what are the requirements for workers who normal hours are day time, say 8 - 5, but may have a need to work during the evenings in the office on their own?

Agreed that your provisions will largely depend on the outcome of your risk assessment. To use my place as an example, we are an office based business but have people working through the night, including cleaners, print room staff, IT support and so on. We have a 24 hour security presence who are all first aid trained, and carry out hourly sweeps of the building. We also inform all staff of out of hours arrangements and regularly refresh this, and carry out an annual evening evacuation drill. We do other things too, but hopefully this gives you an overview.

The assessments have been done, including loan worker. The normal business hours are 8-5 and occasionally some people have to come in to work in the evenings or may be called in, e.g. I.T. over night. We don't have onsite security all night so no first aid and obviously no fire marshals.

Chris Burns, sometimes our colleagues ask for advice, because they perhaps need support or encoragement that they are headed in the right direction. I for one, found the support on this forum invalable during my training years. J Watts - how far is your office from a medical establishment? Do you have a lone worker 'checking - in /buddy' procedure? Is it absolutely necessary for staff to work at the office, can they work from home? My I.T. guys are EFAW trained to a minimum to cover just such an occasion as being called in. Hope this helps.

F Brown - two shots across my bows eh, I must have struck a chord or something? I too have gained lots of useful advice by using this discussion forum, it's just in this instance I don't see how much further we can go. If risk assessments have been done surely there comes a time when people have to stand up and be counted and make a decision. Your reference to lone worker buddy should have been covered by the good quality lone worker assessment that we are informed has been carried out. I don't think working from home applies here according to the information provided in the first instance.

Yes you need to risk assess but that's not what you asked for is it, you asked for ideas! If it is a couple of people working in an office out of hours then a first aider isn't necessarily required (bear in mind HSE's guidance on small numbers of employees in a low risk environment). It's an office so we have to assume the ability to phone out for assistance and as long as there is a first aid kit. The same for fire, a low number of employees is not going to mean mass evacuaton. As long as those employees have been trained in the procedures then that should be ok. Would be ideal to have a check of who is in the building (signing in book?) and who evacuated but that isn't always practicable. I assume it would also be inpractical to have a check in system for people working late. Lets face it up and down the land people working in office stay late. So yes RA but for me there would need to be limited additional procedurees due to the low risk.
