What Is a Fire Alarm Cover?

With the increase of fire and electricity consumption in modern homes, the frequency of home fires is getting higher and higher. Once a home fire occurs, it is easy to appear unfavourable factors such as untimely extinguishing, lack of fire extinguishing equipment, panic among the people present, and slow escape, which will eventually lead to major loss of life and property. To discuss the characteristics of home fires and fire prevention countermeasures has practical significance for preventing home fires and reducing fire losses.

Fire alarm

With the increase of fire and electricity consumption in modern homes, the frequency of home fires is getting higher and higher. Once a home fire occurs, it is easy to extinguish the fire in a timely manner,

It has practical significance for preventing domestic fires and reducing fire losses

In modern urban homes, many people cause fire accidents because they do not understand the common sense of family safety. The happy families are destroyed in an instant, and some of them lead to the destruction of their homes. In the event of a residential fire, improper disposal and delay in alarming cause personnel Therefore, people should actively understand the main causes of home fires, master the knowledge of preventing fires and protect themselves in case of fires, and eliminate them in time.

Every year, there are more than 50,000 serious family fires in the UK. Most of these fires cause casualties and major family property losses.

The main cause of family fires is paralysis, and preventive measures are not taken in a timely manner

Precautions

When calling the fire alarm "119", be calm and calm. The key is to make the situation clear and concise.

Society is a group of citizens. Social wealth is wealth created and owned by citizens. Public fire protection facilities are fire extinguishers and equipment set up to extinguish fires. Protecting social wealth and maintaining public facilities is the responsibility of citizens: each citizen must carefully abide by fire protection regulations and fulfill the fire safety duties assigned by the law. Only in this way can social wealth be protected from fire hazards and public fire protection facilities from being damaged. .

Civic Fire Safety Responsibility

I. Learn and master scientific knowledge on fire prevention, strictly abide by fire protection laws and regulations, and actively do a good job in fire safety.

2. Voluntarily protect fire-fighting facilities from damage, misappropriation, dismantling, and deactivation of fire-fighting facilities, without burying pressure, enclosing fire hydrants, occupying fire prevention distances, and not blocking fire passages.

3. Do not bring any kind of flame into the production and storage of flammable and explosive dangerous crystal sites, do not bring flammable and explosive dangerous articles into public places or take public transportation.

4. The fire alarm should be reported immediately after the fire; private communication tools should facilitate the fire alarm without compensation; do not lie about reporting the fire alarm

5. Adult citizens have the obligation to participate in organized fire fighting.
