Human & Animal Health Laboratories: from Concept to Commissioning Yanko Ivanov & Ragip Bayraktar, EU Technical Assistance to Avian Influenza Preparedness & Response Project, EU

Slide 2

Contents Biosafety & Biosecurity contemplations and p rinciples Assessment for research facility need and choice –making procedure and method of reasoning for interests in labs or not. Assurance of capacities and extent of work in a lab Commissioning and o perations. Plan and c onstruction Issues.

Slide 3

Laboratory biosafety & biosecurity - definitions "Research center biosafety" is the term used to depict the regulation p rinciples, innovations and practices that are executed to anticipate inadvertent introduction to pathogens and poisons, or their unintentional discharge. "Research center biosecurity" alludes to institutional and individual security m easures intended to keep the misfortune, burglary, abuse, preoccupation or purposeful arrival of pathogens and poisons.

Slide 4

Laboratory biosecurity as a supplement to l aboratory biosafety Laboratory biosafety and biosecurity moderate diverse dangers, however they share a shared objective: keeping v aluable organic materials securely and safely inside the territories where they are utilized and put away. Great lab biosafety rehearses fortify and reinforce lab biosecurity frameworks.

Slide 5

Conflicts ( Biosafety versus Biosecurity) Accountability Compliance SOP\'s Emergency schedules GLP Safety cupboards Personal wellbeing hardware Inventory control Access control Transfer security Physical security Information security Biosafety regulation Biosecurity Incident reporting Incident reaction arranging Revision Training Supervised by selected B iosafety officer Regulated by national workplace wellbeing law Supervised by delegated B iosecurity or Biosafety officer Should counsel with law implementation authorities and security specialists

Slide 7

Biosafety l evels BSL1 - specialists not known to bring about illness (no or low individual and group chance) . BSL2 - specialists that cause human or creature malady s with direct individual or low group chance (e.g. blood borne ailments) . BSL3 - indigenous/extraordinary operators connected with human infection and with potential for vaporized transmission - high individual hazard (respiratory) low group chance) BSL4 - hazardous/intriguing specialists of life debilitating nature – genuine sicknesses promptly transmitted .

Slide 8

Biosafety Level 3 Risk Assessment What is the common host of the organic specialist? Does the specialist cross species boundaries? Is it a wild-sort specialist or weakened? Is the specialist irresistible for an ordinary solid grown-up? What impact will the operator have on a grown-up if immunocompromised? on the off chance that pregnant?

Slide 9

Biosafety Level 3 Risk Assessment What is the method of transmission for the specialist? - contact, -mucous layer presentation, -ingestion, -immunization, -inward breath What volume of the operator is being controlled? What is the centralization of the operator? What is the irresistible measurement of the specialist?

Slide 10

Biosafety Level 3 Risk Assessment Prophylaxis What, if any inoculations are required? What pharmaceuticals are accessible? What is the viability of prophylaxis? Post-introduction What are the counter microbial specialists accessible for treatment? What is the viability of treatment?

Slide 11

Relation of hazard gatherings to biosafety levels, practices and hardware

Slide 12

Summary of biosafety level necessities BIOSAFETY LEVEL 1 2 3 4 Isolation of research facility No Yes Room sealable for sterilization No Yes Ventilation: — internal wind stream No Desirable Yes — controlled ventilating framework No Desirable Yes — HEPA-separated air deplete No Yes/No b Yes Double-entryway section No Yes Airlock No Yes Airlock with shower No Yes Anteroom No Yes — Anteroom with shower No Yes/No c No Effluent treatment No Yes/No c Yes Autoclave: — on location No Desirable Yes — in lab room No Desirable Yes — twofold finished No Desirable Yes Biological security cupboards No Desirable Yes Personnel wellbeing checking capabilityd No Desirable Yes

Slide 13

BIOSAFETY AND BIOSECURITY LABORATORY DESIGN CRITERIA Laboratory area Wipe-clean surfaces H eating, ventilation and aerating and cooling (HVAC) framework Directional wind stream and course antagonistic weight Laboratory furniture and gear Laboratory rooms, size and introduction Sample gathering Double entryway autoclave and purification chamber for strong waste materials Water supply and sewerage framework Electrical framework

Slide 14

Essential Building Principles Primary c ontainment boundary is the main obstruction amongst specialist and man (, for example, gloves, outfits, covers, biosafety cupboards, respiratory assurance and so forth.) Secondary c ontainment hindrance is the hindrance amongst operators and environment ( water/air proof rooms, air taking care of and filtration, airtight chambers, showers, clothing, sewage treatment, squander transfer, sterilizers, repetitive administrations and hardware and material specialties. Tertiary c ontainment boundary speaks to an extra hierarchical obstruction with the physical operation with things, for example, dividers, wall, security, isolate and creature avoidance zones.

Slide 15

Work stream contemplations During the programming stage it is basic to characterize how different components are prepared, including creatures (perfect and grimy), individuals, squanders (corpses, strong, other), specimens from creatures, clothing, encourage and bedding (if utilized).

Slide 16

The control hindrance s The regulation boundary s ought to be physical obstruction s built with a progression of coordinated building segments to frame a hermetically sealed inside environment isolate from the encompassing examination environment and neighboring group. The obstruction is likewise to be characterized by operational practices – cases of these "optional boundaries" incorporate work zones that are separate from open regions, disinfecting, shower and hand-washing methodology and gear, unique ventilation frameworks, directional wind stream using pneumatic force differentials, twofold entryway autoclaves, fluid waste treatment, wearing of individual defensive hardware (and expulsion upon exit) and limited staff get to.

Slide 17

Specimen Reception, Dispatch Area and "Grey Areas" A great example gathering would be a detached control region, yet a "grey area", for the preparatory treatment of symptomatic examples by experienced pathology work force. This would guarantee the right development of tests to research centers or post-mortem examination. An example gathering situated by the post-mortem range would coordinate the arrangement of controlled development of materials into the safe labs or creature offices. A "grey area" would likewise be a fitting zone to hold reagent anticipating innocuity tests or while inactivation is demonstrated. Tests bound for other reference labs might be securely expelled from the "grey area" without an impression of conceivable unusual pollution that may happen if the specimens were controlled in the high regulation labs before they are evacuated.

Slide 18

Security and related s ystems Typically there are different operational zones inside regulation offices. Get to control to one zone does not really give get to control to all rooms or ranges inside that zone. There are different projects that require singular get to control for the suitable faculty. Terminate caution

Slide 19

Security Zone 1: Property Protection Area (uncontrolled) • The whole building ought to screen entrance zones with CCTV cameras • Employee/guest stopping ought to have CCTV observing • Rear Loading docks ought to have CCTV checking • The electrical transformer vaults ought to be secured

Slide 20

Security Zone 2: Limited Areas/Non-Containment These zones require an essential level get to control qualification (nearness card) to enter. Cards ought to be coded to allow passage into particular Limited Areas in light of the need to get to. Lab halls (non-regulation) Loading dock stockpiling accepting territories and creature conveyance airtight chambers

Slide 21

Security Zone 3: Exclusion Area/Non-Containment This regions straightforwardly bolster control operations and require a third level card get to control Housing creature getting isolated space Clean autoclave rooms Basement region where fluid treatment framework is found Mechanical penthouse serving all HEPA channels and Air Handling Units, debilitate fans Building operation control ranges obliging building computerization frameworks

Slide 22

Security Zone 4: Exclusion Areas – Containment These zones are assigned as Secondary Containment Spaces in which the plan and get to is controlled essentially to permit specialists and administrators into the office. Passage into these zones will require two-level get to control, nearness card and PIN and additionally biometric. Exit from these ranges will require the vicinity card. All doorways will have a CCTV camera for checking. • CL3 lab shower entrance zone • CL3 cleaning airtight chambers

Slide 23

Security Zone 5: Exclusion Areas – Containment These territories are assigned as Lab Containment Spaces or concentrated regions in the plan. Section and leave will require keypad passage of a PIN and additionally biometric, which approves get to just to particular modules or spaces. All zones will have CCTV and movement discovery. • CL3 research facilities • CL3 creature holding rooms

Slide 24

Security Zone 6: Exclusion Areas – Containment Pathogen Storage Freezers All coolers ought to have entry control. All rooms are furnished with extra security highlights including movement discovery, doo
