The product is safe and does not pose a threat to the life or health of consumers.
Product tests were carried out by the Institute of Innovative Technologies EMAG in Katowice, commissioned by the President of the Office of Competition and Consumer Protection. The results of the inspection were presented in the letter of the Mazowieckie Provincial Inspector of Trade Inspection in Warsaw, No. DS.8361.160.2015
ATTENTION!!!
In order to maintain the proper functioning of the device, the device should be regularly tested at least once a week.

The useful life of the CO detector device
The average service life of the device (electronic sensor) is approximately 5 years. This time is strictly dependent on the environmental conditions in which the device was operated, production date, number of alarm activations, etc.). It is recommended to regularly replace old models with new ones.
TIPS RELATED TO SAFETY
To minimize the risk of carbon monoxide CO, have qualified specialists regularly (at least once a year) inspect the heating system, ventilation system, chimneys and exhaust gases from fuel-powered appliances. All heating devices should always be installed in accordance with the manufacturer's recommendations and local building codes. All devices should be installed and checked by specialists after installation. Regularly check the connections of the fuel supply or exhaust pipes for any leaks, cracks, rust marks etc. Also pay attention to the color of the flame on the burners (yellow or orange color may be a symptom of incomplete combustion of the fuel). It is absolutely necessary to familiarize all household members with the alarm devices used in the installation.

Symptoms of Carbon Monoxide (CO) Poisoning
Carbon monoxide (CO) is a highly poisonous gas that is odorless and colorless. It is formed as a result of incomplete combustion of fuels and is extremely dangerous for all living organisms. In the event of exposure to carbon monoxide and symptoms of poisoning, it is imperative to see a doctor as soon as possible.
- Mild exposure: Mild headache, nausea, vomiting, fatigue (often described as "flu-like" symptoms).
- Moderate exposure: Severe headache (pulsating), drowsiness, light headedness.
- Extreme exposure: Unconsciousness, convulsions, cardiac failure, death.
The above exposure levels are for healthy adults. For children, the elderly or those with health problems, the risk is much higher.

Features of the carbon monoxide detector
