Overview of Asbestos Regulations under the Building Standards Law

Restrict the use of asbestos in buildings to prevent health hazards caused by asbestos.

• If there is a risk of scattering asbestos, such as sprayed asbestos, it may cause health damage to building users.
• For this reason, in the future, regulations on the use of asbestos in buildings will be introduced so that health hazards due to asbestos scattering will not occur.

Restrict the use of building materials that could cause asbestos scattering.
※ Specifically, sprayed asbestos and asbestos-containing sprayed rock wool (more than 0.1% weight) are subject to regulation.
[Effect of regulation]
(1) Duty removal at the time of extension or renovation
(2) Implement recommendations, orders, etc. when there is a risk of asbestos scattering
(3) Listening to reports and on-site inspections
(4) Conduct browsing through the periodic reporting system

Date of enforcement: October 1, 2006

1. To determine asbestos as a material that is extremely harmful to hygiene due to scattering.
2. At the time of extension / remodeling, asbestos must be removed in principle, but for extension / remodeling where the floor area of the extension / remodeling where the floor area of the extension / remodeling does not exceed 1/2 of the floor area before extension / remodeling, measures for containment and enclosure other than the extension / remodeling area To allow.
3. At the time of large-scale repairs and remodeling, measures for containment and enclosure of parts other than large-scale repairs and remodeling parts shall be permitted.
4. For structures, regulations similar to buildings for asbestos, etc.

Revision of the Building Standards Law Enforcement Regulations

• At the time of extension or remodeling, at the time of large-scale repair or remodeling, specify the location of the measures on the floor plan of each floor of the building confirmation application.
• In the periodic survey report, indicate the presence or absence of sprayed asbestos, etc., and whether there is a plan to take measures. (Effective on April 1, 2007)

Notification (2006 Notification No. 1172) that specifies building materials in which asbestos is not likely to be scattered or dispersed in advance (2006 Notification No. 1172)

• As building materials in which asbestos is not likely to scatter or disperse asbestos is added in advance, building materials that add asbestos other than sprayed asbestos and asbestos-containing sprayed rock wool should be determined.

Notification (2006 Notification No. 1173) stipulating standards for containment and enclosure measures
(1) Standards for containment measures

• Using asbestos scattering prevention agents (hereinafter referred to as "prevention agents") certified under Article 37 of the Building Standards Act, cover building materials with asbestos added or attach the added asbestos to building materials. thing.
• If there is significant deterioration or damage to the building material to which asbestos has been added, take measures to prevent asbestos from scattering from the relevant part.

(2) Standards for Enclosure Measures

• Enclose building materials to which asbestos is added with asbestos, such as boards, with non-transparent materials.
• Take measures to prevent asbestos from scattering from such parts when there is significant deterioration or damage to building materials to which asbestos has been added.

Notification that partially revises the 2000 Notification No. 1446 (2006 Notification No. 1168)

• Add prevention agents used for containment measures to be certified under Article 37, Paragraph 2 of the Building Standards Act.
• Establish the following technical standards for the quality of preventive agents:
• (1) Establish the following technical standards for the following quality:
• B. The standard value for the lower limit of the amount of protective agent applied shall be established.
  B. Fibers scattered from the building material when winds such as air conditioning equipment apply to the building material applied with the prevention agent are not recognized.
  Ha. When a solid object collides with a building material that has been applied with a preventive agent, the depth of the hollow generated will be larger than when the preventive agent is not applied, and it will not fall off or crack.
  Ni. When the tensile force is applied to the building material to which the protective agent has been applied, the adhesion strength of the coating film or adhered layer does not decrease according to the protective agent.
• (2) As inspection items, determine the composition of the preventive agent, etc., and determine the inspection method, such as according to the delivery note of materials.
