What statement about fire extinguisher criteria is accurate?

• A. Right type for each class of fire
• B. Kept outdoors in all climates
• C. Never inspect extinguishers
• D. Not required to be maintained

Answer: (A)

The main concept is that extinguishers must be the right type for the class of fire. Different fires respond to different extinguishing agents, so using the correct type is essential for effective suppression and to avoid creating new hazards. In a mining or surface-mine setting you may encounter fires from ordinary combustibles, flammable liquids, or energized electrical equipment, so selecting extinguishers labeled for those specific classes ensures the agent acts on the fuel involved without causing harm. Using the wrong type can be ineffective or dangerous—for example, water can worsen electrical fires or powder can spread a fire unnecessarily in some scenarios. The other statements aren’t accurate in practice. Fire extinguishers aren’t kept outdoors in all climates; they should be accessible and protected from damage, and they require regular inspection and maintenance to ensure they work when needed. They are not never inspected and they do require ongoing maintenance and servicing.
