HU­MAN ER­ROR GROW­ING FAC­TOR, DATA SHOWS

Saskatoon StarPhoenix - - CANADA -

Hu­man er­ror — whether bury­ing

a pipe­line too shal­low or not fas­ten­ing bolts tightly enough — is in­creas­ingly a fac­tor con­tribut­ing to pipe­line leaks, fed­eral data sug­gests. Fig­ures com­piled by the Na­tional En­ergy Board show that in the past three years, in­cor­rect op­er­a­tion — which cov­ers ev­ery­thing from fail­ing to fol­low pro­ce­dures to us­ing equip­ment im­prop­erly — has caused an av­er­age of 20 leaks per year. That’s up from an av­er­age of four an­nu­ally in the pre­vi­ous six years.
