LIGHT FIRE EXTINGUISHER (APAR)

The meaning of APAR is an abbreviation of Light Fire Extinguisher. APAR is a term used for portable fire extinguishers that can be carried or can be moved easily. In contrast to hydrants that are embedded in an area, the use of APAR is more practical, because it is easy to use and can be brought to the source of the fire.

Based on the type of fire extinguisher can be divided based on the composition of the ingredients in it. For example, APAR water, APAR Foam, APAR Dry Chemical, APAR CO2, and others. Each fire extinguisher has different characteristics depending on the nature of the composition of the material in extinguishing the fire. For example, dry chemical fire extinguishers are fire extinguishers that contain a mixture shaped like dry chemical flour. Dry Chemical APAR (DC type APAR) is specifically used to extinguish fires that originate from short circuits, oil spills, or chemical substances that easily react with water.

The use of the type of fire extinguisher must be correct, because if it is not appropriate, it will not be effective in extinguishing the fire and allow new potential hazards. For example, when a fire occurs from an oil spill, DO NOT use a water type fire extinguisher, because it will expand the fire area. We know that water and oil don't mix, so if you use water, the oil will form a separate layer above the water, so the oil will still burn, while the water underneath will spread the burning oil in all directions. This causes the fire to spread. Therefore, it is necessary to have an understanding of APAR.

Before discussing the APAR in more detail. It must first be understood the theory of fire that is used to find out what ways the fire can be extinguished. The following is an explanation of API Theory.

A. API THEORY

The theory of fire discusses the basic composition of the creation of fire, namely oxygen, heat, and fuel. The three compositions are referred to as the fire triangle.

If any of the fire-forming compositions are removed, the fire can be extinguished. For example, if the fuel is taken, then the fire can be extinguished. If oxygen is blocked, the fire is also extinguished. Now! This principle is used in fire extinguishers and gives rise to many variants of fire extinguishers depending on the source of ignition.

Based on the source, fire is divided into several classes, namely Class A, Class B, Class C, and Class D, and there are even up to Class E. Depending on several versions, namely the version according to NFPA and SAA. NFPA or National Fire Protection Association and SAA or Standard Australian Association

is an agency that handles fires. Yes, like the Fire Department (DPK) in Indonesia. The different classifications of fires according to their version are shown in the following figure:
