There are many injuries that could occur in an agricultural environment. Farm workers tend to work very long hours on a farm, doing very labour-intensive work. This can lead to fatigue and tiredness. If it is hot and dry outside, then it will also be very easy to become dehydrated. If you overwork, then you could collapse, or flare up pre-existing medical conditions.
Farmers may also use chemicals in an agricultural space, which could lead to burns or poisoning if handled incorrectly. Then, there are the tools that farmers work with; very large and heavy machinery that is often incredibly sharp. This can lead to life-threatening cuts, bleeding, and shock. There are also often animals on a farm, that could bite and attack agricultural staff.
