To determine the occupant load of a 50,000 gross square foot airport terminal concourse, we use the occupant load factor from 2021 IBC Table 1004.5.

Step 1: Identify the Occupant Load Factor for an Airport Concourse

According to IBC Table 1004.5, the occupant load factor for an airport terminal concourse is 20 sq. ft. per person (gross).

Step 2: Calculate the Occupant Load

50,00020=2,500 occupants\frac{50,000}{20} = 2,500 \text{ occupants}2050,000​=2,500 occupants

Reference to Fire Inspector Documentation:

1. 2021 International Building Code (IBC) – Table 1004.5 (Occupant Load Factor for Airport Concourses)

20 sq. ft. per person is assigned for airport concourses.

2. 2021 International Fire Code (IFC) – Section 1004.1.2 (Occupant Load Determination)

Gross area calculations must follow the correct occupant load factor per IBC Table 1004.5.

Detailed Explanation of Answer Choices:

Option A (Incorrect): 200 is too low based on proper calculations.

Option B (Incorrect): 500 is also too low.

Option C (Incorrect): 1,000 is below the required calculation.

Option D (Correct): 2,500 is the correct calculation based on IBC Table 1004.5.

Thus, the correct and verified answer is: D. 2,500.

The occupant load for an R-2 building's common patio area must be calculated using an occupant load factor. The correct factor is 15 gross sq. ft. per person.

1. 2021 International Building Code (IBC) – Table 1004.5 (Occupant Load Factor)

For outdoor areas (such as patios and terraces), the applicable factor is 15 gross sq. ft. per person.

2. 2021 International Fire Code (IFC) – Section 1004.5 (Outdoor Occupant Loads)

The 15 gross per person requirement is applied to common outdoor gathering areas in residential occupancies (R-2).

Detailed Explanation of Answer Choices:

Option A (Incorrect): 50 net per person applies to storage areas, not patios.

Option B (Incorrect): 11 gross per person is used for business occupancies (B), not residential patios.

Option C (Correct): 15 gross per person is the correct calculation factor for common outdoor spaces in R-2 buildings.

Option D (Incorrect): The code official does not assign occupant load values arbitrarily—they follow IBC Table 1004.5.

Thus, the correct and verified answer is: C. 15 gross per person.

Exit Sign Letter Height Requirement

According to the International Fire Code (IFC) 2021, Section 1013.5, and the International Building Code (IBC) 2021, Section 1013.5, exit sign letters must be at least 6 inches in height. However, the minimum height requirement for the wording within the sign (e.g., "EXIT") is specifically 4 inches.

The stroke width of these letters must be at least 0.5 inches to ensure visibility.

2. Verification of Other Options

Option A (three inches) – Below the minimum height requirement. Incorrect.

Option C (five inches) – Exceeds the minimum standard but is not the correct minimum required size. Incorrect.

Option D (six inches) – This applies to the total EXIT sign height, but the actual letter requirement is 4 inches. Incorrect.

NFPA 101: Life Safety Code (Exit Sign Requirements)

ï‚· Reference to Fire Extinguisher Requirements in Buildings Under Construction:

NFPA 241 (Standard for Safeguarding Construction, Alteration, and Demolition Operations) Section 13.6.1 and IFC 3309.1 require that:

A minimum of one fire extinguisher per floor is required.

Additional extinguishers are required based on stairwells and floor area.

If a building under construction has two stairways, a minimum of two fire extinguishers must be provided per floor to ensure adequate fire protection coverage.

ï‚· Fire Safety Considerations for Construction Sites:

Construction sites pose a high fire risk due to temporary electrical systems, combustible materials, and lack of finished fire suppression systems.

Fire extinguishers must be readily available and evenly distributed near exit stairways and pathways for rapid access in case of an emergency.

ï‚· Clarification of Incorrect Answer Choices:

A. 1 → Incorrect

One extinguisher is the minimum required for floors with only one exit/stairway, but a building with two stairways requires at least two extinguishers.

C. 3 → Incorrect

While more extinguishers can be added for larger areas or high-risk work zones, the minimum requirement remains two for two stairwells.

D. 4 → Incorrect

There is no general requirement for four extinguishers per floor unless dictated by floor size and hazard level.

ï‚· Conclusion:

The correct and verified answer is B (2 fire extinguishers per floor) based on NFPA 241 and IFC 3309.1, ensuring compliance with fire safety standards for buildings under construction.

Foamed plastics or materials containing foamed plastics used for stage scenery must meet strict fire performance requirements to prevent rapid flame spread and fire hazards in assembly occupancies.

The correct fire test standard for these materials is UL 1975 – Standard for Fire Tests for Foamed Plastics Used for Decorative Purposes.

Reference to Fire Inspector Documentation:

1. 2021 International Fire Code (IFC) – Section 807.4.2 (Foamed Plastics for Stage Scenery)

IFC 807.4.2 states that foamed plastics used in scenery must be tested and approved per UL 1975 to ensure fire safety.

2. UL 1975 – Standard for Fire Tests for Foamed Plastics Used for Decorative Purposes

This standard evaluates the flammability and smoke production of foamed plastics used in decorative applications, including stage scenery.

Detailed Explanation of Answer Choices:

Option A (Correct): UL 1975 is the required test standard for foamed plastics used in stage scenery, ensuring compliance with IFC 807.4.2.

Option B (Incorrect): NFPA 11A deals with foam-water fire suppression systems, not foamed plastics for decorative use.

Option C (Incorrect): CPSC 16CFR relates to consumer product safety regulations but does not address fire safety for foamed plastics on stage scenery.

Option D (Incorrect): ASTM D 1784 is a test for rigid PVC plastics and does not apply to foamed plastics used for stage scenery.

Thus, the correct and verified answer is: A. UL 1975.

Retention of Fire Inspection Records

The International Fire Code (IFC) and NFPA 1 specify that records related to fire inspections, violations, and compliance must be maintained for the lifetime of the building.

This ensures a continuous history of inspections, violations, and fire prevention measures, which is critical for enforcement, legal action, and future compliance reviews.

2. Verification of Other Options

Option B (A maximum of five years) – This is incorrect because fire records must be retained longer than five years to ensure historical tracking of fire hazards and compliance over the lifespan of a structure.

Option C (Until the building is renovated or has a change of occupancy) – Renovation or occupancy change does not eliminate past fire risks, so previous records must still be maintained. Incorrect.

Option D (At least one year or until the next fire inspection, whichever is later) – This timeframe is too short and does not comply with NFPA 1 and IFC record-keeping requirements. Incorrect.
