The following Tentative Interim Amendments (TIAs) have been proposed to NFPA. They are being published for public review and comment. Comments should be filed with the Secretary, Stan-dards Council, by the date indicated below.
These proposed TIAs have also been forwarded to the responsible technical committee for processing. The technical committee will consider public comments received by the date indicated below before vote is taken on the proposed TIA. (Please identify the number of the TIA to which the comment is addressed.) Three-fourths of the voting members of the technical committee and/or the technical correlating committee, if any, must vote in favor of the TIA on both technical merit and emergency nature as calculated in accordance with 3.3.4.5 of the Regulations Governing Commit-tee Projects to establish a recommendation for approval of the TIA.
The Standards Council will review the technical committees’ bal-lot results, the public comments, and any other information that has been submitted when it considers the issuance of the TIA at its March 3–4, 2009 meeting. In accordance with 1.6.2(c) of the Regulations, a proposed TIA which has been submitted for pro-cessing pursuant to 5.1 of the Regulations will be automatically docketed as an appeal on the agenda of the Standards Council, and any party may advocate their position either in writing or in person before the Council. If an automatically docketed appeal has not been pursued by any party, the Council need not consider the mat-ter as an appeal.
A TIA is tentative because it has not been processed through the entire codes- and standards-making procedures. It is interim because it is effective only between editions of the document. A TIA automatically becomes a proposal of the proponent for the next edition of the document. As such, it then is subject to all of the procedures of the codes- and standards-making process.
NFPA 58-2008
Liquefied Petroleum Gas Code
TIA Log No.: 939
Reference: 6.8.1.1
Comment Closing Date: December 16, 2008
Submitter: Technical Committee on Liquefied Petroleum Gases
1. Revise 6.8.1.1 to read:
6.8.1.1一期或高压regulators shall be directly attached or attached by flexible connectors to the vapor service valve of a container, or to a vaporizer outlet, or to interconnecting piping of manifolded containers or vaporizers.
6.8.1.1 First-stage or high-pressure regulators shall be directly attached, or attached by flexible metallic connectors, to the vapor service valve used on stationary (permanent) container installa-tions, and to interconnecting piping of manifolded stationary (per-manent) container installations, or to a vaporizer outlet.
Submitter’s Substantiation:This will change the text back to the text in the 2004 edition. It has become apparent that the change is preventing some products from being used that were previously allowed by the code and was available.
Emergency Nature:This recognizes that a change was made in the 2008 edition which, inadvertently, had an effect that was not anticipated.
NFPA 86-2007
Standard for Ovens and Furnaces
TIA Log No.: 940
Reference: 8.2.9
Comment Closing Date: December 16, 2008
Submitter: Ted Jablkowski, North American Manufacturing Company
1. Add a new subsection 8.2.9 to read as follows:
8.2.9Shutdown of the heating system by any safety feature or safety device shall require manual intervention of an operator for re-establishment of the normal operation of the system.
Submitter’s Substantiation:The suggested text for addition is directly from subsection 1. 7.2.4 of NFPA 86, 2003 edition.
2. In adding paragraph 8.3.1.2 in the 2007 edition, the definition of Safety Shutdown was not also added to the 2007 edition due to a clerical oversight on the part of the Technical Committee.
3. Without the definition of Safety Shutdown, the requirement for “manual intervention” was lost in the 2007 edition. This was not the intent of the Technical Committee.Adding the definition of Safety Shutdown can be done in the 2010 edition.
4. However, it is not appropriate to add a requirement like “manual intervention” only in a definition. The requirement should be in the mandatory text as proposed herein.
Emergency Nature:There have been questions to the NFPA 86 staff liaison and TC members about this topic. The Technical Committee reviewed this matter at their May 2008 meeting and instructed the submittal of a TIA to address this oversight. Operat-ing without manual intervention following a safety shutdown can result in an unsafe condition.
