What is biological hazard. Physical Hazards in the Laboratory.
They include viruses bacteria and fungi and their metabolites as well.
What are the possible hazards in a biological laboratory and their sources. The term biohazard refers to any biological materials microorganisms plants animals or their byproducts that pose a threat to the health of living organisms. The following list of Physical Hazards in the laboratory is included in Prudent Practices 4 Evaluating Hazards and Assessing Risks in. Introduction to biological agents Biological agents are living organisms or products of living organisms.
Biological hazards include potential exposures to allergens infectious zoonotics animal diseases transmissible to humans and experimental agents such as viral vectors. Every biological laboratory setting regardless of economic or organizational capability. See Part 3 of this Guide for details and examples of the hazard categorisation scheme for biological agents.
Finally sources of further information are presented at the end of the e-fact. Laboratory workers who are threatened by human pathogens and among agricultural workers who are at risk from dust-borne biological allergens and toxins and by parasitic worms in warm climates. Pathogens must be handled with great care in order to avoid infection of staff the general public and animals outside the laboratory.
Sources of biological hazards may include bacteria viruses insects plants birds animals and humans. Biological hazards refer to organisms or organic matters produced by these organisms that are harmful to human health. The use of bacteria viruses blood tissue andor bodily fluids in the lab can lead to potential biological hazards.
Because risk is a function of likelihood and consequences and a risk assessment is specific to a laboratorys hazards threats and work practices the results of an assessment will undoubtedly vary dramatically between laboratory settings. Microbiological hazards are particularly insidious because of the microscopic size of the organism. In cases where substances with significant or unusual potential physical hazards are involved consult more detailed references such as Urben 2007 and other sources discussed in section 4B of this chapter.
Allergens ubiquitous in animal research facilities are one of the most important. Physical hazards include foreign objects in food that can cause harm when eaten such as glass or metal fragments. Types of biological hazards.
These materials can all carry disease or hazardous allergens which could put the lab team at risk. The safest procedure is to regard all micro-organisms as potential pathogens and treat them accordingly. Worldwide around 320000 workers die each year from communicable diseases caused by work-related exposure to biological hazards European Agency for Safety and Health at Work.
Electricity has long been recognized as hazardous. Physical Hazards in the Laboratory. Consult an up-to-date laboratory chemical safety summary material safety data sheet or NIOSH Pocket Guide to Chemical Hazards HHSCDCNIOSH 2007.
Potential biohazards can be found anywhere at your job in your doctors office in your childrens classrooms and should be handled with extreme caution. There is growing evidence that biohazards are also important. These sources can cause a variety of health effects ranging from skin irritation and allergies to infections eg tuberculosis AIDS cancer and so on.
Laboratory health and safety risks arise from both the chemical and physical hazards of your work and the work being done by others in the lab. Ideally all of the electrical circuits in a science laboratory should include ground fault circuit interrupters GFCIs which are designed to protect people from electrical hazards. Chemical hazards include compounds that can cause illness or injury due to immediate or long-term exposure.
Biological hazards include harmful bacteria viruses or parasites eg salmonella hepatitis A and trichinella. Hazard categories and containment For any work entailing possible exposure to biological agents correct identification of the hazard category of an agent is an essential element of the risk assessment. It can cause electric shock electrocution burns fires and even explosions.
