This training module saves lives! H2S safety training covers Hydrogen Sulfide (sour gas), which is flammable, colorless and toxic at extremely low concentrations. Heavier than air, it may accumulate in low-lying areas where at lower concentrations its rotten egg odor is easily identifiable. At higher concentrations, the odor may seem sickeningly sweet. Although many areas where the gas is found have been identified, pockets of it can occur anywhere.

Prolonged exposure may cause nausea, tearing of the eyes, headaches or loss of sleep. Some people report asthma as a symptom. At greater exposure, fatigue, headache, dizziness and other symptoms may occur. As the exposure increases, coughing, eye, nose and throat irritation becomes more pronounced, and drowsiness sets in, with symptoms often increasing over several hours. Higher and/or prolonged exposure has proven to be fatal.

PEC H2S Clear (4-hour End User)

PEC Safety has developed a 4-hour standalone course titled "PEC H2S Clear (4-hour End User)." This training course will improve the safety performance of general industry workers who may come in contact with hydrogen sulfide during their regular work duties.

Workers taking the course will be given crucial knowledge of the dangers of Hydrogen Sulfide as well as the precautions, tools and controls they must employ when working in H2S environments.

There are no prerequisites, and the course fulfills current classroom requirements of ANSI Z390. PEC H2S Clear can also be used to enhance our other training courses such as PEC Basic Orientation, PEC Basic/10, or PEC Core Compliance.

With our expertise and our staff of certified instructors, Highline Safety makes it easy for your company to obtain PEC H2S Clear.

H2S in the Work Environment

It is important to know that iron sulfide is a byproduct of many production operations and may spontaneously combust with air. Moreover, flaring operations associated with H2S production will generate Sulfur Dioxide (S02), another toxic gas. Active monitoring for hydrogen sulfide gas, combined with careful planning and employee training programs are the best ways to prevent injury and death in the field. Where concentrations of Hydrogen Sulfide may exceed 10 Parts Per Million (PPM), personnel should be provided with training before beginning work assignments.

Contingency Planning

Whenever work takes place in a potential H2S environment, a contingency plan should be implemented. This plan should include appropriate instruction in the use of hydrogen sulfide safety equipment for all workers present at the site. Gas detection procedures should be implemented wherever hydrogen sulfide may exist, and appropriate respiratory protection for normal and emergency use must be available. Comprehensive training should be provided for all workers in H2S operations.
