3. Safety

READ BEFORE OPERATING THIS EQUIPMENT General Liquid nitrogen (LN2) is used in MVE Cryogenic Freezers as a refrigerant. Understanding and following certain safety precautions is extremely important when handling LN2 and cryogenic containers (Dewars). Liquid Nitrogen Properties Nitrogen is a colorless, odorless, tasteless gas. Gaseous nitrogen makes up about 78% of the Earth’s atmosphere by volume. Once collected and isolated, nitrogen can be liquefied. Boiling Point @ 1 atm Thermal Conductivity (Gas) Heat of Vaporization (Liquid) Density @ 1 atm (Liquid)

-195.8°C , -320.3°F , 77.4 K 25.83 mW/(mÂK) 198.38 kJ/kg 3 1.782 lbs/L , 807.4 g/L , 808.6 kg/m

Liquid Nitrogen Safety Transferring LN2 and operating the TEC 3000 should be done in accordance with the manufacturer/supplier instructions. It is important that all safety precautions written on the storage Dewar and recommended by the manufacturer be followed.

WARNING • •

•

•

Do not modify this equipment without authorization of the manufacturer. Nitrogen is a potential asphyxiant and can cause rapid suffocation without warning. Store and use in area with adequate ventilation. DO NOT vent container in confined spaces. DO NOT enter confined spaces where gas may be present unless area has been well ventilated. If inhaled, move to fresh air. If breathing is difficult, supplemental oxygen may be required. If not breathing, give artificial respiration. SEEK MEDICAL ATTENTION IMMEDIATELY! Liquid nitrogen can cause severe frostbite to the eyes or skin. DO NOT touch frosted pipes or valves. Cold nitrogen vapor can damage the eyes or skin. In case of frostbite, consult a physician at once. If a physician is not readily available, warm the affected area with water that is near body temperature. Never place LN2 in a sealed container without a pressure relief device. The expansion ratio of liquid nitrogen to gaseous nitrogen is approximately 1 to 700 (i.e. 1 cubic foot of LN2 becomes 700 cubic feet of gas when evaporated)

The two most important safety aspects to consider when handling LN2 are adequate ventilation and eye and skin protection. Although nitrogen gas is non-toxic, it is dangerous in that the gas will displace oxygen in a normal breathing atmosphere. Liquid products are of even greater threat since a small amount of liquid evaporates into a large amount of gas. Therefore, it is imperative that cryogenic supply and storage Dewars be stored and operated in well-ventilated areas. Persons transferring LN2 should make every effort to protect the eyes and skin from accidental contact with liquid or cold vapor. Chart MVE recommends the following protective clothing and accessories when transferring LN2 or handling hoses, valves, and plumbing components: 13289499 Rev E • 6

 MVE Biological Systems

TEC 3000 Technical Freezer Manual

Recommended protective clothing • Cryogenic gloves (loose fitting) • Full-face shield or chemical splash goggles • Cryogenic apron • Long sleeve shirt and cuff less pants • Closed toe shoes (no sandals) Equipment Usage Cryogenic containers must be operated in accordance with the manufacturer/supplier instructions. Safety instructions will also be posted on the side of each Dewar. Cryogenic Dewars must be kept in a wellventilated area protected from weather and away from heat sources. In applications that use a modular liquid cylinder as a source of LN2, the supply will need to be replenished at regular intervals to ensure proper operation of the freezer. When exchanging liquid cylinders, follow the below procedure: 1. Allow all plumbing components to warm to room temperature before attempting to change supplies. 2. Close all valves associated with the liquid supply cylinder. 3. Relieve pressure in the plumbing assembly by initiating a brief fill by either pressing “Start Fill” or using the manual fill button. 4. Loosen the plumbing connection for the transfer hose at the liquid cylinder. 5. Remove empty liquid cylinder and replace with full liquid cylinder pressurized to 22 - 35 psig (1.52 - 2.41 bar). 6. Attach the transfer hose to the plumbing connection on the liquid cylinder. Ensure that the hose is connected to the connection labeled “LIQUID”. 7. Tighten the transfer hose plumbing connection at the liquid cylinder. 8. Open the liquid supply valve on the liquid cylinder. 9. Inspect plumbing for audible and visual leaks. Repair if necessary. 10. Manually initiate a fill to verify proper operation.

Recommended First Aid Every site that stores and uses LN2 should have an appropriate Material Safety Data Sheet (MSDS) present. The MSDS may be obtained from the manufacturer/distributor. The MSDS will specify the symptoms of overexposure and first aid to be used. Here is a typical summary. If symptoms of asphyxia such as headache, drowsiness, dizziness, excitation, excess salivation, vomiting, or unconsciousness are observed, remove to fresh air. If breathing has stopped, give artificial respiration. CALL A PHSYICIAN IMMEDIATELY. If breathing is difficult, supplemental oxygen maybe required. If exposure to cryogenic liquids or cold vapor occurs, restore tissue to normal, body temperature (37°C) as rapidly as possible, and then protect the injured tissue from further damage and infection. Rapid warming of the affected areas is best achieved by bathing it in warm water. The temperature of the water used should not exceed 40°C. Under no circumstances should the frozen part be rubbed either before or after warming. If the eyes are involved, flush them thoroughly with warm water for at least 15 minutes. In case of massive exposure, remove clothing while showering with warm water. The patient should not drink alcohol or smoke. CALL A PHYSICIAN IMMEDIATELY.

4. Certifications and Listings All fully automatic Chart MVE cryogenic freezer systems equipped with TEC 3000 controllers are UL / CUL listed and CE marked to the Low Voltage Directive (LVD). Specially designated freezer models are also CE marked to the Medical Device Directive (MDD). The LVD is a European Union directive regulating the construction and operation of electrical equipment that is not considered a medical device. The MDD is a European Union directive regulating medical device construction and operation. These listings and certifications encompass the entire freezer system, and not just the electronic controller.

M.D.D. Representative: Medical Product Services Borngasse 20 35619 Braunfels, Germany Chart MVE brand manufactured liquid nitrogen freezers covered in this manual are non-hazardous, open mouth vacuum insulated dewars. They are constructed of stainless steel and aluminum and specifically designed to hold liquid nitrogen. They are not subject to any pressure vessel codes as they are open to atmospheric pressure. MVE liquid nitrogen containers are shipped empty without liquid nitrogen or any hazardous material from our factory. An MSDS is not available for the final formed and welded assembly. An MSDS on the stainless steel or aluminum alloys used is available but is not specific for the complete manufactured vessel.

This freezer is designed for easier access to the plumbing stack. This also allows for lower height clearance. The HEco is available only in the automatic fill version. Model description example MVE HECO 1536P-190AF-GB

CAUTION: Pinch hazard, use caution when opening and closing the plumbing and electrical enclosures.

5.2 Plumbing Assembly The plumbing assembly carries and regulates the flow of LN2 from the liquid supply through the annular fill line, and into the freezer. There are three plumbing assembly configurations; one for the HE/Stock Series, one for the HEco Series, and one for the MVE/Cabinet Series. Each one of these configurations are comprised of three main circuits: fill circuit, purge circuit, and optional gas bypass circuit. HE Series / CryoSystem 6000 Plumbing Assembly
