,Q1. A contractor plans to demolish a 4-story unreinforced masonry building in
Philadelphia. The structural engineer's report identifies the building as 'imminently
dangerous' but the owner insists on piecemeal demolition to salvage brick. Under the
Philadelphia Code, which demolition method is REQUIRED?
A. Piecemeal demolition with daily inspections
B. Mechanical demolition using an excavator with a shear attachment
C. Implosion using controlled explosives
D. Demolition by means of a crane and wrecking ball
Correct Answer: B. Mechanical demolition using an excavator with a shear
attachment
Rationale: Philadelphia Code requires mechanical demolition for imminently dangerous
structures to ensure rapid collapse and minimize risk to the public. Piecemeal demolition
is prohibited for dangerous structures. Implosion is not typically required and wrecking
ball use is generally disallowed in dense urban areas due to uncontrolled debris.
Why Wrong:
A - Piecemeal demolition is prohibited for imminently dangerous structures because it
prolongs risk of collapse.
C - Implosion is not mandated and is rarely used for small buildings due to safety and
permitting issues.
D - Wrecking ball demolition is not permitted within the City of Philadelphia due to
lack of precision and safety hazards.

Dangerous Structures
Q2. During a Class B demolition project, an inspector observes that the contractor is
using a demolition method that creates excessive dust and fails to control it. The
inspector issues a stop-work order. Which regulation specifically authorizes the
Department of Licenses and Inspections to halt work for dust violations?
A. Philadelphia Air Management Regulation IX
B. Philadelphia Code § 4-305 (Demolition Permits)
C. OSHA 29 CFR 1926.1101 (Asbestos)
D. Philadelphia Code § 10-100 (Nuisance Abatement)
Correct Answer: A. Philadelphia Air Management Regulation IX
Rationale: Philadelphia Air Management Regulation IX mandates dust control measures
during demolition and authorizes enforcement actions, including stop-work orders, for
violations. The other options address permitting, asbestos, or general nuisance, but not
specifically dust control during demolition.
Why Wrong:
B - Philadelphia Code § 4-305 sets permit requirements, not specific dust control
Page 3
, enforcement.
C - OSHA 29 CFR 1926.1101 governs asbestos, not general dust.
D - Nuisance abatement is a broader provision, not specific to dust control during
demolition.
Reference: Philadelphia Air Management Regulation IX, Dust Control
Q3. A Class B contractor is demolishing a structure that has a fire suppression
system. Which sequence of actions is REQUIRED before demolition begins?
A. Drain the system, cap all pipes, and disconnect the water supply.
B. Notify the Fire Department, obtain a permit to disconnect, and cap the system.
C. Remove all sprinkler heads and leave piping in place for salvage.
D. Pressurize the system to test for leaks before demolition.
Correct Answer: B. Notify the Fire Department, obtain a permit to disconnect, and
cap the system.
Rationale: Philadelphia Fire Code requires notification to the Fire Department and a
permit to disconnect a fire suppression system. The system must be capped to prevent
accidental discharge. Draining without notification or capping is unsafe and illegal.
Pressurizing would be dangerous.
Why Wrong:
A - Draining without notification and capping is insufficient; the Fire Department
must be notified and a permit obtained.
C - Removing sprinkler heads without capping the system is hazardous and violates
code.
D - Pressurizing the system during demolition is unsafe and not a required step.
Reference: Philadelphia Fire Code, Section 901.7, Disconnection of Fire Protection
Systems
Q4. A demolition contractor in Philadelphia discovers that a building to be
demolished contains a 1,000-gallon underground fuel oil tank that is not listed on the
pre-demolition survey. What is the contractor's immediate legal obligation?
A. Excavate the tank and dispose of it as solid waste.
B. Stop work in the area, notify the property owner, and report to the Pennsylvania
Department of Environmental Protection (DEP) within 2 hours.
C. Puncture the tank, drain the contents, and backfill the hole.
D. Ignore the tank as it is not part of the above-ground structure.
Correct Answer: B. Stop work in the area, notify the property owner, and report to
the Pennsylvania Department of Environmental Protection (DEP) within 2 hours.
Rationale: Pennsylvania regulations require immediate notification to DEP for any
discovered underground storage tank (UST) during demolition. The contractor must stop
