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

• heat
• oxygen
• combustible substance

The fire is extinguished if one of the three causes of the fire is removed. If the combustible material is removed, further spread of the fire through the material is prevented. If we prevent access of oxygen to a combustible substance, we destroy the relationship between the substance and the oxygen that only this needs for burning. If we extinguish by cooling, we lower the temperature below the ignition point of the burning substance

Fire

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

A fire

A fire is an uncontrolled spread of fire in a room or in nature. It often causes material damage and threatens human and animal lives.

Extinguishing

We put out the fire by preventing the access of air and lowering its temperature or by removing its combustible parts.

Carbon monoxide - CO

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

Type S aerosol

Type S aerosol does not have a bad effect on precision instruments, electrical components and other equipment. Aerosol extinguishing agent type S and its suspension of inert gas upon activation fill the volume of the room in which the fire occurred. The size of the chemical particles is up to one micron and they fill the space practically everywhere.

Type S aerosol is very effective in extinguishing fires, so it is often used mainly in the following areas:
- Wind farms, i.e. wind turbine cabin, rotor, control system and tower are places where fire can occur
- Vehicles, buses, cars, trucks, boats, planes, cargo
- Electrical cabinets, inverters, servers and server cabinets
- Power supply and power supply facilities, including thermal power plants, solar power plants, wind power plants, nuclear power plants, power supply companies.
- Underground extensive galleries, including subway, electrical gallery, tunnels, communication pipelines.
- Facilities transformer stations.
- Petrochemical facilities, including storage space for flammable liquids.
- CNC and other high value machines.

Strontium nitrate

Molecular formula: Sr(NO3)2

Usage:
It is used to make red products for fireworks, signal flares, burner inner lining, analytical reagent, optical glass, LCD glass substrate and fire extinguishing reagents such as aerosol, cathode material of tubes in the electronic industry, automotive airbags and high-quality paints In medicine.

Potassium nitrate

Potassium nitrate (KNO3) is a salt of nitric (V) acid (HNO3). It is known under the name common saltpeter, but the name English salt was also used. It is used as an oxidizer (black powder), an artificial fertilizer (provides plants with the necessary nitrogen), a food additive E252, and also in the manufacture of pyrotechnics and military explosives.

ABC Powder

ABC powder or Monoammonium Phosphate is a multi-purpose chemical powder for extinguishing type A, B and C fires.

- Use of fire extinguishing powder type A:
The dust will extinguish a fire where the temperature reaches 200⁰C. We can extinguish hard flammable new substances such as wood, paper and plastic.

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

- Use of ABC powder to extinguish fire on electrical installations:
It is also safe and effective when extinguishing fires on electrical installations, because the dust is non-conductive. Fires that are likely to contain electrical voltage must be extinguished with a suitable substance, such as powder, so that the electrical voltage is not transferred to the person extinguishing the fire.
