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.
Handrails must be at a height that the average person can grab readily as they go up or down steps. Some jurisdictions require railings to be 31 inches to 36 inches above the nosings of the steps. In other jurisdictions, they have to be 34 inches to 38 inches above nosings. Check your area requirements.
