of the risk well before it becomes an emergency. By law, this cannot be called an alarm, thus the name "low level CO monitor". While different manufacturers have varying levels of notification, ideally it will have some warning at 10 PPM. This lower level warning will allow time for a professional to come and find the cause. While people often blame the furnace, it can also be a water heater, fireplace, unvented stove, oven, or even an attached garage. Yes, even an all electric house can suffer from an unhealthy level of CO just by backing a car in or out of the garage. It is important for the source to be identified and corrected although sometimes the source can be misleading such as a golf cart charger. I recommend anyone in the trades or even on a camping trip to also carry a personal low level CO monitor. This will notify the worker when they are entering a potentially hazardous situation. One time mine went off in the summer when I was brazing an evaporator in a walk in cooler. Someone had closed the door while I was working, but my personal low level monitor alerted me to the hazard. When I started in the trade, wearing PPE such as gloves and safety glasses where not as common but now considered common sense. I hope having low level CO monitors in homes, businesses and on person becomes just as common. To learn more, I recommend reading " Carbon monoxide: a clear and present danger" by Bob Dwyer HVAC E learn network has an online course for CO and combustion analysis https://hvacr.elearn.network/courses/c ombustion-analysis
