The Permit Holder was performing the physical work instead of maintaining effective supervision of the work team as required by the permit process A shortcut was taken by attempting to remove the belt using a screwdriver instead of first releasing the belt tension through the designed adjustment process. An inappropriate tool was used for the task, creating a pinch-point hazard and increasing the likelihood of a sudden release of stored energy. The HVAC method statement and risk assessment did not adequately identify the hazards associated with belt tension release and replacement activities Over-reliance on experience and familiarity with the task resulted in poor hazard recognition and acceptance of unsafe work practice
