Sample questions

Three questions in the style of the exam, with the answer and the reference. The real paper has 50 and is harder.

Q1Erecting a tube-and-coupler scaffold with hand spanners in a restricted area. Which permit?
  1. Hot Work, Form 9873-2
  2. Cold Work, Form 9873-3
  3. Confined Space Entry, Form 9873-4
  4. Line Break, Form 9873-1

Answer: Cold Work, Form 9873-3. CSM I-4 lists scaffold erection or dismantling under the Cold Work Permit (Form 9873-3, blue). An engine, a grinder or an unrated tool makes it hot work. CSM I-4 (July 2017) 4.5.1. Verify against the latest edition.

Q2Top lift readings: O2 20.6%, LEL 2%, H2S 4 ppm. Can a welder tack a bracket there?
  1. Yes, every reading is normal
  2. Yes, with a fire watch
  3. No: hot work needs 0% LEL
  4. Only in breathing apparatus

Answer: No: hot work needs 0% LEL. Hot work is not permitted above 0% LEL. Cold scaffold work may go on: all readings are in the no-respirator band. CSM I-4 4.10.4; CSM I-6 (December 2025) 6.7.9. Verify against the latest edition.

Q3A detector reads 1,050 ppm of a gas whose LEL is 2.1% by volume. What is the %LEL?
  1. 1%
  2. 5%
  3. 10%
  4. 21%

Answer: 5%. LEL = 2.1 × 10,000 = 21,000 ppm; 1,050 ÷ 21,000 = 5% LEL: breathing apparatus for the crew, no hot work. CSM I-6 6.7.9; CSM I-4 4.10.4–4.10.5. Verify against the latest edition.
