From BGV D36 to BGI 694

The previous German accident prevention regulation BGV D36 was replaced in 2008 by BGI 694 – “Handling instructions for the use of ladders and steps”.

It can be downloaded from the homepage of the Verband Deutscher Leitern- und Fahrgerüstehersteller (VDL) at www.leiternverband.de.

Our catalogues also takes account of the technical information relating to the new distinction between “reach heights” and “working heights”.

What size is required?

 

When selecting the size/length of ladder, it should be ensured that

• leaning ladders which are not additionally secured are only used up to the fourth highest step/rung as otherwise there is a danger of them slipping away
• double-sided freestanding ladders are only used up to the third highest step/rung so that a sufficient hold is possible
• combination ladders used in the "freestanding ladder with mounted extension ladder" position are only used up to the fifth highest rung
• the size of freestanding ladders with a platform is selected in such a way that the user can reach the maximum required working height from the platform without stretching

 

Reach height:

• BGI 694 defines the reach height as the height which can be reached from a calculated standing height – according to the type of ladder. This is approximately 2.00 m above the
• standing height.

 

Working height:

• Working height refers to the range for working at body height, e.g. with a drill. To take account of the working heights of different industries, an average working height of 1.50 m above standing height is assumed in our catalogues.

 

This definition gives rise to a simplified formula*

• Standing height + 1.50 m = Working height
• Standing height + 2.00 m = Reach height

* This may vary depending on the type of ladder. Please observe the information in the technical tables in our catalogues.
