Eaton UPS and Battery Safety

UPSs protect and power the equipment that runs essential business systems, industrial and medical processes, and communications networks. Everyone should be aware of the risk that these vital pieces of equipment possess along with other power infrastructure equipment.

Safety is an embedded value at Eaton. Be assured that while Eaton employees are working at a customer facility or site, they will be following Eaton and industry best practices for protecting equipment and maintaining a safe and hazard-free environment.

Safety records

Eaton’s recordable incident rate is consistently below the industry average for operations in the NAICS code 811 category (Repair and Maintenance). Our experience modification rate is also consistently below the industry average—and has been for a significant period of time.

Training and safety protocols

In addition to equipment specific training certifying field technicians to work on particular UPS models, they receive classroom style training that includes standards review (OSHA, NFPA 70E, ANSI, etc.), group case studies, demonstrations, and competency observation and testing.

In addition, a safety council of experts addresses issues and complicated safety questions that arise in the field.

EHS Team

Eaton’s Environmental Health and Safety (EHS) team receives unequivocal management support in promoting safety, even when it costs Eaton more and/or exceeds industry standards.

The EHS team works with the engineers who design the UPSs to drive safety further upstream in the power chain. For example, rather than a field technician donning protective gear to do voltage readings, they can now be taken remotely, with no risk to the engineer.

Eaton constantly strives to design more elements to reduce exposure and improve safety—as well as making UPSs easier and faster to service.

Service availability

Eaton has service offices strategically located throughout North America and Mexico.

Eaton’s Engineering Services team offers services tailored for every stage of a power system’s life cycle, whether it’s design, build or support. Our services integrate and optimize the elements of a power system to make sure it’s aligned with business goals. We can help keep your power system safe, efficient, reliable and up-to-date.

Arc flash safety

Protect what matters most. If you haven't taken the proper steps to mitigate the risks of arc flash, you're compromising worker safety, and you could be breaking the law. Use the resources here to reset arc flash safety in your facility.

Following industry guidelines, a customer engineer may conduct the following preventive maintenance activities. Beyond this sample, IEEE Std 450-2010 outlines comprehensive guidelines for monthly, quarterly and annual maintenance.
