Trinseo and AIChE Center for Chemical Process Safety (CCPS) to bring workshops to engineering students in China

Sponsorship will expand Undergraduate Process Safety Learning Initiative from U.S. to China,part of AIChE's "Doing a World of Good" campaign

NEW YORK and BERWYN,Pa.,Sept. 26,2018 --Trinseo (NYSE: TSE),a global materials company,today announced a new partnership with the Center for Chemical Process Safety (CCPS)-- a subsidiary of the American Institute of Chemical Engineers (AIChE)-- to host process safety workshops for undergraduate chemical engineering students in China. The partnership was announced during the 6th CCPS China Conference on Process Safety,held September 25-27 in Qingdao,China.

Trinseo Sponsors Process Safety Learning Session for Chemical Engineering Students in China

This is the first student workshop outside the U.S. of the AIChE/CCPS Undergraduate Process Safety Learning Initiative,which combines process safety theory and real-world cases taught by process safety experts. Chemical engineering students from several universities in China will be invited to participate in a one-day "Student Workshop on Risk-Based Process Safety," which will be held in 2019 at Trinseo's manufacturing site at Zhangjiagang,China.

The curriculum of the workshops will be designed and delivered by CCPS,the authoritative global organization providing the technical community with expertise and proven curriculum materials on process safety. The student workshops in China will be delivered by Byron Sun,a safety expert and CCPS staff consultant. Sun has over 27 years of professional experience,including safety leadership roles at China Petrochemical Company (now SINOPEC) and DuPont China. Byron received a diploma from Shanghai Science and Technology University and a Master Degree from Tongji University.

Trinseo has been a supporter of the AIChE's Undergraduate Process Safety Learning Initiative and "Doing a World of Good" campaign since 2016 in the U.S. To support the program's expansion in China,the company will make an additional US$50,000 donation and provide in-kind support from Trinseo employees in China. In addition to hosting the student workshops locally,Trinseo also will support the development of Chinese-language marketing materials to promote CCPS's Safety and Chemical Engineering Education (SAChE) online learning modules,as well as additional translation of curriculum into Chinese.

"Trinseo is proud to be part of this effort to educate future generations of chemical engineers,and in particular to help bring the successful Undergraduate Process Safety Learning Initiative to China for the first time," said Chris Pappas,President and CEO of Trinseo. "Our employees in China are highly committed to process safety and training,so they are very excited to pass on their knowledge to the next generation of chemical engineers. This partnership with CCPS and AIChE is in line with Trinseocompany's values,our commitment to Responsible Care®,and our dedication to work safely in everything we do."

Shakeel Kadri,Executive Director of CCPS,explained the critical importance of the undergraduate workshops,noting that "employers tell CCPS that they need engineers who are better trained in process safety when they enter the workforce." However,Kadri added,chemical engineering schools around the world have not yet developed a standard process safety curriculum to fulfill that need. "Through CCPS's collaborations with organizations such as Trinseo,the Undergraduate Process Safety Learning Initiative is helping to ensure that every chemical engineering graduate acquires a basic knowledge and appreciation of process safety principles."
