BERLIN-A herd of dairy cows nearly lifted the roof off their barn in central Germany when methane released by the animals caused an explosion. Police in Hesse state said in a statement that a static electric charge apparently triggered the detonation, and a spurt of flame, on Monday at a farm in Rasdorf. The roof was slightly damaged and one cow suffered light burns.
Handrails shall be provided on at least one side of each continuous run of treads or flight with four or mâ¦ore risers. - Maximum riser height allowed by code is 7 3/4 and you would need to have 3 or less risers to omit a handrail. The answer would be 23 1/4 max.
Most stairways require a banister. Stair banisters, or handrails, are required by code on all steps with more than four risers. They also require that returns are placed on both ends. Returns are 90-degree elbows on the ends that butt into the wall to prevent things from catching on the ends of the banister.
