Biosafety vs Biosecurity: Key Differences and Complementary Roles in Laboratory Management

Biosafety and biosecurity are two distinct but interconnected frameworks that protect laboratory workers, the surrounding community, and the broader environment from biological risks. Biosafety focuses on preventing accidental exposure to or release of biological agents, while biosecurity focuses on preventing intentional misuse, theft, or diversion of dangerous biological materials. Both are essential components of a functional laboratory safety program, and neither can substitute for the other. For laboratory students, technicians, researchers, and diagnostic professionals, understanding the boundary between these two disciplines and how they reinforce each other is a practical requirement for safe and responsible laboratory operation.

Defining Biosafety and Biosecurity in Laboratory Practice

Biosafety in the laboratory context refers to the containment principles, technologies, and practices that protect personnel and the environment from accidental exposure to or release of infectious agents and other biological materials. The World Health Organization's Laboratory Biosafety Manual provides internationally recognized guidance on risk assessment, containment levels, and safe laboratory practices. The scope of biosafety extends beyond genetically modified organisms to include human, animal, and plant pathogens, nucleic acids, proteins, human samples, and by-products of biological work. The common denominator across these materials is the focus on protecting people and the environment through risk assessment and risk management.

Biosecurity, in contrast, addresses the protection of biological materials from unauthorized access, loss, theft, misuse, diversion, or intentional release. While biosafety asks what could happen accidentally, biosecurity asks who could deliberately cause harm and how materials could be misused. Biosecurity measures include physical security of laboratories and storage areas, inventory control and accountability for biological materials, personnel reliability assessments, and protocols for transfer and transport of dangerous pathogens.

The distinction matters in daily laboratory operations. A biosafety failure might involve a spill that exposes a technician to a pathogen. A biosecurity failure might involve a vial of that same pathogen going missing from inventory or being removed by someone without authorization. Both events are serious, but they require different preventive measures and different responses.

The Complementary Relationship Between Biosafety and Biosecurity

Biosafety and biosecurity are not competing priorities but complementary layers of protection. A laboratory can have excellent biosafety practices and still be vulnerable to biosecurity threats. Conversely, strong physical security does not protect workers from accidental exposure if biosafety practices are weak. The World Health Organization's Laboratory Quality Management System Handbook addresses both domains as components of a comprehensive quality system, recognizing that safe and secure laboratory operations depend on integrated management of biological risks.

The overlap between the two disciplines is substantial. Containment equipment such as biological safety cabinets serves both purposes by preventing accidental release and limiting access to hazardous materials. Personal protective equipment protects the worker from exposure and also reduces the chance that a worker could inadvertently carry materials out of the laboratory. Waste decontamination procedures prevent accidental infection and also ensure that dangerous materials cannot be recovered from waste streams.

International frameworks recognize this interconnection. The World Health Organization's revised International Health Regulations, the Biological Weapons Convention, and United Nations Security Council Resolution 1540 all impose requirements that touch on both biosafety and biosecurity. These instruments share the common thread of preventing both accidental release and deliberate misuse of biological agents. For laboratories operating under any of these frameworks, compliance requires attention to both domains.

At a Glance: Biosafety versus Biosecurity

Core Principles of Laboratory Biosafety

Risk Assessment as the Foundation

Risk assessment is the starting point for all biosafety decisions. The World Health Organization's Laboratory Biosafety Manual emphasizes that risk assessment should consider the characteristics of the biological agent, the procedures being performed, the equipment available, and the competence of laboratory personnel. For emerging pathogens with limited available information, risk assessment becomes even more critical because standard assumptions may not apply.

The ISO 35001:2019 biorisk management standard provides a systematic framework for identifying, assessing, controlling, and monitoring risks associated with hazardous biological materials. This standard applies to laboratories and related organizations and helps institutions move beyond ad hoc safety practices toward a structured management system. Laboratories processing samples from patients with unknown infections, testing vaccine candidates, propagating viruses, or validating diagnostic assays all benefit from implementing such systematic approaches.

Containment Levels and Engineering Controls

Containment is the physical manifestation of biosafety principles. Laboratories are typically classified into biosafety levels based on the risk group of the agents handled and the procedures performed. Higher containment levels require additional engineering controls, such as directional airflow, HEPA filtration, and sealed laboratory construction.

Biological safety cabinets are the primary engineering control for most microbiological work. These devices protect the worker, the product, and the environment through directional airflow and HEPA filtration. Proper selection, certification, and use of biological safety cabinets are essential for safe handling of infectious materials. A cabinet that is not certified or is used improperly provides a false sense of security.

Safe Work Practices and Personal Protective Equipment

Engineering controls must be supplemented by administrative controls and personal protective equipment. Safe work practices include hand hygiene, no eating or drinking in the laboratory, proper sharps handling, and careful technique to minimize aerosol generation. Personal protective equipment such as gloves, laboratory coats, eye protection, and respirators provides a final barrier between the worker and hazardous materials.

The effectiveness of these measures depends on consistent application. A technician who follows safe practices only when being observed is a risk to themselves and others. Laboratories need to build a culture where safe behavior is the default, not the exception.

Decontamination and Waste Management

Decontamination is the process of rendering biological materials safe through physical or chemical means. Autoclaving, chemical disinfection, and incineration are common methods. Waste management protocols must ensure that contaminated materials are properly contained, decontaminated, and disposed of according to applicable regulations.

The biosafety implications of waste treatment extend beyond the laboratory. For example, anaerobic digestion of rendered animal carcasses has been evaluated as a potential biocontainment advantage over traditional carcass disposal methods, based on reduced prevalence of antimicrobial resistance genes and virulence-associated factors. This illustrates how biosafety considerations apply across the entire lifecycle of biological materials, from collection to final disposal.

Core Principles of Laboratory Biosecurity

Inventory Control and Material Accountability

Biosecurity begins with knowing what biological materials are present in the laboratory and where they are located. A complete inventory should include the agent, quantity, location, storage conditions, and responsible personnel. Inventory records must be maintained accurately and reviewed regularly to detect discrepancies.

The challenge of inventory control increases with the number of materials and the complexity of the laboratory. Facilities that maintain large collections of pathogens, clinical samples, or genetically modified organisms need robust systems for tracking materials from receipt through use to disposal. Without such systems, materials can be lost, stolen, or diverted without detection.

Physical Security and Access Control

Physical security measures protect biological materials from unauthorized access. These measures include locked storage areas, restricted access to laboratory spaces, visitor controls, and intrusion detection systems. The level of physical security should be proportional to the risk associated with the materials being protected.

Access control is also about locks and keys. It also involves policies about who is authorized to enter laboratory areas, under what circumstances, and with what oversight. Laboratories handling high-risk pathogens need to consider whether access should be limited to specific trained personnel and whether visitors require escorts.

Personnel Reliability and Training

Biosecurity depends on the people who work in the laboratory. Personnel reliability programs help ensure that individuals with access to dangerous biological materials are trustworthy and appropriately trained. These programs may include background checks, security awareness training, and procedures for reporting concerns about colleagues.

Training for biosecurity should be distinct from training for biosafety. Workers need to understand also how to handle materials safely but also how to recognize and report security concerns, such as unusual requests for information, attempts to remove materials, or suspicious behavior by visitors or colleagues.

Secure Transport and Transfer

The movement of biological materials between laboratories, facilities, or countries presents significant biosecurity risks. Materials in transit are vulnerable to theft, loss, or diversion. Secure transport requires appropriate packaging, labeling, chain of custody documentation, and use of trained and vetted couriers.

A study in Mali highlighted the challenges of specimen transport in resource-limited settings. The study compared the use of trained postal services with the existing ad hoc system that relied on untrained public transport companies for shipping suspected meningitis, measles, yellow fever, and polio samples from districts to the central laboratory in Bamako. Only 46% of samples sent by public transportation were received within 72 hours of collection, compared to 71% shipped via the postal service. Additionally, 93% of samples shipped by public transportation arrived in good condition, compared to 98% by postal service. While the postal service was faster and preserved specimen quality, the average cost per specimen was eight times higher. This study demonstrates that secure and reliable transport systems require investment and that cost considerations must be balanced against the risks of spoilage, accidental release, and delays.

Practical Implementation of an Integrated Biorisk Management Program

Step 1: Conduct a Comprehensive Risk Assessment

Begin by identifying all biological materials in the laboratory and assessing the risks associated with each. Consider the pathogenicity of the agent, the routes of transmission, the procedures performed, the volume of material handled, and the potential consequences of accidental exposure or intentional misuse. Document the risk assessment and review it regularly, especially when new agents or procedures are introduced.

The ISO 35001:2019 standard provides a structured approach to this process. It emphasizes that risk assessment is not a one-time event but an ongoing activity that must be integrated into laboratory operations. For emerging pathogens with limited information, risk assessments must be updated as new data become available.

Step 2: Implement Engineering Controls

Install and maintain the engineering controls required for the biosafety level of the laboratory. This includes biological safety cabinets, autoclaves, eyewash stations, and hand-washing facilities. Ensure that equipment is certified and tested according to manufacturer specifications and applicable standards.

For biosecurity, engineering controls include locks, access control systems, security cameras, and inventory tracking systems. The level of physical security should be based on the risk assessment and the value of the materials being protected.

Step 3: Develop and Enforce Standard Operating Procedures

Write clear standard operating procedures for all laboratory activities, including handling of infectious materials, decontamination, waste disposal, and emergency response. Procedures should be specific enough that a new technician can follow them without ambiguity. Train all personnel on these procedures and document their training.

Standard operating procedures should also address biosecurity concerns, such as inventory management, material transfer authorization, and reporting of security incidents. Procedures that are not enforced provide no protection.

Step 4: Establish Training and Competency Programs

Training is a critical control for both biosafety and biosecurity. All personnel should receive initial training before working with biological materials and refresher training at regular intervals. Training should cover the principles of biosafety and biosecurity, the specific hazards of the materials handled, the proper use of equipment, and emergency procedures.

Competency assessment goes beyond attendance at training sessions. Workers should demonstrate that they can perform procedures correctly and safely before being allowed to work independently. The shift from knowledge-oriented training to competency-based professional development has been identified as important in veterinary antimicrobial stewardship, where knowledge of antimicrobial resistance does not consistently translate into responsible antimicrobial use. The same principle applies to laboratory safety: knowing what to do is not the same as doing it correctly under real working conditions.

Step 5: Maintain Records and Documentation

Documentation is essential for demonstrating compliance and for identifying problems. Maintain records of risk assessments, training, equipment certification, incident reports, inventory, and material transfers. Review these records regularly to identify trends and areas for improvement.

The World Health Organization's Laboratory Quality Management System Handbook emphasizes the importance of documentation as a component of laboratory quality. Records serve also as evidence of compliance but also as a tool for continuous improvement.

Step 6: Monitor and Audit Performance

Regular monitoring and auditing help ensure that biosafety and biosecurity measures are working as intended. Monitoring may include visual inspections, environmental sampling, and review of incident reports. Audits should be conducted by individuals who are independent of the activities being audited.

High-reliability organizations, such as those in the aerospace industry, focus on five core principles: preoccupation with failure, reluctance to simplify, sensitivity to operations, resilience, and deference to expertise. These principles are relevant to laboratory biorisk management. A preoccupation with failure means actively looking for what could go wrong instead of assuming that existing controls are sufficient. Sensitivity to operations means paying attention to the details of daily work. Resilience means being able to respond effectively when things do go wrong.

Common Failure Patterns in Biosafety and Biosecurity

Failure Pattern 1: Treating Biosafety and Biosecurity as Separate Programs

Some laboratories have strong biosafety programs but weak biosecurity, or vice versa. This creates vulnerabilities that can be exploited. A laboratory with excellent containment but poor inventory control may not notice when materials go missing. A laboratory with strong physical security but weak biosafety practices may experience accidental exposures that could have been prevented.

The solution is to integrate biosafety and biosecurity into a single biorisk management program. This requires leadership commitment, clear assignment of responsibilities, and regular communication between safety personnel, security personnel, and laboratory staff.

Failure Pattern 2: Documentation That Does Not Reflect Reality

Laboratories sometimes maintain records that look good on paper but do not reflect actual practices. Inventory records may be outdated, training records may show attendance at sessions that did not occur, and risk assessments may be copied from other laboratories without adaptation to local conditions.

This gap between policy and practice has been identified as a significant challenge in synthetic nucleic acid oversight. Policies that look thorough on paper may deliver little added protection if institutions lack the capacity to implement them. The same dynamic applies to laboratory biosafety and biosecurity. Documentation is only valuable if it accurately reflects what is actually happening.

Failure Pattern 3: Inadequate Training and Competency Assessment

Training that consists of a lecture and a signed form does not ensure that workers can perform procedures safely. Workers need hands-on practice, supervision, and assessment of their competence. This is particularly important for complex procedures such as handling highly pathogenic agents or operating sophisticated equipment.

The knowledge-practice gap observed in veterinary antimicrobial stewardship illustrates this problem. Professionals may know about antimicrobial resistance but still fail to use antimicrobials responsibly in practice. Similarly, laboratory workers may know about biosafety principles but still take shortcuts when they are under pressure or when they have become complacent.

Failure Pattern 4: Poor Specimen Transport and Chain of Custody

The transport of biological materials is a common point of failure for both biosafety and biosecurity. Samples that are improperly packaged can leak or break, exposing transport workers and the public. Samples that lack proper chain of custody documentation can be lost, stolen, or diverted without detection.

The Mali pilot study demonstrated that ad hoc transport systems relying on untrained public transport companies carry risks of spoilage, accidental release of pathogens, and delays. Laboratories need to establish reliable transport systems with trained personnel, proper packaging, and documented chain of custody.

Failure Pattern 5: Inadequate Emergency Preparedness

Laboratories that have not planned for emergencies are more likely to experience serious consequences when emergencies occur. Emergency plans should address accidental spills, exposures, fires, security breaches, and natural disasters. Plans should be tested through drills and exercises, and lessons learned should be incorporated into revised plans.

The COVID-19 pandemic highlighted the importance of emergency preparedness for laboratories. Laboratories processing samples from patients with unknown infections needed to rapidly implement new procedures and adapt to changing information about the virus. Those with robust biorisk management systems were better positioned to respond effectively.

Observations and Measurements for Biorisk Management

Incident and Near-Miss Reporting

Tracking incidents and near misses is essential for identifying weaknesses in biosafety and biosecurity programs. An incident is an event that causes or has the potential to cause harm. A near miss is an event that could have caused harm but did not. Both should be reported, investigated, and used to improve practices.

High-reliability organizations emphasize the importance of near-miss reporting. A preoccupation with failure means paying attention to small problems before they become large ones. Laboratories should create a culture where workers feel comfortable reporting near misses without fear of punishment.

Environmental Monitoring

Environmental monitoring can detect contamination that might indicate a failure of containment or decontamination procedures. Surface sampling, air sampling, and biological indicators can be used to verify that decontamination is effective and that containment equipment is functioning properly.

Monitoring results should be documented and reviewed. Trends in environmental monitoring data can reveal problems that might not be apparent from individual samples.

Inventory Audits

Regular inventory audits are a key biosecurity measure. Audits should verify that the materials listed in inventory records are actually present and that no unauthorized materials have been introduced. Discrepancies should be investigated immediately.

The frequency of inventory audits should be based on the risk associated with the materials. High-risk materials may require daily or weekly checks, while lower-risk materials may be audited monthly or quarterly.

Training Effectiveness Assessment

Training effectiveness should be assessed through observation of work practices, written examinations, and practical demonstrations. Workers who cannot demonstrate competence should receive additional training and supervision until they can perform procedures correctly.

Competency-based assessment is more reliable than attendance-based assessment. A worker who has attended a training session but cannot perform the procedure correctly has not been adequately trained.

Quality Controls and Their Relationship to Biosafety and Biosecurity

Quality Management Systems

Quality management systems provide a framework for ensuring that laboratory results are reliable and that laboratory operations are safe and secure. The World Health Organization's Laboratory Quality Management System Handbook addresses the full range of laboratory quality activities, including document control, records management, equipment maintenance, and personnel training.

Quality management and biorisk management are closely related. Many of the same systems that ensure accurate test results also ensure safe and secure handling of biological materials. For example, a system that tracks reagents and samples through the testing process also provides inventory control that supports biosecurity.

Validation and Verification

Validation and verification of laboratory methods are essential for ensuring that tests produce reliable results. The U.S. Food and Drug Administration's Bioanalytical Method Validation Guidance provides recommendations for validating analytical methods used in clinical studies. The National Center for Advancing Translational Sciences' Assay Guidance Manual provides similar guidance for assay development and validation.

Validation is relevant to biosafety because it ensures that procedures are performed correctly and that results are interpretable. A test that has not been validated may produce false results, leading to incorrect clinical decisions or failure to detect a dangerous pathogen.

Proficiency Testing

Proficiency testing involves sending samples to a laboratory for analysis and comparing the results with expected values. This external quality assessment helps laboratories identify problems with their testing procedures and take corrective action.

Proficiency testing also has implications for biosafety and biosecurity. Laboratories that participate in proficiency testing must handle samples that may contain infectious agents, requiring appropriate containment and security measures.

Regulatory and International Frameworks

World Health Organization Guidance

The World Health Organization's Laboratory Biosafety Manual and Laboratory Quality Management System Handbook provide internationally recognized guidance for laboratory safety and quality. These documents are updated periodically to reflect advances in knowledge and technology.

The WHO guidance emphasizes that biosafety and biosecurity are essential components of laboratory management. Laboratories should implement both in a coordinated manner, recognizing that they address different but complementary risks.

International Health Regulations

The revised International Health Regulations require countries to develop core capacities for detecting, assessing, and responding to public health events. These capacities include laboratory capabilities that meet international standards for biosafety and biosecurity.

The International Health Regulations also address the international transport of biological materials. Countries must ensure that specimens are transported safely and securely, with appropriate packaging, labeling, and documentation.

Biological Weapons Convention and UN Security Council Resolution 1540

The Biological Weapons Convention prohibits the development, production, and stockpiling of biological weapons. UN Security Council Resolution 1540 requires countries to implement measures to prevent the proliferation of weapons of mass destruction, including biological weapons.

These international instruments impose obligations on countries that have implications for individual laboratories. Laboratories handling dangerous pathogens must ensure that their materials are not diverted for hostile purposes and that their personnel are reliable.

National Regulations

National regulations for biosafety and biosecurity vary considerably between countries. Some countries have comprehensive regulatory frameworks that address both domains, while others have limited or fragmented regulations. Laboratories must be aware of the regulations that apply to their activities and ensure compliance.

China's regulatory regime for medical biotechnology has evolved over the past 40 years into a comprehensive system spanning the full cycle of research, application, and export. The system covers both security and ethics and is supported by multi-tiered laws and regulations. However, challenges remain in addressing the risks of technological convergence, clarifying regulatory boundaries, strengthening ethical constraints, and enhancing public engagement.

Emerging Challenges in Biosafety and Biosecurity

Synthetic Biology and Nucleic Acid Synthesis

Advances in synthetic biology are changing the landscape of biosecurity. The ability to synthesize DNA sequences on demand creates new risks, as individuals or organizations could potentially create dangerous pathogens without access to natural sources.

Order screening for synthetic nucleic acids has become a central element of biosecurity policy in several jurisdictions, including the United States, European Union, New Zealand, and the United Kingdom. However, global uptake remains uneven. Many providers, particularly in low- and middle-income countries, operate without explicit screening mandates. Data from the IBBIS Global DNA Synthesis Map indicate that only a small fraction of more than 700 known providers worldwide maintain publicly identifiable screening mechanisms.

The shift from organism-level controls to sequence-level governance of synthetic nucleic acids risks overburdening under-resourced institutions. Ambiguous definitions of sequences of concern, fragmented and overlapping regulatory triggers, and underdeveloped institutional screening and review capacities create gaps between policy intent and operational capacity.

Artificial Intelligence and Biotechnology

The convergence of artificial intelligence and biotechnology is transforming the life sciences and enabling rapid design, development, and analysis across the research lifecycle. However, this acceleration also heightens the risk of potential biological misuse.

In AI-enabled biology, capability is increasingly compositional, arising from interactions among data, models, infrastructure, and workflows. Risk no longer resides solely within individual components but in how they are connected. Safeguards that are effective in isolation may fail when systems are integrated. For example, nucleic acid sequence screening may not capture risks arising from generative systems that explore novel biological space beyond reference frameworks.

A relational approach to biosecurity treats interactions between components as explicit objects of design and governance. This approach emphasizes system-level sensing, preservation of context and uncertainty, buffering of perturbations, and alignment with shared values across distributed actors.

Mobile and Field Laboratories

Rapid response mobile laboratories play an important role in responding to emergencies such as outbreaks and humanitarian crises. These laboratories must operate in challenging environments with limited infrastructure and resources.

A scoping review of operational standards for field deployments of rapid response mobile laboratories identified five key workstreams: operational support and logistics, biosafety and biosecurity, laboratory information management system, quality management systems, and interoperability and coordination. The application of biosafety and biosecurity protocols is most addressed during the mission execution phase, particularly in the use of personal protective equipment and the implementation of decontamination and disinfection procedures.

Mobile laboratories face unique challenges in maintaining biosafety and biosecurity standards. They may lack the engineering controls of permanent laboratories, and they must operate in environments where security risks may be higher.

Professional Escalation Criteria

Laboratory personnel should know when to escalate concerns to supervisors, safety officers, or other authorities. The following situations warrant immediate escalation:

Biosafety Escalation

• Any exposure to a biological agent through needlestick, splash, inhalation, or other route
• Any spill or release of a biological agent outside the primary containment
• Any suspected failure of containment equipment, such as a biological safety cabinet that fails certification
• Any unexplained illness in a laboratory worker that could be related to occupational exposure
• Any observation of unsafe practices that could lead to exposure or release

Biosecurity Escalation

• Any discrepancy in inventory that cannot be explained
• Any unauthorized access to laboratory areas or storage facilities
• Any attempt to remove biological materials from the laboratory without authorization
• Any suspicious request for information about laboratory security or materials
• Any concern about the reliability or behavior of a colleague with access to dangerous materials

General Escalation

• Any situation where the laboratory lacks the resources or capacity to implement required biosafety or biosecurity measures
• Any regulatory requirement that the laboratory cannot meet
• Any emerging pathogen or new procedure for which existing risk assessments are inadequate

Escalation should be documented, and the person escalating should receive acknowledgment that their concern has been received and is being addressed. A culture that punishes reporting of concerns will quickly lose the information needed to prevent incidents.

Frequently Asked Questions

What is the main difference between biosafety and biosecurity?

Biosafety protects people and the environment from accidental exposure to or release of biological agents. Biosecurity protects biological materials from intentional theft, diversion, or misuse. Biosafety asks what could go wrong by accident, while biosecurity asks who could cause harm deliberately. Both are necessary components of a comprehensive biorisk management program.

Why do laboratories need both biosafety and biosecurity measures?

Laboratories need both because they address different types of risk. A laboratory with excellent biosafety practices can still be vulnerable to theft of dangerous materials. A laboratory with strong physical security can still experience accidental exposures if biosafety practices are weak. The two disciplines complement each other, and an integrated approach provides more complete protection than either alone.

How does risk assessment differ for biosafety and biosecurity?

Biosafety risk assessment focuses on the characteristics of the biological agent, the procedures performed, the equipment available, and the competence of personnel. Biosecurity risk assessment focuses on the attractiveness of the materials to potential adversaries, the vulnerability of the laboratory to unauthorized access, and the consequences of theft or diversion. Both types of risk assessment should be documented and reviewed regularly.

What are the key components of a laboratory biosecurity program?

Key components include inventory control and material accountability, physical security and access control, personnel reliability and training, secure transport and transfer procedures, and incident reporting and investigation. The level of security should be proportional to the risk associated with the materials being protected.

How should a laboratory respond to a biosafety incident?

The immediate priority is to protect people from further exposure. This may involve evacuation, decontamination, first aid, or medical evaluation. The incident should be reported to the laboratory supervisor and safety officer, and an investigation should be conducted to determine the cause and identify corrective actions. The incident should be documented, and lessons learned should be shared with all personnel.

How should a laboratory respond to a biosecurity concern?

Any concern about unauthorized access, missing materials, or suspicious behavior should be reported immediately to the responsible security or management personnel. The concern should be investigated promptly, and appropriate actions should be taken to protect the materials and the laboratory. Personnel should not attempt to confront suspected individuals themselves.

What training is required for laboratory personnel in biosafety and biosecurity?

All personnel who work with biological materials should receive initial training in biosafety and biosecurity before starting work, followed by refresher training at regular intervals. Training should cover the principles of both disciplines, the specific hazards of the materials handled, proper use of equipment, emergency procedures, and reporting requirements. Competency should be assessed through observation and testing, beyond attendance.

How do international regulations affect laboratory biosafety and biosecurity?

International instruments such as the International Health Regulations, the Biological Weapons Convention, and UN Security Council Resolution 1540 impose obligations on countries that affect individual laboratories. These obligations include implementing biosafety and biosecurity measures, ensuring safe transport of biological materials, and preventing the diversion of dangerous pathogens. Laboratories should be aware of the international frameworks that apply to their activities and ensure compliance with national implementing regulations.
