Window wells required for emergency escape and rescue shall have horizontal dimensions that allow the door or window of the emergency escape and rescue openings to be fully opened. The horizontal dimensions of the window well shall provide a minimum net clear area of 9 square feet (0.84m2) with a minimum horizontal. projection and width of 36 inches (914 mm). Exception: The ladder or steps required by Section R310.2.1 shall be permitted. to encroach a maximum of 6 inches (152 mm) into the required dimensions of the window well. Bulkhead enclosures. Bulkhead enclosures shall provide direct access to the basement. The bulkhead enclosure' with the door panels in the fully open position shall provide the minimum net clear opening required by Section R310.1.1. Bulkhead enclosures shall also comply with Section R314.9. Bars, grills, covers, screens, or similar devices are permitted to be placed over emergency escape,and rescue openings, bulkhead enclosures, or window wells that serve such openings, provided the minimum net clear opening size complies with Sections R310.1.1 to R310.1.3, and such devices shall be releaseable or removable from the inside without the use of a key, tool or force greater than that which is required for normal operation of the escape and rescue opening.

Ladders or steps required by this section shall not be required to comply with Section R314 and R315.

Guard. Although the code does NOT specify requirements for guard around window wells to keep persons from falling into them, falls can and do occur. Because of the variations in size, location, and depth of window wells and since a guard could present an impediment to escape or rescue, the code is silent. The potential for falls into a window well should be evaluated by the homeowner and . suitable guards or visual barriers provide based on the location, depth and size of the well. Barriers, guards or covers installed to prevent falls must be placed in such away that does not impede use of the window well for escape and rescue. If covers are used, the effects of snow on the abifity to open or remove them in an emergency must also be evaluated. The ever - increasing concern for security, particularly in residential buildings has created a fairly large demand for security devices such as grilles, bars and steel shutters. Unless properly designed and constructed, these security. devices over emergency windows can completely defeat the purpose of the emergency escape and rescue window. The code makes provisions for use of security devices, . provided the release mechanism has been approved by the building official and it is operable from the.inside. without the use of a key or special knowledge. Fire deaths have been attributed to the inability of the individual to escape from the building because the security bars prevented emergency escape. Security devices sFiouid only be installed.where absolutely necessary and only with a permit after an evaluation by your local building and fire official: BCSO- GIO1210.04 3
