Suggest a range of measures that F&D could put in place to get a more accurate assessment of vibration exposure of workers carrying out similar work to that at Marshes Road Note: You should support your answer, where applicable, using relevant information from the scenario and mail conversation 5 Valid Points required. Scenario:- Find & Dig (F&D) A week later, November 6 is a very cold morning when F&Ds workers arrive at the site on Marshes Road. Worker X is going to begin with operating the hand-held percussive breaker (breaker), so they put on the required PPE including hearing protection and eye protection, as well as steel toe-capped boots. Meanwhile, worker Y is unloading the breaker and setting it up ready for worker X. Workers X and Y are concerned that worker Z will be absent this morning, as worker Z is the most experienced member of the team, having spent many years working for several organisations that do this type of work. Workers X and Y feel under pressure as they know that workers from WWA will be coming to the site soon. Workers X and Y will share the use of the breaker equally to remove as much of the road material as possible. After this, they will change to hand digging as they get close to the water pipe. Around 11:15 the WFM from WWA arrives on site, and has to wait for the digging to be completed before they can inspect the water pipe and take samples back to the lab for testing.

It will just be two of our people (workers X and Y) on site at Marshes Road today doing the digging. The other team member (worker Z) has had to go to a doctors appointment (it is something to do with a sore elbow or arm they said). It is not a problem as the two of them should be able to get the job done. So I suggest your people delay coming to site until mid-day.

I have looked at the helpful information in the HSE L140 document on typical vibration magnitudes. I just wanted to check where the information you sent came from. Please could you let me know so I can confirm the risk assessment is approved before Monday. Many thanks. From: F&D Manager Sent: Thursday, November 2, 2023, 10:30 To: WWA Fieldwork Manager Subject: RE: Work to uncover water pipe for inspection and sampling at Marshes Road Morning Yes, sorry I forgot to put that in the risk assessment. I recall this is 7m/s2. I hope that is what you wanted to know. Regards From: WWA Fieldwork Manager Sent: Tuesday, October 31, 2023, 14:55 To: F&D Manager Subject: RE: Work to uncover water pipe for inspection and sampling at Marshes Road Hello Thank you for confirming the start time for Monday. Thanks also for the risk assessment and method statement. I had a look at the detail in the risk assessment and noticed it had limited detail on vibration risk. I know when we spoke you said you would be using a breaker for most of the road excavation, changing to hand digging when close to the water pipe. Please can you confirm the make, model and vibration magnitude for this breaker and add this to your risk assessment. Many thanks From: F&D Manager Sent: Tuesday, October 31, 2023, 13.30. To: WWA Fieldwork Manager Subject: Work to uncover water pipe for inspection and sampling at Marshes Road Morning Just to confirm we are ready to start on site at 08:00 next Monday. I am putting our best team of 3 (workers X, Y and Z) on this job so I am confident this should run smoothly. You should already have the method statement and risk assessment. As discussed, the plan is to dig up the road in two places in order to give your people two sites for inspection. We estimate it will take 3 hours to complete the job. I suggest that your people come to site around late morning when the work will be almost complete, and the pipe should be nearly ready for inspection. Regards
