straight forward health and safty advice 
It is important that an adequate risk assessment is made of any activity that may involve ‘lone working’ and that ample workplace precautions are put into place Lone workers are those who work by themselves without close or direct supervision, they may be in a fixed establishments, or be mobile workers working away from their fixed base; however wherever they are, they should not be put at more risk than other employees. Solitary workers face particular problems. If a person has to work alone, it is essential that they tell their direct supervisor where they will be working and how long they expect their work to take. When they have finished the work, they must tell their supervisor so that they know that they are safe. Additionally, if working in an office or workshop in another business's premises, then advise the someone that they are on site when you arrive; and make sure that they know where they will be working; tell them the expected time of leaving; check the emergency arrangements for the site,; and tell the same person that they have finished before leaving site. When working alone, no one must expose themselves to more risks than they would if they were working with others, and must only handle substances and goods that can be safely handled by one person. People working alone make sure there is safe access and exit to and from the workplace, and know the location of fire fighting equipment, first aid equipment and how to escape from the area they are working in an emergency. Modern technology is overcoming some of the problems associated with lone working by providing remotely monitored ‘man-down’ and ‘no-response’ systems. Businesses now offer GPS location tracking and reporting with automated check-in systems, which call lone workers on their mobile phone, or other wireless communication device, at predetermined intervals that are set by the worker over the phone.
