Following the introduction of the revised BS EN 12469-5:2025 standard, multiple NHS healthcare facilities required specialist servicing, testing and compliance support for their microbiological safety cabinets (MSCs) and associated laboratory containment equipment.
Operating across live clinical and laboratory environments, the Trust required an experienced engineering partner capable of delivering compliant maintenance, performance verification and remedial works with minimal disruption to essential healthcare services.
The Challenge
The introduction of BS EN 12469-5:2025 – Biological Safety Cabinets: Installation, Commissioning and Routine Testing introduced updated testing and maintenance requirements for microbiological safety cabinets and containment equipment.
The NHS required a structured, multi-site programme that would:
- Ensure compliance with the latest BS EN 12469-5:2025 standard
- Coordinate servicing across multiple operational healthcare facilities
- Complete planned preventative maintenance and remedial repairs
- Verify containment performance using recognised testing methods
- Minimise disruption within critical clinical and laboratory environments
The project included the servicing and testing of:
- Microbiological Safety Cabinets (MSCs)
- Fume cupboards
- Downdraught benches
- Storage cabinets
- Macerators
Maintaining containment integrity, equipment reliability and regulatory compliance across multiple sites required careful planning and specialist expertise.
Our Solution
Impact Technical Services delivered a comprehensive multi-site laboratory servicing and compliance programme, tailored to the operational requirements of each NHS facility.
Our technicians carried out:
- Planned preventative maintenance
- Functional servicing and inspections
- HEPA filter replacement programmes
- Remedial repairs
- Performance verification testing
- Compliance reporting and certification
To verify containment performance, we completed specialist testing using calibrated equipment, including:
- DOP HEPA filter integrity testing
- KI-Discus airflow and containment testing
All servicing and testing was completed by fully trained engineers using recognised testing methodologies and calibrated instrumentation, ensuring each cabinet continued to provide safe operator protection, product protection and environmental containment.
The Result
The project enabled the NHS Trust to:
- Achieve compliance with BS EN 12469-5:2025
- Verify the performance and containment integrity of critical laboratory equipment
- Restore equipment performance following filter replacements and remedial works
- Maintain safe clinical and laboratory environments
- Receive comprehensive compliance documentation and testing records
- Reduce operational risk across multiple healthcare facilities
By delivering a coordinated, multi-site programme with minimal disruption, Impact Technical Services demonstrated its expertise in supporting NHS laboratories, healthcare facilities and regulated environments with specialist microbiological safety cabinet servicing, DOP testing, KI-Discus testing and laboratory compliance services.
