THMG477 – Hydrogen Sulfide | Part II

January 03, 2025

Join us for this two-part series as we dive into the details of hydrogen sulfide and its presence on all our meters. We'll explore why OSHA mandates it, the industry's focus on it, and why it's important for you to be informed.


In this episode's bonus segment, Bob tackles a question from a student studying operations, sparking a community-driven discussion: What time is it, really?

Episode Overview

In the second part of the series on hydrogen sulfide (H2S), the hosts explore the challenges posed by H2S in the oil and gas industry, particularly in pipeline transportation. They discuss the unique risks associated with unscented pipelines, confined spaces, and improper safety measures. This episode also delves into the biological effects of H2S, its flammability, and corrosion hazards. The team wraps up with an interesting audience-submitted question about the distinction between "night and day" in operational contexts.
