Look for new requirements for keeping the area around electrical equipment (panels, shut offs, etc) clear. This is from a recent National Electrical Code update:
Keep It Clear:
Proposal for 2014 NEC would sharpen requirements for clear work space
Jeffrey Sargent
A proposed requirement for the 2014 edition of the National Electrical Code® (NEC®) addresses the ongoing need to maintain clear working space around electrical equipment that is likely to be worked on while energized. Energized tasks on electrical equipment are inherently dangerous, and the new requirement is based on the need to give qualified workers the necessary space so that their safe access to the energized parts is not compromised or impeded. An additional benefit of clear working space is that it provides the required ready access to overcurrent protective devices.
