Hi Scott The HSE have produced a guidance document on lone working - http://www.hse.gov.uk/pubns/indg73.pdf - mainly it is down to the emlpoyer to consult and carry out a risk assessment to see if the tasks performed can be carried out safely by a lone worker and/if there are specific steps needed to ensure their safety. From this risk assessment you may then need to look at specific measures for this worker, which could include some or all of the above. I would also recommend you ensure any health or medical issues are sorted out. There is no particular legislation - covered by HASWA and the requirement to assess risks. Ian

Hi Eddie. My thoughts on signs are that they will not be read or complied with if more than a handful of words appear, particularly if the person expected to read them is driving (or not able to read!) and not familiar with the route. If they are a regular to the site they will be blasé about notices anyway. One to one instruction on arrival may be a better approach.
