NFPA CFI-I Exam Dumps

When performing a fire hydrant flow test, a minimum static pressure drop is required to ensure that the test provides accurate and meaningful results. According to NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants:

A 10 percent pressure drop is the minimum acceptable difference between the static pressure (no flow) and residual pressure (while flowing).

This drop ensures that water flow is sufficient for an accurate test and reflects the system's capacity under actual fire conditions.

5 percent (A): Too low to provide reliable results.

15 percent (C) and 20 percent (D): Higher drops are acceptable but not the minimum requirement.

NFPA 291, Section 4.9: Static pressure drop requirements during flow testing.

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.

Under 16 CFR 1632, the flammability of mattresses and mattress pads is tested by exposing the material to a smoldering cigarette.

The maximum allowable char length is 2 inches (51 mm).

This standard ensures that the material does not ignite or propagate fire.

Larger char lengths indicate excessive flammability and would fail the standard.

16 CFR 1632: Federal flammability standards for mattresses.

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.

Comprehensive and Detailed Step-by-Step Explanation:

Liquid Classification by Flash Point:

Per NFPA 30 (Flammable and Combustible Liquids Code):

Class IC: Flash point below 73F but above 100F.

Class II: Flash point between 100F and 140F.

Class IIIA: Flash point between 140F and 200F.

Class IIIB: Flash point at or above 200F (93C).

Why Class IIIB Applies:

Class IIIB liquids, with higher flash points, are considered less flammable and less likely to ignite under normal conditions.

Other Options Explained:

Option A (Class IC): Flash point below 100F.

Option B (Class II): Flash point below 140F.

Option C (Class IIIA): Flash point below 200F.

Summary:

A Class IIIB liquid has a flash point at or above 200F (93C).
