Sample questions
Three questions in the style of the exam, with the answer and the reference. The real paper has 50 and is harder.
Q1A 9 m scaffold that is not special: the Supervisor has signed the green tag. What happens next?
- He inserts it; an Inspector co-signs at the next visit
- A certified Inspector inspects, co-signs, dates and inserts it
- The proponent inserts it after reading the checklist
- The user's foreman inserts it after a pre-use check
Answer: A certified Inspector inspects, co-signs, dates and inserts it. Over 6 m the Supervisor hands the signed tag to a certified Inspector, who inspects, signs and inserts it. GI 8.001 (2025) §9.3.3, §9.4. Verify against the latest edition.
Q2600 m³ of scaffold at 6 m³ per productive scaffolder per shift. Crew of 6 with one non-productive chargehand, 25% lost time. Whole shifts needed?
- 17
- 22
- 27
- 34
Answer: 27. 5 productive × 6 m³ × 0.75 = 22.5 m³ per shift; 600 ÷ 22.5 = 26.7 → 27 shifts. Example data, AL-YASSIN Operations course. Verify against the latest edition.
Q3216 of 240 delivery lines arrived on time and complete. What is the OTIF?
