EH&S Management System
Our management system has its roots in Responsible Care®. A culture of rigorous investigation, corrective action, and continuous improvement applied over many years has delivered a world-class set of internal policies, processes, and procedures.
This system, which includes all Trinseo employees and people doing work on behalf of Trinseo or working in our facilities, is designed to meet Trinseo’s Environmental, Health, and Safety (EH&S) objectives, which include:
- Continually reduce EH&S incidents and risks
- Maintain full regulatory compliance
- Satisfy stakeholders expectations
- Optimize resources and continuously improve
Trinseo has developed a strong set of leading indicators to help highlight and drive improvement across the organization. These indicators reflect:
- Training completion
- Engagement in behavioral improvement program
- Equipment mechanical integrity inspection completion
- Timely assessment of changing regulatory requirements

Behavioral Improvement Training
An atmosphere of highly interactive and constructive worker and leader interactions is fully embraced in the Trinseo culture. At the level closest to the work, leaders frequently engage with workers in Safety Conversations as part of Trinseo's behavior-based safety program, Safety on Purpose. The program creates open, constructive exchanges on work tasks, including the risks involved and ways to make the task even safer.
Selected workers are provided 20 hours of training to become Safety Influencers and effectively perform Safety Conversations. These influencers and plant leaders meet weekly to discuss Safety Conversations, during which they address safety concerns and opportunities identified during the previous week, identifying appropriate resolution and follow up.
Safety on Purpose was introduced in 2017 in our facilities and continues today to improve collaboration and engagement between workers and leaders in addressing and resolving safety opportunities in the facility.
