1. Which Colorado requirement is most important to verify before
beginning demolition of a structure that may contain regulated
asbestos-containing material?
A. The building’s original construction cost
B. The owner’s preferred demolition sequence
C. Required asbestos inspection, notification, and applicable abatement
requirements
D. The contractor’s equipment rental agreement
Rationale: Colorado demolition projects may be subject to asbestos
inspection, notification, and abatement requirements before demolition
proceeds. These requirements are intended to prevent uncontrolled
release of asbestos fibers.
2. Before a demolition contractor begins work on an existing
commercial building in Colorado, which action best establishes
whether hazardous materials are present?
,A. Begin demolition at the roof and inspect materials as they fall
B. Conduct an appropriate pre-demolition hazardous-materials survey
C. Remove all interior finishes without documentation
D. Rely solely on the building owner’s verbal statement
Rationale: A pre-demolition survey helps identify asbestos, lead-based
paint, refrigerants, mercury, PCBs, and other regulated materials so they
can be properly managed before structural demolition begins.
3. During demolition, a wall is found to contain material suspected of
being asbestos-containing material that was not identified during
planning. What should the contractor do first?
A. Continue demolition using water suppression
B. Break the material into smaller pieces
C. Stop affected work and follow applicable asbestos identification and
handling procedures
D. Place the material in ordinary construction debris
Rationale: Suspect asbestos-containing material should not be disturbed
unnecessarily. Work affecting the material should be controlled while
appropriate evaluation and regulatory procedures are followed.
4. Which condition most strongly indicates that a structure should be
evaluated by a qualified professional before demolition begins?
A. The building has painted walls
B. The structure has ordinary wood trim
C. The structure has fire damage, severe deterioration, or compromised
,structural members
D. The building has recently installed lighting
Rationale: Fire damage, deterioration, and compromised structural
members can create unpredictable collapse hazards. A competent
structural evaluation helps determine safe demolition methods and
sequencing.
5. What is the principal purpose of establishing a controlled
demolition exclusion zone?
A. To increase the number of workers in the demolition area
B. To prevent unauthorized persons from entering areas exposed to
demolition hazards
C. To provide additional parking for employees
D. To store hazardous materials indefinitely
Rationale: An exclusion zone separates workers and the public from
falling debris, equipment movement, structural instability, dust, and
other hazards associated with demolition operations.
6. When demolishing a multi-story structure, why is the demolition
sequence particularly important?
A. It determines the color of the debris containers
B. It controls structural stability and helps prevent uncontrolled collapse
C. It eliminates the need for personal protective equipment
D. It determines the contractor’s insurance premium automatically
, Rationale: Demolition must generally proceed according to a planned
sequence that maintains stability until structural components are
intentionally removed. Improper sequencing can cause premature
collapse.
7. Which demolition practice presents the greatest risk of an
uncontrolled structural collapse?
A. Removing selected components according to an engineered sequence
B. Maintaining temporary supports where required
C. Removing critical load-bearing members without evaluating their effect
on the remaining structure
D. Establishing an exclusion zone
Rationale: Removing load-bearing components without considering load
paths can transfer forces unexpectedly and cause portions of the
structure to collapse prematurely.
8. Before demolition equipment operates near overhead electrical
conductors, the contractor should primarily determine:
A. The conductor manufacturer’s warranty period
B. Applicable clearance, de-energization, grounding, and utility
coordination requirements
C. The equipment operator’s preferred working speed
D. The color of the utility poles
