Hazard Analysis Tool

This piece of code is composed of the following codes:

• call_hazard.py
• main_hazard.py
• get_constraints.py
• hazard_class.py

This piece of code is not exhaustive is a primary idea to generate a code to perform a hazard analysis qualitatively based on the "bowtie" analysis. The idea is to develop a simple prototype for a more complex tool to perform risk analysis.

It is a function used to interact with the main_hazard code and initialize the collection of information about a "hazard analysis." This function collects and stores the data in a "txt" file.

It is a function used to interact with the other two codes, "get_constraints" and hazard_class. This function calls the other two functions and defines some figures necessary to perform the analysis.

It is a collection of small pieces or functions to perform tasks necessary to store data.

In this file are defined all classes for hazard analysis.

• Hazard id
• Hazard statement
• Undesirable Event
• Safety Events - Causes
• Barriers
• Outcomes
• Mitigations
• Likelihood - Associated with undesirable event
• Severity - Associated with Outcomes
• Risk - Associated with each outcome
