Development↦Biobanking↦Biobank Set-Up↦Equipment Maintenance
What is it? Why is it important?
Equipment maintenance are reoccurring checks (e.g. usually yearly) to ensure biobanking equipment performs as intended.
Equipment maintenance checks can include:
- Calibration tests for accuracy, such as the ability for:
- Pipets to aspirate an exact amount of liquid
- Centrifuges to rotate and maintain a given preset speed(s)
- Laboratory scales to correctly weigh products to the smallest mg
- Functional tests, such as:
- Freezers able to reach a minimum predefined temperature (e.g. -80°C)
- Alarms able to respond within a given timeline upon being triggered
- Laminar hood blower able to reach maximum expected hair flow
Guaranteeing optimal equipment performance requires that monitoring systems continuously run in the background (e.g. 24hr / 7 days a week). Upon excursions from the norm (e.g. changes in temperature, humidity, CO2 levels) an alarm is triggered notifying a response team. Thus, sensors record and relay information back to a control center (e.g. person or machine), initiating follow-up activities.
What do I need to do?
Based on your equipment:
- Establish a calibration and maintenance plan (e.g. write an Equipment Surveillance (ES) manual, SOP or WI)
- In the plan include manufacturer or technical experts able to provide support in the calibration and maintenance of equipment
- Reappraise and adapt ES schedules to ensure that equipment maintains optimal performance over time
- Label equipment that has undergone maintenance
- Keep an ES log book (e.g. include findings and improvement measures)
- Train staff on ES procedures
Based on risk-assessment, define critical equipment that requires a high level of ES, due to far reaching consequences in the event of equipment failure. Additional activities for critical equipment include:
- Ongoing surveillance systems with access to a response team 24hr / 7 days a week
- The definition of applicable emergency plans (e.g. freezer emergency plan)
- The availability of back-up equipment in the event equipment downtime
The required calibration and maintenance frequency is provided by the equipment manufacturer. Other aspects that should be taken into consideration are:
- The frequency of use
- Defined risks, based on the seriousness of potential consequences due to equipment malfunction or breakdown
