Building relationships with qualified suppliers who support the operation of our business reflects the many cultures and backgrounds of our customers and helps us successfully deliver on our promises.

We take on high-risk work in hazardous environments for some of the largest companies and government groups. Day & Zimmermann is selected to perform this work because we know how to do it safely and our customers have confidence in our proven safety record. We take these responsibilities seriously and are relentless in our commitment to preventing injuries and accidents, as demonstrated in our comprehensive safety organization, training, tools and programs.

A Blend of Policy and Values
We know that safety does not occur by chance. It is the result of careful attention to all company operations, by all who are directly and indirectly involved. It relies on a culture that drives employees at all levels to work diligently to execute our policy of maintaining occupational safety and health as our most important value and striving for the highest level of safety performance in all aspects of our business.

Regard for the safety of our employees, our customers' employees and the public is the responsibility of every employee. And working safely is a condition of employment at Day & Zimmermann. All employees are empowered and obligated to manage and perform work activities in compliance with regulatory standards, company procedures and safe work practices. Safety is not simply another thing we look to control, it is what drives how we manage, perform and live. Our approach to safety unites management participation and leadership with employee ownership and the implementation of consistent policies across the organization.

Day & Zimmermann Safety Council
Comprised of safety leaders representing each of Day & Zimmermann's business units, the Council exists to address emergent safety challenges across the variety of industries we serve. Reviewing each unit's safety performance and sharing lessons learned are just part of the Council's quarterly meetings. Annually, the Council plans a two day summit, inviting key leadership and management personnel from across the company to participate in an intense review of the state of our safety culture, key trends and issues and strategic plans. Most recently, the challenges addressed by the group included off-the-job safety for our employees and pandemic preparedness for our own company and our customers' operations.




At Day & Zimmermann, success is all about making a difference -- for our customers, our employees and the communities in which we live and work.

Our people are the key to our success. Day & Zimmermann strives to make a difference in the lives of our employees by providing them with opportunities to grow and develop in their chosen careers, while performing as part of a world-class team. We support their growth through extensive training and development programs aimed at building the skill sets and experience needed to keep pace with our rapidly changing markets.

As a large enterprise we understand the ability we have to make an impact on our communities, as well as the significance of this responsibility. Whether it is our families, friends, neighborhoods or cities, making a difference in our communities means we are involved with and give back to others in meaningful ways. As part of our commitment to the success of our communities, Day & Zimmermann is proud to be affiliated with numerous charitable and civic organizations through our corporate efforts, the direct outreach of our Employee Network Groups, and the grassroots efforts of employees throughout our network or offices.
