Who Should Take This Course?
Hydrogen Sulfide is extremely hazardous, and training is critical for any employee who may encounter it during their work activities. The type of training required depends on the potential level of exposure:
Low Concentrations: Workers typically need awareness-level H2S training.
At or Above Occupational Exposure Limit (OEL): Workers often require more detailed instruction, such as our 6-Hour Hydrogen Sulfide (H2S) Certification course.
This 4-Hour OSHA/ANSI H2S Awareness course helps meet the training requirements of Federal and State OSHA regulations. It is also designed to meet the Awareness-level training standard of ANSI/ASSP Z390.1 – Accepted Practices for Hydrogen Sulfide Training Programs.
For workers who need basic H2S awareness training but do not require ANSI Z390.1 compliance, we also offer a shorter 2-Hour OSHA Hydrogen Sulfide (H2S) Awareness Online course.
Please note: While this course covers H2S hazards, prevention methods, and emergency response, additional hands-on training is often required. Your employer is responsible for providing site-specific instruction on protective equipment and safety procedures.
