Delta P, or differential pressure, is a critical phenomenon that can pose fatal risks to divers working around underwater structures, pipes, and valves. This pressure difference can create powerful forces capable of trapping and entrapping divers, making it a serious hazard for underwater welders. Understanding and mitigating the dangers of Delta P is essential for … Read more
Smoking cigarettes and being an underwater welder can be a dangerous combination due to the increased risk of lung diseases and systemic inflammation associated with welding fumes (WFs) and smoking. WFs can cause pneumonia, lung function abnormalities, and a significant decline in FEV 1 and FVC, especially in smokers. A meta-analysis found that the pooled … Read more
