A series of proposals by the National Institute of Standards and Technology (NIST) that target much more stringent structural, fire protection, and egress requirements
. Among these changes is a proposal to require a "total content burnout" threshold for progressive-collapse-prevention design.
In fire safety, the new Codes expand sprinkler and egress requirements
and they enhance the design of standpipe systems in high-rise buildings.
Tunnel egress requirements
, provisions for the evacuation of the disabled (which vary by international jurisdiction), and requirements for evacuation from "back of house" spaces are also not addressed.
Such a cluster would have to be at least 54in (137cm) from the wall to properly accommodate passenger comfort and egress requirements
. What is more, two of the BAC occupants would have to face the wall -- an uninviting consequence, indeed.
sliding window to meet the minimum egress requirements
"With new construction, you might be talking about maybe doing a little additional site work, like leveling something out, or maybe adding some more fill to bring the building into compliance with egress requirements
," Pearsall says.
This change was also opposed by the ICC technical committees with oversight of egress requirements
in the ICC codes.
wide does not meet egress requirements, since its net clear opening is only 3.33 sq.
Window manufacturers list the net free opening of their windows and skylights in their catalogs, and whether they meet egress requirements.
But if you live in an older, "pre-owned" home, open your windows fully, pull out a tape measure and see if the opening meets current egress requirements. Multiply the width by the height of the opening to determine whether it's the required 5.7 sq.
As you remodel, you'll want new egress windows that match the style of the existing windows and meet egress requirements. This can be a challenge.
Some manufacturers can install a special operator arm that allows the window to open wider than the standard operating arm to meet egress requirements. Others have an operator arm that can be pushed to open the window wider in an emergency.
