I am slightly confused by your request. My advice would be to look at the over all number of tasks as units that have to be completed. Risk assess the known tasks either as a stand alone task or as a number of tasks needed to work on a complete system. This may reduce the process.
It is possible to look at the tasks that an individual may need to carry out and then tag these against that position. You can then create a risk assessment log that will identify safety criticial tasks and then high, medium and low risk tasks.
You need to firstly ensure that the person/s carrying out the assessments are competent.

It is then very important that the staff carrying out the work are suitably trained to ensure that the risk controls are part of the system of work. You may need to do some sort of job safety analysis as a starting point to identify the critical tasks.
At the end of all this you will need to demonstrate a clear link between each post, the work they carry out and the related risks assessments and controls for that work.
The process for informing the worker about the risks and controls is very important and this can be merged completely into the training and safety briefing process.

I hope that this helps.
