Before Samantha welds inside a grain silo, her employer must issue ____.

Before Samantha welds inside a grain silo, her employer must issue ____.

• A. Hot Work Permit
• B. Work Permit
• C. Confined Space Permit
• D. Welding Permit

Answer: (A)

Welding creates heat, sparks, and the potential to ignite flammable materials, so the activity is treated as hot work. A hot work permit is the formal authorization that ensures all fire-prevention controls are in place before the job starts—like removing or shielding flammable materials, isolating energy sources, having a fire watch, and ensuring proper ventilation and atmospheric checks. In a grain silo, the danger is even greater because grain dust can ignite and the space is a confined area with limited ventilation, so the permit helps ensure those safeguards are in place. While a confined space permit would also be required to enter and work inside a silo, the specific document that authorizes the welding task itself is the hot work permit.
