2012 IEHF - Task risk management

  1. 1. Tel: (+44) 01492 879813 Mob: (+44) 07984 284642 andy@abrisk.co.uk www.abrisk.co.uk 1 Task Risk Management A Process for Managing Risks with Task Analysis at its Heart Andy Brazier
  2. 2. 1. Identify tasks Possible approaches Skip the step – people often want to dive straight into task analysis Existing procedures – assume they cover all tasks Structured brainstorming – process drawing 2 Filters Duty/standby Pumps Duty/standby DP Alarms Lo LoLo Hi Trip Storage tank Delivery tanker Group exercise
  3. 3. 1. Identify tasks This step is very simple – but encourages a systematic approach Uses for task lists ‘Gap analysis’ of procedures, training/competence systems; ‘On the job’ training programmes; Workload estimates; Managing organisational changes. 3
  4. 4. 2. Prioritise tasks for analysis Possible approaches ‘Gut feel,’ experience or ‘normal’ risk assessment HAZOP, Process Hazard Review (PHR) etc. Scoring system (see OTO 092 1999 – HSE) 4 Hazardousness of system Ignition/energy sources Changing configuration Error vulnerability Impact on safety devices Overall criticality Low Medium High 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 0-3 4-8 9-15
  5. 5. 2. Prioritise tasks for analysis Benefits of scoring tasks at stage 2 Objective Demonstration of why tasks were selected for analysis – safety reports/cases Highlight ‘anomalies’ without carrying out a detailed task analysis 5 Microsoft Excel Worksheet
  6. 6. 3. Analyse the most critical tasks Task analysis is tried and tested – but negative perceptions Time and effort Only doing it to keep the regulator happy Discoveries from every analysis - if done ‘properly’ 6
  7. 7. 3. Analyse the most critical tasks Group exercise – use a data projector People share experiences and concerns Accept procedure may not reflect reality Buy in to new methods An excellent training exercise for people involved Human error analysis Look at the task with ‘new eyes’ Identify where issues have been ‘glossed over’ 7
  8. 8. 4. Use the findings ‘Engineer out’ error potential New projects – human factors integration plan Design reviews and system modifications Procedures High criticality – print, follow and sign every time Medium criticality – reference procedures Low criticality – generic procedures and guidance How do you manage the risks the risks of critical tasks that are performed frequently? Competence system How to perform tasks Understanding the risks 8
  9. 9. 4. Use the findings Continuous review – proactive and reactive Consider all stages when examining failures 1. Why is a task missing from the list? 2. Why was criticality not assessed correctly? 3. Was the task analysis correct? 4. Were the findings used? 9
  10. 10. Close Task risk management = a four stage process 1. Develop a task list 2. Prioritise task analysis according to criticality 3. Analyse the most critical tasks 4. Use the findings 10
