STAFF TRAINING IS CRITICAL
Provide all vaccination staff with proper training in cold chain supply, freezer operations and frozen sample handling.
ULT FREEZER SELECTION MUST MEET LOCAL REQUIREMENTS
- Choose freezers with the widest temperature range to accommodate vaccine candidates and choose the smallest freezer required.
- Confirm the power configuration available in your lab prior to purchase, especially in areas with low-grade power supply.
- Have a dedicated backup power system in place in case of power outage.
- Install an independent internal thermometer sensor to log/alert against temperature fluctuations. Ensure internet or Wi-Fi access and send alerts to multiple staff.
ULT FREEZER INSTALLATION REQUIRES A SPECIFIC STORAGE AREA
- Each freezer requires an independent circuit. Ensure outlets are on an emergency circuit with built-in redundancy.
- Ensure room where freezer will be housed can handle additional heat load. ULT units will increase humidity and temperature.
- ULT freezers need to pull air in and exhaust without restriction.
Check clearance requirements outlined by each manufacturer before purchase.
ULT FREEZER OPERATION AND MAINTENANCE MUST BE COORDINATED
- Access to vaccines needs a strict procedure for how staff will manage door openings. Aim for few and short door openings to avoid freezer temperature fluctuations. Allow the freezer to return to set temperature.
- Avoid an empty unit. If you do not have product to fill the unit, consider adding empty aluminum racks to fill it.
- Regularly clean the condenser and gaskets to prevent ice formation, especially around doors.
- Ensure ULT freezers are calibrated for accuracy of temperature display.
ULT FREEZER EMERGENCY PLANNING
- Draft an emergency plan in case of freezer failure, power outage, natural disaster, and other common hazards.
- Have a written procedure for transferring specimens to alternative storage (e.g. dry ice).
