Question 1Fire Code Administration and Enforcement
Under the International Fire Code, who is generally responsible for obtaining the permits required for regulated work such as installing a fire sprinkler system?
- The insurance carrier for the building
- The manufacturer of the sprinkler equipment
- The property owner or the owner's authorized agent Correct answer.
- The local fire code official
Explanation
The code places the duty to obtain required permits on the owner or the owner's authorized agent, such as a licensed contractor acting for the owner. The fire code official reviews and issues permits but does not apply for them on the owner's behalf.
Question 2Fire Code Administration and Enforcement
A building owner wants to change the occupancy classification of an existing structure. What must generally happen before the change is approved under the fire code?
- The owner must demolish all noncompliant features before any review begins
- The fire code official must determine that the new occupancy will comply with code requirements for that use Correct answer.
- The owner must submit a new construction permit application for a completely new building
- The change is automatic once the zoning department approves the use
Explanation
A change of occupancy requires review to confirm that the building will meet the fire and life safety requirements applicable to the new use. The fire code official evaluates compliance, and additional safeguards may be required before approval.
Question 3Fire Code Administration and Enforcement
Which document typically authorizes the fire code official to enter a premises to inspect for fire code compliance?
- A certificate of occupancy issued by the zoning board
- The fire code's inspection and enforcement authority, exercised in accordance with law Correct answer.
- A subpoena issued by the building owner
- A warranty of habitability
Explanation
Fire codes grant the code official authority to inspect premises to enforce the code, subject to legal limits such as consent or a warrant where required. This authority is the basis for routine and complaint-driven inspections.
Question 4Fire Code Administration and Enforcement
When a fire code official finds a condition that constitutes an immediate danger to life, what action is the code most likely to authorize?
- Waiting for the next scheduled annual inspection
- Ordering immediate evacuation or other prompt abatement action Correct answer.
- Referring the matter solely to the property insurer
- Issuing a routine notice with a 90-day correction period
Explanation
Immediate hazards allow the code official to take prompt action, which may include ordering evacuation, closing the premises, or abating the hazard without delay. Ordinary correction periods are not appropriate when life safety is immediately at risk.
Question 5Fire Code Administration and Enforcement
What is the primary purpose of a certificate of occupancy in fire code administration?
- To record the property tax assessed on the structure
- To document that a building complies with applicable codes for its intended use Correct answer.
- To certify the structural engineer's professional license
- To authorize the sale of the property to a new owner
Explanation
A certificate of occupancy confirms that the building or portion thereof may lawfully be used because it meets applicable code requirements for that occupancy. It ties the approved use to the conditions verified during permitting and inspection.
Question 6Fire Code Administration and Enforcement
A fire code official issues a notice of violation. What is the typical next step for the responsible party?
- Pay a fine and continue operating without making corrections
- Transfer responsibility to the fire department
- Correct the violation within the time specified or appeal through the established process Correct answer.
- Ignore the notice because it is advisory only
Explanation
A notice of violation identifies the deficiency and a compliance timeline, and the responsible party must correct it or pursue any appeal available under the code. Failure to comply can lead to further enforcement, including penalties or closure.
Question 7Fire Code Administration and Enforcement
Which of the following best describes the role of a board of appeals in fire code administration?
- It hears challenges to decisions of the code official and may grant relief under code criteria Correct answer.
- It performs routine inspections in place of the fire code official
- It conducts fire investigations and issues criminal charges
- It writes the model fire code for the jurisdiction
Explanation
Boards of appeals provide an administrative review process for persons aggrieved by decisions of the code official, applying the criteria in the code. They do not replace the official's inspection or enforcement duties.
Question 8Fire Code Administration and Enforcement
A code official is considering granting a variance or alternative method of compliance. What must generally support such a decision?
- A vote of the building's tenants
- Approval by the property's insurance company
- A finding that the alternative provides equivalent or greater protection and meets code conditions Correct answer.
- A request from the building owner alone
Explanation
Alternatives and variances are approved only when the official finds the proposed approach provides equivalent safety and satisfies the code's stated conditions. The decision must be based on technical merit, not simply on the owner's preference.
Question 9Fire Code Administration and Enforcement
What is the purpose of requiring construction documents to be submitted for review before regulated work begins?
- To allow the contractor to begin work immediately upon submission
- To transfer liability for design errors to the fire department
- To satisfy insurance paperwork requirements
- To verify that the proposed work will comply with the code before it is built Correct answer.
Explanation
Plan review lets the code official confirm that proposed work meets code requirements before construction, reducing the need for costly corrections later. Approval of documents is a prerequisite to permitted work, not a liability transfer.
Question 10Fire Code Administration and Enforcement
During construction, the fire code official may require inspections at specified stages. What is the main reason for staged inspections?
- To increase permit fee revenue for the jurisdiction
- To delay the project schedule for administrative convenience
- To confirm that concealed work and key features comply before they are covered or placed in service Correct answer.
- To replace the contractor's own quality control program
Explanation
Staged inspections verify compliance at points where later observation would be impossible, such as before walls are closed. They complement, rather than replace, the contractor's quality control.
Question 11Fire Code Administration and Enforcement
A fire code official discovers that permitted work is being done in a manner that creates a hazard. What enforcement option is generally available?
- Immediate criminal prosecution of the building owner
- Only a verbal warning with no follow-up
- Issuance of a stop-work order for the affected work Correct answer.
- Automatic revocation of the contractor's state license
Explanation
The code official may issue a stop-work order when work is proceeding in violation or creates a hazard, halting the affected activity until compliance is achieved. License revocation and criminal prosecution fall to other authorities and processes.
Question 12Fire Code Administration and Enforcement
Which activity typically requires a permit under the fire code?
- Rearranging office furniture within a room
- Routine housekeeping in an office
- Installing or modifying a fire alarm system Correct answer.
- Replacing a light bulb in an existing fixture
Explanation
Fire codes require permits for work involving regulated fire protection systems, including installation or modification of fire alarm systems. Simple maintenance and housekeeping activities generally do not require permits.
Question 13Fire Code Administration and Enforcement
What does the term 'authority having jurisdiction' generally refer to in fire code enforcement?
- The insurance underwriter evaluating risk
- The organization or official responsible for approving and enforcing code compliance Correct answer.
- The building owner's designated representative
- The manufacturer certifying equipment
Explanation
The authority having jurisdiction is the entity responsible for approving equipment, materials, installations, and enforcing code requirements. It is typically the local fire code official or fire department.
Question 14Fire Code Administration and Enforcement
A building owner disagrees with a fire code official's interpretation of a requirement. What is the appropriate first step under typical code administration?
- Sue the fire department in federal court immediately
- Ask the contractor to decide the issue
- File an appeal with the board of appeals or follow the code's review process Correct answer.
- Ignore the interpretation and proceed with the original plan
Explanation
Codes provide an administrative appeal or review process for disputes over official decisions. Exhausting that process is the appropriate path before seeking other remedies.
Question 15Fire Code Administration and Enforcement
Which records are fire code officials typically required to maintain regarding permits and inspections?
- Records of permit applications, issued permits, and inspection results Correct answer.
- Only records of violations that result in fines
- No records, since enforcement is informal
- Only records requested by the property owner
Explanation
Code administration relies on documentation of applications, permits, and inspections to track compliance and support enforcement. These records are maintained by the enforcing agency as part of its official duties.
Question 16Fire Code Administration and Enforcement
A tenant operates a business in a building and creates a fire code violation through their operations. Who may the fire code official cite for the violation?
- The fire code official's supervisor
- The party responsible for the condition, which may include the tenant or operator Correct answer.
- Only the fire alarm contractor
- Only the building owner, regardless of who caused the condition
Explanation
Enforcement may be directed at the person responsible for the violation, which can be an owner, tenant, or operator depending on who caused or controls the condition. Responsibility follows the conduct or control, not solely ownership.
Question 17Fire Code Administration and Enforcement
What is the effect of failing to obtain a required permit before performing regulated work?
- The fire code official must approve the work without review
- The owner automatically receives a certificate of occupancy
- The work may be subject to enforcement, including required correction and additional fees or penalties Correct answer.
- The work is deemed approved because it was completed
Explanation
Unpermitted work is a code violation that can trigger enforcement, including orders to correct or remove work and assessment of penalties or investigative fees. Completion of work does not substitute for required approvals.
Question 18Fire Code Administration and Enforcement
Which statement best describes how a jurisdiction adopts a model fire code?
- The code organization enforces it in each city
- The state insurance department enforces it directly
- The jurisdiction formally adopts the model code by ordinance or law, often with local amendments Correct answer.
- The model code applies automatically without any local action
Explanation
Model codes become enforceable only when a jurisdiction adopts them through its legal process, frequently with amendments tailored to local conditions. The code organization that publishes the model code does not enforce it.
Question 19Fire Code Administration and Enforcement
A fire code official finds a locked exit door during an inspection of an occupied assembly space. What is the most appropriate immediate enforcement response?
- Schedule a follow-up inspection in six months
- Note the condition for the next annual permit renewal
- Require immediate correction because the condition endangers occupants Correct answer.
- Refer the matter to the property insurer for review
Explanation
A blocked or locked exit in an occupied assembly space is an immediate life-safety hazard requiring prompt correction. Deferring action would leave occupants at risk during egress.
Question 20Fire Code Administration and Enforcement
What generally happens to a permit if the work authorized by the permit is not commenced within the time specified by the code?
- The permit transfers to any other property owned by the applicant
- The permit may expire and become invalid Correct answer.
- The permit converts into a certificate of occupancy
- The permit automatically extends for another full term
Explanation
Permits are time-limited; if work does not begin within the specified period, the permit can expire and a new permit may be required. This prevents stale approvals from being used for work planned under outdated conditions.
Question 21Fire Code Administration and Enforcement
How does the fire code generally treat existing buildings that complied with the code in effect at the time of construction but do not meet current requirements?
- They are entirely exempt from all fire code provisions
- They must immediately comply with every new requirement
- They are addressed through code provisions for existing structures, with new requirements applied to new work and specific triggers Correct answer.
- They must be demolished within one year
Explanation
Codes distinguish between new construction and existing buildings, generally applying new requirements to new work, alterations, and specific triggering conditions rather than requiring wholesale retrofits. This balances safety improvements with practicality.
Question 22Fire Code Administration and Enforcement
What is the primary function of a fire code official during a complaint-based inspection?
- To collect evidence for a civil lawsuit between private parties
- To mediate disputes between neighboring property owners
- To determine whether the alleged condition violates the code and to enforce as needed Correct answer.
- To provide free repair services to the property owner
Explanation
Complaint-based inspections focus on whether the reported condition violates the code and, if so, on securing compliance. The official's role is regulatory enforcement, not private dispute resolution.
Question 23Fire Code Administration and Enforcement
A property owner proposes an alternative fire protection approach not explicitly described in the code. Under what condition may the code official approve it?
- If the official determines it provides equivalent safety and meets the code's approval criteria Correct answer.
- If the alternative is less expensive than the prescribed method
- If the contractor has used it on other projects
- If the owner signs a waiver of all liability
Explanation
Alternative methods are approved based on a finding of equivalent or superior protection under the code's criteria. Cost savings or prior use alone do not justify approval.
Question 24Fire Code Administration and Enforcement
Which of the following is a typical consequence when a property owner fails to comply with a fire code order after the correction period expires?
- The order is automatically withdrawn
- The fire code official may pursue further enforcement, including penalties or closure of the premises Correct answer.
- The violation becomes legal through the passage of time
- The property is immediately transferred to the jurisdiction
Explanation
Failure to comply within the specified period allows the code official to escalate enforcement, which may include penalties, legal action, or closing the premises. Noncompliance does not extinguish the violation.
Question 25Fire Code Administration and Enforcement
Why do fire codes commonly require that a permit be posted or kept available at the work site?
- To advertise the contractor's business to the public
- To replace the need for any inspections
- To allow the official to verify that the work is authorized and matches the approved scope Correct answer.
- To satisfy the manufacturer's warranty conditions
Explanation
Posting or retaining the permit on site lets inspectors confirm that the work is authorized and within the approved scope. It supports, rather than replaces, the inspection process.
Question 26Fire Code Administration and Enforcement
Which body or individual is ordinarily responsible for adopting the fire code that a local fire official enforces?
- The state fire marshal's field inspectors
- The governing legislative body of the jurisdiction Correct answer.
- The property insurer of each regulated building
- The local fire chief acting alone
Explanation
A model fire code has no legal effect until it is adopted by the governmental body with authority to legislate for the jurisdiction, such as a city council or county board. The fire official then administers and enforces the adopted text. Neither individual officials nor private insurers create the enforceable code.
Question 27Fire Code Administration and Enforcement
A fire inspector enters a commercial kitchen and finds a suppression system that has never been inspected by a qualified person. Under most fire codes, what is the appropriate first action?
- Issue a written notice directing the owner to have the system inspected and serviced Correct answer.
- Immediately file criminal charges against the owner
- Order the building demolished
- Refer the matter directly to the board of appeals
Explanation
Fire codes generally direct the official to secure compliance through written notice and a reasonable time to correct the deficiency. Criminal prosecution and demolition are extraordinary remedies reserved for serious, unresolved conditions. The appeals board hears challenges to orders rather than initiating enforcement.
Question 28Fire Code Administration and Enforcement
What is the principal purpose of a fire code's certificate of occupancy requirement for a new building?
- To document that the building may lawfully be used for its intended purpose Correct answer.
- To transfer ownership of the building to the occupant
- To set the property tax rate for the structure
- To guarantee the building will never have a fire
Explanation
A certificate of occupancy records that the completed structure has been inspected and may be used for the occupancy classification approved. It links the approved use and construction to lawful occupancy. It has no role in taxation, ownership transfer, or guaranteeing future performance.
Question 29Fire Code Administration and Enforcement
A fire official must enter a locked, unoccupied warehouse to investigate a reported hazardous storage condition. The owner refuses entry. What is the usual legal basis for the official's authority to inspect?
- The absence of any posted no-trespassing sign
- The official's personal discretion to enter any building at any time
- Statutory right of entry provisions in the fire code or enabling law, exercised with any required warrant Correct answer.
- A verbal request from a neighboring business owner
Explanation
Fire codes and enabling statutes typically grant officials a right of entry for inspection purposes, often conditioned on presenting credentials and, where entry is refused, obtaining an administrative search warrant. Unilateral discretion and neighbor complaints do not create entry authority. A lack of signage does not confer a right to enter.
Question 30Fire Code Administration and Enforcement
An owner applies for a permit to install a new commercial cooking hood system. Which document is most likely required to be submitted with the application?
- A list of the owner's other properties
- A copy of the previous owner's deed
- Construction drawings and specifications for the proposed work Correct answer.
- The owner's personal income tax return
Explanation
Permit applications for regulated work generally must be accompanied by plans and specifications sufficient to show the scope and code compliance of the proposed installation. Financial and property records unrelated to the work are not part of the submittal. This lets the official review the design before approving the permit.
Question 31Fire Code Administration and Enforcement
A contractor completes work under a fire permit and the official determines it complies with the code. What is the typical administrative result?
- The permit automatically transfers to the next owner
- The permit converts into a variance
- The permit is voided and must be reapplied for
- The permit is closed or finalized and the approval is recorded Correct answer.
Explanation
When inspection confirms that permitted work complies, the official records the approval and closes the permit file. Permits are generally not transferable to another party without authorization, and they do not become variances. A completed compliant project is not voided.
Question 32Fire Code Administration and Enforcement
During a routine inspection, a fire official observes conditions that violate the code but that were not part of the original complaint. What is the appropriate response?
- Document the additional violations and process them through normal enforcement Correct answer.
- Ignore them because they were outside the scope of the visit
- Correct the conditions personally without notifying the owner
- Wait for a separate complaint before taking any action
Explanation
Officials are expected to address any code violations they observe in the course of an inspection, not only the matter that prompted the visit. The proper approach is to document the conditions and follow standard notice and enforcement procedures. Officials do not silently ignore observed hazards or alter private property without authorization.
Question 33Fire Code Administration and Enforcement
What is the standard of proof generally applied when a fire official must show that a condition constitutes a violation before issuing an order?
- The official must be able to articulate facts showing the condition fails to meet a specific code requirement Correct answer.
- The official must prove the violation beyond a reasonable doubt
- The official may act on rumor without any supporting facts
- The official must obtain a criminal conviction before ordering correction
Explanation
Enforcement orders must be grounded in observable or documented facts tied to a specific code provision, and the official should be able to articulate that basis. The beyond-a-reasonable-doubt standard applies to criminal cases, not administrative code enforcement. Unsupported rumor or a prior conviction is not required.
Question 34Fire Code Administration and Enforcement
A jurisdiction wants to enforce a newer edition of the model fire code than the one currently in effect. What must occur before the newer edition can be enforced?
- The governing body must formally adopt the newer edition Correct answer.
- Insurers may require it and thereby make it enforceable
- The newest edition applies automatically once published
- The fire chief may begin enforcing it by memorandum
Explanation
A model code edition becomes enforceable only through formal adoption by the jurisdiction's legislative body. Publication alone does not make a new edition law, and neither a memorandum from the chief nor an insurer's requirement can substitute for adoption. Until adoption, the previously adopted edition governs.
Question 35Fire Code Administration and Enforcement
A fire official issues an order that a business owner believes exceeds the official's authority. Before seeking review by the board of appeals, what must the owner generally do?
- Sell the property to avoid the order
- Refuse to comply indefinitely
- File a written appeal within the time limit stated in the code Correct answer.
- Publicly post a notice disputing the order
Explanation
Appeals of enforcement orders are typically governed by procedural requirements, including filing a written appeal within a specified period. Ignoring the order or attempting to evade it through transfer does not preserve review rights. The appeal process exists to resolve disputes over authority and interpretation.
Question 36Fire Code Administration and Enforcement
What is the primary purpose of requiring periodic fire safety inspections of certain occupancies such as assembly and high-hazard uses?
- To generate revenue for the fire department
- To verify continued compliance as conditions and uses change over time Correct answer.
- To replace the need for fire suppression systems
- To assign liability for future fires
Explanation
Periodic inspections confirm that a building continues to meet code requirements after initial approval, since uses, contents, and maintenance change over time. They are not a revenue mechanism and do not substitute for installed fire protection. Liability for a future fire is determined by other legal processes.
Question 37Fire Code Administration and Enforcement
A fire official finds an unpermitted structural alteration that has reduced the required exit width in an occupied building. Which enforcement approach best reflects the code's intent?
- Issue only a warning with no follow-up
- Order the condition abated, which may include restoring the exit width or stopping the unauthorized use Correct answer.
- Require the owner to install additional signage instead of correcting the exit width
- Allow the condition because the alteration is already complete
Explanation
When unpermitted work creates a hazard, the code's intent is abatement of the hazardous condition, which may require restoring compliance or halting the noncompliant use. Completion of the work does not cure the violation. Signage cannot substitute for required egress width. A warning without follow-up does not achieve abatement.
Question 38Fire Code Administration and Enforcement
A fire official's order requires a specific corrective action, and the owner proposes a different method that achieves equivalent safety. How should the official generally evaluate the proposal?
- Reject it automatically because it differs from the prescribed method
- Approve it only if the owner waives all future inspections
- Determine whether the alternative provides equivalent protection and approve it if supported by technical evidence Correct answer.
- Defer entirely to the owner's contractor
Explanation
Fire codes commonly allow alternative methods that provide equivalent safety when supported by technical documentation and accepted by the official. Automatic rejection ignores this flexibility, while blanket waivers or uncritical deference to a contractor undermine the official's independent judgment. The official must evaluate the evidence of equivalency.
Question 39Fire Code Administration and Enforcement
What distinguishes a fire code official's authority to issue an emergency order from an ordinary notice of violation?
- An emergency order applies only to vacant buildings
- An emergency order may only be issued after a full hearing
- An emergency order may require immediate action when an imminent hazard threatens life or property Correct answer.
- An emergency order eliminates the need for any documentation
Explanation
Emergency authority allows the official to act swiftly, including ordering immediate corrective action or evacuation, when an imminent hazard exists. Ordinary notices typically allow time to correct. Emergency orders still require documentation and are subject to review, and they are not limited to vacant structures.
Question 40Fire Code Administration and Enforcement
A fire official is asked to approve a permit for work that the applicant began before applying. How should the official generally treat the pre-existing unpermitted work?
- Deny all future permits to the applicant permanently
- Approve the permit without examining the existing work
- Require the applicant to remove the work regardless of its condition
- Require the work to be inspected and brought into compliance as a condition of approval Correct answer.
Explanation
When unpermitted work is discovered, the official typically requires that it be inspected and shown to comply before or as a condition of approval. Approving without review would leave unverified conditions in place. Permanent denial and mandatory removal are disproportionate where the work can be made compliant.
Question 41Fire Prevention and Life Safety Provisions
According to the ICC F2 examination scope, which document is the primary model code governing fire prevention and life safety provisions for existing buildings?
- International Building Code
- International Residential Code
- International Fire Code Correct answer.
- International Existing Building Code
Explanation
The International Fire Code (IFC) is the model code that establishes minimum fire prevention and life safety requirements for existing structures and their operations. The other codes address new construction, rehabilitation, or one- and two-family dwellings rather than general fire prevention.
Question 42Fire Prevention and Life Safety Provisions
Under the IFC, who is generally responsible for ensuring that a building and its systems comply with fire prevention requirements on a day-to-day basis?
- The owner or the owner's designated agent Correct answer.
- The responding fire department
- The local building inspector
- The fire code official alone
Explanation
The IFC places the duty of code compliance on the owner or the owner's designated agent, who must maintain the premises and systems in accordance with the code. The fire code official enforces the code but does not assume operational responsibility for the property.
Question 43Fire Prevention and Life Safety Provisions
A means of egress system consists of which three continuous components, in order of travel?
- Exit, exit access, and exit discharge
- Exit discharge, exit, and exit access
- Exit access, exit discharge, and exit
- Exit access, exit, and exit discharge Correct answer.
Explanation
The means of egress is defined as a continuous and unobstructed path of travel from any point in a building to a public way, consisting of exit access, the exit, and exit discharge. The components must be arranged in that sequence for the path to be continuous.
Question 44Fire Prevention and Life Safety Provisions
What is the maximum travel distance permitted to a single exit in a nonsprinklered Group B occupancy, unless otherwise permitted by the code?
- 300 feet
- 200 feet Correct answer.
- 250 feet
- 150 feet
Explanation
For nonsprinklered business occupancies, the IFC generally limits travel distance to a single exit to 200 feet. This limit increases when the building is protected throughout by an automatic sprinkler system.
Question 45Fire Prevention and Life Safety Provisions
Which of the following best describes an exit enclosure?
- A discharge path leading to the public way
- A fire-resistance-rated separation enclosing the exit Correct answer.
- A corridor that provides access to an exit
- An open stairway within an atrium
Explanation
An exit enclosure is a fire-resistance-rated separation that protects the exit element of the means of egress from the remainder of the building. It keeps the exit path tenable during a fire and prevents smoke and fire from entering.
Question 46Fire Prevention and Life Safety Provisions
In a Group A assembly occupancy, what is the minimum required number of means of egress where the occupant load is 50 or more?
- Three
- Two Correct answer.
- One
- Four
Explanation
Assembly occupancies with an occupant load of 50 or more must have at least two separate and remote means of egress. Fewer occupants may be served by a single means of egress under specific conditions.
Question 47Fire Prevention and Life Safety Provisions
Which component is required to make a fire alarm system capable of alerting occupants throughout a building?
- Smoke detectors
- Notification appliances Correct answer.
- Pull stations
- Sprinkler flow switches
Explanation
Notification appliances such as horns, speakers, and strobes provide the audible and visible signals that alert building occupants. Detection and manual initiation devices trigger the system, but notification appliances perform the alerting function.
Question 48Fire Prevention and Life Safety Provisions
What is the primary purpose of an automatic sprinkler system in a building?
- To notify the fire department automatically
- To provide a source of water for manual firefighting
- To pressurize the standpipe system
- To control or extinguish a fire at its incipient stage Correct answer.
Explanation
Automatic sprinkler systems are designed to discharge water directly onto a fire to control or extinguish it while it is still small. This limits heat release and prevents the fire from growing beyond the capability of manual suppression.
Question 49Fire Prevention and Life Safety Provisions
A building has a required fire-resistance-rated separation between two occupancies. What does the rating primarily limit?
- The number of exits required for each area
- The travel distance within each area
- The spread of fire and smoke between the separated areas Correct answer.
- The occupant load of each area
Explanation
Fire-resistance-rated separations are constructed to resist the passage of fire and smoke for a specified period, protecting adjacent areas from fire spread. Occupant load, travel distance, and exit counts are separate egress considerations.
Question 50Fire Prevention and Life Safety Provisions
What is the minimum required fire-resistance rating for a fire barrier separating a Group H occupancy from an adjacent occupancy, where the code specifies a two-hour rating?
- Two hours Correct answer.
- Three hours
- Four hours
- One hour
Explanation
Where the code specifies a two-hour fire barrier for a separation, the required rating is two hours. Fire barriers must be constructed and supported to maintain the specified rating and resist fire spread for that duration.
