NFPA Update
Karen Hall, National Hydrogen
Association
NFPA VAF Committee, which is responsible for NFPA
52, has been busy reviewing documents. There are two basic areas for consideration.
They include three Technical Ballots for proposed Tentative Interim Amendments
(TIAs) to NFPA 52, and an issue regarding the scope of committees.
The
three technical issues were balloted on their merits as well as to whether the
change is an emergency. VAF Committee members were asked to return their ballots
on or before January 6. At the time of publication, the results of the balloting
had not been announced.
TIA 834 is to amend annex information to provide
information that was previously unknown regarding containment of spilled liquid
hydrogen.
TIA 835 is to address the issue of product liability for aftermarket
installations of other fuel systems when OEMS do not provide approval or supporting
documentation.
TIA 836 is to require all dispensing and storage of LNG
including mobile refueling into vehicle onboard fuel systems to comply with requirements
of a permanent LNG refueling installation at the point of storage and dispensing
fuel.
At the October 2005 meeting, the NFPA Standards Council considered
the request of Mr. St. Clair, Chair, TC on Industrial & Medical Gases, for
clarification of several TC scopes which appear to be overlapping in the area
of bulk industrial and medical gases. This request was circulated to the affected
TCs including Vehicular Alternative Fuel Systems (VAF), Health Care Facilities
Gas Delivery Equipment (HEA-GAS) and Piping Systems (HEA-PIP), and Cleanrooms
(CLR).
After reviewing the responses received, the Council voted to accept
in principle the scope changes as recommended by Mr. St. Clair. Final action,
however, is deferred until the Council's March 21-22, 2006 meeting, at which time
any final recommended modifications will be considered.
The Vehicular Alternative
Fuels technical committee will have their next meeting on May 9 & 10, 2006
at Sandia National Laboratories in Livermore, CA. Livermore, CA is This meeting
will be a planning meeting for the next edition of NFPA 52 Vehicular Fuel Systems
Code.
