A look at a few carbon monoxide alarm standards
U.L. 2034 and CSA 6.19 (United States & Canada)
· 30 PPM CO and under, no visual display allowed,
· 30+ PPM CO – 70 PPM visual display allowed, no alarm test point
· 70+ PPM CO and under 150 PPM of CO; test point, resist one hour but must alarm in four hours.
· 150+ PPM CO and under 400 PPM of CO; test point, resist alarming for 10 minutes but must alarm before 50 minutes.
· 400+ PPM CO and higher; test point, resist alarming for four minutes but must alarm before 15 minutes.
The European Standard - EN50291 For Carbon Monoxide Alarms
· 30 PPM CO, the alarm must resist for at least 120 minutes when over this level
· 50 PPM CO, the alarm must resist for the first 60 minutes but must activate before 90 minutes
· 100 PPM CO, the alarm must resist for the first 10 minutes but must activate before 40 minutes
· 300 PPM CO, the alarm must activate within 3 minutes
There are some safety benefits in the European Standard - EN50291 For Carbon Monoxide Alarms over the U.L. 2034 and CSA 6.19 Standards for Carbon Monoxide Alarms include:
· Permitted to visually display any level of CO (U.L. & CSA listed units are not allowed to display under 30 PPM)
· Allowed to alarm above 30 PPM if level remains after 2 hours
· Near immediate warnings (immediate detection & response) are permitted above 300 PPM. (U.L. & CSA listed units must resist alarming for 10 minutes, but must alarm after one hour.)
If you are of vulnerable health or don't want to be and require protection at levels not supplied by the alarms criteria listed above, please note the criteria of an alarm type that will alert you to lower levels of the poison, and before you would begin to experience health consequences.
The following is a description of the digital display and audible response information on the CO Experts low level CO alarm, with an acid based electrochemical sensor technology. These visual and alarm announcements are in real time. There is no waiting period; the alarm sounds when these levels are reached.
· 0-6 PPM CO No warnings; no display, no alarm
· 7+ PPM
CO Visual display of PPM concentration changes
· 10-24 PPM CO One series of beeps [4+4+4+] – once every 60 seconds
· 25-34 PPM CO - One series of beep sequence every 30 seconds
· 35-49 PPM CO - One series of beep sequence every 20 seconds
· 50-69 PPM CO - One series of beep sequence every 10 seconds
· 70 PPM & HI - One series of beep sequence every 6 seconds
· HI - HI means goodbye, get out, what are you still doing here?
This unit does not display anything but HI when the concentration is over 70 PPM CO.
There are news stories found within the archives of this blog that reveal the following list of symptoms and some others, were experienced by those victims who were glad they had a carbon monoxide alarm that alerted them to the poisoning, but note that there were illness symptoms experienced prior to the alarm sounding, anywhere from hours, to months, to years. Please reference Carbon Monoxide Survivor.
Don’t ignore those symptoms of carbon monoxide poisoning that include headache, confusion, nausea, depression, weakness, light-headedness, shortness of breath, heart distresses and vomiting. Ask to be tested for carbon monoxide poisoning. These are some of the known symptoms.
Protect yourself and others from CO poisoning after you decide when you’d like to begin protection. Bob Dwyer, CSME Carbon Monoxide Safety
