The cause of the ammonia leak at Westhills Arena last week falls onto a faulty racheting  wrench.

When employees of Accent Refrigeration were beginning to release some of the ammonia from the arenaB次元官网网址檚 system, a faulty tool inhibited the connection between the hose and tank to be tightened.

The ammonia was being transferred into cylinders because there was more ammonia in the system than needed, said Art Sutherland, owner of Accent Refrigeration.

B次元官网网址�(The employee) wasnB次元官网网址檛 able to close the cylinder and when an other employee came back with another wrench, there was too much ammonia to close it,B次元官网网址� Sutherland said.

B次元官网网址淎ll of the wrenches have been replaced and weB次元官网网址檝e put other steps in place to prevent it from happening again ... We have a dedicated ammonia soaking hose now.B次元官网网址�

B次元官网网址淭his was just an unfortunate set of circumstances,B次元官网网址� said Langford administrator Jim Bowden. B次元官网网址淏ut, we were able to test the evacuation process and the first responder process and everything there went well.B次元官网网址�

The day before the leak, the crew had successfully released 400 pounds of ammonia from the system. On Nov. 30 they were attempting to release another 100 pounds, said Bowden.

No one was injured during the leak.

The leak was detected shortly after 8 a.m., all roads and pathways leading to City Centre Park were blocked off until about 11:30 a.m.

Businesses in the area were evacuated as well as some residents on Jenkins Avenue.

CCP reopened at 2 p.m.

West Shore RCMP, several fire departments, Capital Regional District Hazmat team and BC Ambulance were on scene.
