[. . . ] Continued · USER'S MANUAL BATTERY OPERATED CARBON MONOXIDE ALARM WITH SILENCE FEATURE This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician. HOW YOUR CO ALARM WORKS GENERAL INFORMATION · This Co Alarm does not operate without a working battery. [. . . ] These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane. Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real danger now that homes are more energy efficient. "Air-tight" homes with added insulation, sealed windows, and other weatherproofing can "trap" CO inside. 3 SYMPTOMS OF CO POISONING These symptoms are related to CO POISONING and should be discussed with ALL household members. Mild Exposure: Slight headache, nausea, vomiting, fatigue ("flu-like" symptoms). Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate. Extreme Exposure: Convulsions, unconsciousness, heart and lung failure. Exposure to carbon monoxide can cause brain damage, death. Some individuals are more sensitive to CO than others, including people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be more quickly and severely affected by CO. Members of sensitive populations should consult their doctors for advice on taking additional precautions. The following conditions can result in transient CO situations: 1. Excessive spillage or reverse venting of fuel appliances caused by outdoor conditions such as: · Wind direction and/or velocity, including high, gusty winds. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). · Negative pressure differential resulting from the use of exhaust fans. · Several appliances running at the same time competing for limited fresh air. · Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters. · Obstructions in or unconventional vent pipe designs which can amplify the above situations. Extended operation of unvented fuel burning devices (range, oven, fireplace). Temperature inversions, which can trap exhaust close to the ground. Car idling in an open or closed attached garage, or near a home. These conditions are dangerous because they can trap exhaust in your home. Since these conditions can come and go, they are also hard to recreate during a CO investigation. FINDING THE SOURCE OF CO AFTER AN ALARM Carbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after an alarm. [. . . ] If not, press the Test/Silence button again and keep ventilating your home. If frequent alarms continue, have home rechecked for potential CO problems. You may be experiencing an intermittent CO problem. CO levels indicate a potentially dangerous situation. CO Alarm sounds frequently even though no high levels of CO are revealed in an investigation. The CO Alarm may be improperly located. Refer to "Where to Install CO Alarms. " *For a list of acceptable replacement batteries, see "Page 4: Regular Maintenance.
