Guided Word Hazard Analysis

Abstract

Hazard and operability (HAZOP) and failure mode and effect analysis (FMEA) are very popular in guided word hazard analysis. Both systems require cross-member team formation and technical information to carry out fruitful analysis of the system defined within a system boundary. HAZOP is very much suitable for continuous and batch process hazard analysis through brainstorming with the help of guided words in conjunction with various parameters of the process. Control hazard and operability (CHAZOP) adapted for electrical/electronics/programmable electronics is somewhat different from normal HAZOP and this has been dealt with separately. There have been attempts to automate HAZOP, which need special attention, ...
