How would you justify the selection of a particular extinguisher for a specific area in a factory?

• A. Based on fire type hazard (A, B, C), fuel, electrical risk, occupant safety, accessibility, and potential collateral damage.
• B. Based on the color of the extinguisher.
• C. Based on cost alone.
• D. Based on the building occupant's preference.

Answer: (A)

The main idea is to choose an extinguisher based on the fire hazard present in the area and the conditions around it. In a factory, fires can involve ordinary combustibles, flammable liquids, or energized electrical equipment, so you assess the likely fire class and select an extinguishing agent that is effective for that class while also considering the environment. For electrical risks, non-conductive or low-toxicity options and those that won’t cause additional damage to electrical systems are preferred, and you must balance how the agent might affect occupants and nearby equipment. Accessibility, visibility, and ease of use matter too, ensuring people can reach and operate the extinguisher quickly in an emergency without creating additional risks. You also consider potential collateral damage, such as residues or fumes that could harm sensitive machinery or pose downstream hazards. Color, cost alone, or occupant preference do not determine suitability; the choice should be driven by the fire hazard and safety factors to provide effective and safe fire protection.
