Laboratory work should be carried out with a minimum of risk to the health of the staff working in laboratory. This requires careful consideration of the risks involved in a particular procedure, followed by appropriate measures to minimise the risk of human disease. This concerned exclusively with risks from infectious agents, but physical and chemical injuries in microbiology laboratories must also be prevented. Risks from infection are reduced by good laboratory techniques and secured facilities which aid in the containment of pathogens. It is important to understand that containment of pathogens can be used for preventing disease in humans and animals. Often the same methods of containment are used for both preventing laboratory-acquired infection in humans and for preventing escape of pathogens that could cause an outbreak of animal disease. Although the methods, techniques and facilities required may be the same, the list of pathogens and categorization into levels of risk will differ depending on whether it is human or animal disease control that is the primary objective. Existing national and international reference laboratories have considerable experience in the operation of safe working practices and provision of appropriate facilities. When new laboratories are being established, it would be prudent to seek advice from the competent authorities at established institutes and it is important to comply with legislative requirements.
