How do you train your employees?

  • All our employees are trained in a 2-week basic training course to become “Clean Operators”. This teaches them the basics of how to behave in cleanrooms.
  • They are trained to behave correctly in your cleanroom and to carry out the cleaning and disinfection processes in a reliable and qualified manner.
  • According to our training plan, all employees must complete three continuous training courses per year (quality training courses). The training programme is rounded off by contingency-specific training courses.
  • Finally, we have established a multi-stage individual internal qualification system.     

How does CWS cover itself in the event of absences due to illness?

We employ additional staff in order to be able to deploy trained personnel whenever necessary due to absences.

Depending on the size of the location, there is always a personnel buffer and regional and national “sweepers”.

Depending on the extent of the damage, we can be on site quickly. For small jobs, we will be there within 2 hours, for larger jobs we should have enough staff on site within 24 hours.
