What are the safety risks of overheating PVC during welding for sculptures?

Overheating PVC during welding for sculptures poses several safety risks that artists and fabricators should be aware of. First, excessive heat can release toxic fumes, including hydrogen chloride gas, which is harmful when inhaled and can cause respiratory irritation or long-term health issues. Proper ventilation or respiratory protection is essential to mitigate this risk.

Second, overheating can weaken the structural integrity of the PVC, leading to brittle or deformed sculptures. This compromises the durability and aesthetics of the artwork. Additionally, melted PVC can cause severe burns if it comes into contact with skin, so protective gloves and clothing are recommended.

To minimize these risks, use controlled heat settings, work in well-ventilated areas, and wear appropriate safety gear. Understanding these hazards ensures safer and more successful PVC welding projects for sculptures.
