Which condition indicates immediate use of the SCSR?

• A. Sight of smoke
• B. Having a daily check of equipment
• C. After lunch break
• D. When the shift ends

Answer: (A)

Seeing smoke underground is a clear sign of hazardous air and potential fire risk. The moment smoke is observed, you should immediately don the Self-Contained Self-Rescuer so you have a safe air supply while you move to safety or assist others. Routine checks of equipment are preventive maintenance and don’t signal an emergency, so they don’t require using the SCSR right away. Times like after lunch or at shift end aren’t indicators of an emergency atmosphere. Always follow your training and the mine’s emergency procedures for using the SCSR when the air quality becomes unsafe.
