Biological Safety Policies
6.1 – Registration of Materials Potentially Infectious for Humans
The Environmental Health and Radiation Safety Department (EHRS) maintains a registry of all Temple University research laboratories and personnel working with human pathogens or human blood, tissues, and body fluids. In addition, there are specific licensing requirements for individuals who possess, use, handle, store, and transfer SBAs that have the potential to pose a severe threat to both human and animal health, as well as plant and livestock health..
EHRS will complete the Human Pathogen Registration Document (HPRD form EHS 6.1F-001) after the IBC registration form is approved. The Human Pathogen Registration Document must be completed by individuals for any research with any organism known or suspected to cause infections in humans. All these research protocols require Institutional Biosafety Committee approval prior to initiation of research.

6.2 – Biosafety Audit Program
In order to assure that operations dealing with microorganisms are conducted safely and in accordance with federal and Pennsylvania regulations, policies must be available that define criteria for inspections. The Temple University policy on biosafety inspections is based on biosafety levels (BSL 1, BSL 2, BSL 3 and BSL 4) of facilities and organisms as defined in Biosafety in Microbiological and Biomedical Laboratories (CDC·NIH)
- Biological Materials
- Authorized Biological Agent Users
- Special Biological Agent Users
- Special Biological Agent & Toxin Audit Program

6.3 – Good Laboratory Practices
Regulations of the Food and Drug Administration dealing with Good Laboratory Practices are prerequisites for acceptability of the results of certain studies. These regulations (21 CFR 58) contain detailed descriptions of personnel, facilities, equipment, operation, quality assurance and a number of other areas. As a matter of policy, Temple University complies with Good Laboratory Practices regulations and the Environmental Health and Safety Department provides services required by the Good Laboratory Practice.
6.4 – Biosafety Universal/Standard Precautions
Federal and Pennsylvania regulations require the development and implementation of precautions to avoid infection of those who may be in contact with potentially contaminated biological materials. Because a microbiological analysis of every biological sample is impractical, as a matter of policy and consistent with federal and Pennsylvania regulations, it is assumed that blood and certain other body fluids are contaminated with infectious agents. In addition, tissues; various body fluids; materials derived from cultures containing infectious materials notably HIV or HBV; and equipment that has been in direct contact with infectious materials are considered to be contaminated.
Both federal and Pennsylvania regulations specify universal/standard precautions, engineering controls and personal protective equipment that can be applied for protection of those who may be in contact with potentially contaminated materials.
Specific safety requirement is as identified in BMBL.
6.5 – Exposure Control Plan
Federal and Pennsylvania regulations on bloodborne pathogens describe certain requirements to control the exposure to bloodborne pathogens.
The policy of Temple University for control of hazardous materials, including bloodborne pathogens, relies upon the following principles:
- The concept of keeping exposure to hazardous materials as low as reasonably achievable (ALARA) must be applied to the design and performance of all activities.
- Laboratory principal investigators or supervisors must assure that all activities in their respective areas are conducted safely (Policy No. 1.4).
- The severity of response to a problem will be consistent with its potential impact.
- Each individual is fundamentally responsible for his/her actions.
- Employees must be provided with the appropriate personal protective equipment and training.
- Engineering controls must be in place.
Consistent with these principles, the Temple University Exposure Control Plan consists of the following policies:
Policy No. 6.8 provides criteria for exposure determination. Each administrative unit (department, division, etc.) is responsible for identifying those employees that have an exposure potential to bloodborne pathogens.
The Exposure Control Plan will be reviewed and updated annually to reflect changes in technology that eliminates or reduces exposure to bloodborne pathogens.
Temple University Health System: Consideration and implementation of appropriate commercially available and effective safer medical devices designed to eliminate or minimize occupational exposure is the responsibility of the Temple University Health System Sharp Object Prevention Task Force Committee (TUHS SOIP TFC). A copy of the minutes from these meetings will be forwarded to EHS by the Infection Control Department of Temple University Hospital on a quarterly basis and attached to the Exposure Control Plan as evidence of compliance with the Bloodborne Pathogens Standard, effective April 18, 2001.
Evaluation and Selection of Effective Engineering and Work Practice Controls
Temple University Health System: The Administration of all Temple University Health System entities will solicit input from non-managerial employees responsible for direct patient care who are potentially exposed to injuries from contaminated sharps in the identification, evaluation, and selection of effective engineering and work practice controls. The documentation of this solicitation and feedback will be a part of the minutes of the TUHS SOIP TFC and forwarded to EHS for attachment to the Exposure Control Plan as referenced above. A copy of the evaluation tool completed when evaluating new safety devices will be maintained by the Infection Control Department of each TUHS institution and are available for inspection at any time upon request.
All employees with exposure potential to bloodborne pathogens will receive an initial training and an annual retraining. The core of Temple University training is the initial training provided for Level III employees (Policy No. 3.2). However, members of the faculty and those with previous training may receive an abbreviated training.
The Temple University Laboratory BioSafety Guide contains essential elements of universal/standard precautions, engineering controls, and personnel protective equipment. Policy No. 6.4 incorporates relevant sections of that guide by reference.
It is the Temple University policy to offer Hepatitis B virus (HBV) vaccination to all that potentially are exposed to bloodborne pathogens. Policy No. 6.7 describes the details of the Temple University approach.
HIV Research Laboratories
Certain laboratories engaged in research in HIV must undertake additional actions beyond those required for other facilities. Policy No. 6.10 describes these requirements.
Sharps Injury Log
A sharps injury log will be maintained by Occupational/Employee Health for recording of percutaneous injuries from contaminated sharps. The information in the sharps injury log shall be recorded and maintained in such a manner as to protect the confidentiality of the injured healthcare worker. The sharps injury log shall contain, at a minimum, the following:
- The type and brand of the devices involved in the incident
- The department or work area where the exposure incident occurred
- Explanation of how the incident occurred.
This sharps injury log will be maintained for 5 years after the date of the incident.
Despite best efforts to avoid exposure to bloodborne pathogens, provisions must be made to treat those who may have been exposed to these pathogens. See Temple Universitry Hospital (TUH ) policy 950.130, 950.130 (A) and 950.130 (B) or department specific policy on Post Exposure follow-up.
Temple University adheres to all regulations published in OSHA’s Recordkeeping Rule (29 CFR 1904). All sharps injuries involving contaminated objects are reported on the OSHA 300 Log of Work-Related Injuries and Illnesses and the OSHA 301 Injury and Illness Incident Report by the Temple University Worker’s Compensation manager or his designee. This new rule will become effective January 1, 2002. Until then, a sharps injury log must be maintained at all times as set forth by the new Bloodborne Pathogens Standard.
Infectious or Biological Waste
Temple University's management of infectious or biological waste is described in Policy Nos. 2.3, 2.4, 2.5 and 2.6.
All policies in the Environmental Health and Radiation Safety Handbook, including those related to biosafety, are periodically reviewed and revised, if necessary.
6.6 – Management of Spills of Biological Materials
Temple University has a policy for responding to uncontrolled releases or accidental spills of biological materials. (Internet Link: Centers for Disease Control Special Biological Agents)
In case of a spill of blood or other biological liquids in laboratories, principal investigators or supervisors are responsible for responding to any release of biological material and must assure that the cleanup occurs as quickly as possible. They must also assure that no unauthorized person enters the laboratory before the cleanup is completed.
PI/supervisors must assure the area, equipment, and/or plumbing are disinfected prior to any maintenance or repair.
6.7 – Hepatitis B Vaccination
In compliance with federal and Pennsylvania regulations, Temple University offers Hepatitis B vaccine to all that are potentially exposed to bloodborne pathogens (See Policy No. 6.5). The vaccination is available through employee health departments. Employees whose previously administered antibody testing indicates immunity, or those who may not be vaccinated for medical reasons, are exempted from the HBV vaccination
Employees have the right to refuse the vaccination. Those who decline the HBV vaccination must fill out Environmental Health and Radiation Safety form 6.7F-001. Those who decline the HBV vaccination initially may opt to receive the vaccine at any time.
6.7F – Hepatitis B Vaccine Declination
Declination form can be found here.
6.8 – Exposure Determination
In order to assure that individuals who have an exposure potential to bloodborne pathogens receive appropriate training, information and support, it must be determined who is covered by the Temple University policy. Due to the diversity of activities at Temple University, it is impractical to identify job categories that are exposed to bloodborne pathogens. Instead, broad categories of jobs are identified realizing that not all employees in those categories have exposure potential to human blood or other potentially infectious material. The following criteria are used to determine the exposure potential to bloodborne pathogens:
- All who in the course of their employment come in contact with patients (health care workers).
- All who in the course of their employment come in contact with developmentally disabled persons.
- All who work or come in contact with blood or other potentially infectious materials.
- Safety and emergency response personnel.
The following individuals are not covered by this policy because they are not considered to be potentially exposed to bloodborne pathogens:
- Medical and nursing faculty and staff who do not come in contact with patients.
- Employees of Facilities Management including personnel involved in plumbing and in heating, ventilation and air conditioning (see Policy No. 6.6).
Individuals, who are employed by Temple University and have an exposure potential in other institutions, must inform the Environmental Health and Radiation Safety Department so that appropriate arrangements are made to assure consistency in compliance with federal and Pennsylvania regulations.
The following contains a listing of selected job categories. All administrative units will be asked to identify employees in those job categories with an exposure potential based on criteria identified in this policy.
A. Employees having the following job classifications have occupational exposure to blood or other potentially infectious materials:
- Dentists, Dental Laboratory Technicians, Dental Assistants
- Nurses (Registered nurses, licensed practicing nurses)
- Nurses' Aides
- Clinical Laboratory Technologists, Technicians, and Aides
- Clinical Dental Hygienists
- Physical Therapists
- Occupational Therapists
- Sports Trainers
- Housekeeping Staff responsible for patient areas and laboratories at Temple University Health System
- Housekeeping staff responsible for laboratories where infectious materials/blood are handled
- Student Health Staff
- Occupational Health Staff
- Blood Bank Technicians
- Security Personnel
B. Certain employees in the following job classification may have exposure to blood or other potentially infectious materials:
- Faculty in the School of Medicine, Podiatry, Dentistry, and Biology
- Staff of Environmental Health and Safety
- Housekeeping staff responsible for areas related to athletes, dormitories, or where research with blood or infectious material is performed.
- Dialysis Personnel
- Facilities Management Personnel
- Biomedical Engineering
- Patient transportation personnel
List of tasks and procedures in which those listed in B. have occupational exposure:
- Contact with blood or other potentially infectious materials
- Performing patient care
6.9 – Inspection and Monitoring of Sterilizer Facilities
Steam sterilization of infectious material utilizes saturated steam within a pressure vessel (known as a steam sterilizer) at temperatures sufficient to kill infectious agents present. Various government agencies and consensus organizations have recommended periodic inspection of steam sterilizers. Accordingly, this policy requires an annual inspection of steam sterilizers, as well weekly efficacy validation tests, to ensure effective treatment.
The principal investigators or supervisors of steam sterilizers are required to ensure that steam sterilizers are inspected at least annually. The inspection should consist of a calibration for temperature and pressure, using an instrument approved by the National Institute of Standards and Technology. In addition, the steam sterilization process must be monitored on a weekly basis or 40 hours of operation, which ever is sooner, with a biological indicator (Bacillus stearothermophilus).
The principal investigators or supervisors are required to maintain records on the annual inspection and weekly efficacy validation. These records must be produced upon demand.
6.10 – HIV, SIV, HBV, and HCV Research Laboratories
Consistent with federal and Pennsylvania regulation, it is Temple University policy that research laboratories that use Human Immunodeficiency Virus (HIV), Simian Immunodeficiency Virus (SIV), Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV) must take additional precautions to assure a safe operation.
For the purposes of this policy, an HIV, SIV, HBV or HCV laboratory is defined as a facility engaged in the culture, production, concentration, experimentation with or manipulation of either one of these viruses. However, clinical or diagnostic laboratories engaged solely in the analysis of blood, tissues, organs or body fluids are not included in this policy.
Standard microbiological practices and special practices (EHRS Laboratory Biosafety Guide, NIH Guidelines for Research Involving Recombinant DNA Molecules and Biosafety in Microbiological and Biomedical Laboratories) must be used when working with HIV, SIV, HBV, HCV or other potentially infectious materials. In addition, these laboratories must follow legal requirements promulgated by the Occupational Safety and Health Administration (OSHA) Bloodborne Pathogens Standards-29 CFR 1910.1030(e). These research activities must be conducted in a Biosafety Level 2 (BSL-2) facility using BSL-3 practices unless only research is involved blood, body fluid or tissue contaminated or potentially infected can be performed with BSL-2 practices.
Activities involving large-scale volumes or preparation of concentrated HIV, SIV, HBV or HCV must be conducted at BSL-3 facility and practices. Animal studies involving non-human primates (NHP) and other animals infected with HIV, SIV, HBV or HCV must be performed in Animal BSL-2.

- Class II Biosafety Cabinet (BSC): The Class II (Types A1, A2, B1 and B2) BSCs provide personnel, environmental and product protection. Airflow is drawn into the front grille of the cabinet, providing personnel protection. In addition, the downward laminar flow of HEPA-filtered air provides product protection by minimizing the chance of cross-contamination across the work surface of the cabinet. Because cabinet exhaust air is passed through a certified HEPA filter, it is particulate-free (environmental protection), and may be recirculated to the laboratory (Type A1 and A2 BSCs) or discharged from the building via a canopy connection. Exhaust air from Types B1 and B2 BSCs must be discharged to the outdoors via a hard connection. All Class II cabinets are designed for work involving microorganisms assigned to biosafety levels 1, 2 and 3.
- Class III BSC: The Class III BSC (Figure 8) was designed for work with highly infectious microbiological agents and for the conduct of hazardous operations and provides maximum protection for the environment and the worker. It is a gas-tight (no leak greater than1x10-7 cc/sec of SF6 at 3 inches pressure Water Gauge) enclosure with a non-opening view window. Access for passage of materials into the cabinet is through a dunk tank, that is accessible through the cabinet floor, or double-door pass-through box (e.g., an autoclave) that can be decontaminated between uses. Reversing that process allows materials to be removed from the Class III BSC safely. Both supply and exhaust air are HEPA filtered on a Class III cabinet. Exhaust air must pass through two HEPA filters, or a HEPA filter and an air incinerator, before discharge to the outdoors. Airflow is maintained by a dedicated, independent exhaust system exterior to the cabinet, which keeps the cabinet under negative pressure (minimum of 0.5 inches of pressure Water Gauge).
6.11 – Shipment and Importation/Exportation of Biological and Infectious Materials
The U.S. Department of Transportation (DOT), the US Department of Health and Human Services’ Centers for Disease Control and Prevention (CDC), the U.S. Postal Service (USPS) and the International Air Transport Association (IATA) all have requirements that influence the shipping of dangerous goods from Temple University and Temple University Health System. Infectious substances are one of several types of dangerous goods that may be offered for shipment.
Any person wishing to submit a dangerous good for shipment must first receive training to do so from Environmental Health and Radiation Safety. The purpose of this policy is not to substitute for training, but to provide an overview of the regulations that pertain to the shipment of biological and infectious substances, as well as to the governmental agencies regulating the permitting processes.
Infectious Substances are substances known to contain, or reasonably expected to contain pathogens. Pathogens are microorganisms (including bacteria, viruses, rickettsia, parasites, and fungi) or recombinant microorganisms (hybrid or mutant) that are known or reasonably expected to cause infectious disease in humans or animals.
Infectious substances include;
- all cultures containing or suspected of containing an agent that may cause infection.
- human or animal samples that contain such an agent in quantities sufficient to cause infection, should an exposure to them occur due to a transport mishap
- sample(s) from a patient with a serious disease of unknown cause
- other specimens not included above and designated as infectious by a qualified person, e.g., a physician, scientist, nurse, etc.
Diagnostic Specimens are any human or animal material including, but not limited to, excreta, secreta, blood and its components, tissue and tissue fluids, being transported for diagnostic or investigational purposes, but excluding live infected animals. Diagnostic specimens resulting from medical practice and research are not considered a threat to public health.
However, if during transport exposure to a specimen could result in an infection, the specimen must be packaged, labeled and transported as an infectious substance.
Diagnostic specimens meeting the definition of the World Health Organization (WHO) Risk Group 4 (biological agents with high risk to the individual and to the community) must be classed and transported as Infectious Substances.
Biological Products are those products derived from living organisms that are manufactured and distributed in accordance with the requirements of national governmental authorities that may have special licensing requirements. They are used for prevention, treatment, or diagnosis of disease in humans or animals, or for development, experimental or investigational purposes related thereto. They include, but are not limited to, finished or unfinished products such as vaccines and diagnostic products.
Training: All persons wishing to submit packages containing dangerous goods, including infectious substances, must become certified to ship dangerous goods by attending training. Certification must be renewed every two years. Contact EHRS to arrange for training.
Training will include;
- Classification and Identification of the material
- Packaging Requirements
- Marking and Labeling the Package
- Preparing the Shipping Papers
Record Keeping: All records must be retained for three (3) years from the date of shipment.
6.12 – Select Biological Agents
To comply with the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 and the Agricultural Bioterrorism Act of 2002, Temple University prepared this guide for the possession, use, handling, storage, and transfer of select biological agents and toxins (SBA) that have been determined to have the potential to pose a severe threat to both human and animal health, to plant health, or to animal plant products. The current list of these agents is available directly from the Centers for Disease Control and Prevention web site: http://www.cdc.gov/od/sap/docs/salist.pdf
The laboratory practice, technique, safety equipment and facility design should be in accordance with the current U.S. Department of Health & Human Services Centers for Disease Control and Prevention and National Institutes of Health Biosafety in Microbiological and Biomedical Laboratories guidance (BMBL).
6.13 – Importation/Exportation of Infectious Agents
Importation of infectious materials, etiologic agents and vectors that may contain them is governed by federal regulation. An import permit is required for any infectious agent known to cause disease in humans, animals and plants. This includes but is not limited to bacteria, viruses, rickettsia, parasites, yeasts and molds. In some instances, an agent that is suspected of causing human disease also requires a permit.
Any person wishing to offer an infectious agent for shipment (export or import) must first receive training to do so from Environmental Health and Radiation Safety.
All records must be retained for three (3) years from the date of importation or exportation.
