NFPA CFI-I Certified Fire Inspector I Exam Practice Test

Answer : B

The travel distance to fire extinguishers for different hazard classifications is governed by NFPA 10, Standard for Portable Fire Extinguishers.

For ordinary (moderate) hazards, such as those involving moderate quantities of flammable liquids or combustibles, the maximum travel distance to a fire extinguisher with a 20-B rating is 50 feet (15.25 meters).

The B rating refers to extinguishers effective against Class B fires, which involve flammable liquids (e.g., oils, gasoline, solvents).

The 50-foot requirement ensures that fire extinguishers are accessible within a reasonable distance to promptly respond to a fire.

30 feet (A) applies to higher hazard levels like kitchens or specific severe risks.

75 feet (C) is more typical for Class A hazards.

100 feet (D) would not meet NFPA 10 standards for moderate hazards involving flammable liquids.

NFPA 10, Section 6.2.1.1: Travel distance requirements based on hazard classification.

Answer : D

An inspector's right to enter a private dwelling is governed by legal and fire code principles:

Consent of the occupant (I): The occupant may grant permission for the inspection voluntarily.

Warrant authorizing entry (II): If consent is not provided, a legal warrant may be obtained for inspection purposes.

Written complaint (III): A credible written complaint may justify inspection to investigate a fire code violation.

Emergency exists (IV): In emergencies (e.g., imminent danger to life or property), an inspector may enter without consent or a warrant.

All four conditions are valid, making the correct answer D.

NFPA 1, Section 1.7.7: Right of entry for fire inspections.

Legal standards for administrative searches and emergencies.

Answer : C

The right of entry for inspections is governed by NFPA 1, Fire Code:

The Authority Having Jurisdiction (AHJ) is granted the right to enter and inspect premises at reasonable times to ensure compliance with the conditions of the permit and fire safety regulations.

The term ''reasonable times'' ensures that inspections are conducted without causing unnecessary disruption to occupants or operations.

''With the permission of the owner'' (A) is not required under the fire code since permits inherently authorize inspection.

Quarterly cycle (B) is not defined in the fire code and depends on the nature of the permit.

At any time (D) would be unreasonable unless immediate danger is suspected.

NFPA 1, Section 1.7.7: Right of entry for fire inspections.

Answer : C

Egress capacity requirements are detailed in NFPA 101, Life Safety Code, Section 7.3.3.1. For stairs in high-hazard content areas, the capacity is based on:

0.4 in. (10 mm) per person (C): This measurement ensures adequate space for occupants to evacuate safely, considering the increased risk associated with high-hazard contents.

Lower values, such as 0.2 in. (A) or 0.3 in. (B), are insufficient for high-hazard areas.

0.7 in. (D): This exceeds the required value for stairs in high-hazard occupancies.

NFPA 101, Section 7.3.3.1: Egress capacity requirements based on occupancy and hazard levels.

Answer : A

Comprehensive and Detailed Step-by-Step Explanation:

Sprinkler System Design and Installation:

NFPA 13 (Standard for the Installation of Sprinkler Systems) provides detailed guidance on the design, installation, and requirements for water storage tanks, including minimum water temperature to prevent freezing in cold climates.

Other Options Explained:

Option B (NFPA 25): Focuses on inspection, testing, and maintenance of systems, not design parameters.

Option C (NFPA 72): Covers fire alarm systems, not sprinkler systems.

Option D (NFPA 101): Addresses life safety issues, not sprinkler system specifics.

Summary:

Use NFPA 13 to determine the minimum required water temperature for sprinkler system storage tanks.

Answer : B

Visual inspections for fire alarm system components are outlined in NFPA 72, National Fire Alarm and Signaling Code, Table 14.3.1.

Monthly (B): Manual fire alarm boxes must be visually inspected monthly to ensure they are free from obstructions and visible to occupants.

Weekly (A): Weekly inspections are not required for manual pull stations.

Semiannually (C) and Annually (D): These intervals apply to other maintenance tasks, such as functional testing, not visual inspections.

NFPA 72, Table 14.3.1: Inspection intervals for manual fire alarm boxes.

Answer : C

When a significant deviation from the approved plans is discovered during an inspection, the appropriate action is to require a submittal of a set of corrected plans. This is necessary to ensure the system is reviewed and approved in compliance with the applicable codes and standards.

Issue a violation notice (A): While this may be a secondary step if the system does not meet code, it is not the first step when encountering unapproved changes.

Evaluate the installation for compliance (B): Inspectors cannot simply evaluate the installation without updated plans, as the plans serve as the approved baseline for design compliance.

Require corrected plans (C): This step ensures that the new design is documented, reviewed, and approved before proceeding. It maintains compliance with NFPA standards.

Indicate modifications on the approved plan (D): Altering plans without proper review is not acceptable and does not ensure the system meets the original intent.

NFPA 1 and NFPA 13: Systems must comply with approved designs and significant changes require resubmittal for review.
