Our most important asset is our people from the frontline employees to our CEO and it is our safety culture that holds us all responsible. Our employees; clients; subcontractors; and the public are the first priority of consideration before we begin any project. No project or task is performed unless we have evaluated the risk involved, and have in place the required controls to ensure that all workplace parties get home safe at the end of every shift.

At E.S. Fox Limited, we are proud to have achieved certification in ISO 14001 and 45001 for our Head Office and Fabrication facility. We apply these principals across our entire organization.
