Reference Answer

### Introduction to Formal Safety Assessment (FSA)
Formal Safety Assessment (FSA) is a structured and systematic methodology, promulgated by the International Maritime Organization (IMO), aimed at enhancing maritime safety, including the protection of life, health, the marine environment, and property. It achieves this by employing risk analysis and cost-benefit assessment. The core principle of FSA is to provide a proactive, transparent, and justifiable framework for the rule-making process, moving away from a historically reactive approach (i.e., making rules after an accident) to a proactive one based on risk evaluation.
### The Generic Five-Step FSA Model
The FSA framework is composed of five logical steps that guide the analysis from hazard identification to the final recommendations.
