Risk Analysis and Control Measures in Pipe Welding Activities on Construction Sites

Pipe welding is a critical activity in construction projects that presents significant safety challenges, with its core tasks initially assessed at a high-risk level (risk score: 12). The overall process involves numerous hazardous supporting activities, notably lifting operations using Heavy Equipment (HE), which also carry a high-risk potential for severe injuries, equipment damage, and fatalities. This study identifies various hazards across these integrated tasks—from welding arc light and fumes to unstable ground conditions and improper manual handling—and evaluates control measures to mitigate these risks to a moderate (score: 6) or low (score: 3) level. Key risk mitigation strategies include ensuring welder and operator competency, conducting daily inspections of welding and lifting gear, utilizing appropriate Personal Protective Equipment (PPE), enforcing clear communication protocols, and maintaining direct supervision by safety personnel. The findings demonstrate that a comprehensive risk management approach, combining technical, administrative, and behavioral controls for all related activities from lifting to welding, is essential for significantly reducing workrelated accidents and creating a safer construction environment.
