Why Work at Westlake

Our Commitment to Safety
More than 30 years ago, the words of Westlake founder T.T. Chao – now displayed on a plaque at every Westlake facility – established the company’s culture of safety. He said, “We have put safety first, and it will remain our number one priority. No job can be so important or urgent that people cannot take time to work safely. Life is precious and irreplaceable.” We take these words to heart everyday and apply a disciplined approach to keeping our employees and communities safe.
