The basis of burning is the burning triangle, which combines the following elements:

• Heat
• Oxygen
• flammable material

A fire is extinguished when one of the three causes of fire is eliminated. Removing the combustible material prevents further fire spread through the material. When we prevent oxygen from reaching a combustible substance, we destroy the bond between the substance and oxygen, which only the substance needs for combustion. When extinguishing by cooling, we lower the temperature below the ignition temperature of the burning substance.

Fire

What is fire, anyway? Fire is the rapid oxidation of materials in the chemical combustion process, releasing heat, light, and various products of chemical reactions. This is the chemical explanation of fire. The flame, which we see during burning, is the visible part of the fire and consists of glowing hot gases.

fire

A fire is the uncontrolled spread of flame in a room or in nature. It often causes material damage and endangers the lives of people and animals.

Delete

We extinguish the fire by preventing air from entering, lowering its temperature, or removing its flammable parts.

Carbon monoxide - COmonoxide - CO

Carbon monoxide (the old term is carbon monoxide) is a deadly gas produced when there is not enough oxygen during combustion. It is colorless, odorless, and tasteless, so we don't notice it. Signs of poisoning include nausea, dizziness, fatigue, and more. In Slovenia, an average of 50 people die each year from poisoning with this gas.

Aerosol Type S

Type S aerosol has no adverse effects on precision instruments, electrical components, and other equipment. Upon activation, the Type S aerosol extinguishing agent and its inert gas suspension fill the volume of the room in which the fire broke out. The chemical particles are up to one micrometer in size and fill virtually the entire space.

Strontium nitrate

Molecular formula: Sr(NO3)2

Use:
It is used to manufacture red products for fireworks, signal flares, burner linings, analytical reagents, optical glass, LCD glass substrates and fire extinguishing reagents such as aerosols, cathode tube material in the electronics industry, automobile airbags and high-quality paints in medicine.

potassium nitrate

Potassium nitrate (KNO3) is a salt of nitric acid (HNO3). It is known as common saltpeter, but was also commonly called Epsom salt. It is used as an oxidizing agent (black powder), as an artificial fertilizer (provides plants with the necessary nitrogen), as a food additive (E252), and in the production of pyrotechnics and military explosives.

ABC powder

- Use of fire extinguishing powder Type A:
The dust extinguishes a fire when the temperature reaches 200 °C. We can extinguish new, highly flammable materials such as wood, paper, and plastic.

- Use of fire extinguishing powder Type B and C:
The powder interrupts the chain reaction of flammable liquids and gases. These include combustible substances such as gasoline, oils, propane, and natural gas.

- Use of ABC powder to extinguish fires at electrical systems:
It is also safe and effective for extinguishing fires in electrical systems because the dust is non-conductive. Fires where there is a possibility of electrical current must be extinguished with a suitable agent, such as powder, to prevent the electrical voltage from being transferred to the person extinguishing the fire.
