Mineral dust
In Japan, the measurement of mineral dust is basically carried out by “filter collection method using a particle separator” and “mass concentration measurement method using a balance”, but in consideration of workability in the field, it is operated by A measurement, B measurement, and parallel measurement using a simple measuring instrument (digital dust meter).Sibata offers a wide range of simple measuring instruments (digital dust meters) that correspond to the relative concentration indication method.
On-site A measurement, B measurement, parallel measurement
At the measurement site for mineral dust, an air sampler with a PM4 particle separator and a digital dust monitor are used.

Respiratory protective equipment (mask) fitting management
According to the Asbestos Scattering Leakage Prevention Measures Thorough Manual, workers working at the asbestos removal work site are required to wear respiratory protective equipment (mask) without any gaps to prevent inhalation of asbestos.We will introduce our products used to wear respiratory protective equipment (mask) without any gaps with reference to the manual.
Measurement of the adhesion rate of the mask to the face
It is important for the wearer to correctly select the dust mask that fits his / her face and to carry out wearing training on a daily basis.If the degree of adhesion between the mask and the face is low, external air will enter the mask through the gap.
It is a measuring instrument for measuring the fitness between the mask and the face. You can measure while checking the wearing condition of the mask with the attached mirror.
