BT605 Final Term Past Paper 2017

BT605 Final term Past Papers 2017 solved

1. What are the precautions made in BSL2 as compared to BSL1. 2

1. The major difference in BSL1 and BSL 2 workers which are working in BSL 2 in lab must have training for handling infectious material.
2. Special practices and equipment also required.
3. We restrict movement of people in the lab having BSL-2.
4. Then special bio containment required for this lab especially biosafety cabinet.

2.Physical Security elements? 3

Topic no 129 Physical security Elements

It not only deals with protection of people but Also deals with hardware network

programmes as well as protection of data .Now physical elements are of three types these are abstacals notification and recovery stage.Obstakles placed in the way of attackers.Survillence and notification systems.Methods to recover quikly from disasters.

3.Equipment used in BSL3, write 5 points 5

Equipment:now here special equipments are required for example apart from personal equipment glass eye feel any shoe cover we also require special vaccume line msut be protected with HEPA

How risk can be reduced through risk management? 5 Write note on special practice in BSL2. 10 Discuss malicious risk groups and Its Types? 10 BT605

4,Biosecurity?3

US Legistlation:Biosecurity Bill 2014 and supported lagistlation were passed by government Now they become biosecurity act 2015. We apply this act in every field related to agriculture, Related to pharmaustical. Agriculture biosecurity department has made cooperation collaboration with 400 organisations. Biosecurity act of US consist of 630 pages.

Future aspect of this biosecurity act 2015:

Biosecurity act support biosecurity sytem in any age. Regardless of the advances in technology in scientific field like biotechnology. Scientific advances and advises help to make right decision. Objectives:Was to create a modern and responsive legislation framework. Improves the underpinning process so create the robust biosecurity system that benefits everyone. Now this robust system prevent entry and establishment of invasive and exotic pests which are lethal because these species not only harmful for the environment but also related to the safety of humans also depends upon economy.

Q5. BSL3?

Topic 85

BSL-3:It is applicable to diagnostic lab clinical research areas even production and teaching facility’s, BSL3 include those agents that cause fetal disease and potentially hazardous disease in the human being because they appear in the environment in the form of aerosols and human being can inhale them as result enter in to the body through inhalation rout. microbiological practices should be performed in the biosafety cabnint . Equipment:now here special equipment’s are required for example apart from personal equipment galss eye shield and shoe cover we also require special vacuum line must be protected with HEPA

Topic no 86

6.BSL-4:

This is the highest containment level it include those agents that are dangerous exotic because they have ability to appear in the environment or contaminate environment in the form of aerosol .Aerosols are easily inhale by the workers who are working in the lab and can be easily infected by the infectious agents. These are dangerous because cause lethal disease inhumans no special vaccines are available no special treatment no specil precautionary measures can be taken. Here we have to take special precautionary measures for workers who are working in lab in order to prevent the formation o aerosol as much as possible now there is unknown risk for transmission. We divided BSL-4 in two types

1. A cabinet laboratory: Manipulation of agent in BSC.be can manipulate culture infectious material in a biosafety cabinet. Now biosafety cabinet that is satisfied and used according to the manufacturer detal they have double doors material that contain infectious agent fisrt passes through autoclave for sterilization then disposed of biosafety cabinet. Now in autocalve sterilization occurs 21 degrrecentgrade for 15 to 20 mintues pressur 15 poundes. Biosafty cabinet must be designed if infectous material not sterllized in autoclave it must be removed carefully from biosafty cabnet. Never put sharp things in BSC.It is better to avide such material. Now apart from HEPA filaters which are used in filtartion that intake airand exote air gas and vapor decontaminaton unit in BSC.Now the worker who are using biosaftey cabnet must wear glass eye shields then shoes cover once they enter into the lab they have followed all those personal equipments which are required for the lab bsl4. It is responsibility of lab manager to look at repair and maintainance of

BSC. 2ND TYPE:A suit laboratory: Where personnel must wear posisitive pressure air protective suit.BSC used for all microbiological procedures and decontamination od gloves and apparatuses during lab operations.

Q7. Risk management?

Topic No 151 Risk assessment or Risk management

Article 15 Annex 3 of Cartagena protocol set forth in national biosaftey guidelines .National Biosaftey committee will monitor all activities that are performed by researchers whether they
