New CO Regulations

September 3, 2017 is the deadline set by the New Jersey Department of Community Affairs by which carbon monoxide “CO” detectors must be installed in any building where there is a fuel-burning appliance or an attached garage. Make sure your location is compliant.

  • The detectors may be battery operated, hard-wired or of the plug-in type. They must:
  • Be installed in the immediate vicinity of all potential sources of carbon monoxide
  • Have a distinct visual and audible signal
  • Bear the label of a nationally recognized testing laboratory such as Underwriters Laboratory “UL” and be tested and compliant with UL standard 2034

If you choose to install a carbon monoxide alarm instead of a detector, it must:

  • Be placed where the audible signal is not less than 15 decibels above the average ambient sound level
  • Be installed in the immediate vicinity of all potential sources of carbon monoxide

Although no guidelines were issued on placement distance from a source of combustion, it is recommended that the device be placed within 6 feet, if possible.

The Diocese has purchased a large quantity of 10-year-life, sealed-battery, UL-certified, wall-mounted units that comply with the detector specifications issued by the Department of Community Affairs. Barbara Mullaney is taking orders for detectors from parishes and schools. If assistance is needed to install detectors, please let Barbara know when you place your order. Barbara can be reached by telephone: 609-403-7163 or via email: This email address is being protected from spambots. You need JavaScript enabled to view it..

Take some time to walk through your school/parish property, including all outbuildings, and make note of the areas which will need a carbon monoxide detector or alarm.

If the building is a residence, such as a rectory or convent, a CO detector should also be placed at the top of each stairway in multistory buildings. 

While conducting this inspection, you may also want to ensure that there are adequate smoke alarms in place and the batteries (if applicable) are fresh. Complying with these new regulations is not only legally required, it makes good sense for the protection of those whom we serve.

Should you have any questions or concerns about complying with this new state requirement, please contact Joseph Cahill, Director of Risk Management.
