Do you know the hazards of carbon monoxide? Carbon monoxide (CO) is a colorless, odorless gas and a toxic pollutant. It is highly toxic to the blood and the nervous system. Normally, the oxygen entering the bloodstream through the respiratory system will bind to hemoglobin (hb), forming oxyhemoglobin (o2hb) which is transported to various organs and tissues of the body and involved in normal metabolic activity. For example, if the concentration of carbon monoxide in the air is too high, much of the carbon monoxide will enter the body`s bloodstream. The degree of harm of carbon monoxide to the body mainly depends on the concentration of carbon monoxide in the air and the length of time that the body absorbs carbon monoxide. For example, if the concentration of carbon monoxide reaches 30ppm, the level of carboxyhemoglobin (cohb) in human blood reaches about 5%, which can lead to visual and hearing impairment. When the amount of carboxyhemoglobin (cohb) in blood reaches more than 10%, the body will be severely damaged and cause adverse reactions such as headache, dizziness, nausea, chest tightness, fatigue, confusion, etc. What are the hazards of carbon monoxide? Carbon monoxide poisoning can also cause serious damage to our hearts. When the cohb reached more than 5%, coronary blood flow increased significantly; when cohb reached 10%,

Where should gas leak detector be installed and how to install it? In our real life, the use of gas has been very common, of course, gas is also more dangerous, many people in order to ensure the safety of themselves and their families, choose to use gas alarm, when gas leakage, gas alarm will be timely alarm. So where should the gas alarm be installed and how to install it? 1. The installation position should keep horizontal distance between 1 ~ 2 m with such gas leakage source, like kitchen gas stove or gas water heater. 2. Detect natural gas and artificial coal gas: Installation height from the ceiling is not more than 30 cm 3. Detection of liquefied petroleum gas (LPG): Installation height from the ground is not more than 30 cm

Photoelectric smoke alarm's work principle is to use its internal optical maze, equipped with infrared tube. When the environment is smokeless, the infrared receiving tube cannot receive the infrared light emitted by the infrared transmitting tube. When the smoke enters the optical maze, the receiving tube receives the infrared light through refraction and reflection and converts it into an electrical signal. The detection circuit amplifies the electrical signal and sends an alarm when the concentration exceeds the set threshold. The volume of smoke particles generated by smouldering fire is relatively large, and the larger smoke particles diffuse light more strongly. In this case, the photoelectric smoke alarm will alarm before the ion smoke alarm. For example, a fire in a house usually produces a lot of smoke in the initial stage. It is recommended to install a photoelectric smoke alarm in such places.

A "smoke alarm" is made up of two parts: a sensor used to detect smoke and a loud buzzer that can alert people in case of danger. A 9v battery is all you need to keep a smoke alarm running. Today, the most commonly used smoke detectors in the world should be photoelectric smoke detector and ionization smoke detector. Some people ask: Is it useful to install smoke alarms? With the increase of modern family fire and electricity consumption, the frequency of family fire is getting higher and higher. Once a family fire occurs, it is easy to have adverse factors such as not timely fighting, lack of fire extinguishing equipment, and people in the scene panic, slow escape and so on, which ultimately lead to great loss of life and property. The main cause of home fires is carelessness and failure to take preventive measures in time.
