What examination shall be made before taking a machine inby the last open crosscut of a working section?

• A. Methane gas examination inby the last open crosscut
• B. A visual inspection only
• C. A noise level check
• D. A general safety inspection without gas testing

Answer: (D)

Before moving a machine inby the last open crosscut, you must perform a methane gas examination in that area. This checks the atmosphere for flammable gas so you’re not introducing ignition sources into a hazardous environment. Methane can accumulate or be drawn into the working section even if everything else seems fine, so relying on a visual inspection or a general safety check alone isn’t enough. A gas test specifically confirms whether conditions are safe for operations; if methane is above the allowable limit, you’d need to improve ventilation or delay moving the machine. The other checks—visual inspection, a noise check, or a broad safety review without gas testing—don’t address the key hazard of flammable gas and thus aren’t sufficient in this situation.
