Measurements
Diisocyanate measurement (MDI, TDI, HDI)
PUR foams, painting or bonding with isocyanates? We measure exposure to MDI, TDI, HDI and other diisocyanates in actual operation — report for KHS and job categorisation.

- technical and organisational measure recommendations
When you need this service
- Job categorisation or regional hygiene station request regarding isocyanates
- PUR spraying, painting or bonding with diisocyanates in operation
- Technology, materials or ventilation change for reactive systems
- Verifying extraction and PPE effectiveness after a complaint or inspection
Documents and preparation
What to send us
- safety data sheets of materials and mixtures used
- description of work operations, extraction and PPE
- workplace layout and shift pattern
- regional hygiene station requirement or internal audit documentation
Typical mistakes and risks
- Exposure estimated from safety data sheet only without operational measurement
- Measurement outside peaks during spraying or pouring
- Failure to consider secondary emissions during further PUR processing
Typical situations
- MDI measurement during PUR foam production and processing
- TDI exposure in paint shops and polyurethane system application
- measurement during bonding and lamination with isocyanate adhesives
- secondary emissions during heating or cutting cured PUR materials
Frequently asked questions
When is workplace environment measurement required?
Workplace environment measurement is addressed during job categorisation, technology change, a new workplace, KHS instruction or when verifying employee exposure.
Which workplace environment factors do you measure?
Typically dust, chemical substances in workplace air, noise, vibration, lighting, microclimate and other factors depending on workplace characteristics, technology and work activity.
Can measurement serve as documentation for job categorisation?
Yes. Workplace environment measurement results are often used as documentation for job classification or reclassification.
Who may carry out measurement for job categorisation?
Measurement for classification into category 2, 3 or 4 may only be carried out by the employer through a holder of an accreditation certificate or authorisation for the relevant measurements, unless the employer is so qualified.
What is hazardous work?
Hazardous work is work classified in category 3 or 4, and also category 2 work designated as such by the relevant public health authority.
