2005/02/ NPEC - Open Discussion "Pressure Equipment Safety"4 A Brief Look at The Importance of Pressure Equipment to Alberta

2005/02/ NPEC - Open Discussion "Pressure Equipment Safety"5 Natural Resources linking to Pressure Equipment Alberta, the oil and gas producing province of Canada in % (oil) & 80% (gas) Over 1/3 of Canadian petrochemical plants and refineries Over 90% of Canadian gas processing facilities Highest per capita of pressure equipment usage in North America

2005/02/ NPEC - Open Discussion "Pressure Equipment Safety"6 There is a “Cost” “Unfortunately, there is a long history of pressure equipment safety problems. The first technical paper published by England’s Institute of Mechanical Engineers addressed this problem in 1848, and was entitled ‘Boiler Explosion at Dudley’ “Improperly operated or maintained, pressure vessels can fail catastrophically, kill and injure workers and others, and cause extensive damage even if the contents are benign”

2005/02/ NPEC - Open Discussion "Pressure Equipment Safety"7 Yes, it did happen in Alberta
