Furnace Safety Inspection – Carbon Monoxide

Having a Carbon Monoxide Alarm is essential, but do not rely solely on this as your best defense against the dangers of Carbon Monoxide exposure. Learn why below.

Store-bought carbon monoxide alarms (all UL-Approved) will not protect you from low-level carbon monoxide poisoning because their sensors are not designed to alarm until you have been exposed to CO at a level of 70 parts per million (ppm) or above for up to 3.5 hours.

Why Is It A Problem?

  • The World Health Organization says that levels above 9 ppm can cause low-level CO poisoning with symptoms.
  • OSHA regulations prohibit employees from working in any level above 35 ppm for longer than 8 hours.
  • Outside air is regulated at a limit of 9 ppm for 8 hours (or a maximum of 35 ppm for one hour) by U.S. National Ambient Air Quality Standards.

Despite the recognized danger of these lower-levels of CO, UL-Listed CO alarms are prohibited from sounding an alarm for any level below 70 ppm. This rule was adopted to avoid “nuisance calls” from alarms from low-level exposure to emergency call centers rather than impose safe standards on the air in our living spaces. Because of this inherent danger, UL-Approved CO alarms specify in their instructions that they are only suitable for most healthy adults. UL-Listed CO alarms are not suitable for children, the pregnant, and the elderly, those with heart ailments, breathing problems or other health issues.

Most UL-Listed CO alarms fail to provide protection even for the 70 ppm due to improper installation. If one of these CO alarms is plugged into an outlet at knee level on the first floor, the alarm will not sound until CO levels are much higher. CO alarms MUST be installed at eye-level to work properly. CO is lighter than air, so it rises. Harmless carbon dioxide sits at knee-level.
