What are the precautions for chimney repair?

Unqualified motors must be immediately discontinued and repaired. Test results should be recorded and preserved. During repairs, be mindful of wind direction to avoid being downwind of workers, to prevent poisoning or burns. Operators must not perform repairs barefoot or in shorts. Pants legs and sleeve cuffs should be tightly secured, and gloves must be worn. Individuals with hypertension or allergies are strictly prohibited from participating in the operation. If nausea or dizziness occurs during the repair process, operations must be immediately halted.

Drinking is strictly prohibited before work. Staff must remain focused. Safety belts and helmets must be worn. Completion is only achieved after passing inspection, as this is ultra-high-altitude work, and fatigue climbing is forbidden. During breaks, the safety belt must be fastened, and rest periods should not be prolonged. After reaching the top, extended rest is allowed. Always wear protective gear like helmets before commencing work.
