Question: Which of the following scenarios absolutely requires a hot work permit before starting any welding or cutting operations?
Answer options:
- Welding in a designated welding booth with no combustibles nearby
- Using a portable cutting torch outdoors on a clear day, away from structures ✅ Performing repair welding on a piece of equipment in an area previously used for storing flammables
- Grinding a small weld bead off a new structural beam in an open-air fabrication yard
Correct answer: Performing repair welding on a piece of equipment in an area previously used for storing flammables
Explanation: A hot work permit is essential when welding or cutting in areas where a fire hazard exists, particularly near combustible materials or where flammable vapours may be present, even if no longer stored there. Designated welding booths often do not require permits as they are designed for safe hot work. Outdoor activities away from structures or grinding on new beams in open yards typically pose lower risks, but specific site rules always apply.
