What precautions must be taken when miners work in areas or places where fire or explosion hazards exist?

• A. No smoking or open flames
• B. Wear safety goggles only
• C. Use ear protection
• D. Increase ventilation

Answer: (A)

In areas with fire or explosion hazards, the most crucial precaution is eliminating ignition sources. Prohibiting smoking and open flames directly removes the main cause of ignition, reducing the risk of a spark or flame lighting flammable gases or dust. Wearing safety goggles protects the eyes from debris but doesn’t address ignition risk. Ear protection relates to hearing and is not a fire-explosion precaution. Increasing ventilation can help dilute flammable atmospheres, but it doesn’t eliminate ignition sources and isn’t a standalone guarantee against explosions.
