There are many formal techniques available to fully qualified risk assessment professionals. These are not techniques that you can just pick up and use with no background or training in the subject area. If you do, and the documentation is pulled by an accident investigator (with skills in this area) or by the Police investigating a potential crime, then you might be in for a shock.
For example, you post starts with "hazard identification" and then goes on to "report hazards". These are completely separate areas. PM me for more real information. Oh, and I am professionally qualified in this area!
