Not only is fieldwork an essential part of the training of any geologist, it can also be fun for the family. The collecting of fossils can easily distract even the youngest of children for several hours. However, the safety aspects must be emphasised as many people get severely injured or killed around our coastlines and cliffs every year. Some particular hazards include:

Unstable cliff tops, rocks falling from cliffs or mountains, landslips, landslides

Rising tides, large waves, strong currents

It is also important to remember that the locations are not an infinite resource and should be treated in a manner that will allow future generations to have access to them.

The following sites give details regarding safety and fieldwork codes. These are UK guides, the first two of which are relevant worldwide.
