Fire Protection Analysis

Types of Analysis

Hazard Analysis
If you fail to plan; you plan to fail

Fire Protection Hazard Analysis is a process that identifies potential fire situations before they become actual events.

The process of working through every aspect of a building (construction, materials, operations, storage, occupancy, etc.) will give the fire protection professional insight into areas of hazard that should be addressed. These discovered hazards could be an immediate concern or could become more hazardous over time.

Identifying hazardous situations or procedures should be a large part of the overall fire safety plan in an effort to protect the building, the occupants, and the building’s contents.

The following articles and associated NFPA codes provide an overview of the Hazard Analysis process.


Fire Inspection Checklist

A comprehensive fire inspection/hazard analysis checklist can be assembled using:

  • Current checklists being used by others (internet search)
  • Local fire marshal list of code violations
  • NFPA
  • Experience

Review the following Fire Inspection Checklist examples:

Event Tree Analysis

From Event Tree Analysis:

Event Tree Analysis (ETA) is a forward, bottom up, logical modeling technique for both success and failure that explores responses through a single initiating event and lays a path for assessing probabilities of the outcomes and overall system analysis. This analysis technique is used to analyze the effects of functioning or failed systems given that an event has occurred.

ETA is a powerful tool that will identify all consequences of a system that have a probability of occurring after an initiating event that can be applied to a wide range of systems including: nuclear power plants, spacecraft, and chemical plants. This Technique may be applied to a system early in the design process to identify potential issues that may arise rather than correcting the issues after they occur.

With this forward logic process use of ETA as a tool in risk assessment can help to prevent negative outcomes from occurring by providing a risk assessor with the probability of occurrence. ETA uses a type of modeling technique called event tree, which branches events from one single event using Boolean logic.
