scope:

This standard sets forth accepted practices for hydrogen sulfide (H₂S) safety training and instruction of affected personnel to include, but not be limited to, the following:

• minimum informational content of the course

• recommended exercises and drills

• refresher training requirements

• H₂S Safety Instructor qualifications

• properties and characteristics of H₂S

• sources of H₂S and areas of potential exposure

• typical site-specific safe work practices associated with H₂S operations

• detection methods for H₂S

• selection, use and care of personal protective equipment appropriate for atmospheres containing H₂S concentrations above the Threshold Limit Value-Time Weighted Average (TLV-TWA)

• rescue techniques and first aid procedures for victims of H₂S exposure

Purpose.

The purpose of this standard is to establish minimum requirements for site-specific H2S safety training programs that will enhance safety in occupational settings where hydrogen sulfide is present, or is recognized as being potentially present, above the TLV-TWA.
