ASBESTOS ANALYSIS

Asbestos survey / analysis / measurement

Asbestos (asbestos) is a naturally produced fibrous silicate mineral, and is the causative agent that causes lung cancer, malignant mesothelioma, etc. due to inhalation through the mouth or nose.
Therefore, the Occupational Safety and Health Act, the Air Pollution Prevention Law,
Prevention and scattering prevention etc. are being carried out by laws and regulations relating to waste disposal and cleaning.

We check whether these things contain asbestos,
We will help prevent it from scattering into the air due to weathering or demolition work.
An asbestos professional (qualified person) will provide total support for the investigation.

Asbestos survey / analysis

Asbestos (asbestos) is a naturally produced fibrous silicate mineral,
It is the causative agent that causes lung cancer, malignant mesosplenomegaly, etc. due to suction from the mouth or nose.

For this reason, prevention and scattering prevention etc. are being carried out by the Occupational Safety and Health Act, the Air Pollution Prevention Law, and laws relating to waste disposal and cleaning. We accept preliminary investigations (written surveys / visual surveys) and analytical surveys before building demolition and renovation work by qualified personnel with experience and achievements.

Preliminary investigation (investigation of the presence or absence of asbestos to be carried out prior to building demolition and renovation work)

For all parts subject to construction, Investigate whether asbestos is contained in advance with documents such as design documents and on-site visual inspection, and store records of survey results for 3 years It is mandatory. (Reiwa 3/4-)
Also, preliminary investigation of buildings Have those who have completed the courses determined by the Minister of Health, Labor, and Welfare perform It is mandatory. (Reiwa 5/10-)

At our company, There are multiple building materials researchers with experience and achievements We are doing it, and we will respond quickly.

“I want to conduct a preliminary investigation, but there are no qualified investigators...”

“I have obtained the qualification of an investigator, but I don't know how to proceed with the investigation...”

“I can do an investigation, but I don't know a company that can request subsequent analytical research...”
etc.,
Please feel free to contact us if you are having trouble carrying out the preliminary investigation.

Asbestos content analysis

By preliminary investigation (written survey / visual survey) We analyze building materials that cannot contain asbestos, and determine whether they contain asbestos.

Collecting analytical samples Qualified personnel with knowledge of asbestos-containing building materials will be implemented.

The analysis method complies with the asbestos analysis manual for preliminary surveys based on the asbestos law and the JIS A 1481 standard group.

Asbestos dust concentration measurement

For the purpose of preventing health hazards, according to the Occupational Health Standards Act, Asbestos Injury Prevention Regulations, Air Pollution Prevention Law, etc.Asbestos handling and management laws are stipulated.


Each prefecture has prepared research and analysis manuals based on these laws.

We accept sampling and measurement according to each manual.

We measure the concentration of asbestos dust in the air during asbestos removal work.

It is carried out using measurement methods based on JIS A 3850-1, asbestos monitoring manuals, and measurement conditions determined by each prefecture.

In addition, we also accept atmospheric measurements for general environments.

Measurement conditions, measurement locations, etc. may differ depending on each prefecture. Please feel free to contact us.

Sampling and analysis method for asbestos dust concentration measurement

Asbestos dust concentration measurements are basically carried out using measurement methods based on JIS K 3850-1, asbestos monitoring manuals, and regulations. The basic sampling and analysis methods are as follows.

  • Prepare a filter holder and air sampler with a membrane filter set according to sampling conditions.
  • The filter holder is attached to the suction side of the air sampler and fixed to a tripod at a height of 1.2 to 1.5 m in the direction of the target building.
  • Match the suction flow rate of the air sampler to the sampling conditions and start sampling.
  • The membrane filter is removed from the filter holder where sampling has been completed, and a sample is prepared using acetone / triacetine.
  • The prepared sample is checked with a microscope, and fibrous materials with a length of 5 μm or more, a width (diameter) of less than 3 μm, and a length-to-width ratio (aspect ratio) of 3:1 or more are counted and measured.
  • The measured number of fibrous substances is applied to the formula for total fiber concentration to calculate the asbestos dust concentration.
  • When the asbestos dust concentration comes out, it will be sent by email (fax is also possible) as an update of the measurement results.
  • Once measurements of all work processes have been completed, measurement results, measurement conditions, measurement records, measurement location diagrams, and measurement photographs are compiled and submitted as a report.
