CO Poses Risks for Boaters

Dealer 5 Year Replacement Sheet

All Carbon Monoxide Alarms that are 5 years old and older are beyond their Mandatory Replacement Time and MUST be replaced. Underwriters’ Laboratories (UL® Carbon Monoxide Standard UL 2034) now require that all Carbon Monoxide Alarms be designed to include an End of Life signal. ALL Safe-T-Alert Carbon Monoxide Alarms over five (5) years old on recreational boats MUST be replaced.

If the detector is over 5 years old on a boat you are inspecting, recommend replacement or have the owner sign this notice.

Safe-T-Alert Sounds the Alarm on Old Carbon Monoxide (CO) Detectors

Many boaters believe, since their boat came with a CO detector, they are good to go but that might not be the case as the detectors have a much shorter lifespan than the boats do. CO detectors first came to the market in the 1980s and some of those original detectors are still installed on older boats that are currently up for sale. So, Safe-T-Alert is encouraging every boater, dealer and surveyor to “Check the Alarm” and replace any detector with an on/off switch or a “plug-in connector” on the circuit board. If it does not have either of those, then check the date code on the unit and replace anything that has been used for more than five years.

MTI recommends replacing all Safe-T-Alert™ alarms with model numbers: SA-4, SA-5, 50-541/542 and 60-541/542. These model numbers were designed in the 1980s or 1990s and have all exceeded their useful life.

Dealers and Surveyors should also recommend replacement of CO detectors from the following brands that have been out of production for decades: Aqua Meter, Asahi, and NewTec. Also be aware that Fireboy-Xintex, Inc., model CMD-4 has been discontinued.

For those replacing older or larger alarms, MTI offers oversized “legacy” cases, that will cover and/or fit most of the old alarm installations.
