Nov. 25, 2002: CO Detector Discussion Re-enters ASHRAE Meeting Schedule

November 24, 2002
ATLANTA, GA — The reliability of CO detectors and the American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE’s) proposed residential ventilation standard will be discussed in a special session the day before the Society’s 2003 Winter Meeting is slated to begin in Chicago, IL, Jan. 25-29, 2003.

The session will be held at 2 p.m. Friday, Jan. 24, at the Palmer House Hilton, hosted by the committee developing proposed Standard 62.2P, “Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings.”

“Parties who have previously shown interest in the topic have been invited,” stated the society, “and the session is open to other interested parties as well.”

At various times in its preparation, the proposed standard has included a requirement that CO alarm devices be installed in all residences. The current draft, recently released for its fourth public review, does not contain the requirement.

The requirement was removed after the standard’s first public review, when commentors questioned the reliability and expense of alarms, and stated that these devices aren’t needed if there are requirements regarding CO sources, according to committee chair Max Sherman. “Keeping this issue in mind, the committee looked carefully at air handlers, excessively large exhaust fans, and unvented combustion devices,” Sherman said.

In the second public review, the committee received many comments requesting that the requirement be returned to the standard, he continued.

The committee held a public meeting in December 2001 to discuss the recommendation. Members rejected requests to return the requirement to the proposed standard based on reports questioning the reliability of devices currently in the marketplace.

“To partially accommodate commentors on both sides of the issue, the committee did not include device requirements in the current draft, but agreed to reopen the issue when the CO alarm industry could demonstrate a more reliable set of products,” said David Grimsrud, who will chair the session. He is chair of the committee’s IAQ subcommittee.

The committee recently was contacted by the CO alarm industry with information that new, reliable devices are now available in the marketplace. “Accordingly, we have scheduled a special session to hear the new information and let interested parties comment on it,” Grimsrud said.
