12 Safe Maintenance Rules HAZARD ISOLATIONS

August 6, 2015 | 2 To protect the persons who intervene on a facility, to be sure of the energy absence (electricity, fluids, chemicals and mechanics) The incidents linked to an isolation absence are not numerous but are generally of a strong severity This is an essential step in both the workplace and at home WHY THIS RULE? HAZARD ISOLATIONS

August 6, 2015 | 3 RULE DEFINITION HAZARD ISOLATIONS When performing a task on a powered or pressurized system ensure that isolations have been validated by the exploitation team and double check all isolations are in place as per the isolation plan.

August 6, 2015 | 6 Check isolations prior to working on any powered or pressurized system Isolation protects people and facilities against the consequences of: electrical, mechanical energy and pressure energy risks Wear all prescribed PPE PPE is my last layer of protection against electrical risk. PPE is provided by Dietsmann and must be kept in good condition. I MUST HAZARD ISOLATIONS

August 6, 2015 | 7 Perform an absence of power and/or pressure test prior to starting my task To be sure of the energy absence: electricity, fluids, chemicals and mechanics Ensure that the electrical rescue kit is available in the electrical cabinet The kit consists of: a pair of insulating gloves, insulating stool, insulating pole and insulating rug. A safety poster with what to do in case of electrocution is located on the door I MUST HAZARD ISOLATIONS
