The project shall comply with these requirements. SECTION 604 MEANS OF EGRESS 604.1 General. Alterations shall be done in a manner that maintains the level of protection provided for the means of egress, and in accordance with section 102.2.2.1. COMMENTARY: Based upon this section and Section 603 the following is required. Existing Stairway and Egress from the Upper Floor The upper ﬂoor is accessed from an interior circular stairway (enclosed in a two story space) on the south west corner, adjacent to an exterior door. A second interior stairway interconnecting the upper ﬂoor and the manufactur- ing area below is located at the north wall of the upper ﬂoor ofﬁce/employee area and is not enclosed and re- quires passage through the factory. The upper ﬂoor is not accessible (521 CMR) to the public. The Upper ﬂoor is for employee use only. The occupant load is as follows. Upper level: Mezzanine Storage (687 sf) @ 300 sf gross = 3 Employee/Ofﬁce Area (2968 sf) @ 100 sf gross = 30 Ground ﬂoor: Employee/Ofﬁce Area (1001 sf) @ 100 sf gross =11 Manufacturing Area (17,073 sf) @ 100 sf gross = 171 A spiral stairway is not permitted (1009.9) for this use as a component in the means of egress. Stairway 2 does not meet the requirements (1009) of a means of egress. According to the Code there is currently no legal egress from the upper ﬂoor. COMMENTARY: Two new means of egress from the upper ﬂoor will be required. Egress from the Ground Floor The occupancy load of the ground ﬂoor (by Code) is 182 persons. This assumes that the occupancy load from the upper ﬂoor is not added because the upper ﬂoor will have direct access to the exterior. This level currently has 252 inches of egress width. Calculations for exits capacity: 252 inches/.2 = 1260 persons capacity. Exits are adequate for width. Distance to exits: existing maximum distance to an exit is approximately 100 ft. Allowed: Table 1016.1, 300 ft. The Shelburne Architects is a Full Service Architectural Firm Serving MA, VT, CT, & NH. Page of 11 17 When the sprinkler system is installed the allowable distance to exits increases to 400 ft. Exit lighting and emergency lighting and door hardware is inadequate and will be corrected as part of the draw- ings provided for the building permit application for the proposed addition. COMMENTARY: There is NO problem with exit capacity or distance to exits. SECTION 605 ACCESSIBILITY 605.1 General. Accessibility requirements shall be in accordance with 521 CMR.
