Hot work (Cutting ,Grinding,welding ) in running process plants needs stringent safety risk assessment and adequate risk mitigation plan compared to non process geographical location in an organization.
How to ensure Zero safety risk in process plants ?
1.Ensure proper barrication all around the hot work location with high temperature resistant materials/blankets in a manner that no weld splatters or hot materials come out from the barrication.
2.Ensure breathing opening at one of diagonal top corner opposite to hot work location in form of chimney of suitable height . This is required for ease of welder /grinder doing work.If the hot job is being done at pipe rack area,ensure there is no unsafe conditions just below the work location.Remove oily waste/plastics waste if any .
3.If grinding work is performed ,ensure that maximum allowable grinding wheel speed (RPM) is always more than grinding machine RPM.
4.Check the direction of rotation of grinding wheel.Ensure that position of grinder is such that hot spatters does not spread or fly due to centrifugal force towards the chimney side.
5. Ensure zero- LEL near by work location continuously.
6.Job should be executed by competent personnel only.
