All maintenance operations must be carried out by trained personnel.
The design and the materials used for manufacturing the tank reduce
maintenance to simple periodical cleaning.
The personnel must be equipped with the individual safety devices
commonly used for similar operations, and must follow the safety
procedures described in the following paragraph.
