The Electronic Code of Federal Regulations (eCFR) is a continuously updated online version of the CFR. 
There shall be no damaged parts that may adversely affect safe operation or mechanical strength of the equipment, such as parts that are broken, bent, cut, or deteriorated by corrosion, chemical action, or overheating. The factors that must be considered in making this determination include, but are not limited to: Conditions affecting atmospheric conductivity; time necessary to bring the equipment, load line, and load (including rigging and lifting accessories) to a complete stop; wind conditions; degree of sway in the power line; lighting conditions, and other conditions affecting the ability to prevent electrical contact. 
There are gobs of places that I've opened up boxes, switches, disconnects, et al that I have opened up for trouble shooting that didn't have required work space. 1Minimum depth of clear working space in front of electric equipment with a nominal voltage to ground above 25,000 volts may be the same as that for 25,000 volts under Conditions A, B, and C for installations built before April 16, 1981. The workspace also must permit at least a 90-degree opening of all hinged panels and equipment doors. Outdoor electrical installations having exposed live parts shall be accessible to qualified persons only. Insulated wire or insulated busbars operating at not over 300 volts are not considered live parts. Others will place the square around the area and then use diagonal stripes of floor markings to fill out the area, which makes it even more clear that nothing should be put in that place. Note to paragraph (g)(1)(vii)(A) of this section:A dropped, suspended, or similar ceiling that does not add strength to the building structure is not considered a structural ceiling. Having an electrical panel clearance policy in place is very important not only for practical reasons, but also in order to comply with various regulations.
