Stanley/Safety Knife assessment will be required, manual handling, lone working in premises not owned by the company, violence / attacked etc, checking in, first aid at work. Dont know if the business includes warehousing but if it does then PAS 79 Fire risk assessment may be handy: -http://www.fia.uk.com/filemanager/root/site_assets/technical/pas_79_drs.pdf just some that spring to mind, COSHH is usually one for most businesses also.

Hi, Please take this reply in the spirit it is intended. If there are 5 or more employees your friend should have access to competent health and safety advice. By virtue of the fact that you are asking these questions it is apparent you aren't a competent health and safety advisor. However the risk assessment should identify all the hazards and the control measures required to remove or minimise them as far as is reasonably practicable. To allow the assessment to be of any value it is something that needs to be done by your friend and someone who can competently assist. Consider hazards such as: Manual Handling, sharp tools, hazardous substances (glue - COSHH assessment), asbestos (existing floor tiles), protection of the tenant (slips, trips), dust...and anything else he thinks is hazardous.

Remember also that the HSE web site has information that can help evidence any risk assessment and to suggest a range of control measures that you can consider. Any competent advice as suggested by DNW would have those tools in hid armoury.
