I would like to ask everyone for advice regarding the maintenance of the tanks at the sewage treatment plant

What type of ladder do people use for pool maintenance? The pools are 7 or 8 meters deep.
A hanging ladder is sufficient; if there is enough funding for safety measures, a walkable ladder can be installed, which is suitable for operations in factories where multiple people and different types of work are carried out
Analysis must show compliance before personnel can be sent down; proper supervision is required! ! ! ! ! ! ! ! ! !
Yes, are you using a soft ladder or an extendable ladder?
rope ladder； Hanging shave ； Either one is fine ； Conditionally weldable straight ladder ； Those with a protective cage are better
The welded ladder was not made, as it is located in an anaerobic tank and staying submerged in water for long periods is unsafe
It doesn’t matter whether it’s a soft ladder or an extendable ladder; what’s important is to ensure safety and efficiency! ! ! ! ! ! ! The maintenance ladder can be designed according to local conditions; it is recommended to include this in the maintenance plan! ! ! ! ! ! ! ! ! !
The welded ladder can be made of stainless steel； Even those made of steel ； Doing a good job at corrosion prevention is also possible
There must also be security risks, thanks for your reply
