"This handbook provides information necessary to determine if a chemical process is covered by the PSM Rule and provides an interpretation of the 14 elements of the PSM Rule. An overview of these elements is given in Table 1.1. This handbook also describes DOE programs that may, with or without modification, satisfy the requirements of this Rule. Questions and answers, based on OSHA's responses to questions from industry and labor, are provided at the end of most sections. Applicable question numbers are referenced in the text in brackets. Sample programs are included that may be used to satisfy provisions of the PSM Rule. These sample programs are adapted from industry and are not mandatory, even though some contain directive language (e.g., will, shall, should). Appendix D lists additional sources of detailed PSM information. For specific guidance on the Process Hazards Analysis element , the reader is referred to the handbook, "Chemical Process Hazards Analysis" (DOE-HDBK-1100-96)."
