Fires can happen at any moment, and it’s important to be prepared. Fire extinguishers are a crucial tool for controlling small fires, and it’s essential to choose the right type for the job. With so many options available, it’s easy to get overwhelmed. In this article, we’ll take a closer look at the different types of fire extinguisher service in Sydney and when they should be used.
Before diving into the various types, it’s essential to understand the classes of fires. Fires are classified into five categories:
Class A fires involve ordinary combustibles like wood, paper, and cloth.
Class B fires involve flammable liquids and gases like gasoline, oil, and propane.
Class C fires involve electrical equipment like computers, appliances, and wiring.
Class D fires involve flammable metals like magnesium, titanium, and potassium.
Class K fires involve cooking oils and fats in commercial kitchens.
Water Fire Extinguisher (Class A)
Water fire extinguishers are designed to extinguish Class A fires. They work by cooling down the fire and removing heat from it. However, water fire extinguishers should never be used on Class B or Class C fires, as they can spread the flammable liquid or create a dangerous electrical shock.
Foam Fire Extinguisher (Class A and Class B)
Foam fire extinguishers work by smothering the fire and removing oxygen. They are effective on Class A and Class B fires and are commonly used in homes and businesses.
Dry Chemical Fire Extinguisher (Class B and Class C)
Dry chemical fire extinguishers work by creating a barrier between the fire and oxygen, cutting off the fire’s supply of oxygen. They are effective on Class B and Class C fires and are commonly found in offices, schools, and other public buildings.
Carbon Dioxide (CO2) Fire Extinguisher (Class B and Class C)
CO2 fire extinguishers work by removing oxygen from the fire, effectively smothering it. They are effective on Class B and Class C fires and are commonly used in computer server rooms and other areas with sensitive electronics.
Wet Chemical Fire Extinguisher (Class K)
Wet chemical fire extinguishers are specifically designed for use on Class K fires, which involve cooking oils and fats in commercial kitchens. They work by creating a barrier between the fire and oxygen, cutting off the fire’s supply of oxygen.
