Managing and assessing risk is about identifying the significant hazards and putting adequate controls in place.
As an employer or duty holder you are legally obliged under the Management of Health and Safety at Work Regulations 1999 to carry out a risk assessment of the significant risks in your workplace or business.
Where there are five or more employees a record of these assessments should be kept.
The Health and Safety Executive (HSE) has produced a number of tools to assist you in doing this and provides guides, example risk assessments and checklists to help.
You will also need a health and safety policy which details how you will manage health and safety in your workplace.
