We have ours on a company intranet system, which every employee within the company has access to.

I remember in my waste days before I went into H&S, reading through reams of risk assessments, not sure I could remember many of them now or even back then!

An important note to remember. You do not need to force you staff to read the whole risk assessment, only inform them of the significant outcomes of it. Risk assessment records are usually technical documents that do not lend themselves to easy reading. A company H&S handbook is normally a better bet as you can lay out the hazards and controls in a more user friendly format with photos, etc. The handbook by itself is unlikely to be effective either, you will need to combine it with adequate training etc.

Dynamic risk assessment for bin men is essential, but given the number of collections made in a day I could not see the value of trying to record them all. Train the guys on hazard awareness is about all you can do. We were introducing site specific risk assessment for commercial customers when I left the industry a few years back. The intention was to have notes on the driver's information screen for each job that would point out any significant hazards he needed to be aware. Need to have good IT in the cabs for that though.
