Fire Extinguishing Simulation by Anafarma Students

Monday, November 12th, eighty one students of Anafarma held joint practice with Malang fire fighters squad. This was carried out in a series of learning courses of Occupational Health and Safety (OHS) & Health Promotion. Noting that, Polkesma has implemented a competency-based curriculum by which 60% practice and 40% theoretical learning. The practical learning commonly done in the laboratory and could be conducted in the field by the Anafarma D-III freshman.

This time, students practiced to use various types of personal protective equipment (PPE) and Fire Extinguishers led by M. Teguh Budi W, SH. Based on his explanation, fire can be formed into three elements; heat, air and fuel which can cause or emit heat and light. These elements are known as fire triangles. Although with the presence of these elements, fire has not occurred yet, it was only producing incandescent. Meanwhile, burning fire occurs when there is a fourth component, namely the chain of chemical reactions. This theory is known as the Fire Pyramid or Tetrahedron.

Fire occurs if there is at least 15% of the volume of oxygen in the air. The air in the atmosphere contains 21% of oxygen. A heat is needed to reach the ignition temperature so that it can trigger a fire. Heat sources include solar heat, hot surfaces, friction, exothermic chemical reactions, electrical energy, electric sparks, welding flames etc. While fuel is all objects that can trigger combustion such as wood, plastic, sugar, fat, paper, gasoline, alcohol, acetylene, propane, carbon monoxide, butane etc.

Fire classification is based decree issued by Minister of Manpower of Indonesia through PERMEN Regulation: No/Per/04/Men/1980 are as follows:

1. Class A: fire caused by solid fuels such as wood, cloth, paper, rubber etc.

2. Class B: fire caused by liquid fuels such as gasoline, methane, diesel fuel etc.

3. Class C: fire caused by failure of electrical equipment.

4. Class D: fire caused by metals such as magnesium, aluminum etc.

The practice was continued to the field led by with the Malang City Fire Team. It was started with an explanation of how to extinguish fire with Extinguishers. The wind direction is the crucial thing that must be considered to extinguish the fire.  To extinguish the fire, we should take position opposite direction of the wind.  The type of extinguishing media or commonly called APAR is generally divided into 3 types:

  1. Liquid   : water, foam
  2. Solid : Dry Chemical or ABC Powder containing Sodium Bicarbonate, Potassium Bicarbonate, Potassium Bicarbonate, Potassium Chloride etc.
  3. Gas   : CO2, N2 and Hallon (however, the use of hallon is prohibited because it is harmful to the ozone layer)

The students given a chance to extinguish the fire using solid media (Dry Chemical) and Liquid (water). To extinguish the fire extinguishing media must be installed on fire-fire so that the fire quickly extinguishes. If the extinguishing media will only process the outage process for longer. To put out fire, the extinguisher was aimed at the base of fire to make it effectively.

Riska, lecturer of Anafarma stated that the joint practice is expected to make students understand and be able to handle fire in the surrounding environment.
