Fire Mock Drill on June 14 2019

The Security Department organized a Fire Mock Drill on June 14 2019 at the University Pavilion. The objective of the demonstration was to sensitize staff on Disaster preparedness and emergency response skills. Members were also sensitized on classes of fire and firefighting appliances.

Some of the causes of fire are negligence, overloading power sockets, poor housing keeping and simultaneous heating.

Classes of fire

Fire class is a term used to denote the type of fire, in relation to the combustion materials which have ignited. This has onward impacts on the type of suppression or extinguishing materials which can be used. Class letters are often assigned to the different types of fire

Class A

Class A fires are defined as ordinary combustibles. These types are fires use commonly flammable material as their fuel source. Wood, fabric, paper, trash, and plastics are common sources of Class A fires. Class A fires are commonly put out with water or monoammonium phosphate because of its ability to smother fires in these types of materials.

Class B

The Class B fire is defined as one that uses a flammable liquid or gas as its fuel base. Common liquid based fuel sources include petroleum based oils and paints, kerosene, and gasoline. Flammable gases such as butane or propane are also common fuel sources in Class B fires. Smothering these types of fires to remove oxygen is a common solution as are chemical reactions that produce similar effects. 

Class C

The Class C fire is defined as a fire that uses electrical components and/or energized equipment as its fuel source. To extinguish such fires you cut the power off and use non-conductive chemicals to extinguish the fire.       

Class D

The Class D fire is defined as one that uses a combustible metal as its fuel source. Examples of such combustible metals include titanium, magnesium, aluminum, and potassium. Note that there are also other metals with combustive properties you may encounter. Class D fires are a danger in laboratory environments. To extinguish a Class D fire, use a dry powder agent. This absorbs the heat the fire requires to burn and smothers it as well.
