# Overview
Working versions of Class 1 and 2 risk assessment standard operating procedures (SOPs) can be accessed via the sidebar on the left, or by clicking applicable links in the table below, which summarizes the SOPs that are currently available and the suggested applicability.
| Hazard | Class 1 SOP | Class 2 SOP | Scope |
|---|---|---|---|
| Flood | Available | Available | Analysis type: Archetype-based Hazard type(s): Riverine, Stormwater, Coastal Asset type(s): Buildings Consequence(s): Downtime, Repair cost Region(s): All |
| Earthquake | Available | Coming soon | Analysis type: Desktop study Hazard type(s): Earthquake shaking Asset type(s): Buildings Consequence(s): Downtime, Repair cost Region(s): USA |
| Wind | Available | Available | Analysis type: Archetype-based Hazard type(s): Non-tornadic wind Asset type(s): Buildings Consequence(s): Downtime, Repair cost Region(s): USA |
| Wildfire | Available | Available | Analysis type: Archetype-based Hazard type(s): Wildfire heat/flames, Embers Asset type(s): Buildings Consequence(s): Downtime, Repair cost Region(s): USA |
Each SOP summarizes the standard risk assessment methodology for the relevant hazard based on the following steps:
- Quantify hazard
- Quantify exposure
- Quantify vulnerability
- Quantify consequences
- Evaluate risk
For quantifying hazard, each SOP will direct the analyst to the recommended data source(s). For some hazards, this can be done through the Iris platform. For quantifying exposure, each SOP will explain how to classify assets (e.g. into archetypes) based on key characteristics. For quantifying vulnerability and consequences, each SOP will explain how to estimate the expected damage and/or consequences to the asset based on the hazard at the asset location and the asset's exposure. In some cases, vulnerability and consequences are assessed sequentially but in other cases the consequences are assessed directly with implicit vulnerability analysis. For evaluating risk, the likelihood and consequences for the asset associated with the relevant hazard are integrated, with the result being a risk rating and/or a quantitative measure of risk (e.g. average annual loss)
For some hazards, especially those for which archetype-based analysis is avilable, the entire workflow can be completed in Iris, including extracting hazard data, assigning archetypes based on asset characteristics, and performing the risk calculations. Where relevant, a video demonstrating the steps to perform the assessment in Iris will be provided within the SOP.
