Rapid Post-Earthquake Building Safety Assessment

What is Rapid Safety Assessment?

Rapid Safety Assessment is the inspection of buildings immediately after an earthquake in order to assess the risk of collapse of outer walls, breaking of windows, and destruction of connected devices in the ensuing aftershocks. The objective is to prevent secondary disasters that might take human life, and the results allow for the provision of information regarding the risk of making use of buildings after an earthquake while permanent restoration is being conducted.

Consequently, this is not a disaster inspection for the sake of a `Disaster Victim Certificate`, which is needed to receive support under the `Natural Disaster Victim Support Law`, but rather a rapid assessment of whether a building can be used or not.

Since this assessment involves building specialists directly visiting each and every building it also leads to the emotional stability of disaster victims who are anxious about the state of their buildings.

As the Rapid Safety Assessment is one of the rapid counter-measures instituted after an earthquake by the municipality, it is initiated based on the decision of the Municipal Disaster Counter-Measures Headquarters. In situations like the recent Great Eastern Japan Earthquake where large numbers of buildings over a wide area are damaged, upon request of the Municipal Disaster Counter-Measures Headquarters, Ibaraki Prefecture collaborates with relevant civilian organizations to dispatch `Rapid Safety Assessors`.

*In order to determine whether Disaster Victim Certificates or Rapid Safety Assessments are available in your area, please contact your municipal government.

What is a Rapid Safety Assessor?

Ibaraki Prefecture conducts development and registration of `Rapid Safety Assessors` by having architects and other technical experts who volunteer from the community and government employees who are connected to construction undergo training for rapid safety assessment.

When `Rapid Safety Assessors` are conducting activities related to assessment they will always be carrying documents verifying their identity, and wearing arm-bands and helmets that state they are `Rapid Safety Assessors`.

Assessment Operations

Assessment operations are conducted by teams of two who make objective assessments based on the criteria determined by the inspection sheet.

The inspection is conducted mainly by visual examination of the outer premises, without entering buildings that are thought to be dangerous.

Indication of Assessment Results

Based on the results of their Rapid Safety Assessment, the assessors will indicate with stickers placed on easily noticeable places like the entrance or exit what level of risk there is, broken down into 3 categories: `Unsafe`, `Limited Entry`, or `Inspected`.

This is so that people who make use of the building in question, principally the residents but also pedestrians who pass close by, can easily discern whether the building is safe or not.

In addition, the assessment stickers also display simple explanations on methods to handle the situation based on the assessment results and procedures to prevent secondary disasters. In cases where the building owner is present, they will be given an explanation of the results of the assessment and briefed on how to avoid any danger.

Furthermore, contact information for enquiries is also listed on the stickers.
