Safety Team

This team was formed to foster a safety culture within the organization. Haller Enterprises, Inc's Safety Committee meets monthly to discuss topics ranging from personal protection equipment to back strains to trench safety. It also makes recommendations to management on ways to increase safety awareness. As an ongoing commitment to a safe work environment, "Tool Box Safety" talks are part of monthly department meetings and bi-weekly safety awareness bulletins are distributed to employees. Site audits, completed by an external safety consultant, are part of this commitment. The safety program at Haller has been recognized with the following awards from the Associated Builders & Contractors Keystone Chapter:
