Service overview

When you need this service

  • Regional hygiene station or job categorisation requires heat or cold stress measurement
  • Workers are exposed to heat at furnaces, dryers or outdoor work in summer
  • Operations in cold stores, freezers or unheated halls in winter
  • You need documentation for shift organisation and technical measures

What we provide

  • We measure microclimatic parameters according to Czech Ministry of Health methodology
  • We assess conditions according to physical work load (light / moderate / heavy)
  • We measure in halls, dryers, cold stores and during outdoor work
  • We recommend work class, permissible exposure times and fluid replacement

What you receive

  • heat or cold stress measurement report with assessment
  • work class and permissible exposure time recommendations
  • documentation for job categorisation, OHS and operational measures

Practical project examples

  • heat stress measurement at furnaces, dryers and hot operations
  • cold stress assessment in cold stores and freezers
  • measurement during outdoor construction and agricultural work

Typical mistakes and risks

  • Assessment based only on air temperature without considering physical work load
  • Measurement without considering actual operating mode and clothing
  • Incomplete description of ventilation, technology and shift pattern

FAQ for this service

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.
