The Consumer Product Safety Commission (CPSC) is warning consumers to stop using a carbon monoxide (CO) detector sold on Amazon because it can fail to detect the presence of the gas. Sensitivity tests found that the HECOPRO digital display CO detector sold on Amazon.com did not set off an alert when exposed to concentrations of carbon monoxide Press the Test Button: Locate the test button on your Kidde carbon monoxide detector. It is usually marked with the word “Test” or an image of a bell. Press and hold the test button for a few seconds until you hear a loud alarm sound. This will simulate an actual carbon monoxide alarm. 3. How carbon monoxide detectors work. A carbon monoxide detector watches for dangerous levels of carbon monoxide in the air. The gas is measured in parts per million (ppm). While most people won’t Carbon monoxide detectors work by using sensors to detect the presence of CO in the air. When CO levels reach a certain threshold, the detector sounds an alarm to alert occupants of the building Carbon monoxide detectors, also known as CO detectors, are devices designed to monitor the levels of carbon monoxide in the environment. They work by detecting the presence of CO and sounding an alarm when concentrations reach dangerous levels. Insert the screws provided until head is approx. 1/8 inch (3 mm) from wall (if mounting in plaster board or drywall, drill 3/16 inch (5. mm) hole and use plastic anchor provided). 4. Hook the Alarm over the screw onto the keyhole in back of unit. 5. Plug power cord into AC outlet. Carbon monoxide levels are rising. This Heads-Upwill occur if carbon monoxide levels stay at 70ppm for 60-240 minutes. The smoke in the room has reached emergency levels. The carbon monoxide in the room has now reached emergency levels. “READY. PRESS TO TEST.” “HEADS-UP. THERE’S SMOKE IN THE (ROOM NAME). THE ALARM MAY SOUND.” “HEADS-UP. Just press the test button and the alarm should sound. If it’s a battery-powered alarm and doesn’t sound off, change the battery and retest it. If it’s a hardwired unit and doesn’t work, replace it immediately. If they do sound off, check the date on the label so you’ll know when to schedule replacements. Smoke detectors are good for boilers. kilns. heaters. Processes, such as welding, foundries, coke ovens and metal hardening, can also be a source of carbon monoxide exposure. Carbon monoxide tends to build up in pockets, in poorly ventilated areas of workplaces. This can happen even in semi-enclosed workplaces, where tarps and plastic sheeting are used for shelter. Carbon monoxide detectors are cheap and easy to install in any area of the workplace. Symptoms of Carbon Monoxide Poisoning at Work In the early stages of carbon monoxide poisoning, you might start to experience non-specific symptoms which can vary from person to person. ZB8utyL.
