| Abstract |
Many petroleum and methane tankers are equipped with installations for producing inert gases (nitrogen, carbon dioxide, etc.) which are pumped into the tanks to replace the air and prevent the formation of explosive atmospheres. Use of these inert gases involves an asphyxiation hazard due to lack of oxygen. These directives prescribe safety rules for workers engaged in repair work on tankers: inspection of vessel on arrival at shipyard; issuing of degassing certificate (indicating oxygen level); shutting of valves and other access to inert gas tanks; monitoring of oxygen level; permits-to-work, etc. |
