- 9. Definition of Assessmentand Management 9 • Evaluation or estimation of the nature, quality, or ability of someone or something. • E.g. Risk assessment, Educational assessment Assessment • Process of dealing with or controlling things or people. • E.g. Risk management, Financial management Management

- 11. Definition of RiskAssessment 11 The overall process of hazard identification, failure estimation, data gathering and risk determination. What is Risk Assessment
- 12. Five Steps toRisk Assessment 12 Identify the hazard Decide who might be harmed Evaluate the risks and decide on the precautions Record the findings and put them into place Review the risk assessment
- 13. Five Steps toRisk Assessment 13 Step 1: Identify the hazard Walk around your workplace and look at what could reasonably be expected to cause harm. Ask your employees what they think. They may have noticed things that are not immediately obvious to you. Check manufacturers data sheets for chemicals and equipment as they may identify hazards. Look over accident books as they may contain information not immediately obvious to you.

- 17. Five Steps toRisk Assessment 17 Step 2: Decide who might be harmed ❖ For each hazard, you need to be clear about who might be harmed ❖ Don't just think about those carrying out the task. ❖ If the task creates dust or fumes, that could spread to other workers nearby. Consider: -The worker or operators -Adjacent workers -Visitors -Other occupants -Members of the public
- 18. Five Steps toRisk Assessment 18 Step 3: Evaluate the risks and decide on the precautions Can I get rid of the hazard altogether? If not, how can I control the risks? Provide welfare facilities (eg first aid and washing facilities) Issue personal protective equipment (eg clothing, footwear, goggles) Organise work to reduce exposure (eg put barriers) Prevent access to hazard (eg by guarding)
- 19. Five Steps toRisk Assessment 19 Step 4: Record the findings and put them into place A proper check was made You asked who might be affected You dealt with the obvious significant hazards You involved your staff/their representatives in the process
- 20. Five Steps toRisk Assessment 20 Step 5: Review the risk assessments Any significant changes Any improvements that still need to be made Have your workers spotted anything? Have you learnt from accidents?
- 21. Typical Example ofRisk Assessment Process 21 Identify the hazard • Deep drainage excavation in bad ground Decide who might be harmed • Pipelayers in trench Evaluate risks and decide on precautions • High risk of collapse • Use steel trench drag box Record the findings • Fill the risk assessment sheet. Review risk assessment • Monitor site operations and modify risk assessment where necessary. Project: Underground Piping

- 24. Phases of RiskManagement Process 24 Risk Management Risk Analysis Risk Treatment Monitor and Review
- 25. Phases of RiskManagement Process 25 Analyse inherent risk What is the likelihood and consequence of a risk event if it were to occur in an uncontrolled environment? Identify and evaluate controls What existing controls are in place to address the identified risk and how effective are these controls? Analyse residual risk What is the likelihood and consequence of a risk event if it were to occur in the current control environment? Phase 1: Risk analysis
- 26. Phases of RiskManagement Process 26 Phase 1: Risk analysis Risk Condition Action Extreme / High-Risk Serious danger. Immediate action required in this type of risk Medium Risk Moderate danger. Action as soon as possible to implement controls to reduce the risk to as low as reasonably practical Low Risk It may range from minor to negligible danger. Assess if further action can be taken.

- 32. Phases of RiskManagement Process 32 Phase 1: Risk analysis Typical Likelihood Scale: Level Likelihood Description 4 Very likely Happens more than once a year 3 Likely Happens about once a year 2 Unlikely Happens every 10 years or more 1 Very unlikely Has only happened once Typical Consequence Scale: Level Consequence Description 4 Fatality Financial losses greater than $50,000 3 Major injuries Financial losses between $10,000 and $50,000 2 Minor injuries Financial losses between $1000 and $10,000 1 Negligible injuries Financial losses less than $1000
- 33. Phases of RiskManagement Process 33 Phase 2: Risk treatment • Deciding not to proceed with the activity that introduced the unacceptable risk Avoid the risk • Implementing a strategy that is designed to reduce the likelihood or consequence of the risk Reduce the risk • Implementing a strategy that shares or transfers the risk to another party or parties Share or transfer the risk • Making an informed decision that the risk rating is at an acceptable level or that the cost of the treatment is low Accept the risk
- 34. Phases of RiskManagement Process 34 Phase 3: Monitor and review • Ensuring that controls are effective and efficient in both design and operation • Obtaining further information to improve risk assessment • Analysing and learning lessons from risk events • Identifying emerging risks.

- 38. Summary 38 The goal ofrisk management is to take corrective actions to reduce the impact and likelihood. The impact can be reduced by controlling the sources from which they arise and instituting limits to the exposures. There are some risks that cannot be either eliminated or transferred and must be absorbed by the organization. To manage the risks, we have to establish a good bondage between all team members. Risks are not always negative and it is an opportunity to develop a project in a better way with good outcome.
