Sprayed asbestos (sprayed asbestos)

Sprayed asbestos refers to sprayed building materials containing asbestos.

Asbestos (also known as Asbestos (Ishiwata, Sekimen)) is a natural mineral fiber and has been used in many buildings because it is resistant to heat and friction. However, asbestos fibers are extremely thin and light, so they are easy to float in the air and are easy for humans to inhale. Inhalation of asbestos can remain in the lungs for a long period of time, which may cause lung cancer, asbestos lung, malignant mesothelioma, etc.

Overview of Business

System leaflet (PDF: 4,843KB)

　　This project is about sprayed asbestos installed on private buildings (stores, offices, parking lots, etc.) used by many people.
　　This is a business that provides free content surveys and subsidies for construction work such as removal.

Survey of sprayed asbestos content

　A professional contractor commissioned by the city visits and investigates whether asbestos is contained in sprayed building materials free of charge.

Sprayed asbestos removal, etc. (subsidy for construction costs)

　When taking measures such as removal of "sprayed asbestos" or "sprayed rock wool containing asbestos"

　 Supports 2/3 of the cost (up to 3 million yen). (Consumption tax is not eligible for assistance.)

There are two types of countermeasures that are subject to the project.
①Removal method	②Containment method
Method Method of removing sprayed asbestos from the base Features This is the most reliable measure.	Method Method of impregnating sprayed asbestos with chemicals and fixing them to prevent scattering Features Although it is cheaper than the removal method, it is a temporary response, and appropriate maintenance is required after construction. In addition, when dismantling a building, it is necessary to remove asbestos before dismantling. ※Depending on the condition of existing sprayed asbestos, it may not be possible to use it.

　　Enclosure work is not applicable
