Health, safety, environment and quality are in the DNA of the MSO Group. A safe working environment, together with compliance with laws and regulations, is a basic element for all work. The MSO Group strives for an incident-free working environment, every day and everywhere.


Competence is demonstrated by following the correct processes and carrying out work optimally. However, especially in the (petro)chemical industry, it is essential to be able to demonstrate this expertise through certification. The MSO Group is provided with all necessary certificates. Our trained staff is always able to carry out all work professionally and in accordance with contemporary requirements.

An annual internal audit tests the standards below. Unannounced external audits of the certification body also take place at project locations and in the office. Any points of attention are adjusted in the processes of the MSO Group. The staff and any subcontractors are informed about this via toolbox meetings.
