Use of Step LaddersUse of Step Ladders

For a short vertical distance Where access will be infrequent

When the user will not need to carry

anything Only one user will need to use it at atime

It will not be needed for evacuatinginjured people

The structure of the machine makes itimpossible to use steps

Annex IAnnex I General principlesGeneral principles

The manufacturer of machinery or hisauthorised representative must ensure that

a risk assessment is carried out in order to

determine the health and safetyrequirements which apply to the machinery.

The machinery must then be designed and

constructed taking into account the results

of the risk assessment

Machinery must be designed and

constructed in such a way as to allow

access in safety to all areas whereintervention is necessary during

operation, adjustment and maintenance

of the machinery

High level access risksHigh level access risks

Can be foreseen at an early stage inthe design process

Possible to eliminate or minimiserisks at the design stage

More difficult to minimise once the

budget has been fixed or the

equipment has been delivered
