Page 2 of cover.SAFETY PRECAUTIONS are superseded as follows:
It is mandatory that the safety precautions prescribed in FM 10-20 be followed whenever a bolted steel tank is being
disassembled, repaired, or reassembled.
If a tank has been used for petroleum products, it must not be used for potable water.
If a tank is to be used for potable water storage, do not apply sealing compound or sealing putty to the tank sides or
Scaffold boards must be tested on the ground, prior to being installed in the scaffold, to be sure they are sound and free
from defects. Nail overlap of scaffold board together. Install a guard rail on all scaffolding. Securely tie rope safety
railing to each post. Individually, they are not resistant to lateral bending; but tied together, they form a strong resistance
to lateral and outward bending .Adiagonal line from the top of every 4th or 5th post to the bottom of the adjacent post is
also recommended .Do not install guard wire supports over stave chine-lap seams or deck lap seams.
