The state building code (780 CMR) requires that most residential dwellings have two means of egress, defined as unobstructed and constantly accessible exits to the exterior . This requirement As energy codes become more restrictive, requiring occupant sensing, daylight controls, and control of egress lighting, the application of photoluminescent lighting becomes more challenging. Means of egress stairways from balconies, galleries or press boxes as provided for in Section 1028.5.1 are not required to be enclosed. Proper arrangement of the means of egress ensures that exits are made available to occupants at all times and are located in the building where they can be accessed without traveling too far, for too long, or with the risk of the exits being compromised during an emergency.

This is the secondary means of egress that you would have to get to by going through a bedroom. If youre replacing a smaller window with a larger one that meets egress requirements, bear in mind that enlarging the height of the opening takes less structural work than enlarging the width. Such objects are limited to a 4 protrusion into circulation paths, but a 4 protrusion is allowed for handrails. The system capacity must be adequate to serve all the loads connected to the system simultaneously, or a load-shed system must be provided to maintain service to emergency loads by selectively disconnecting other loads (700.4(B)). Some manufacturers can install a special operator arm that allows the window to open wider than the standard bedroom window size operating arm to meet egress requirements. requirements in the ADA Standards (504).

The installation requirements for power systems serving emergency loads, including emergency lighting, appear in NEC Article 700, Emergency Systems. The IBC requires that doors providing access to areas of refuge be means of egress. Platform lifts, where permitted on an accessible means of egress, must have standby power (207.2). If a room is used as such, it must provide a means of escape. Sprinkler systems suppress or control fires, and also pinpoint their location, making response more efficient and timely. NEC 700 includes an additional requirement that the battery voltage remains at no less than 87.5% of its nominal voltage during the entire 90-minute period.

The number of people or occupant load for which the means of egress system must provide egress capacity is calculated per the requirements set forth in NFPA 1 or otherwise determined. landings. These meet egress requirements as long as you leave the "PUSH HERE" label in place. The AHJ should be consulted in advance of construction where a fuel cell system or alternative service is contemplated as the emergency supply. NFPA 99 specifically exempts the life safety branch from compliance with the fire-rating requirements of Article 700.10(D) under 6.4.2.2.1.6 and 6.5.2.2.1.5. A separate utility service may serve as the alternate source, where its reliability is acceptable to the AHJ as per 700.12(D). rollers, treads, and braking mechanisms that enable a person to be No, handrails and other elements cannot overlap door maneuvering To do this, there are some fundamental design concepts to follow to ensure that the means of egress is arranged for an exit to be reached by occupants in a safe and efficient manner. All egress doors shall be readily openable from the inside without the use of a tool, a key, or special knowledge or effort. Double-hung windows: Even when it's fully open, more than half of a double-hung window's overall area is blocked by glass. Various products are Means of egress design must consider the distance occupants travel to an exit, how far apart exits are located from one another, and the arrangement of the paths of travel within the means of egress. To be considered remote, the exits, exit accesses and exit discharges in new buildings must be located at a distance from one another not less than one-half (one-third if the building is fully sprinklered) the length of the maximum overall diagonal dimension of the building or area to be served, measured in a straight line between the nearest edge of the exits, exit accesses, or exit discharges. You skipped the table of contents section.

That solution might be suitable for utility spaces, where emergency light would provide wayfinding and be supplemented by portable battery-powered lamps. Given the IBCs ambiguity about emergency illumination in these areas, it is worthwhile to verify the AHJs interpretation of the code during design.
