Below is detailed risk assessment and job safety analysis for testing and commissioning of booster pumps.
Risk Assessment will be reviewed and updated based on site conditions and after any major incident.
The most common form of risk assessment is to examine a hazard and possible consequences of exposure to that hazard and the likelihood of that particular Impact / consequence eventuating.
This risk assessment result is called as risk level.
By using Risk Assessment Matrix evaluate the quantitative risk analysis where numerical data is used.
Risk Rating:
1 – 3 Low
4 – 6 Moderate
8 – 12 High
15 – 25 Extremely High
