I am really lucky as my employer (none nail related) has asked me to do a St Johns First Aid day course, which will come in handy...
However I really dont know where the law stand on freelance workers, I found this on the HSE web site.
Application of the Health and Safety (First-Aid) Regulations 1981 to self-employed workers
As a self-employed worker, you are required to ensure you have adequate facilities to provide first aid to yourself while at work.
You must make an assessment of the hazards and risks in your workplace and establish an appropriate level of first aid provision. What this means in practice is that if you work in a low risk activity, eg clerical work at home, a normal domestic first aid box would be adequate. If your work involves driving long distances or you are continuously on the road, the assessment may identify the need to keep a personal first aid kit in your vehicle.
Many self-employed people work on mixed premises with other self-employed or with employed workers. Although you are legally responsible for your own first aid provision, it is sensible to make joint arrangements with the other occupiers and self-employed on the premises. This would generally mean that one employer would take responsibility for first aid cover for all workers on the premises. HSE recommends there is a written agreement for any such arrangement.
Which applies to us but not sure how it effects our cleints?
