Summary
This investigation examines ammonia exposure during filling-valve replacement at Naturkraft’s Kårstø power station. Tank overpressure drove solution through the opened flange, injuring two workers. It identifies inadequate risk assessment and chemical education, emergency-shower water failure and shortcomings in emergency exercises, while examining protective equipment and the response.
