5.4.4.3 Bicarbonate concentrate mixing systems

Once mixed, bicarbonate concentrate should be used within the time specified by the

manufacturer of the concentrate.

7 Strategies for bacterial control

7.1 General

Storage times for bicarbonate concentrate should be minimized, as well as the mixing of

fresh bicarbonate concentrate with unused portions of concentrate from a previous batch.

The manufacturer’s instructions should be followed if they are available.

Interpretive Guidance § 494.40(a)

Bicarbonate concentrates should be used or discarded within the manufacturer’s timelines, if

these are available. If bicarbonate concentrates are mixed, the maximum allowable time of the

older concentrate would supersede that of the fresh concentrate, after which the batch would

either need to be used or discarded. If facility staff members combine bicarbonate concentrate

from partially used jugs, there should be some system to ensure the concentrate is not kept past

the maximum storage time of the oldest portion. Facilities that allow carryover of unused

concentrate, e.g. unused mixed bicarbonate concentrates are stored for more than one day,

should ensure that the leftover concentrate does not remain past the time specified by the

manufacturer.

Central delivery systems should be cleared of bicarbonate solution at some point during the

treatment day and rinsed clear. Generally this is done at the end of the treatment day.
