    Hydrogen Sulfide Safety Train the Trainer

    Course Objective

    • Hydrogen Sulfide is a naturally occurring but lethal gas that is commonly released in the oil and gas industry. The aim of the course is to understand the dangers of Hydrogen Sulfide in natural and industrial areas. This can be done by understanding the properties, the limit values, the side effects associated with each values and concentration, and the adequate controls from administrative controls to personal protective equipment and how they should be enforced in the workplace. The course also allows workers to understand the different types of respiratory protection in the workplace depending on the type of work being done, how long this equipment shall be worn, and when they should be replaced or removed. Workers shall also be assessed on the importance of emergency response and evacuation in the workplace, and how the worker must behave and respond calmly in order to save themselves and others.
    The following points shall be discussed in the course:
    • Properties of H2S. 
    • Locations of H2S. 
    • Identifying limit values. 
    • Understanding side effects of H2S due to the concentration. 
    • Understanding where to go during an H2S drill. 
    • Understanding how to use an SCBA. 
    • Understand the dangers of H2S in a permit to work area and a confined space.
    • Understand the roles and responsibilities of workers while working with H2S in open areas and confined spaces. 
    • Emergency evacuation procedures. 
    • First Aid for H2S drill. 
    • A brief understanding of how respiration occurs naturally. 
    • A brief overview of which type of gases can cause dangerous side effects when inhaled.
    • Identify the different types of breathing apparatuses and when they should be used. 
    • Identify how Breathing Apparatuses should be maintained.
    • Understand what the SCBA is and its parts. 
    • Specify the importance of the SCBA in an area that contains H2S.
    • Specify how to use it and prevent its degradation and when to replace it when needed. 
    • Identify the characteristics of confined spaces 
    • Identify the characteristics of permit-required confined spaces (PRCS) 
    • Discuss definitions relating to confined spaces 
    • Identify the key components of a confined space plan 
    • Identify the duties of the entrant, attendant, and supervisor 
    • Identify the hazards in a confined space 
    • Understand eliminating hazards using Lock-out/Tag-out (LOTO) 
    • Understand ventilation practices

    • All personnel who in the normal course of their duties may be exposed to hazard Hydrogen Sulfide Gas (H2S)
    • The Characteristics of the Confined Space 
    • Hazards associated with Confined Space
    • The importance of using the Lock Out Tag Out System to assist in confined space safety when needed
    • Permit to Work System
    • Roles and Responsibilities associated with Confined Space work
    • Controls associated with the Confined Space System
    • Emergency evacuation and adequate response for each scenario.
    • Supervisors and Team Leaders

    • Hydrogen Sulfide and its properties
    • Dangers and Side Effects of Hydrogen Sulfide Exposure
    • Controls to avoid accidental over-exposure to Hydrogen Sulfide
    • How to evacuate safely during an Emergency Drill
    • Emergency Response and First Aid for injured employees


    • Experience with Hydrogen Sulfide Exposure
    • Experience in Confined Space Exposure
