Risk management associated in handling of microbial pathogens as well as other lab animals is very critical and important. Today in biotechnology industries and pharmaceutical field, large number of microbial pathogens (Bio-Hazard) is being used and handled. Therefore there is a need to understand the importance of bio-hazards and to acquire its complete knowledge, its precautions, and what immediate actions are required in case of its contact during working or during research studies.
Biohazards are biological substances that may pose threat to life or living organisms especially humans. This may include but not limited to waste generated during medical operations, medical research work, or may be living microorganism or their waste. Even after the killing of such pathogens, there is a chance of reaction or immunological triggers in human bodies which is due to so called pyrogens. Pyrogens increases the body temperature and may lead to diseases or disorders.

The sign of bio hazard is U+2623 & symbol (☣). Proper training is required with evaluation of training for new members or students handling bio-hazards. Proper facility is also required with ventilations, classified rooms, safety hoods, personal preventive equipments etc. This helps us to safeguard ourselves from such bio hazards.
Whenever any unexpected contacts with bio hazards occurs, one has to immediately take medical help or treatment as recommended by doctors. Many a times these pathogens in lab or research area are attenuated that is they are half killed and does not cause diseases. On these bases, they are given the hazard level numbers which further depends upon the severity of it.
