CANADA's Transportation Safety Board (TSB) has recently issued its statistics for 2005. Five pipeline 'accidents' were reported in the year, down from seven in 2004, and less than the five-year average of 16. Pipeline activity is estimated to have decreased by 1% over the year, and the accident rate has decreased to 0.4 pipeline accidents per exajoule (a measure of the volume of oil or gas flowing through a pipeline); the equivalent figure in 2004 was 0.5, and the 2000-2004 average is 1.48. The last fatal pipeline accident in the portion of the industry under federal jurisdiction occurred in 1988, and the last accident involving serious injury occurred in 2000. The TSB reports that, in 2005, 79 pipeline 'incidents' were reported in accordance with its mandatory reporting requirements, an increase of five from the 74 in 2004, and an increase from the five-year average of 44. Over 90% of those incidents involved uncontained or uncontrolled release of small quantities of gas, oil, and high vapour-pressure products such as propane, butane, or natural gas liquids.
