Quick facts

United States: a blood storage refrigerator has a named entry at 21 CFR 864.9700, described as a device intended for medical purposes that is used to preserve blood and blood products by storing them at cold or freezing temperatures.
United States: the section places it in Class II (special controls) and exempts it from premarket notification subject to the limitations in 864.9.
Canada: Schedule 1 to the Medical Devices Regulations, SOR/98-282 names no refrigerator. Rule 5 reaches "a non-invasive device intended for channelling or storing gases, liquids, tissues or body fluids for the purpose of introduction into the body by means of infusion or other means of administration", and places it in Class II.
Canada: Rule 6, which reaches devices that modify the biological or chemical composition of blood, does not apply, because a storage refrigerator preserves blood rather than altering its composition.
Where two rules could read the appliance differently, section 7 of the Regulations settles it: "If a medical device can be classified into more than one class, the class representing the higher risk applies."
Canadian regulation text used here is current to 2026-09-21 and last amended 2026-06-17, as stated on the official consolidation; the American section was last amended 63 FR 59226, November 3, 1998.

A blood bank refrigerator looks like a laboratory refrigerator with a chart recorder and an alarm. It is bought by facilities and estates teams rather than by clinicians, and it is often treated as plant rather than as a device. In the United States it has a named device section and a special controls position, and in Canada it is reached by a rule about storing body fluids for later administration into the body. Both frameworks agree on the class, and neither of them treats the appliance as ordinary refrigeration.

Does a blood storage refrigerator carry the same class in Canada and the United States?

On the class, yes: Class II on both sides. On the reasoning, no.

The American section is direct. Section 864.9700(a) identifies a blood storage refrigerator and a blood storage freezer as devices intended for medical purposes that are used to preserve blood and blood products by storing them at cold or freezing temperatures. Section 864.9700(b) places them in Class II, special controls, and exempts them from premarket notification subject to 864.9. The special controls line is the part that distinguishes this entry from the Class I sections around it: the Food and Drug Administration has placed the appliance in the class that carries a controls statement, not the class that carries only general controls.

Canada reaches Class II by a storage rule rather than by an equipment rule. The appliance does not enter the body, so the invasive rules do not reach it. Rule 5 then applies to a non-invasive device intended for channelling or storing gases, liquids, tissues or body fluids for the purpose of introduction into the body by means of infusion or other means of administration, and places it in Class II. Blood stored in the appliance is stored so that it can later be transfused, which is administration into the body.

Two neighbouring rules are worth naming because they are the ones a reader jumps to first. Rule 6 reaches a non-invasive device intended for modifying the biological or chemical composition of blood or other body fluids for the purpose of introduction into the body; a refrigerator holds blood at temperature and does not modify its composition, so Rule 6 does not apply. Rule 12, the catch-all for any other active device, would give Class I. Section 7 then applies the higher-risk class where more than one rule could read, and the class settles at Class II.

Item	Canada	United States
Named entry for a blood storage refrigerator	None in Schedule 1	864.9700, blood storage refrigerator and freezer
Route to a class	Rule 5, storage of body fluids for introduction, Class II	864.9700, Class II, special controls
Rule that does not apply	Rule 6, modification of blood composition	No equivalent modification category in the section
Catch-all that would give a lower class	Rule 12, other active device, Class I	Not applicable; the named section governs
Where two rules could read	Section 7, higher-risk class applies	The named section governs
Premarket notification	Not applicable at Class II on these facts	Exempt, subject to the limitations in 864.9

How do the special controls in the United States differ from the storage rule in Canada in practice?

They differ in what each one is designed to control, and that changes what a facility should hold on file.

The American entry names a controls position. Special controls are the measures that, together with general controls, give reasonable assurance of safety and effectiveness for a device in Class II. For a blood storage refrigerator that means the manufacturer carries an obligation that is more specific than the general quality system position, and the facility buying the appliance is buying a device that sits inside that framework.

The Canadian rule says nothing about controls. It fixes the class by reference to what the appliance stores and why. That is why the Canadian file for a blood bank refrigerator should describe the intended use as the storage of blood and blood products for transfusion, rather than describing the appliance as refrigeration equipment. The intended use is the fact that brings Rule 5 into play, and it is the fact that keeps Rule 12 from being read as the only applicable rule.

Question	Canada	United States
What fixes the class	The stored fluid and its later administration	The named entry for the appliance
Is there a controls statement	No; the class is fixed by the rule	Yes; the section names special controls
What the facility should record	The intended use for transfusion	The entry and the controls position
Does the rule depend on a medical promotion	No; the storage purpose decides	The entry describes a device for medical purposes
Class if read as plain refrigeration	Rule 12 would give Class I	Outside the identification paragraph

What does a Canadian facility record for a Class II blood storage refrigerator?

Six records, and the temperature log is the one that carries the most weight.

The device record. The appliance register entry with a unique identifier, mapped to the physical unit and its location in the blood bank.
The intended use. The storage of blood and blood products for transfusion, stated in those terms rather than as general refrigeration.
The temperature log. The continuous or scheduled record of the storage temperature, with the alarm set points and the action taken when a deviation is recorded.
The alarm test record. When the high and low alarms were last tested, and how the test was performed.
The manufacturer's instructions. Maintenance, cleaning and calibration instructions, filed with the appliance rather than with the contract.
The class position. A short note recording why the appliance is treated as Class II, with the rule relied on, so the file does not have to be rebuilt for a new estates contract.

Which consumables does a blood bank restock alongside its storage appliances?

Storage appliances and the consumables that run with them are ordered on the same cycle. For facilities buying at case level, the wholesale ordering page sets out account and case terms, and the B2B wholesale collection lists the lines held for institutional buyers. The sterile centrifuge tubes cover the component separation step, the 24-hour biological indicator incubator covers the incubation step where the same site also runs a steriliser, and the monitoring collection sits with the biological indicator 5-pack trial where a processing area is shared.

A storage appliance is only as good as the log taped to it. The printable weekly storage and cycle log is a free A4 form with a release column that can carry a unit identifier and a temperature field when a single room runs both storage and processing. The generator that lays out one page per week builds the sheet around the number of units and the cycles the site runs, keeping the form to one page per week. No account and no sign-up are needed to open either one.

Where an appliance sits between an equipment rule and a storage rule, the answer that matters is the one written for your own site. Ask a compliance specialist and a written answer comes back specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions

Is a blood storage refrigerator a regulated device in Canada?

Yes. It is a non-invasive device, and Rule 5 of Schedule 1 to the Medical Devices Regulations reaches a device intended for storing body fluids for the purpose of introduction into the body by means of infusion or other means of administration. That places it in Class II.

Why does Rule 6 not apply to a blood storage refrigerator?

Because Rule 6 reaches a device intended for modifying the biological or chemical composition of blood or other body fluids. A storage refrigerator holds blood at temperature and does not alter its composition, so the modifying rule is not the one that governs it.

What is different about the American entry?

Section 864.9700 places the appliance in Class II with special controls and exempts it from premarket notification subject to 864.9. The controls position is stated in the section, which is more specific than the general controls position that a Class I device carries.

What if two Canadian rules could read the appliance differently?

Section 7 of the Medical Devices Regulations answers this. If a medical device can be classified into more than one class, the class representing the higher risk applies.

Does a facility need a temperature log for a Class II storage appliance?

The class does not create the log, but the intended use does. A facility storing blood for transfusion should record the storage temperature, the alarm set points and the action taken when a deviation is recorded, and keep the record with the appliance.
