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.
The height will vary depending on the code. The IBC requires a guard to be 42 in height. Handrails are located between 34 and 38 and have dimensional limitations for graspability. As such, if a 42 guardrail is called for on a stair or ramp, it will also require a secondary handrail at the appropriate height.
