GUIDELINES ON LABORATORY SAFETY
These guidelines cover the hazardous nature of laboratories and laboratory work and direct the reader to a wide range of information available on laboratory safety.
Due to the diverse nature of laboratory work specific laboratory safety information is not provided here. Instead reference should be made to local or departmental laboratory safety manuals and standards operating procedures (SOPs) that should be developed and made available in each laboratory area to cover the wide range of risks posed by local laboratory operations and practices.
A reference list of relevant Standards, Codes of Practice, Guidance Notes and legislative documents is provided to assist staff to achieve laboratory safety compliance and management of risks associated with laboratory work, to ensure the health, safety and well-being of all personnel working in or accessing laboratories.

These guidelines are applicable to all University staff and students who work in laboratories and associated areas. They are also applicable to contractors and other University affiliates who visit or access University laboratories and associated areas. Responsibilities for managing health and safety in laboratories is also included.
A laboratory is a place, building or part of a building used for scientific and related work that may be hazardous. The work conducted in a laboratory may include teaching or learning, research, clinical or diagnostic testing and analysis. A laboratory may have associated areas including preparation, instrumentation, decontamination, wash-up and storage rooms, or a workshop in an engineering area (eg mechanical, electrical, aeronautical and civil engineering).
Laboratories are commonly used for scientific disciplines ranging from biology, chemistry, physics, botany and zoology to medicine, psychology, dentistry, engineering, agriculture and veterinary science.
Laboratory design and construction plays an essential and critical role in ensuring that laboratories and associated areas are safe places to work and visit.
Safe design principles are fundamental to laboratory design and are detailed in the WorkCover publication Safe Design of Buildings and Structures. These principles consider the safety of those who construct, maintain, clean, repair and demolish a laboratory building or structure, as well as those who work in or visit the laboratory. Laboratory personnel, project managers, design managers, architects, engineers, and others involved in the laboratory design and construction process, have an important role to play in identifying health and safety risks that could arise throughout the life cycle of the laboratory building or structure and where practicable, eliminating or reducing risks during the design and construction phase.
Management of health and safety in laboratories is therefore an ongoing responsibility shared by a number of people who control the design, construction, use and maintenance of these areas.
General requirements to be considered when planning for the construction of a new laboratory or refurbishment of an existing laboratory are detailed in AS/NZS 2982 - Laboratory design and construction – Sections 1 to 7. Laboratories that are to be used for biological or radiological work have additional requirements as detailed in Sections 8 and 9 of this Standard. AS/NZS 2982 is to be used in conjunction with the Building Code of Australia (BCA) and NSW Work Health and Safety (WHS) legislation and other relevant Australian Standards.
Microbiological laboratories have specific containment requirements in addition to those specified in AS/NZS 2982. Refer to AS/NZS 2243.3 - Safety in laboratories Part 3: Microbiological safety and containment for details.
Laboratories are considered to be high risk environments when compared to other areas in the University (e.g. offices, tutorial rooms, lecture theatres etc). As a result, entry to any laboratory is to be restricted to individuals who are authorised by the laboratory supervisor or laboratory manager, to enter. The Supervisor shall ensure that any person given authority to enter receives appropriate:
(a) information regarding hazards and related risks that are present;
(b) safety measures to be adopted (eg local rules, SOPs, suitable protective clothing and equipment etc), and
Children are not permitted in laboratories, workshops or associated areas (refer to Children in Univeristy Workplaces and Premises Policy).
Defined simply, a hazard is anything that may cause injury, harm or damage. The hazards encountered in a laboratory are many and varied and may result in short term or long term health effects if individuals are exposed to these hazards. When planning any work in a laboratory the risk of exposure to laboratory hazards is an important consideration during the risk assessment and risk management process.
Laboratory hazards fall generally into one of five categories:
- Biological - eg pathogenic microorganisms, animals, biological tissues, blood and other body fluids (human and animal)
- Chemical - eg corrosive, flammable, toxic
- Physical - eg noise, radiation, manual handling
- Electrical/Mechanical - eg high voltage apparatus, machinery with moving parts
- Psychological - eg emotional stress, workplace bullying
Laboratory safety rules and safe work practices or standard operating procedures (SOPs) should be established by Faculties, Schools and Disciplines to meet specific operational needs and to reduce the risks associated with laboratory hazards.
As a condition of entry to a laboratory, all individuals must complete a laboratory safety induction and receive specific training in local safety rules and laboratory procedures relating to their work (including relevant SOPs).
Individuals are required to comply with laboratory safety rules and procedures at all times whilst in the laboratory. Individuals who act contrary to the rules and procedures should be excluded from the laboratory.
Responsibility for safety and compliance with laboratory safety rules and procedures rests primarily with the management of the laboratory. Work Health and Safety (WHS) Advisers, Safety Officers and Health and Safety Representatives (HSR) may also provide advice and feedback on the effectiveness of risk control measures outlined in local laboratory safety rules, manuals or SOPs for work being carried out within a laboratory. (Refer to the OHS Policy).
Heads of Schools, Disciplines and Centres: are answerable through their Dean/Head to the Vice-Chancellor and the Senate for the administration of their departments in accordance with legislative requirements and University policies. This includes responsibility for the health, safety and wellbeing of staff, students, contactors and affiliates who work in or access laboratories. They must also ensure that WHS risks relating to all activities undertaken in laboratories under their control are properly identified, assessed and controlled.
Supervisors/Lab Managers: have a particular responsibility to their Head of School, Department, or Centre for ensuring that the work for which they are responsible is carried out in a manner that safeguards the health, safety and wellbeing of staff, students and visitors in their charge. They must also ensure that all personnel who access laboratories have received the appropriate laboratory safety induction and training to enable them to undertake their work safely, and that documented records of this training is kept for at least five years.
Staff/Students/Affiliates: required to undertake work in laboratories are to comply with local laboratory safety information, rules, manuals and SOPs. Failure to comply may result in disciplinary action being taken by the University.
Staff and students must take personal responsibility for ensuring their own safety and the safety of others by:
- taking the necessary action(s) to eliminate or minimise the risks of laboratory hazards over which they have control;
- complying with safety instructions, policies and procedures, including local/departmental safety rules, manuals and SOPs;
- completing the appropriate laboratory safety induction and training to enable them to undertake their work safely, and ensure that this training is documented and records are kept by the supervisor/laboratory manager;
- making proper use of all safety devices and appropriate personal protective clothing and equipment;
- complying with the instructions given by emergency response personnel such as emergency wardens and first aid officers;
- not wilfully placing at risk the health and safety of any other person;
- seeking information or advice where necessary before carrying out new or unfamiliar work;
- maintaining dress standards appropriate for the work being done i.e. appropriate personal protective clothing, footwear and equipment must be worn and used at all times;
- only consuming or storing food and drink in designated areas outside the laboratory;
- being familiar with emergency and evacuation procedures and the location and use of emergency equipment (only if appropriately trained);
- reporting all incidents, injuries, hazards and 'near miss' incidents to their supervisor and submitting a report on the 'Riskware' reporting system.
There are many different types of laboratories and a great number and variety of different hazards which may be found in them. Consequently, there is a large volume of information available which addresses health and safety in laboratories. This information may be derived from the University's A-Z of WHS Information, regulatory information and literature, experienced personnel in the University or external experts.

(d) Material Safety Data Sheets (MSDS)
MSDS are used internationally to provide the information required to allow the safe handling of hazardous substances at work. The MSDS describes:
- the substance - i.e. its identity, physical properties, chemical properties and uses;
- health hazard information;
- precautions for use;
- appropriate personal protective clothing and equipment; and
- safe handling information (including first aid, dealing with spills and emergencies etc)
Staff, students and other laboratory personnel shall be provided with ready access to MSDS for each chemical they use in their workplace/laboratory (refer to ChemAlert - chemical information database). Laboratory chemicals should only be purchased from suppliers who will provide an appropriate MSDS, that is less than five years old, for each chemical supplied.
(e) University Policy and Information
The University has a Policy Register that includes Health and Safety policies and information on a range of work health and safety requirements, many of which are relevant to those working in laboratories (refer to A-Z of WHS Information).
(f) Other Texts on Laboratory Safety
There are many texts which provide information on various aspects of laboratory safety - subject areas range from dangerous properties of chemicals, toxicology and waste disposal to specific texts on laboratory safety. These texts are available from various book suppliers with a range available for perusal in the WHS library (contact the WHS Services on x14335 for assistance).
Information on laboratory safety may also be acquired from other personnel (within or outside the University) who have relevant experience and knowledge.
Any health and safety concerns of staff or students should be discussed initially with the local Supervisor eg., academic staff member, laboratory manager or senior technical officer in charge of the laboratory.
Most departments have a Safety Officer who acts as a local source of information on WHS matters and may be approached for advice.
Other Safety Officers
Many departments also have a local Radiation Safety Officer or Biosafety Officer who has specialist knowledge in these areas. They may be approached for information on radiation safety or biological safety.
Local WHS Represetnatives can be contacted for advice and assistance with WHS issues arising in their work area.
Work Health and Safety Services (WHSS)
WHSS has WHS Advisers, including a Radiation Safety and Biological Safety Adviser that can be contacted for further information or advice on laboratory safety matters.
There are many organisations and individuals external to the University who may provide information on particular safety issues eg, the NSW WorkCover Authority, Safe Work Australia, ANSTO, CSIRO, Department of Health and Ageing, specialist consultants etc.
