ANSI/AAMI RD52:2004 Requirements as Adopted by Reference 42 CFR 494.40(a)
5.5.3 Acid concentrate distribution systems (labeling)
Acid concentrate delivery piping should be labeled and color-coded red at the point of use
(at the jug filling station or the dialysis machine connection).
All joints should be sealed to prevent leakage of concentrate. If the acid system remains
intact, no rinsing or disinfection is necessary.

More than one type of acid concentrate may be delivered, and each line should clearly
indicate the type of acid concentrate it contains.
Interpretive Guidance § 494.40(a)
ANSI/AAMI RD52:2004
5.5.3 Acid concentrate distribution systems
Acid concentrate is not susceptible to bacteria contamination, but every effort should be made to
keep the system closed to prevent nonbacterial contamination and evaporation.
Additional Guidance:
If more than one acid is centrally delivered to treatment stations, outlets must be clearly labeled
with the acid type.

Unofficial copy of government-published law, reproduced from official sources with full provenance. Not an official publication; verify against official sources before relying on it in a filing. Records in the 'guidance' corpus, and only that corpus, are sub-regulatory (interpretive guidelines, survey procedures) and are not binding law. Validity bounds follow each jurisdiction's declared temporalBasis.
