Note: You should support your answer, where applicable, using relevant information from the scenario.

Scenario

Fieldworker A Meanwhile, fieldworker A arrives and parks as close as possible to the first site where they need to take a sample. They have started with the site furthest away from the facility, and intend to work their way through the jobs back towards Lab 1, delivering all the samples when they have finished. At this first site they will have to walk about 1km to the sampling point. Fieldworker A starts walking down a rough track. After a few minutes walk the path has ended and fieldworker A is walking across a rocky terrain covered in slippery moss and grass. The sampling point is further up the hill in front of them, in a small, wooded area. As they keep walking it starts to rain. Fieldworker A is used to rain from their cross-country running, so carries on walking. After a few minutes, fieldworker A arrives in the wooded area and starts looking for the natural spring. After some time, fieldworker A still cannot find the sampling point. They get their phone out to check the location again from the job details. They notice that it is now 14:30, but they do not have a phone signal. Eventually, they find the natural spring and take a sample. As they come out of the wooded area it is raining even harder and it is very dark. As they clamber over the rocky terrain they slip, falling to their knees. Fortunately, they only bruise their knees. When fieldworker A gets back to the car, they check their phone; they have a very weak phone signal, but they have several missed calls from the FWM.
