• Step.0

  Grasping of substances used
  Based on the safety data sheet (SDS), grasp the substances included in the chemical agents currently used by the business owner.
  Check for the presence or absence of harmfulness.

  * The manufacturer is obliged to report the SDS to the sale destination.

  
• Step.1

  Grasping of current situation (working environment measurement)
  Measure the environmental concentration in the work process and check if the measured concentration is the acceptable concentration or less in the working environment.

  Evaluating Respirators with Fit Testing Fit Testing Service

  SDG conducts quantitative fit testing, an evaluation method that has been adopted worldwide.

  What is fit testing?

  Fit testing is used to determine the suitability of the welding respirators typically worn by workers.
  This service uses a dedicated measuring device to determine whether a particular respirator fits a worker’s face perfectly.
  On April 1, 2023, fit testing becomes a legally required procedure.

  SDG’s Services

   

  • We perform quantitative fit testing that meets global standards.
    
  • Since we report the testing results in numerical form, the purchaser can use the information provided to make the proper choice.
    
  • The results of the fit test can be used to identify needed improvements to the work environment.
    

    

  

   

  Fit Testing Methods

  Two fit testing methods are available: the quantitative fit test and the qualitative fit test.
  Measurement records must be retained for a period of three years.

  Quantitative Fit Test

  

  

  • Results are recorded with a dedicated measuring device.
  • Accurate numerical values can be obtained.

  Qualitative Fit Test

  

  • The subject is asked to detect taste and odor during the test procedure.

  

  At SDG, we provide highly accurate quantitative fit tests designed to improve the work environment.

  After working environment measurement, 1st to 3rd management categories are applied.

  

  Onlya working environment measurement agency can make working environment measurements.
  SDG is a working environment measurement agency registered company.
  We can measure and evaluate the concentration!

  

  We will provide one-stop actions not only for examination, planning, designing, notification, construction, inspection/maintenance, environment measurement and production execution but also for notification document and working environment assessment.

• Step.2

  Improvement equipment planning (engineering and equipment measures)
  Based on the environment measurement result and the laws and regulations, make improvement equipment planning and submit a plan to the relevant public office as needed.

  LEARN MORE

   

  
  1. Engineering measures and preparation of notification document Based on the environment measurement result, plan equipment complying with the laws and regulations.

  

  

  Engineering measures: Designing and construction of exhaust system and dust collector

  Notification document: Preparation of application form for Labour Standards Bureau

  Measures for fundamentally eliminating dangerous work are called qualitative measures (essential safing). When it is difficult to solve problems with qualitative measures, pursuant to engineering measures (equipment measures), measures using equipment and management measures are considered. Personal protective equipment is positioned as final measures.

  2. Visualization of existing duct Visualize the existing piping equipment and conduct properness diagnosis.

  

  

  

  3. Making an airflow analysis for avoiding a risk at the time of introduction of new equipment Airflow Analysis Service

  We solve problems such as excessive heat accumulation in order to optimize the temperature inside the plant.

  

  Before implementation

  

  

  After implementation

  We provide manufacturer-support services by utilizing thermal fluid analysis software and employing the expertise we have acquired as a blower manufacturer to optimize factory temperatures.

  POINT!

  • Addressing excess heat
  • Providing overall ventilation
  • Increasing the efficiency of existing air conditioning equipment
  • Analyzing the movement of suspended particles and developing countermeasures

  

  Pre-installation simulations can eliminate the need for corrective work and other wasteful remedies.

  4. Digital Mapping Service

  We will examine and analyze your plant and suggest improvements to the work environment.

  • 1Customer’s plant

    Typical measurement challenges

    • Plant is large.
    • Structure is three-dimensional.
    • Ductwork and piping are complex.
    • Structure requires a long time to examine.

    
  • 2Survey with 3D laser scanning tools
    provides point cloud data of the plant.
    
  • 33D CAD data provided by SDG.
    

  To provide technical services to our customers, our specialist employees obtain survey data with dedicated measuring instruments.

  Because detailed site information is recorded, confirmation work can be performed with accuracy at the desk.

  

  Analysis

  The created 3D model can be used to perform airflow analysis that includes wind speed, static pressure, temperature, pollution levels, and noise levels.

  

  Targets for improvement of overall ventilation as well as countermeasures for excess heat are highlighted.

  Construction plan

  A construction plan can be developed with reference to the actual onsite situation.

  

  

  Equipment maintenance

  A maintenance list can be created by layering the target devices in the scanned data.

  High-altitude surveying with drones

  Typical Services

  Dimensions can be confirmed with point cloud data, and information can be shared through the cloud once it has been processed into 3D data using a technology called Structure from Motion (SfM), a photogrammetric range imaging technique. This process combines multiple images captured at mapped inspection points.
