Locating these components outside the containment barrier will facilitate repairs, maintenance, testing and certification, cleaning, inspections, and emergency shut-off by personnel. Similarly, consideration should be given to the design of drainage piping for effluent decontamination systems such that it is readily accessible for repairs, maintenance, and inspection.

Limited access or restricted access to containment zone systems and controls contributes to both biosafety and biosecurity. Minimizing and shielding protruding obstructions e. Centralizing services including conduits, electrical wiring, and plumbing lines that are run through the containment barrier will reduce the number of penetrations that need to be sealed and tested for integrity. A communication system e. Communication systems allow the timely transfer of information gathered in the containment zone and are essential for communications between personnel in the event of an emergency.

Consequently, communication should be maintained with minimum interruptions during a power outage. Verification of communication systems confirms that they are operating as designed. Examples of communication devices include telephones, fax machines, intercom systems, two-way radios, panic buttons, computers, and notes or hand signals observed through a window. The HVAC system maintains inward directional airflow IDA , an essential component of the containment barrier in zones where it is required.

In cases of HVAC system failure, personnel need to be made aware immediately. It is important that alarms signalling HVAC system failure inform personnel both inside and outside the containment zone so that personnel are adequately informed to evacuate, to avoid entering the containment zone, to quickly initiate emergency procedures e. Ideally, building automation systems can be programmed to provide maintenance warnings or pre-alarms to help prevent HVAC system failure.

Locating the HEPA filter s as close as possible to the outside of the containment barrier minimizes the length of contaminated ductwork. Exhaust ductwork designed to withstand the maximum pressure achievable by the HVAC system when under extreme negative pressure, will prevent a biocontainment breach if the air supply or exhaust system malfunctions.

When designing HVAC systems for containment zones, consideration should be given to the appropriate placement of large equipment that can generate heat and disrupt airflow e. Additional factors such as the presence of cylinders of hazardous gases e. A change in room ventilation will affect the functioning of the BSC, and failure of the BSC can affect room ventilation.

BSCs are further discussed in Chapter Chemical fume hoods are hard-ducted to the exhaust ductwork, and will therefore be linked to room airflow i. A change in room ventilation will affect the functioning of the fume hood, and failure of the fume hood can affect room ventilation. Chemical fume hoods are not designed for the manipulation of infectious material or toxins, and consideration should be given to minimizing the placement of chemical fume hoods in high containment zones; instead, Class II B2 BSCs, which are designed to handle infectious material or toxins as well as volatile chemicals and radionuclides, should be considered.

Chemical fume hoods are further discussed in Chapter Appropriate design of supply and drain plumbing can contribute to containment by preventing the release of contaminated liquids into either the drinking water distribution system or the sanitary sewer. This is achieved by installing backflow preventers and isolation valves, which are required in CL2 LA zones i. Footnote 7 Capped or raised floor drains incorporated into large scale production areas will prevent the release of infectious material or toxins into sanitary sewers, and allow the material to be decontaminated before being released.

Drainage traps create a water seal that prevents contaminated air within the containment zone from entering the piping, sewer or effluent decontamination systems. Separating drain lines and associated piping prevents the contamination of drain lines and piping that service areas outside the containment zone.

The requirements pertaining to plumbing are specified in Matrix 3. The availability of handwashing sinks within the containment zone facilitates handwashing by personnel upon exit. It is preferable to have dedicated handwashing sinks, and to have them located near the points of exit from the containment zone. Locating handwashing sinks outside CL2 containment zones may be acceptable if appropriate measures e. The cost of hands-free faucets has become more reasonable in recent years, and they are rapidly becoming the norm in public washrooms.

All levels of containment should be encouraged to upgrade to hands-free faucets on handwashing sinks as facilities are renovated. Integration of dedicated decontamination technologies , such as autoclaves, effluent decontamination systems, and services to allow for full room gaseous decontamination, greatly impact the physical design of containment zones and present particular considerations during the design phase.

Decontamination, including autoclaves, effluent decontamination systems, and gaseous decontamination, is discussed in detail in Chapter This section provides guidance on the special physical considerations for these technologies when designing and building a containment zone. Autoclaves are used to sterilize materials and reagents, and to decontaminate waste prior to disposal.

Locating them outside the containment barrier will lead to additional procedures being put in place for the safe movement of contaminated waste. In high containment zones, autoclaves within the confines of the containment barrier allow for the decontamination of materials, including waste, prior to their removal from the containment zone.

Locating double-door barrier autoclaves on the containment barrier facilitates the process. Pre-vacuum autoclaves function by first pumping air out of the decontamination chamber, prior to decontamination. This air is contaminated and must be filtered e. Consideration should be given to locating pre-vacuum autoclaves such that the air filter is accessible for routine inspection e. Autoclaves function with steam self-generated or from a central supply that condenses upon cooling, leading to potentially contaminated liquid waste. Autoclave condensate can either be channelled to containment zone drains for decontamination along with other containment zone liquid waste, or go through an autoclave auto-decontamination cycle that decontaminates the condensate prior to its release.

It is important to note that it is the end user's responsibility to confirm that the auto-decontamination cycle provided with the autoclave has been programmed and verified for correct operation during the autoclave installation and that this cycle is effective against the pathogens or toxins being handled. Discharges from the autoclave chamber safety relief valves are similarly directed to containment zone drains, even when the body of the autoclave is located outside the containment barrier. In high containment zones, the effluent decontamination system should be designed to collect and treat all liquid waste generated within the containment zone e.

Biochemical tests for identification of bacterial pathogens

It may be possible to address this by the use of a sump with a feedback loop to secondary tanks. Effluent decontamination systems are discussed in Chapter 15 , and the applicable physical containment requirements are specified in Matrix 3. Accurate labelling of all drainage piping leading to an effluent decontamination system allows the correct identification of these components to facilitate a faster response in the event of a failure or leak.

Utilizing gravity flow by sloping drain piping towards the effluent decontamination system reduces the risk of blockage in the piping, as does a mechanism to break down e. Where the drainage system is directly connected to the effluent decontamination vessels i.

Should the need arise, rooms can be decontaminated in their entirety by chemical decontamination of all surfaces or by using gaseous decontamination methods CBS Matrix 4. Surfaces and materials e. The location of fumigation ports needed for certain gaseous methods should be carefully selected to facilitate effective decontamination. The containment zone contains physical structures and materials that contribute to the containment of pathogens and toxins as well as providing security measures biosecurity.

These include windows, doors, containment zone surfaces e. This section provides guidance on containment zone physical structures and materials in order to facilitate compliance with the requirements specified in the CBS. In CL2 laboratory work areas, non-fixed i. For CL2 SA zones, CL2 large scale production zones, large animal containment zones LA zones at all containment levels, and all high containment zones, fixed windows that are sealed maintain containment biosafety and biosecurity. Safety and security films and window glazing can protect against forced entry, breaking of window glass, and other environmental concerns, as well as reduce visibility into containment zones from the outside.

Windows that allow visual monitoring of activities in laboratory work areas, large scale production areas, and animal work areas inside high containment zones from an office or other area outside the containment barrier improves personnel safety and allows for quick emergency response and assistance. Other devices such as closed-circuit television CCTV may be an effective alternative where windows are not appropriate. Viewing windows into animal rooms and animal cubicles allow personnel within the containment zone to monitor animals without entering the rooms or cubicles; however, windows on the containment barrier are to prevent the public from viewing animal rooms, animal cubicles, and post mortem rooms [PM rooms] as this could pose a biosecurity risk and compromise animal well-being CBS Matrix 3.

A door is an integral part of the containment barrier that separates the containment zone from public and administrative areas, while also providing a security barrier to limit access to the zone. The door will be the location where entry requirements e. Security barriers i. Biosecurity and physical security considerations are further discussed in Chapter 6. Doorways should be constructed large enough to allow for the passage of any large pieces of equipment e. Anteroom doors are used to separate the "clean" areas from the "dirty" areas, and allow for the movement of personnel or animals into or out of the containment zone.

Preventing the anteroom doors from being opened simultaneously using an interlocking system will reduce the possibility of potentially contaminated air migrating outside the containment zone. Similarly, door interlocks and visual and audible alarms prevent personnel from opening both sides of a barrier autoclave or pass-through chamber simultaneously. In certain cases, it may be acceptable to use operational procedures to achieve the same intent as mechanical or electronic door interlocks. Manual overrides on mechanically or electronically interlocked doors e. This is critical in life-threatening emergency situations when personnel safety is the priority.

This can also be achieved with a tight fitting door and using tape and plastic film to create a seal around the door. Containment facilities need to be designed so that they can be easily cleaned and decontaminated. The design and choice of materials used for walls, ceilings, floors, and barrier devices are critical for the containment zone to have the structural stability to withstand internal and external stresses.

Cleanable and resistant surface materials and finishes e. Other examples of surfaces in work areas that may become contaminated as a result of the procedures in use or spills of infectious material and require decontamination include animal holding units, interiors of drawers, cabinets, and shelves. Non-absorbent materials may include stainless steel, epoxy resin surfaces, or chemical-resistant plastic laminate for benchtops, and urethane or vinyl for stools and chairs CBS Matrix 3.

Containment barrier surfaces that are resistant to scratches, stains, moisture, chemicals, heat, impact, repeated decontamination, and high pressure washing, in accordance with function, will prevent the release of pathogens and toxins, and protect against the contamination of inaccessible spaces e. Similarly, benchtops that are a seamless one-piece design or sealed at seams will prevent contamination.

Coved benchtops or installation of a backsplash sealed against the wall will provide a continuous barrier to prevent contaminated liquids from reaching inaccessible surfaces where the bench abuts a wall. Continuous, non-pervious floors that are coved up the walls and cabinets help prevent spills from penetrating underneath. Slip-resistant floors e. In animal containment zones, impact resistant floors can withstand the weight of animals and associated equipment without becoming gouged or cracked. In addition, floors can be designed to withstand prolonged contact with animal urine.

Due to the large volumes of liquid required to clean animal rooms, animal cubicles, and PM rooms, floors can be sloped directly toward the floor drains in order to prevent pooling of contaminated liquids. Using washable, hard non-porous paints on floors, walls, and ceilings will protect these surfaces and make them easier to clean and decontaminate. Solid-core materials e. Unfinished wooden and wood-finish walls or floors are not appropriate because they can absorb potentially infectious material, particularly liquids, making decontamination virtually impossible.

Wood should only be used when it is sealed properly to prevent the absorption of liquid contamination. Where used, it is important to frequently inspect it to identify early any scratches or other damage from routine wear and tear that may result in reduced resistance to liquids, thereby increasing risk of absorbing infectious material.

Surface materials that prevent the penetration of gases and liquids provide room integrity, facilitate surface and room decontamination, and help to contain any large volumes of contaminated liquids that may be present e. Requirements relating to materials and surfaces are specified in Matrix 3. Certain laboratory equipment will have specific operational needs and the location of large equipment should be considered when planning the floor space. For example, the operation of BSCs can be easily affected by air disturbances in their proximity, including as a result of nearby refrigeration equipment that generates a large amount of heat.

It is always important to position large and integral equipment e. Further safety considerations for equipment commonly used for biological work in laboratories are discussed in Chapter 12 ; large scale activities are further discussed in Chapter Furniture constructed from wood or with exposed wood surfaces is not practical in containment zones. Instead, non-absorbent materials, such as urethane or vinyl, can be used for stools and chairs in containment zones so that they are liquid-resistant and can be easily cleaned and decontaminated when necessary.

It is often preferable to have easily reconfigurable furniture e. Smooth rims and corners on furniture, drawers, benches, doors, handles, and shelving should always be considered to protect against compromising PPE e. In addition, spaces between benches, cabinets, and equipment should be accessible for cleaning and decontamination when necessary, as well as to allow for the servicing of equipment. For example, it is unadvisable to position a Class II BSC in a limited concave space, as this might not allow the BSC certifier adequate space to remove panels from the cabinet when performing on-site field testing and certification of the unit.

  • Controlled activities with human pathogens or toxins conducted in Canadian facilities , such as public health laboratories , teaching and research laboratories, diagnostic laboratories in hospitals, and vaccine production plants, are regulated under the Human Pathogens and Toxins Act HPTA and the Human Pathogens and Toxins Regulations HPTR. Footnote 1 Footnote 2 Importation of animal pathogens , or animals, animal products or by-products, or other organisms that carry an animal pathogen or part of one that retains its pathogenicity e.

    The PHAC is responsible for the regulation of human pathogens and toxins under the authority of the HPTA and the HPTR and the importation or transfer of terrestrial animal pathogens and toxins, with the exception of non-indigenous animal pathogens , emerging animal disease pathogens, and animal pathogens in animals, animal products, animal by-products, or other organisms, under the authority of the HAA and the HAR.

    The Canadian Biosafety Standard CBS ,2 nd Edition, is a harmonized national standard for the handling and storing of human and terrestrial animal pathogens and toxins in Canada. By condition of licence or animal pathogen import permit , the CBS establishes the criteria for any containment zone where human or terrestrial animal pathogens or toxins are to be safely handled or stored. A controlled activity that is not listed on the licence is not authorized under that licence. The licence also specifies the facility or facilities in which the controlled activities are authorized.

    An application to amend a licence can be submitted to add a new controlled activity or new facility not originally authorized on the licence. The person to whom the licence has been issued is identified as the "licence holder". The licence holder can be an individual person or an organization e. Selection of the licence holder is determined by the organization and can be supported by existing internal administrative oversight arrangements. As specified in Section 4 of the HPTA, the HPTA does not apply to a human pathogen or toxin that is in an environment in which it naturally occurs if it has not been cultivated or intentionally collected or extracted.

    This includes a human pathogen or toxin that:. On the condition that procedures are not performed to intentionally increase the concentration e. For example, primary specimens collected from humans e. As a result, such specimens do not require a licence and are not subject to any requirements in the HPTA. The natural environment of some human pathogens can also include a living animal host, or primary specimens, such as blood, plasma, excretion, other bodily fluids, tissue samples, body parts or carcass , collected from an animal host; however, a human pathogen in an animal that has been experimentally or intentionally infected is not in its natural environment and is therefore not excluded from the HPTA and HPTR and is subject to all requirements, including a licence.

    Human pathogens that are also animal pathogens i. There are several exemptions from the specific licence requirements under the HPTA. Even when a facility is exempt from the licence requirements of the HPTA and HPTR, persons knowingly conducting any controlled activity involving a human pathogen or toxin continue to have a responsibility to take all reasonable precautions to protect the health and safety of the public against the risks posed by that activity HPTA 6. Persons that are exempt from the licence requirements are still subject to other sections of the HPTA. For persons exempt from the licence requirements under the HPTA and HPTR, it is generally considered best practice to demonstrate, by following the physical and operational practice requirements specified in the CBS, that all reasonable precautions have been taken to protect the health and safety of the public against the risks associated with the materials in their possession.

    Additional guidelines are available from the PHAC to further support those who are exempt from the licence requirements where following the CBS requirements may not be achievable; please contact the PHAC directly for further information, or visit the PHAC website www. The PHAC issues four different types of licences, based on the inherent risks associated with the human pathogen s or toxin s i. Additional conditions of licence may also be imposed HPTA 18[4]. The licence holder is responsible to inform all persons conducting controlled activities authorized by the licence of its conditions HPTA 18[6].

    The licence holder and all persons conducting controlled activities under a licence must comply with those conditions HPTA 18[7]. The "Pathogen and Toxin Licence" is the regulatory authorization document issued by the PHAC to a licence holder and is both a licence for controlled activities with human pathogens and toxins under the HPTA, and, when also identified on the document itself, an animal pathogen import permit for the importation or movement of terrestrial animal pathogens under the authority of the PHAC, in accordance with the HAR.

    The importation of animal pathogens is further discussed in Section Applications for new licences or for amendments or renewal of licences can be submitted electronically through the Biosecurity Portal, accessible through the PHAC website www. Before issuing a licence, the PHAC must be of the opinion that the conduct of the controlled activity or activities with human pathogens and toxins in any facility under that licence would not pose undue risk to the health or safety of the public.

    Therefore, the amount and detail of information submitted in a licence application is proportional to the risk and types of human pathogens and toxins. For example, there are heightened security risks associated with SSBAs; therefore, the PHAC will require documentation that demonstrates how these risks will be controlled and managed for any licence application for controlled activities with an SSBA. As such, applicants applying for a licence involving SSBAs are required to submit their biosecurity plan, in addition to the requirement to obtain or apply for HPTA Security Clearances for any individuals working under that licence.

    Furthermore, as specified in Section 3 of the HPTR, an applicant who intends to carry out scientific research , before issuing the licence, the PHAC must determine that the person has developed a plan that sets out administrative measures for managing and controlling biosafety and biosecurity risks during the period in which the licence is in effect. These Plans are intended to be very high level i.

    Further details on the Plan, including a summary of the elements to be included, can be found in Appendix A. Administrative controls are further described in Chapter 5. The importation into Canada of an animal pathogen or part of one that retains its pathogenicity e. The HAA and HAR detail specific requirements and obligations of a person handling material imported under an animal pathogen import permit.

    The PHAC issues a regulatory authorization document titled a "Pathogen and Toxin Licence", which is an animal pathogen import permit for the importation or movement of terrestrial animal pathogens under the authority of the PHAC, in accordance with the HAR, when identified on the document itself. The movement to another location e. Likewise, introduction into an animal e. Please refer to the conditions of permit for further information on prohibitions and restrictions that may also apply. Before issuing an animal pathogen import permit, the CFIA must be satisfied that the activities for which the permit is issued would not result in the introduction into Canada, into another country from Canada, or the spread within Canada of the pathogen HAR [1.

    Applicants of an animal pathogen import permit from the CFIA may be subject to facility certification or compliance verification to demonstrate satisfactory evidence that the containment zone meets the necessary requirements. For higher containment zones, the facility certification process may include an onsite inspection, a review of as-built drawings and specifications, commissioning and performance and verification testing reports of critical physical containment systems, the Biosafety Manual , the containment zone SOPs, and, for work with RG4 pathogens, a review of training records.

    For lower containment zones, compliance verification could include the completion of a compliance checklist. Facilities certified by the CFIA may require annual recertification. Recertification may comprise a review of documentation such as program intent and the performance and verification testing reports of critical containment systems to verify that the zones continue to comply with the requirements specified in the CBS. A request to change the program intent is to be submitted to the CFIA along with updated SOPs and the Biosafety Manual before implementation of any changes to the program intent.

    Changes to program intent may include, but are not limited to, the introduction of new pathogens, new animal species, or changes to procedures which could alter the risk of personnel exposure or the risk of pathogen release from the containment zone. In some cases, an on-site inspection may be required by the CFIA to verify continued compliance before facility recertification is granted.

    Further information, instructions, checklists, and forms on the specific documents required and the facility certification and recertification process can be obtained from the CFIA website or by contacting the CFIA directly. Zoonotic pathogens are capable of causing disease in both human and animal hosts. This section describes additional federal legislation that may also impact the importation, production, and the exportation of pathogens and toxins beyond the regulatory authorities of the PHAC and the CFIA.

    The Canada Border Services Agency CBSA provides integrated border services that support national security and public safety priorities and, at the same time, facilitate the free flow of persons and goods. The activity of importing pathogens and toxins by an individual or an entity for sale or for any industrial, occupational, institutional, or other similar use in Canada is considered by the CBSA to be importing for "commercial use".

    Footnote 10 The Government of Canada has established an integrated Single Window Initiative SWI , administered by the CBSA, to reduce the paper burden associated with goods imported for commercial use by providing an electronic interface for all required importation documentation. Footnote 11 Through the SWI, importers or licence holders and their customs brokers can electronically submit import or export data, accounting documents, and any other information to the CBSA that is required to comply with and any relevant importation legislation.

    In turn, the CBSA transmits this information to the appropriate government department s or agency or agencies responsible for regulating the goods to assess the information and provide any necessary border-related decisions. This electronic interface streamlines and simplifies the importation process by permitting pre-border clearance of imported goods, thereby reducing delays at the border. This also facilitates the processing of low-risk goods through customs and allows resources to focus on higher-risk goods that could pose potential threats to Canada's safety and security.

    In order to complete importation documentation, it is necessary for licence holders or importers to provide their appropriate Pathogen and Toxin Licence number or animal pathogen import permit number, the Canadian Product Category CPC , and the Intended Use Code IUC of the imported material in advance to their purchasing department or customs broker.

    Footnote 12 At the time of publication, SWI is not a mandated process. Interested brokers have commenced the certification process with CBSA to move to SWI, and will continue to do so during the implementation phase that is scheduled to be complete in When importing an animal pathogen under an animal pathogen import permit issued by the CFIA, the import permit holder or delegate is responsible to make certain that a copy of the animal pathogen import permit and any other necessary importation documentation accompanies the shipment across the border.

    The CBSA then makes a final decision. Footnote 15 Footnote 16 A new substance e. This legislation aims to protect both the environment and human health from potentially harmful new substances that are animate products of biotechnology i. The NSNR O applies to both microorganisms used in microbial products or to produce various biomolecules, as well as a variety of "higher" organisms, such as fish, livestock, and insects depending on the use. The NSNR O includes exemptions for microorganisms that are research and development organisms not intended for introduction outside of a containment facility.

    Persons conducting research and development activities with new microorganisms resulting from biotechnology should refer to the NSNR O for a complete understanding of the exemptions and when they can be applied. Footnote 17 Footnote 18 Footnote 19 Footnote 20 The NSNR O does not apply to a microorganism that is imported for use that is regulated under other acts or regulations e. Environment and Climate Change Canada, in conjunction with Health Canada, is responsible for conducting environmental and indirect human health risk assessments, respectively, for new organisms in products regulated under the Food and Drugs Act e.

    When transporting regulated materials to another country, it is the responsibility of the person sending the material i. For example, before shipping a sample of an RG2 human pathogen or toxin to an address in the United States, the person intending to export the material should verify and document that the intended recipient has access to and will work with the material in a suitable containment facility that meets biosafety level 2 as described in the current edition of Biosafety in Microbiological and Biomedical Laboratories , published by the United States Centers for Disease Control and Prevention CDC and the United States National Institutes of Health NIH.

    Footnote The BTWC aims to prevent the proliferation of biological and toxin weapons through the prohibition of the development, production, stockpiling, acquisition, or retention of microbial or other biological agents or toxins, whatever their origin or method of production, of types and in quantities that have no justification for prophylactic, protective, or other peaceful purposes, and of weapons, equipment, or means of delivery designed to use such agents or toxins for hostile purposes or in armed conflict.

    To help fulfil their obligations under the BTWC and the Chemical Weapons Convention CWC , many national governments around the world, including Canada, participate in the informal forum known as the Australia Group and have developed harmonized export controls for chemical weapons and chemical weapon precursors, human, animal, and plant pathogens and toxins with dual-use potential , and dual-use manufacturing facilities, equipment, technology, and software, as well as other items that could be used to test or disseminate controlled chemical or agents or for protection against them. The Australia Group maintains common lists for export control, including the List of Human and Animal Pathogens for Export Control, which can be viewed on its website www.

    For more information, please contact GAC or visit its website www. It is important to note that while some of the definitions provided in the glossary are universally accepted, many of them were developed specifically for the Canadian Biosafety Standard CBS , 2 nd Edition or the Canadian Biosafety Handbook CBH , 2 nd Edition; therefore, some definitions may not be applicable to facilities that fall outside of the scope of the CBS and the CBH.

    The words and phrases defined in this glossary appear in bold type upon first usage in each chapter throughout the CBH. The responsibility for the acts and regulations listed below may be shared amongst multiple regulatory authorities agencies or departments. There are characteristics of research environments where the need for innovation may be at odds with the regulatory framework intended to protect the health and safety of the public from the risks posed by human pathogens and toxins.

    The research sector also faces additional risk factors, such as autonomous research and researchers, perceived diffuse accountabilities, and complex reporting and governance structures, which are not always present in other sectors e. A licence will not be issued to an applicant without the submission of a Plan; however, the quality and completeness of the Plan will not delay the issuance of a licence.
