[F-Gas Category I] 13, Direct Leak Detection and Common Escape Points

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: • How direct leak detection pinpoints escape sites without measuring total system charge mass. • The operational functions and limits of electronic detectors and bubble-testing liquids. • How to identify high-risk leak points including valve stems, corroded pipes, and flared joints. • Why a silent electronic detector is not proof of a leak-free system. • Why flame-based detection creates hazards and should not substitute for suitable approved methods. This independent study resource supports preparation for the City & Guilds 2079 Category I qualification.
