The Trade Inspection verified 167 carbon monoxide detectors offered by 84 companies.

Over 25 per cent of them are mislabeled. One of the detectors tested posed a real danger it did not alarm when carbon monoxide was leaking.
Carbon monoxide is a highly poisonous gas, known as the "silent killer". It is colourless, odourless and tasteless which is why it is so difficult to detect on one's own. Lack of periodic inspections of chimney and ventilation ducts, faulty heating devices or their improper operation can cause serious poisoning or even death.
Therefore, it is important to remember to install carbon monoxide detectors in rooms to warn you of the danger in time.
The Trade Inspection examined 167 detector models.
Most irregularities were related to labeling and instructions for use. They lacked, among other things, markings and warnings important for consumers, e.g. the maximum time the device can be used or that the detector must be installed by a professional.
16 detector models underwent testing in a specialised laboratory.
Experts tested whether at a high alarm threshold of 300 ppm CO (parts per million the number of CO molecules in 1 million air molecules) the alarm is triggered in a timely manner. It should turn on within three minutes.
During testing, one detector model did not work. The inspection resulted in twelve post inspection statements and one administrative proceeding. The defective detector was withdrawn from the store and the trader removed the causes of the irregularity and repaired the product.
Compared to previous detector inspections, the number of irregularities detected is lower. Previously, samples of 7 models of carbon monoxide detectors were referred for laboratory testing, all of which were questioned due to improper triggering of alarm thresholds.
Remember:
• The detector is not a substitute for proper heater installation and maintenance. Periodic inspection, maintenance and flue repairs are also necessary.
• Do not block vents or seal windows in rooms with appliances that can emit carbon monoxide. Open the windows in such rooms regularly.
• Call a professional to install the detector.
• If the alarm sounds, it is important to find and remove the source of the increased CO emissions. The cause could be, for example, a faulty connection of the heater to the chimney. ■
