ANSI / ASSP Z390.1 Hydrogen Sulfide Training Standard

Hydrogen sulfide is a major hazard in oil and gas operations, as well as in the chemical industry, municipal sewer systems and laboratories. Exposure to hydrogen sulfide (H₂S) can cause a wide range of health effects.

What Is the Hydrogen Sulfide Training Standard

The ANSI/ASSP Z390.1 standard establishes minimum requirements for site-specific hydrogen sulfide safety training programs that will enhance safety in occupational settings where hydrogen sulfide is present or is recognized as being potentially present.

Why Use the Hydrogen Sulfide Training Standard

This standard establishes accepted practices for hydrogen sulfide safety training and identifies instructor qualifications. Trainers can use the standard to develop course content to ensure that affected employees understand the properties and characteristics of H₂S, its sources and potential areas of exposure; can apply site-specific safe work practices; know how H₂S is detected and what PPE is required; and understand rescue techniques. The standard also helps trainers design and execute practice drills and deliver refresher training.
