you left off

■ Subject cutoff judged correctly
To pass you need an average of 60 or more AND at least 40 in every subject —
fall below 40 in any one subject and you fail, whatever your average.
· A 40-point line and a "cutoff" badge on each subject bar
· Marked as failed if any subject is below 40, even with an average above 60
· Applied only to mock exams covering all 3 subjects

■ Wrong-answer notes that clear themselves
· Questions you get wrong are collected automatically
· Answer one correctly 3 times in a row and it graduates off the list
· Add your own memo to any question
· Filter by subject, sort by most-missed

■ Study by subject
· Subject 1 — Physical and chemical properties of matter
· Subject 2 — Fire prevention and extinguishing methods
· Subject 3 — Properties and handling of hazardous materials (Classes 1-6,
transport, facility standards, administration)
· Broken into 24 topics for short sessions
· Pick an answer and see the correct one with its explanation immediately

■ Statistics that show your weak spots
· Automatic weak-subject analysis from your accuracy per subject
· Mock exam score trend graph
· Two-week study volume and study streak
· "Weak-point drill" that gathers only your lowest-accuracy questions

■ And more
· Random exams — choose the range and question count (10-60)
· Bookmarks for questions you keep second-guessing
· Full-text search across question text, options and explanations
· Dark mode and adjustable text size
· Shuffle questions and options so you learn the content, not the position

■ Multilingual, for learners from abroad
· 한국어 / English / Tiếng Việt / ไทย / Bahasa Indonesia / 中文
· All 180 questions translated into 5 languages (English, Tiếng Việt, ไทย, Bahasa Indonesia, 中文)
· The real exam is in Korean, so a side-by-side mode shows the Korean original
beneath the translation

■ Advertising enquiries for training centres
The "Training" tab is the channel for training centres to ask about in-app
advertising and partnerships — we will share placements, periods and rates.
Learners can use the same tab to report an error in a question.
