Hazard Analysis and Risk Assessment
Hazard Analysis and Risk Assessment are typically carried out in five steps:
- Define the scope of work and describe the system and its components
- Identify hazards
- Evaluate the impact of the hazards on
- the environment and public
- the facility and institution
- the equipment and personnel
- Resolve hazards, identify required personal protective equipment (PPE), verify engineering and/or administrative controls, and determine if risk has been reduced to an acceptable level
- iterate back to step (1) to ensure no additional hazards have been introduced by controls or changes to the system and its components. See Operating Procedures (for Change Control).
- Follow up actively with periodic review of work scope and hazards
The Hazard Analysis and Risk Assessment process should include members of the project and/or safety teams that have expertise in the various aspects of the project (e.g., project management, chemical systems, electrical systems, waste management, etc.). The process should continue throughout the operational lifetime of a system. New hazards may be identified for an aging system or as operational envelopes change over time. These new hazards, and their associated risks, must be continually identified, evaluated and resolved.
