Question 1
What is the primary purpose of a demolition engineering survey before starting
work?
A. To estimate material resale value
B. To identify structural hazards and plan safe demolition methods
C. To determine worker wages
D. To schedule equipment rentals
Correct Answer: B
Rationale: A demolition engineering survey is conducted to evaluate structural
integrity, identify hazards such as load-bearing elements, utilities, hazardous
materials, and collapse risks, and to develop a safe, controlled demolition plan.
This ensures worker safety, regulatory compliance, and prevents unintended
structural failure. Other options are secondary or unrelated to safety-critical
planning.
Question 2
Which agency typically regulates workplace safety during demolition activities in
Colorado?
,A. EPA
B. OSHA
C. DOT
D. FEMA
Correct Answer: B
Rationale: OSHA (Occupational Safety and Health Administration) establishes
and enforces workplace safety standards, including demolition operations. It
regulates fall protection, structural stability, and hazard communication. EPA
handles environmental concerns, DOT manages transport, and FEMA deals with
disaster response, not routine demolition safety enforcement.
Question 3
Before demolition begins, utilities should be:
A. Temporarily rerouted by workers on site
B. Left active for emergency use
C. Properly disconnected and verified by utility providers
D. Covered with soil or debris
Correct Answer: C
Rationale: All utilities such as gas, water, electricity, and telecommunications
must be properly disconnected and verified by authorized utility companies to
prevent explosions, electrocution, flooding, or service disruptions. Improper
handling poses severe life-threatening hazards.
Question 4
Which of the following is the most critical PPE for demolition workers?
A. Sunglasses
B. Steel-toe boots, hard hat, gloves, and eye protection
,C. Rain boots only
D. Lightweight clothing
Correct Answer: B
Rationale: Demolition environments expose workers to falling debris, sharp
materials, dust, and electrical hazards. Full PPE including hard hats, steel-toe
boots, gloves, and eye protection is essential for minimizing injury risk.
Question 5
What is the first step in a controlled demolition plan?
A. Removing debris
B. Structural analysis and hazard assessment
C. Installing fencing
D. Ordering dumpsters
Correct Answer: B
Rationale: Structural analysis and hazard assessment determine load-bearing
components, collapse patterns, and risks. This foundational step ensures the
demolition is executed safely and systematically.
Question 6
Which method is commonly used for large building demolition in urban areas?
A. Implosion using explosives
B. Manual hammering only
C. Water erosion
D. Free falling by removing random supports
Correct Answer: A
, Rationale: Implosion uses carefully placed explosives to collapse structures
inward, minimizing damage to surrounding buildings. It is controlled,
engineered, and commonly used in dense urban environments.
Question 7
What is the purpose of a demolition permit?
A. To allow waste dumping
B. To legally authorize demolition work under safety regulations
C. To increase property taxes
D. To hire contractors
Correct Answer: B
Rationale: A demolition permit ensures legal compliance with building codes,
environmental regulations, and safety requirements before demolition begins. It
is required by local authorities.
Question 8
Which material is most likely to contain asbestos in older buildings?
A. Aluminum siding
B. Vinyl flooring, insulation, and pipe lagging
C. Plastic furniture
D. Glass windows
Correct Answer: B
Rationale: Asbestos was commonly used in insulation, vinyl flooring, pipe
lagging, and fireproofing materials in older construction. It is hazardous when
disturbed and requires specialized removal procedures.
