COENG is determined to adhere to standards creating safe working environments. By working safely, we are more efficient and we can respond and react much faster to our changing world and workplace situations.


• TECHNICAL INTEGRITY: Well-designed installations, maintenance and inspections must ensure the technical integrity of installations.
•SAFETY MANAGEMENT: Safety policy and organisation, risk management, audits and assessment by management must ensure the safety within your organisation.
•SAFETY CULTURE is created through leadership, ownership, attitude, behaviour, (implicit) assumptions, perceptions and habits within a company with regard to dealing with safety risks.


COENG can support your organisation by increasing the safety of the technical installations, setting up and optimising your (safety) management systems and achieving changes in employee behaviour.


Our experts and consultants can support your organisation in all areas with the monitoring, testing and improving of your safety performance.


We cover the following areas: Audits / Compliance / Machine safety / Management systems / Accident investigation / Risk assessment / Training / HSE Plans / Safety studies / Workplace survey.

An environmental management system solves these issues by providing a framework within which to manage environmental obligations efficiently and effectively.
