Railing Guidelines - Head Protection Catch Point and Climbing Prevention

Just take a look at the requirements according to § 3 LBOAVO yourself.

Thank you very much! That's exactly what I needed.

Can you help me break this down further?

(5) Openings in guardrails according to paragraph 1 may, on surfaces where the presence of children up to six years old must generally be expected,
1. with a horizontal arrangement of the railing elements up to a height of the guardrail of 0.6 m, be no higher than 2 cm, above that no higher than 12 cm,
2. with a vertical arrangement of the railing elements be no wider than 12 cm,
3. in the case of irregular openings, not facilitate climbing and not be larger than 12 cm in any direction.
In our case, regular visits by children are not even remotely to be expected, so I also do not see any restrictions on the spacing of the balusters. Correct?

The distance of these guardrails from the area to be secured must not exceed 12 cm when measured perpendicularly. Sentences 1 and 2 do not apply to residential buildings of building classes 1 and 2 and to apartments.
What does that mean exactly?

I know everything is questionable, but I would like to clarify the situation here: what is allowed and what is not?

In general and regularly are two different aspects. The presence of children under 6 can generally be excluded in data centers, chemistry laboratories, or crematories. Can you safely exclude that a child will ever visit you?

Can you definitely rule out that a child is ever visiting you?

Okay, I certainly cannot. The sentence here: Sentences 1 and 2 do not apply to residential buildings of building classes 1 and 2 and to apartments. in conjunction with this explanation: 3. What is meant by building classes 1 to 3? The classification of building classes can be found in § 2 para. 4 of the State Building Code: - Building class 1: detached buildings with a height of up to 7 m and no more than two usage units with a total of no more than 400 m² - Building class 2: buildings with a height of up to 7 m and no more than two usage units with a total of no more than 400 m² - Building class 3: other buildings with a height of up to 7 m Note: With regard to length and width or floor areas, there are no restrictions for building class 3! Height within the meaning of the definition is the measure of the upper edge of the floor of the highest storey in which a habitable room is possible, above the average ground surface. Our house is without a cellar from the raw floor to the ridge 6.9 m high...

Unfortunately, I can no longer change the post...

But does that mean that even if sentences 1 and 2 are excluded by the definition of the building class, 3. still applies and states:
3. bei unregelmäßigen Öffnungen das Überklettern nicht erleichtern und in keiner Richtung größer als 12 cm sein.

Does that mean that the distances must not be greater than 12 cm either horizontally or vertically?

So basically lost in BW, right? (As long as even a single visit by children cannot be excluded.)

When it comes to the design, have a glass pane made for it and everything is fine.

Hello,

the clear width for vertical infill bars must be less than 120mm. If, as you requested, horizontal infill bars are to be used, clear widths of max. 20-25mm must be observed. These small distances are intended to prevent a child’s foot from climbing up or slipping through. There is a nice overview of DIN 18065 from TÜV Süd on this, just google it and look for the point "Sicherheit für Kleinkinder". That was the official part.

I have already been able to design the variant you showed, where temporary plexiglass panels were mounted on the inside of the railing as long as the children were still small to prevent climbing. Once the children were old enough, the plexiglass panels were removed again and everything seemed fine. Until someone placed their foot centered on a horizontal infill bar while "talking from above to below" and leaning on the handrail and pressed a bit. The infill bar was already bent... And this with a post spacing of less than 90cm. Flat bars lying horizontally or, even worse, round bars are simply not made for that.

Horizontal clearances of 20-25mm are not only a nightmare from a manufacturing perspective but also a visual disaster.

I do not know the regulations in BW, is the construction there inspected again by the building authority? From the perspective of house building companies, I can well understand that they want to stay out of it. If something happens, it would be their fault. As long as nothing insurance-relevant happens, one could probably turn a blind eye, but nobody willingly takes responsibility for that.
