For methane checks during auger operation, when should they be performed?

• A. Before welding and at the start of shift
• B. Only at the start of shift
• C. Only before welding
• D. Only after welding

Answer: (A)

Gas checks for methane in auger work are done to prevent ignition and to ensure a safe working atmosphere. Checking before any welding ensures that there is no flammable gas present where sparks or heat from welding could ignite it. Checking at the start of the shift establishes a safe baseline for the entire shift, since gas levels can change with ventilation, ongoing operations, or new leaks. If you only check at one time, you create a safety gap: checking only before welding could miss methane that accumulates later, and checking only at the start of shift could miss an increase in gas levels during the shift or after welding has begun. Checking after welding would be too late to prevent ignition risks during the welding process. So, performing methane checks both before welding and at the start of the shift provides the necessary protections for hot work and for ongoing auger operation.
