The week before the wedding, the MD wants to make sure that all of the gardens around the hotel look neat and tidy. While walking around the gardens they notice that the two, large, identical hedges on either side of the hotel driveway need cutting. They return to their office and call the head gardener ( HG ) , who works at the hotel for two or three days each week. The MD asks if they can come to the hotel the following day to cut both of the hedges before the wedding at the weekend. The HG , eager to please the MD , says that they should be able to . The following morning it is already warm. The HG arrives early and collects the old petrol – powered hedge trimmer and the recently – purchased leaf blower from the storage shed, along with some petrol. The HG has worked at the hotel for over 2 0 years. The hotel recently recruited an assistant gardener who is still being trained and is not yet authorised to use some of the tools, such as the hedge trimmer. The assistant gardener is 1 9 years old and attends college two mornings a week, including this morning, so the HG will have to start the work on the hedges alone. The hedge cutting is usually done during the warmer months, so it has been a while since the hedge trimmer was last used. However, the leaf blower gets used all year. The HG is pleased that today the weather is dry for the hedge cutting. They remember that last time these hedges were cut, it was a cold, wet day. The HG decides that there is time to smoke a cigarette before making a start on cutting the two, large, identical hedges. As the HG is working on their own this morning, they decide to use the hedge trimmer for about half an hour and then swap to the leaf blower to clear up the cuttings from that section of the hedge. They will then go back to using the hedge trimmer on the next section of the hedge. This pattern of work is continued throughout the morning. By lunchtime the HG is feeling quite tired but pleased, as they have managed to cut all of the hedge on one side of the driveway and tidy up . They have used the hedge trimmer for about two and a half hours, and the leaf blower for about 5 0 minutes, with a 1 5 – minute break for a drink and another cigarette. The assistant gardener arrives at the hotel from college during the lunch break, and is very excited to tell the HG what they have learnt that morning about vibration exposure. The HG is eager to get on with the afternoon ’ s work, which is to cut the identical hedge on the other side of the driveway. The HG will do all of the afternoon ’ s hedge cutting; they expect this will take the same amount of time as the morning ’ s work. The assistant gardener will do all of the clearing up using the leaf blower; they are not as fast as the HG and the clearing up with the leaf blower takes them about an hour and ten minutes.
