✍️ Sample CES Questions & Answers

1. Which factor does NOT affect blast damage severity?
✓ Color of the explosive

The color of an explosive material is a superficial characteristic that has no bearing on the physical severity or destructive power of a blast. Blast damage severity is determined by intrinsic properties like the amount and type of explosive, the distance from the blast site, and environmental factors such as wind and terrain, which influence the propagation of the blast wave.

2. When budgeting for an explosives operation, which cost category is MOST often underestimated by new blasting managers?
✓ Regulatory compliance, licensing, and insurance costs

Compliance, licensing renewals, insurance premiums, and regulatory audit costs are frequently overlooked but can represent a significant portion of operational overhead.

3. What is residual risk?
✓ The risk remaining after mitigation measures have been applied

Residual risk is what remains after mitigation measures are applied, and it must be accepted, further reduced, or transferred based on organizational risk tolerance.

4. Which explosive compound is the main ingredient in detonating cord (PETN cord)?
✓ PETN

Detonating cord contains a core of Pentaerythritol Tetranitrate (PETN), a primary-secondary high explosive with high VoD.

5. What is the consequence of practicing outside the defined scope of practice?
✓ Potential license revocation, legal liability, and risk to public safety

Practicing outside scope carries serious consequences including license revocation, legal liability, and potentially endangering the public, regardless of the outcome.

6. Which of the following is classified as a primary explosive due to its extreme sensitivity to initiation stimuli?
✓ Lead azide

Lead azide is a primary explosive that is highly sensitive to heat, friction, and impact, making it suitable for use in detonators.

  • A printable CES cheat sheet you can print or save as a PDF.
  • CES flashcards built from the same question bank.
  • Free CES practice tests with the correct answer shown after each question.
