Definition:
Biosafety level present different kinds of biocontainment safety measures that are used to segregate dangerous biological microbes in the laboratories. There are different biosafty levels ranges from the biosafety level 1 (BSL-1) to biosafety level 4 (BSL-4) and these are categories as lowest to high respectively .
Introduction and Background
Biosafety implemented different set of controlled principles, activities, advance techniques and organized practices that are used to prevent unintended and involuntary exposure to hazardous agents i.e. pathogens and toxics along with their accidental discharge/release. The term Biosecurity’ means the protection provided to the valuable biological materials by considering proper control and accountability in order to eliminate and restrict their unauthorized release ,diversion along with their access and misuse .
There are many unique and distinctive problems which can be found in the animal rooms during animal activities. These animal rooms are better than microbiological laboratories because due the nature of activities of the animals they can present unique hazardous i.e. pathogens and toxic agents that were not found in standard microbiological laboratories. Hazardous agents through aerosols may be generated by the Animals which will include animal bite and scratch. At times there is some other toxic agents’ zoonotic agent which may be infected.
Animal Biosafety Levels
S.No Animal Biosafety Level (ABSL) Practices Primary barriers
(Safety Equipment) Facilities (Secondary Barriers)
1 It includes those organisms that are not dangerous and cause infectious diseases.
They have minimum potential hazards to the personnel and the environment. It involves standard microbiological practices No primary barrier
Needed eye and face protection mask, coats and gloves Bench/tool and sink required
2 It includes practices, advance procedures and equipments along with organized control with the facility of ABSL-1.
This level includes moderate potential hazard agents which cause moderate risk for personnel and low risk for community. It involves standard microbiological practices along with limited access
Universal biohazard warning sign
Instant precautions
Medical surveillance policies Primary barriers
Physical containment Devices used for manipulation of agents that cause infectious materials i.e. through air and splashes
Needed eye and face protection mask, coats and gloves
It require biosafety cabinet one
ABSL-1 and availability of autoclaves
3 Involves microbes which are infectious for both personnel and the environment.
They cause high risk for the personnel and moderate risk for the environment.
It includes practices, advance procedures and equipments along with organized control with the facility of ABSL-2.
They may cause potentially lethal disease via inhalation root of exposure. It includes ABSL-2 practices and controlled access
Decontamination of all contaminated waste
* Manage the purchase of equipment and ensure all appropriate accounts are funded, obligated and adjustments processed

Safety is a primary concern in the health care environment, but there are still many preventable errors that occur. In fact, a study from ProPublica in 2013 found that between 210,000 and 440,000 patients each year suffer preventable harm in the hospital (Allen, 2013). Safety in the healthcare environment is not only keeping the patient safe, but also the employee. If a nurse does not follow procedure, they could bring harm to themselves, the patient, or both. Although it seems like such a simple topic with a simple solution, there are several components to what safety really entails. Health care professionals must always be cautious to prevent any mishaps to their patients, especially when using machines or lifting objects, as it has a higher

Keeping patients safe is essential in today’s health care system, but patient safety events that violate that safety are increasing each year. It was only recently, that the focus on patient safety was reinforced by a report prepared by Institute of medicine (IOM) entitled ” To err is human, building a safer health system”(Wakefield & Iliffe,2002).This report found that approx-imately 44,000 to 98,000 deaths occur each year due to medical errors and that the majority was preventable. Deaths due to medical errors exceed deaths due to many other causes such as like HIV infections, breast cancer and even traffic accidents (Wakefield & Iliffe, 2002). After this IOM reports, President Clinton established quality interagency coordination task force with the help of government agencies. These government agencies are responsible for making health pol-icies regarding patient safety to which every HCO must follow (Schulman & Kim, 2000).
... in implementing control mechanisms that will help to measure the quality of products, at the time so that they are ready to evaluate the performance.
GM uses this system by containment, disposition, separation, and classification. Such a system guarantees that any outcome that does not comply with specified requirements is restricted from unintended use, restrained, and dispositioned by the administrators. Accompanied by this quality control is the verifying position where first-time quality and process capacity is advanced (Drew, 2011). Every team member is informed about any modifications in the production process and who and when to summon for assistance in the event of any quandary. Every team is also included in the problem solving to reach any improvement in goals.
Bacillus anthracis, is not only a dangerous bacteria that can cause a fatal disease, but is also one that can be manipulated to terrorist’ advantage to cause widespread and uncontrollable terror to entire societies. Qualitative analysis comes into play in consideration of the prevention of the spread of the disease, as proper and rapid identification of anthrax can drastically improve the prospects of halting contamination, as efficient diagnosis is directly correlated to prevention.
The purpose of this report is showing how to apply the control process in the
Most biological agents are dispersed in aerosol form. They can be sprayed from a small cylinder with compressed air, spread by guided missiles, dispersed as a powder from aircraft, or used in a cluster of bombs. The danger is the potential for these biological agents, if successful in infecting a population, can be spread quickly. The U.S. Navy tested the effectiveness of Biological weapons on a metropolis in November of 1950. They released harmless bacteria off the California coast, sufficient to contaminate 117 squar...
It’s true what everyone talks about safety – you are the key to your safety, when you do it safely you do it the right way and the best gift you can give to your family is to always stay safe. We have been taught by our parents and teachers to be cautious while doing a number of things. That’s very essential in our daily lives, because one needs to be extra cautious to prevent unavoidable accidents. However, mishaps do happen everywhere in the safest of places, no matter how careful we are in our actions. It is highly unpredictable, what’s going to happen the very next instant. There are numerous incidences we come across like simple trips, falls, cuts due to sharp objects, burns or sudden worsening of a person’s health condition, causing
Bioterrorism is an attack that involve by releasing bacteria, viruses and other harmful agents which can caused illness or death. Most of these agents can found in nature.
