Answer 1

ANSWER 13 :-

1. The BSL-1 also termed as the biosafety level 1 deals with the basic procedures for handling the infectious diseases which can be easily controlled under basic sanitary measures. This includes use of lab coats and other protective measures that are essentially required for lab associated experiments and culturing. There is not much risk associated or in other terms, it can be stated to have low risk and hence eyewash station is not needed. So, option 'A' is not appropriate.
2. The BSL-2 basically deals with the infectious agents that holds an intermediate risk of spreading and hence from this stage onwards intensive care is taken regarding handling of potent toxins and microbial cultures. The eyewash station provides a regulated flow of water which is not strenous to the eyes and blocks any type of infection due to maintainance of proper hygienic conditions. It is used to rinse both the eyes in case of emergency situations and the BSL-2 deals with certain toxins, chemicals and microbial agents that may come into contact with eyes and hence includes the eyewash station. So, option 'B' is the most appropriate option.
3. BSL-3 deals with agents (microbial) that can easily get transmitted through the medium of air and hence carries a higher risk and hence chambers needs to be properly designed with respect to flow of air, enclosure, and equipments such as autoclaves and other which are associated with sterilization and decontamination of potential agents and hence the safety regulation needs to be improved as compared to the above mentioned states. Although, there is no requirement of an eyewash station and hence, the option 'C' is not appropriate.
4. BSL-4 includes handling of the microbial agents that may be lethal and have the potential to pass through many routes in order to spread. They may be generated in the form of minor films or contagious particles that may spread due to improper handling or other associated practices. The chambers are properly sealed as the source exhibit a potential life threatening risk and are provided with facilities to easily decontaminate the surrounding. Due to maximum risk associated, basic requirements like eyewash stations are avoided although shower stations are present to ensure proper hygiene. So, option 'D' is not appropriate.

Option 'B' is the most appropriate answer.
