It is good practice when working alone to put some additional safety measures in place. As a minimum you should inform someone of where you are going, and your return time. (What3words.com is a useful website to give someone an accurate location). A ‘buddy system’ of regular ‘check in’ phone calls with a family member or colleague may also be appropriate if you are working alone for extended periods. In the event that you fail to get in contact, then your contact should know the steps to take in order to locate you or if necessary raise the alarm with the emergency services.
