Hazard Identification and Risk Analysis

A thorough Hazard Identification and Risk Analysis, or risk, system is the core element in the RBPS pillar of understanding hazards and risk. The chapter describes the meaning of risk for RBPS purposes, the attributes of a risk system, and the steps an organization might take to implement a robust program for identifying hazards and analyzing risk.
