�  Class C Materials: This refers to electrical materials and equipment that can cause fires quickly and
                    present a serious risk of arc flash due to electrical faults.
                 �  Class D Materials: Materials in this class are volatile and can ignite rapidly. Examples include metals like
                    magnesium, potassium, and sodium, which are highly reactive and combustible.
                 �  Class K Materials: This refers to cooking oils and fats typically found in commercial kitchens or places where
                    large-scale cooking operations occur. These materials are characterised by their high heat content and
                    ability to ignite easily, often leading to fires that can be challenging to extinguish with traditional methods.
                 Understanding these classifications helps in assessing fire risks, implementing appropriate safety measures,
                 and responding effectively to prevent or mitigate fires based on the properties and behaviors of different
                 materials.

                 Examples of ignition sources categorised by their nature:
                 �  Open Flames: Examples include gas ovens, lighters in smoking areas, and welding torches.
                 �  Sparks: Generated from activities like wood or metal sawing, grinding, or other types of equipment that
                    produce friction.
                 �  Heat Sources: These encompass combustion engines, space heaters, ovens, and machinery that generate
                    heat during operation.
                 �  Chemical Ignition: Certain chemicals can combust under normal working temperatures, contributing to
                    fire risks.
                 Here's a table summarising the classes of fire and the suitable fire extinguishers for each class:

                 Using  a  fire  extinguisher  effectively  involves
                 following a straightforward method known as the
                 PASS technique. Here are the steps:                         Discharge
                 Step 1:  Pull the pin or safety clip located at the          Nozzle
                         top  of  the  fire  extinguisher.  This  step
                         prepares the extinguisher for use.
