2 What I will cover Introduction

3 What I will cover Introduction How do we control the risks

4 What I will cover Introduction How do we control the risks Interaction with the HSE

5 What I will cover Introduction How do we control the risks Interaction with the HSE Review of processes and practises

6 What I will cover Introduction How do we control the risks Interaction with the HSE Review of processes and practises How can I record vibration and what kit is available to help me

7 What I will cover Introduction How do we control the risks Interaction with the HSE Review of processes and practises How can I record vibration and what kit is available to help me All of it will merge / crossover to a degree as I go along

8 Introduction Extensive Policy, Process and Practise documentation in place

9 Introduction Extensive Policy, Process and Practise documentation in place Medical Surveillance Pre-employment assessment prior to undertaking vibration work and joining a Closed User Group (CUG) Annual surveillance where all CUG members complete a short self assessment Qualified person assessment for CUG members describing symptoms from above to quantify the problem Diagnostic assessment (first time or worsening) formal diagnosis and advice on further management Specialist standardised testing for CUG members suspended on health grounds relating to vibration exposure

10 Introduction Extensive Policy, Process and Practise documentation in place Medical Surveillance What could go wrong?

11 Introduction Extensive Policy, Process and Practise documentation in place Medical Surveillance What could go wrong? Nothing

12 Introduction Extensive Policy, Process and Practise documentation in place Medical Surveillance What could go wrong? Nothing But it did letter from HSE

13 How do we control the risks Equipment

14 How do we control the risks Equipment Reviewed by Chief Engineer s Team / Safety Team Fit for purpose Arrange any risk assessments or reviews

15 How do we control the risks Equipment Reviewed by Chief Engineer s Team / Safety Team Choose low vibration equipment (new or replacement)

16 How do we control the risks Equipment Reviewed by Chief Engineer s Team / Safety Team Choose low vibration equipment (new or replacement) Brought in through our Supply Chain

17 How do we control the risks Equipment Reviewed by Chief Engineer s Team / Safety Team Choose low vibration equipment (new or replacement) Brought in through our Supply Chain Manager records equipment on esitest

18 How do we control the risks Equipment Reviewed by Chief Engineer s Team / Safety Team Choose low vibration equipment (new or replacement) Brought in through our Supply Chain Manager records equipment on esitest Checked via esitester Accredited supplier where appropriate esitester checks compliance certification

19 How do we control the risks Equipment Individual Trained on use / restrictions for equipment Active Monitoring System (safety checks) Closed User Groups Medical Surveillance as appropriate

20 How do we control the risks Equipment Individual Trained on use / restrictions for equipment Active Monitoring System (safety checks) Closed User Groups Medical Surveillance as appropriate This is where it had gone wrong

21 How do we control the risks Equipment Individual Trained on use / restrictions for equipment Active Monitoring System (safety checks) Closed User Groups Medical Surveillance as appropriate This is where it had gone wrong Change of supplier

22 How do we control the risks Equipment Individual Trained on use / restrictions for equipment Active Monitoring System (safety checks) Closed User Groups Medical Surveillance as appropriate This is where it had gone wrong Change of supplier Told to report condition (again) under RIDDOR

23 Interaction with the HSE Provide copies of all our documentation Policy / Processes / Practises Risk Assessments including Generic Risk Assessments (GRA)

24 Interaction with the HSE Provide copies of all our documentation Discussed our training arrangements, in particular R2L Active Monitoring System (AMS) Safety Checks

25 Interaction with the HSE Provide copies of all our documentation Discussed our training arrangements Agreed to review above again with focus on Poling Work Update risk assessments Create new task related GRA Points system to be added HSE would be Happy

32 Review of processes and practises Tools and equipment Review tasks Speak to manager Speak to engineer Paper record Time HAVI record Points

33 Review of processes and practises Tools and equipment Review tasks Revised Task GRA The exposure calculations in each of the scenarios were carried out using the HSE Hand-Arm vibration Calculator, downloadable from the HSE website. Manual erection of a DP pole, difficult conditions, no stay anchor required, chain saw used to cut up pole. (3 man team) This scenario looks at the situation where it is not possible to use the PEU (Pole Erection Unit) to erect the pole. The ground conditions are such that the road breaker is used for up to one hour to break through a concrete top surface, followed by a manual excavation of the pole hole. Following the erection of the pole, a maximum of six drop wire fixings per person have to be renewed. When the drop wires have been transferred to the new pole, the old pole has to be recovered by cutting it up on site with a chain saw. Vibration Magnitude Time to reach EAV 2.5 m/s 2 A(8) Time to reach ELV 5 m/s 2 A(8) Partial exposure Exposure duration Tool or process m/s 2 rms Hours Minutes Hours Minutes Hours Minutes m/s 2 rms Use of Road Breaker Use of power drills to fix drop wires to walls Use of chainsaw Daily exposure m/s 2 A(8) Exposure Points Total Exposure Points
