Compliance overview
Scope and applicability
This standard specifies the basic requirements for facilities, equipment, and safety management of mobile laboratories at biosafety levels 1, 2, and 3. It applies to mobile labs involved in biological factor operations, including both self-propelled and carrier-based models. This standard does not cover mobile BSL-4 laboratories or open/semi-open animal housing BSL-3 laboratories. It is essential for manufacturers and operators of mobile biological testing units entering the Chinese market.
Technical requirements
The standard outlines comprehensive design principles and basic requirements for mobile laboratories, emphasizing modularity, integration, and standardization to ensure general applicability and ease of maintenance. Manufacturers must ensure that all facilities and equipment are reliably fixed and capable of withstanding vibration and shock during transit. The requirements cover environmental adaptability, including resistance to temperature, humidity, wind, and dust, ensuring the lab's reliability in various field conditions. For BSL-1 and BSL-2 laboratories, the standard specifies requirements for primary and secondary barriers, ventilation systems, and basic laboratory layouts. BSL-2 labs may require negative pressure ventilation systems with directional airflow principles and interlocking doors at buffer entrances. Proper disinfection and sterilization devices must be equipped based on the risk assessment. For higher-risk BSL-3 and ABSL-3 laboratories, the standard mandates strict zoning between auxiliary work areas and containment areas. It specifies requirements for pressure differentials, HEPA filtration for supply and exhaust air, and independent power supply systems with redundancy. GB 19489-2008 is referenced for general laboratory biosafety requirements, while GB 14925-2010 is cited for laboratory animal environments. Management requirements dictate that a comprehensive risk assessment must be conducted before, during, and after the movement of the laboratory. Organizations must establish detailed action plans, field work procedures, and emergency response protocols. This includes designating qualified personnel, conducting pre-movement safety inspections, and ensuring all waste is properly decontaminated before transport.
Testing methods
The standard references several testing methods to verify the safety performance of mobile labs, particularly for BSL-3 facilities. Key evaluations include visual inspection of the lab's exterior and functional components, containment structure tightness testing using smoke detection methods, and HEPA filter in-situ leak testing using particle counters. Additionally, it requires testing of room static pressure differentials and pressure gradients to ensure directional airflow is maintained under normal operating conditions.
FAQs
What products are regulated under GB 27421-2015?
GB 27421-2015 regulates mobile laboratories operating at biosafety levels 1, 2, and 3, including both self-propelled and transportable units used for handling biological factors.
Does GB 27421-2015 apply to mobile BSL-4 laboratories?
No, the standard explicitly excludes requirements for mobile biosafety level 4 laboratories and open or semi-open animal housing biosafety level 3 laboratories.
How does GB 27421-2015 relate to other Chinese standards?
It is based on GB 19489-2008 (General requirements for laboratory biosafety) and adapts those requirements specifically for the unique characteristics of mobile laboratories, also referencing GB 14925-2010 for animal laboratory environments.
