Revised Standard Addresses Hydrogen Sulfide Training Programs

A recently revised standard sets forth accepted practices for hydrogen sulfide (H₂S) safety training and instruction of affected personnel. ANSI/ASSE Z390.1-2017, , is intended to help organizations with potential H₂S exposure put training in place to protect workers.

The standard covers topics such as recommended exercises and drills, properties and characteristics of H₂S, sources of H₂S and areas of potential exposure, detection methods for H₂S, and engineering controls. Also included in the standard are sections on the properties, characteristics, and safe work practices for sulfur dioxide (SO₂); the selection, use, and care of personal protective equipment appropriate for atmospheres containing H₂S concentrations above occupational exposure limits; and rescue techniques and first aid procedures for victims of H₂S exposure. A sample certification course outline can be found in the standard’s appendices.
