  1. Facilities and Equipment Version 5.0, August 2012

  2. Objectives • List the requirements of laboratory facilities with regard to work space • Describe the importance of appropriate facility maintenance • Describe the importance of maintaining accurate laboratory equipment • Describe methods used to verify accuracy of laboratory equipment • Describe procedure for documenting maintenance, calibration, and corrective actions • Describe optimal maintenance of reagents

  3. Overview Laboratory Facilities Data Storage Facilities Environmental Control Equipment Maintenance Equipment Inventory Reagents Reagents Inventory

  4. Pre-Assessment Question #1 Which of the following are necessary for laboratory facilities to ensure high standards of quality work, data and safety? • Spills should be cleaned when convenient • Provide a safe environment for personnel • Proper lighting should be provided to ensure sufficient visibility • A and B only • B and C only • A and C only

  5. Pre-Assessment Question #2 The following can occur in facilities with inadequate laboratory space: • Frequent laboratory accidents • Increased incidences of specimen loss or mix-ups • Sub-optimal equipment performance • Likelihood of incorrect results being reported • All of the above • A and B only

  6. Pre-Assessment Question #3 Maintaining accurate laboratory equipment is important for: • Generation of accurate results • Minimizing the costs of repair • Reporting results in a timely manner • All of the above

  7. Pre-Assessment Question #4 DAIDS Good Clinical Laboratory Practices (GCLP) requires that pipettes are checked for volumetric accuracy and reproducibility and recalibrated at what defined frequency? • Monthly • Annually • At minimum every 6 months • Every 2 months

  8. Pre-Assessment Question #5 Why is it important for clinical research laboratories to document temperature monitoring and maintenance activities for laboratory equipment, including calibration and quality control (QC) testing? • It is a GCLP requirement • It ensures maintenance of an effective Quality Management systems • It provides evidence of compliance to documented procedures and policies • It assists in easy identification and corrections of problems associated with inadequate performance of these activities • All of the above • A and B only

  9. Pre-Assessment Question #6 Which of the following are required for reagent labeling per GCLP guidelines? • Lot number and expiration date • Open and reconstitution date • Date received from manufacturer • A and B • B and C • A and C

  10. Facilities DAIDS GCLP Guidelines Laboratories should be designed so that safety of employees and quality of work are not compromised.

  11. Laboratory Facilities Access restriction to authorized personnel Availability of break rooms and office areas Data storage areas Evacuation plans Specimen integrity

  12. Fixtures

  13. Safety Signage Should be placed in relevant laboratory areas and be visible First Aid Escape Route Hazardous Corrosive Explosive Fire Extinguisher Flammable Toxic Biohazard Eyewash

  14. Document daily cleaning activities • Clean spills immediately Work Areas • Adequate for proper specimen handling • Provide safe environment for personnel Housekeeping • Ensure sufficient visibility Work Space Lighting • Provide logical flow of work to prevent mix-ups and specimen loss Personnel Traffic • Limit personnel traffic • Maintain unobstructed walkways Segregation of Testing Activities

  15. Facilities Sample integrity Equipment performance Unsuitable facilities affect Personnel safety and competency Compliance conditions set in the test

  16. Data Storage Facilities • Separate areas should be provided for data storage. • Adequate security - unauthorized personnel should not have access to archived data. • Archive should be secure. • Facilities should be flood-proofed, fire-proofed, fire resistant, and protected from rodent infestation.

  17. Environmental Control Humidity Temperature Dust Interferences

  18. Temperature Recording Temperature Control • Temperature monitoring activities should be documented Tolerance Limits • Established by determining the minimum range of values common to the defined tolerance limits for reagents in storage or the recommended incubation temperature for the assays being performed Temperature Review • Monthly review of temperature charts

  19. Temperature Logs

  20. Temperature Logs (cont.)

  21. Skill Check You are required to store in the refrigerator reagent kits with the following manufacturer recommended storage temperature ranges: • 2°C to 8°C • 0°C to 25°C • 3°C to 8°C • 3°C to 10°C • 3°C to 6°C • 3°C to 10°C • ALT: 0°C to 8°C • Pregnancy test: 2°C to 25°C • Rapid HIV: 3°C to 10°C • Chemistry Controls: -10°C to 6°C The optimal refrigerator temperature storage range would be defined as:

  22. Skill Check The refrigerator where reagent test kits are stored malfunctioned over the weekend. The laboratory personnel are not sure what to do with all the refrigerator contents; they worry that if they discard everything, huge losses would be incurred. How would you advise them as the Laboratory Director? • Not to take a chance, but discard all contents • Mark affected materials to indicate possible quality problems • Continue using the reagents and kits as long as the QC is acceptable • Perform parallel testing with new batches • Shorten the expiration dates of the reagents and kits • B and D

  23. Skill Check The following cannot be performed in the laboratory with a defined ambient room temperature range of 16°C to 28°C: • 14°C to 28°C incubation temperature range for the HBsAgMonolisa test • 2°C to 25°C storage temperature range of the FACSCalibur reagents • 2°C to 27°C storage temperature range of the HIV Determine kits • 25± 2°C incubation temperature range for the Vironostica HIV EIA test • B, C and D • A and E

  24. Equipment Optimal working laboratory instrumentation is vital for: • Maintenance of productivity • Generation of accurate results • Lowering the incidents of equipment malfunctions • Minimizing the costs of repairs • Reporting results in a timely manner

  25. Equipment Per DAIDS GCLP Guidelines, the laboratory should maintain documentation to support that equipment is properly: • Validated • Operated • Inspected • Maintained • Tested • Calibrated

  26. Equipment Documentation Scheduled Preventative Maintenance Unscheduled Maintenance Service Calibration

  27. Equipment Management Monitoring of equipment management activities through: Training and evaluation of competency Review of maintenance, service, calibration, and QC records Review of procedures and updating, as required Ensuring compliance with documented procedures

  28. Preventive Maintenance/Calibration Plan • An equipment service schedule should be maintained • The list should include all equipment and the accompanying due dates of service and calibration • Ideally, the equipment list should be displayed
