Before use, NFPA 1192 requires potable water tanks to be what?

The correct answer is that potable water tanks must be sanitized, flushed, and drained before use, according to NFPA 1192 standards. This process is essential to ensure that the water system is free of contaminants and safe for human consumption.

Sanitizing the tanks eliminates harmful microorganisms that could potentially cause illness. Flushing the tanks helps to remove any residual cleaning agents or contaminants that may have accumulated. Draining is necessary to clear out any remaining water that may not have been sanitized or flushed properly. This comprehensive approach ensures the health and safety standards for potable water systems are met, thereby protecting users and maintaining the integrity of the water supply.

While inspection, cleaning, testing, and treatment can also be important steps in maintaining potable water tanks, they do not specifically align with the requirements established by NFPA 1192 prior to initial use of the tanks.
