Rooms or enclosures containing electrical equipment controlled by a lock are considered accessible to qualified persons [110.26 (F). Remember, the NEC and OSHA give the minimum working space distances for various types of conditions. Those are not the average, maximum, or target distances.
For large equipment containing overcurrent, switching, or control devices, an entrance to (and egress from) the required working space at least 24 in. wide and 6½ ft high is required at each end of the working space [110.26 (C) (2)]. This requirement applies for either of the following conditions:
Based on findings like these, a minimum safety distance of 1/4 mile (1320 feet) might be considered prudent. And again, individuals with EMF hypersensitivity or other serious health issues may want to consider a much greater safety distance, perhaps a half mile, or even more.
Dedicated electrical rooms should never be used for storage, and a clear path of travel should be maintained for emergency egress. Oftentimes, these rooms become a catchall for everything from spare light bulbs to office supplies. Inspectors should report on relevant findings in their report.

Global Power Supply provides a full range of battery cabinets engineered to extend UPS runtime, protect sensitive loads, and maintain continuity in any environment. A UPS system provides immediate backup power during an outage. Paired with compatible UPS battery cabinets, your facility gains extended power capacity and greater resilience.
A battery cabinet houses and protects the batteries that supply stored energy to a UPS system. It ensures that backup power is readily available whenever primary power is interrupted. Battery cabinets can be installed indoors or outdoors and are designed to provide secure, organized, and scalable energy storage for continuous power delivery.
Global Power Supply offers battery cabinets from industry-leading manufacturers such as Toshiba and Narada, available in multiple configurations to match your specific operational needs. Because every facility's power requirements are unique, we can help tailor the number of cabinets, capacity, and layout to meet your space and runtime objectives.
This document provides standards for battery room design and operation. It outlines requirements for civil construction including fire resistance of walls and floors, as well as plumbing, ventilation, electrical systems, and safety/maintenance.
Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability and safety, as well as human comfort. The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration.
The room shall be equally illuminated throughout the entire battery room. 1. The installation shall consist of energy efficient luminaires. 2. The maintained level of emergency lighting required in this area shall not be less than 20 lux at floor level to enable employees to evacuate the workplace safely. 3.
