What you need to do is think about:
- What are the things that could go wrong?
- Who could be affected?
- How likely are things to go wrong?
- What can be done to stop them going wrong or reduce the consequences?
- Have checks been carried out to be sure that the controls were effective?
Put simply, RECOGNISE, EVALUATE, CONTROL, MONITOR.
For some things there are more detailed legal requirements for assessing risk. The important ones you are likely to come across are:
- Risks from chemicals (COSHH)
- Risks from asbestos
- Risks from lifting and moving things by hand (manual handling)
- Risks from office equipment
- Risk from Fire
Remember, some of the tasks you perform, like ladder work, may not have their own set of regulations but best practice could be buried inside other regulations.
