3 KEY JOB STEPS WHAT ARE THE HAZARDS? WHAT COULD GO WRONG? Product leaking to grade Slips, trips & falls Environmental damage WHAT CONTROLS WILL PERSON RESPONSIBLE BE IMPLEMENTED? Name Initial Ensure drip trays are used when breaking flanges All spills to be cleaned immediately Pinchpoints and sharp objects Crush injury and / or cuts Identify and discuss location of pinchpoints and sharp objects keep fingers/hands clear Wear appropriate gloves Manual Tasks Back injury & strains Use correct lifting aid wherever possible. to lift large spades/blanks Lift using correct techniques Regular stretching Incorrect Spades/blinds & gaskets used Failure of spade/blind or blown gasket causing personnel injury or equipment damage Check all spades/blinds/gaskets are correct size & rating according to blinds list. Spiral wound gaskets to be use for blinding. Flanges misaligned/gasket faces in poor condition Equipment damage, injury to personnel and equipment Ensure all blinding performed to Santos flange break procedure Mac tag to be used Untidy worksite Slips/trips Keep area clean/organised at all times EHSMS09.1 Appendix A JHA Form Revision 1 Page 3 of 5

4 Remember: EVERYONE has both the authority and responsibility to STOP THE JOB if there is any doubt about the safety of the operation. Lessons Learned (This is done after the job, in order to identify any improvements to this JHA, Procedures or the JHA process) Should a Standard Operating Procedure (SOP) be developed for this task? Yes No Recommended improvements: Reviewed By: Review Date: EHSMS09.1 Appendix A JHA Form Revision 1 Page 4 of 5

5 Hazard Checklist Have you controlled the top 5 causes of injury at Santos? Manual Tasks Pinchpoints Injury from Tool Slips and Trips Hit by Moving Object A hazard is a source of energy that has the potential to cause harm, ill health or injury, or damage to property, plant or environment. Does the job step you are about to do involve energy sources that need to be controlled? If you tick yes for any of the hazards below, please list them on the JHA form and detail how they will be controlled. Energy Source Yes No n/a Energy Source Yes No n/a Physical Electrical Chemical Radiation Pinchpoints Animals Moving Objects Toxic Plants Moving People Viruses Falling Objects Biological Bacteria Hot Surfaces Fatigue Moving/Rotating Parts General Health Pressurised Systems Intoxication Slip/Trip Depression AC/DC Power Psychological Mind on the Job Static Electricity Reaching Lightning Stretching Hazardous Substances Bending Dangerous Goods Lifting / Carrying Poisons Pushing / Pulling Harmful Gases Loosening / Tightening Fibres / Dusts Sitting Radiant Heat Ergonomic Standing Sun Ultra Violet Radiation Hot / Cold Weather X-Rays Winds Lasers Dust Naurally Occurring Radioactive Materials (NORMS) Ionising Radiation Environmental Currents Storms Earthquake Hierarchy of Control When selecting your controls, work through the hierarchy of control model. Controls in this model are listed from most effective to least effective. Aim to select the most effective control possible for hazards in your work tasks. 1. Can you Eliminate the hazard? (e.g. use mechanical device to eliminate manual lifting requirements) 2. Can you Substitute the hazard with another tool? (e.g. use low voltage instead of high voltage power tool) 3. Can you apply Engineering solutions to control the hazard? 4. Can Administrative procedures control the hazard? 5. Can Personal Protective Equipment (PPE) control the hazard? (e.g. guards, barriers, hydraulic tools, toolbox lid braces) (e.g. training, stepback, first aid equipment, journey management plans) (e.g. gloves, safety glasses, safety harness, respiratory equipment) EHSMS09.1 Appendix A JHA Form Revision 1 Page 5 of 5
