Project success depends largely on the ability to positively change people’s attitudes and behaviour. Change management initiatives need to be carefully planned. They do not happen by chance.
During maintenance it is important to take every possible precaution to avoid loss or harm. One important precaution is to isolate all the equipment being worked on from uncontrolled energy sources. Positive isolation should be used where possible and controlled by a system of locks managed by the permit to work.
Shift handover is a a critical process that relies on effective communication in order to reduce the risk of safety incidents. The permit to work system must be coordinated with the shift handover procedures to ensure that jobs continue to take place under safe conditions, even when teams change.
Work at height is a particularly hazardous activity which should be reduced by specific control measures that first tries to avoid the work altogether, and then if this is not possible, limits the risk through precautions. The permit to work is an important administrative tool to ensure safe work takes place at height.
This case study describes a recent project where an electronic permit to work system (IntelliPERMIT) was implemented at a bauxite mine and the associated alumina refining operation in Australia.
Simultaneous operations (“SIMOPS”) refers to a situation where two or more potentially conflicting activities are being executed simultaneously and in close proximity to one another. Safety is affected because the interactions between the jobs are not fully understood.
