Threat and Hazard Identification and Risk Assessment (THIRA)

Based on past experience, forecasts, subject matter expertise, and other available resources, identify threats and risks of concern.

Nature's threats and dangers are threats and dangers caused by natural behaviors such as hurricanes, earthquakes or tornadoes, the occurrence of disease or epidemics.

Technical threats and hazards are caused by accidents, system and structural obstacles such as leakage of dangerous substances or breakage of dams.

Artificial threats and hazards are caused by deliberate actions of the other party, such as threatened or actual chemical or biological attacks, or cyber incidents.

Based on the probability of occurrence and the importance of the impact, the community needs to choose the threats and dangers that are receiving the most attention.

In the next step, we will use a list of threats and risks to create context descriptions to show how these threats and risks affect the community. To establish a contextual description, consider factors that make this threat or danger in the jurisdictional area more difficult, such as time, place, state. For example,

When is the threat / hazard (time / season) and time likely to affect the ability of the community to manage it?

Where can threats / risks occur (such as densely populated areas, coastal areas, industrial areas, etc.) and how does that location affect the management capacity of the community?

What are other conditions (atmospheric conditions, multiple events) that can cause particularly serious threats or dangers?

Next, context descriptions are used to evaluate each threat and hazard within the context, and determine the level of competence required by the competent jurisdiction to achieve the desired result and the overall prepared goal.

The last step is to estimate the resources needed to achieve the functional goals and apply the THIRA results. Resource requirements are expressed as a list of resources needed to successfully manage the identified threats and hazards.

"This Threat and Hazard Identification and Risk Assessment (THIRA) Guide provides a comprehensive approach for identifying and evaluating risk and related impacts, which is a measure of the hazards of existing regions, tribes, Identification and Risk Assessment (HIRA) In other risk approaches, by consolidating the entire community throughout the process by considering the factors considered in the process, considering important community-specific factors, a step-by-step process Evaluate the community's vulnerability to the use of various factors of time, season, place and community Steps 3 and 4 evaluate the impact of threats and hazards affecting the community and evaluate the function of the core lens Construct capacity targets through.

FEMA issued a booklet titled "Threats and Risk Identification and Risk Assessment Guidelines" in order to assess potential threats and increase emergency supply and improve disaster response skills. (THIRA) This guide will outline the process of THIRA while emphasizing not only the government agencies but also the "involvement of the entire community" for preparation. In this guide, FEMA classifies the dangers into three categories: nature, technology, and artificial danger. And that the possibility and importance of each risk should be evaluated. According to the Federal Emergency Management Bureau, "The community needs to consider only threats and risks that may occur" "The community needs to consider only the threats and risks that have serious implications. "Time, place, and state where threats and risks may occur
