EMERGENCY RULES
Effective Date of Rule: Immediately.
Purpose: To further extend the emergency declaration filed under WSR 10-22-051.
Citation of Existing Rules Affected by this Order: New section WAC 51-50-1005 and amending WAC 51-54-1000.
Statutory Authority for Adoption: Chapter 19.27 RCW.
Under RCW 34.05.350 the agency for good cause finds that immediate adoption, amendment, or repeal of a rule is necessary for the preservation of the public health, safety, or general welfare, and that observing the time requirements of notice and opportunity to comment upon adoption of a permanent rule would be contrary to the public interest.
Reasons for this Finding: The council finds that enforcement of the 2009 IBC section 1005 Egress Width would be extremely problematic and cause extensive confusion in the application of the building code statewide. The exception provided in the emergency rule makes the requirement consistent with the latest standard for health and safety. Enforcing the code as published in 2009 would require building designs to meet a significantly expanded prescriptive width requirement. The design changes would result in a period of time in which buildings use a radically different egress system, resulting in major economic impacts for building owners and designers and confusion resulting in a lack of compliance compromising public health and safety. The latest code as adopted by the International Code Council for publication in 2012 requires alternative safety systems which provide greater safety without radical and costly design changes. The council has adopted a permanent rule to be effective after the 2011 legislative session per RCW 19.27.074.

Section 1005 -- Egress width.
1005.1 Minimum required egress width. The means of egress
width shall not be less than required by this section. The
total width of means of egress in inches (mm) shall not be
