Health & Safety

At STACK, we are committed to the safety and security of our employees, partners, clients, and the surrounding communities in which we live and operate. It is STACK’s responsibility to always do the right thing by providing a holistic safety experience and contributing to the well-being of our most valuable resources.

STACK is dedicated to continuous improvement, and our safety management system follows the philosophy of “Plan, Do, Check, Act” throughout every aspect of data center development and operations to achieve our zero-incident goal during the safety lifecycle:

Design Safety

STACK works with our architects, engineers, construction crews, and critical operations teams through a collaborative approach to evaluate our designs at key points in the process to eliminate the need for high-risk activities and deliver a product that is safe and efficient to operate and maintain.

Construction Safety

Safety in the construction phases of our projects requires a close relationship with our partners, open and transparent communication, and daily oversight to adjust as conditions change and always remain compliant with the local regulations and committed to best management practices.

Critical Operations Safety

STACK’s Critical Operations Playbook defines processes and controls and leverages principles outlined within ISO 45001 to ensure a safety-first perspective is embedded within our day-to-day operations of data centers, from routine tasks to unplanned and non-routine activities.


Safety starts at the top.

At STACK, we are devoted to being leaders in caring for the well-being of all. Our people are a differentiator and our best resource to successfully addressing the evolving environmental, health, and safety (EHS) requirements in our industry.
