Fire Extinguishers

Fire extinguisher types: what are they, and what are their details?

• Foam Fire Extinguishers:

The finest types of fire extinguishers are filled with organic materials and chemical components, resulting in foam used to extinguish fires caused by the combustion of liquid materials such as oil, petroleum, and alcohol. They insulate the fire from oxygen and cool it with water; they cannot be used with fires caused by electricity. Foam fire extinguishers come in two types:

• Chemical Foam Fire Extinguishers:

The foam is produced by a chemical reaction of various chemicals such as fluoroprotein, petrosal, and cosil. They are supplemented with materials that help them withstand shocks.

• Mechanical Foam Fire Extinguishers:

The foam is produced by mixing foam liquid with water and air, with the foam being pressurized by carbon dioxide gas.

Properties of foam fire extinguishers:

• Adhesion property to vertical and horizontal surfaces.
• Heat resistance to prevent the bubbles from bursting due to heat.
• Bubble cohesion strength to prevent them from breaking from air or water.
• Sliding property over the surface of the ignited liquid and preventing air from reaching it.

• Powder fire extinguishers:

Multi-purpose fire extinguishers are used to extinguish fires caused by wood, paper, and textiles, as well as fires caused by flammable liquids and gases. This type of extinguisher produces a powder that can cause visibility impairment, so caution must be exercised when using it. It comes in various types and forms, including:

• Wet chemical fire extinguisher:

Fire extinguishers filled with liquid chemical organic substances used effectively to extinguish cooking oil fires.

• Dry powder fire extinguishers:

Fire extinguishers filled with dry chemical powder, such as sodium bicarbonate or calcium carbonate. The cylinder is pressurized with nitrogen gas. They are used to extinguish all types of fires by isolating the fire from the surrounding oxygen. This includes fires caused by burning petroleum and flammable metals like sodium, potassium, and magnesium.

• CO2 fire extinguisher:

CO2 fire extinguishers are filled with carbon dioxide gas, which transforms into a liquid under high pressure. It works by isolating the burning area from oxygen and helping to reduce the temperature. The cooling value is estimated to be around “60-110” heat units. It is characterized by its rapid spread and its non-conductivity to electricity. A CO2 fire extinguisher is used to extinguish fires caused by igniting liquid petroleum substances or electrical fires. However, they are not suitable for fires involving sensitive electronic devices. It is important to use this type of extinguisher in areas far from air currents to prevent the poisoning or suffocation of individuals, as it can cause a loss of visibility.

• Halon fire extinguisher:

The halon fire extinguisher is a type of handheld fire extinguisher used to quickly extinguish and suppress all types of fires. However, its frequent use is not recommended, especially in enclosed spaces, because the vapor it produces contains chlorine, fluorine, and bromine compounds that are harmful to the ozone layer. However, it does not cause harm if not inhaled in large quantities. How to use a Halon fire extinguisher?

• The halon fire extinguisher should be directed towards the nearest end of the fire in the case of fires involving flammable liquids.
• The halon fire extinguisher should be aimed downward at the base of the fire and moved upward if the burning liquid is cascading from above.
• The halon fire extinguisher should be aimed directly at the fire in a straight line if the fire is caused by an electrical contact.

• Water fire extinguisher:

A water fire extinguisher is a pressurized fire extinguisher filled with ordinary water. It is used to extinguish ordinary fires but cannot be used for fires caused by electrical contact. In the case of electrical fires, water will not extinguish the fire but rather increase its spread.

To relieve you of the burden of purchasing a new fireball extinguisher at a high price, we offer you a fire extinguisher refilling service. We refill the fireball extinguisher for immediate and repeated use. We also ensure that the extinguishers are filled with suitable substances such as water, foam, carbon dioxide, and others. We check the gas pressure inside them to ensure their effectiveness against the risk of fire.

How does Rayde’s team help you with fire extinguisher refilling?

• We check the pressure gauge quality of the fire extinguisher.
• We inspect the external structure to ensure its safety and the absence of corrosion.
• We inspect the hose and discharge horn to ensure there are no cracks.
• We check the valve openings for safety and ensure they are free from obstructions.
• We replaced the locking pin and cleaned the fire extinguisher.

Fire Extinguisher Refilling Prices:

Refilling fire extinguishers is generally more cost-effective than purchasing a new one. The fire cylinder refilling price varies based on the following factors:

• Different types and specifications of the extinguisher.
• Variation in the quality of refilling materials.
• Different sizes of fire extinguishers.
• The extent of gas consumption by the extinguisher.

Fire Extinguisher Maintenance:

To ensure the efficiency of the fire extinguishing system when needed, we offer a fire extinguisher maintenance service for all types and shapes of extinguishers regularly and in accordance with civil defense regulations and laws. Our safety team examines and inspects the extinguishers using specialized inspection devices to ensure the functionality of all parts of the extinguishers, either on a monthly or annual basis.

How does Rayde’s team help you with fire extinguisher maintenance?

• Quick manual inspection to check the gas pressure inside.
• Regular follow-up and internal inspection of all parts of the extinguisher.
• Providing all necessary genuine spare parts for fire extinguisher renewal.
• Issuing civil defense certificates and licenses.

Fire Extinguisher Maintenance Prices:

You can obtain suitable prices for fire extinguisher maintenance from Rayde. We offer you special contracts at low prices to ensure your safety from accidents and fires. The prices vary based on the following factors:

• Different types and specifications of the extinguisher.
• Variation in the quality of refilling materials.
• Different sizes of fire extinguishers.
• Duration of the agreed contract with the company.

Fire Extinguisher Renewal:

We offer you a service for renewing fire extinguishers in public places and government facilities to control fires and greatly reduce the chances of their occurrence, which can be devastating and harmful to humans. It also provides people with a sense of security and reduces fear in crowded areas, leading to the safe preservation of the environment.

When do you need fire extinguisher renewal service?

• If the fire extinguisher has not been used for a long period of time.
• If the pressure gauge in the extinguisher is dropping.
• In case any part of the fire extinguisher is damaged.
• If the inspection label and maintenance date are missing.

The fire extinguisher renewal service helps you minimize the cost of purchasing a new extinguisher.

Fire Extinguisher Components:

• Cylinder:

It is the body of the fire extinguisher that contains the compressed chemical firefighting agent. It contains concentrated sulfuric acid and sodium bicarbonate solutions, which generate a strong jet of water, carbon dioxide gas, or compressed air when mixed.

• Nozzle:

A metal piece installed at the end of the hose to control the water flow. It facilitates directing the firefighting agent towards the flames smoothly and without any obstructions using the operating lever.

• Handle:

The handle of the fire extinguisher assists in carrying and transporting it from one place to another with ease.

• Safety Pin:

A pin placed on the operating lever to prevent tampering or accidental discharge of the firefighting agent.

• Pressure Gauge:

An indicator that shows the presence of sufficient pressure inside the fire extinguisher to activate it.

Fire Extinguisher Installation:

We specialize in installing fire extinguishers in both public and private spaces to ensure easy access in the event of a fire. We adhere to international standards and tailor the installation process to meet your specific needs and primary objectives.

How do you extinguish electrical fires?

1. Do not use water-based fire extinguishers if the electrical power is still connected, as it can increase the risk of electrical shock.
2. Use an appropriate electrical fire extinguisher, such as a Halon fire extinguisher, a CO2 fire extinguisher, dry powder fire extinguishers, or foam fire extinguishers.
