What is the difference between fire-fighting facilities and fire-fighting equipment?
There are differences in functions and uses between fire-fighting facilities and fire-fighting equipment. Fire-fighting equipment refers to equipment used for fire extinguishing, fire prevention and fire accidents, including fire extinguishers, fire hydrants, water hoses, water guns, demolition tools, etc. Fire protection facilities refer to automatic fire alarm systems, fire hydrant systems, automatic fire extinguishing systems, smoke prevention and exhaust systems, emergency broadcasting, emergency lighting, and safe evacuation facilities. Although fire-fighting facilities an
How to operate explosion-proof tanks
Explosion-proof tanks are important equipment that can effectively protect against the shock waves and fragments generated when explosives explode, as well as the damage caused by surrounding people. It has been widely used in explosion-proof safety inspections such as armed police, public security, civil aviation, customs, and ports. department. Today I will introduce to you how to operate an explosion-proof tank. 1. After transporting the explosion-proof tank to the destination, open the lid and put the explosion-proof tank into working condition.
carbon dioxide fire extinguisher
Carbon dioxide fire extinguishing agent is a fire extinguishing agent with a history of more than 100 years. It is cheap, easy to obtain and prepare. It mainly relies on suffocation and partial cooling to extinguish fires. Carbon dioxide has a higher density, about 1.5 times that of air. Under normal pressure, liquid carbon dioxide will vaporize immediately. Generally, 1kg of liquid carbon dioxide can produce about 0.5 cubic meters of gas. Therefore, when extinguishing a fire, carbon dioxide gas can exclude air and surround the surface of burning objects or be distributed in a relativel
Precautions for trolley-type dry powder fire extinguishers
When using a carbon dioxide fire extinguisher, if it is used outdoors, you should choose to spray in the upwind direction, and place your hand on the wooden handle of the cylinder to prevent frostbite. If it is used in a small space indoors or outdoors, the operator should leave quickly after extinguishing the fire to prevent suffocation. Cart-type dry powder fire extinguishers and portable dry powder fire extinguishers are suitable for fires and how to use them: Sodium bicarbonate dry powder fire extinguisher is suitable for initial fires of flammable and combustible liquids, ga
Trolley type dry powder fire extinguisher
The trolley storage pressure ABC dry powder fire extinguisher is equipped with ammonium phosphate dry powder fire extinguishing agent and nitrogen. It is suitable for extinguishing initial fires of flammable solids, flammable liquids, flammable gases and electrical equipment. Widely used in factories, warehouses, ships, gas stations, distribution rooms, vehicles and other factories. Cart-type carbon dioxide fire extinguishers are generally operated by two people. When using them, two people push or pull the fire extinguisher to the burning place, stop it about 10 meters away from the bu
Analysis of the working principle of wet fire extinguishers
1. Overview of wet fire extinguishers Wet fire extinguisher is a common fire-fighting equipment suitable for various places, such as residences, public places, offices, etc. The fire extinguisher is mainly composed of a water pump, a pressure tank, a nozzle, a valve and other components. Its working principle is to spray water and a special foam mixture onto the fire source to form a covering layer, making it difficult for the fire source to contact oxygen and eventually be extinguished. 2. Working principle of wet fire extinguisher The working principle of wet fire exting
How wet fire extinguishers work
Wet fire extinguisher is a common fire extinguishing equipment. Its working principle is as follows: Water supply: Wet fire extinguishers mainly rely on water supply for fire extinguishing. Generally speaking, wet fire extinguishers are connected to the building's automatic water supply system to ensure an adequate and continuous supply of water. Pressure control: There is a pressure control system inside the wet fire extinguisher to maintain the pressure of water inside the fire extinguisher. Typically, this control system includes a pressure switch and a pressure regulator to e
There are three commonly used water-based fire extinguishers:
1. Water fire extinguisher. It refers to a fire extinguisher whose cylinder is filled with clean water and uses carbon dioxide or nitrogen as the driving gas. There are generally two specifications: 6L and 9L. The fire extinguisher containers contain 6L and 9L of water respectively. 2. Water-based foam fire extinguisher. Aqueous film-forming foam fire extinguishing agents (AFFF) are generally used and fire extinguishers use nitrogen as the driving gas. Aqueous film-forming foam fire extinguishing agent can quickly form a layer of water film on the surface of hydrocarbon substances that
How to use portable water-based fire extinguisher
When using a portable fire extinguisher, it is best to operate it alone. You should hold the handle of the portable fire extinguisher and rush to the fire quickly. Put down the fire extinguisher about 5 meters away from the fire point (when using it outdoors, it should be in the windward direction), and unplug the fuse. Pin (do not point the head of the fire extinguisher towards the human body to prevent it from ejecting and injuring people), hold the front end of the spray belt with one hand, and press the handle firmly with the other hand, and the fire extinguishing agent will spray out from
Introduction to water-based fire extinguishers and how to use them
1. Water-based fire extinguishers emerged in the 1980s and have a physical fire extinguishing mechanism. The agent can form and expand a thin water film on the surface of combustible materials to isolate the combustible materials from the air and achieve fire extinguishing. Through the atomizing nozzle, fine water mist is sprayed out, which spreads over the fire field and evaporates heat, quickly reducing the temperature of the fire field, and at the same time reducing the concentration of oxygen in the air in the combustion zone to prevent re-ignition. Good re-ignition resistance is an unpara
Dry powder fire extinguisher fire extinguishing principle
Dry powder fire extinguishing agent is a dry and easy-flowing fine powder used for fire extinguishing. It is composed of inorganic salts with fire extinguishing effects and a small amount of additives that are dried, crushed, and mixed to form a fine solid powder. It is a fire extinguishing agent widely used in firefighting and is mainly used in fire extinguishers. In addition to special dry powder chemical fire extinguishing agents for extinguishing metal fires, dry powder fire extinguishing agents are generally divided into two categories: BC dry powder fire extinguishing agents and A
How to use a portable dry powder fire extinguisher
When using a dry powder fire extinguisher to extinguish flammable or flammable liquid fires, you should aim at the main part of the flame and spray. If the liquid fire being extinguished is flowing and burning, you should aim at the root of the flame from near to far, and spray from left to right until all the flames are extinguished. If a flammable liquid is burning in the container, users should aim at the root of the blaze and rock it to mow, so that the sprayed dry powder flow covers the entire container opening. When the blaze is driven out of the container, the user should continue to sp
How to use a portable foam fire extinguisher
You can carry the lifting ring on the upper part of the cylinder and rush to the fire scene quickly. At this time, care should be taken not to tilt the fire extinguisher excessively, nor to hold it horizontally or upside down, to prevent the two agents from mixing and spraying out in advance. When you are about 10 meters away from the ignition point, you can turn the cylinder upside down, hold the lifting ring tightly with one hand, hold the bottom ring of the cylinder with the other hand, and aim the jet at the burning object. When extinguishing a flammable liquid fire, if it is burning in a
