Biosafety and Exposure Control Training

Questions and Answers

What are Standard Precautions and their significance in biosafety protocols?

Standard Precautions are a set of practices designed to prevent the transmission of bloodborne pathogens by treating all blood and bodily fluids as potentially infectious, reducing the risk of exposure.

How does the use of PPE contribute to an effective Exposure Control Plan?

PPE, such as gloves, gowns, and face shields, protects employees from direct exposure to blood and other hazardous substances, thereby minimizing the risk of infection.

What immediate actions should be taken in the event of a blood exposure incident?

In case of exposure, the area should be flooded with water, wounds cleaned with antiseptic, and the incident reported to a supervisor while seeking medical attention.

Describe the role of engineering controls in biosafety protocols.

Engineering controls, such as biological safety cabinets and needle-free devices, are designed to eliminate or minimize exposure to hazardous substances by altering the environment or equipment used. Signup and view all the answers

What is the purpose of decontamination methods like sterilization and disinfection?

Decontamination methods like sterilization kill or inactivate all organisms, while disinfection reduces the microbial load on surfaces and equipment to prevent infection and contamination. Signup and view all the answers
