How tall should the water tank be, with a guardrail on top?
Thread Content
Make a water tank at atmospheric pressure with a diameter of 2 meters and a height of 2.2 meters. There are a water replenishment valve and a manhole at the top. I would like to ask whether it is necessary to install guardrails on the top of the water tank, what standards apply in this regard, and how tall they should be before guardrails are installed
Whether the water tank is used on the ground or mounted at a high height, there is no need to install guardrails on it – it’s pointless
If it exceeds 2 meters, guardrails are required, with a height of 1.2 meters.
Railings should be installed where the height difference exceeds 1.2 meters
Is there a regulation or standard requiring guardrails for structures over 2 meters high?
Refer to standard GB 4053.3-2009 Safety requirements for fixed steel ladders and platforms – Part 3: Industrial protective railings and steel platforms
If it is used for operations frequently, it is still necessary to set it up.
