Online Biosafety Courses
Assignment Earl Clarence Coniconde,
Section B
1. Introduction to Biosafety
a. In the late 19th century, German microbiologist Robert Koch and his research
team was able to culture and identify several bacterial microorganisms, which is a
significant contribution in the development of laboratory procedures involving
infectious microbial diseases.
b. With the help of technological advancements in biosafety equipment,
recent laboratory standard practices have immensely decreased the incidence rate
of laboratory-associated infections and exposure to pathogens among lab
workers.
c. Biological material in the laboratory means any organic material including both
harmful and non-harmful microorganisms, their biological or chemical compositions,
and other related by-products.
d. Over the span of several decades, several laboratory techniques such as inhaling
microbial cultures and mouth pipetting, poses increased biohazard health risks among
laboratory personnel; however, these practices are now prohibited and strongly
discouraged in today’s laboratory standards and policies.
e. In order to immediately recognize, isolate and contain biohazardous material
from other non-hazardous materials, a universal biohazard symbol was created and
formally adopted by the CDC and other international health organizations in 1967.
f. Lab workers have a comprehensive biosafety roles and responsibilities in
ensuring proper handling infectious microbes and products; similarly, shared
biosafety accountability is also in the scope of responsibility of license holders and
biosafety office committee.
g. Risk refers to the probable outcome that may have a detrimental effect to a
person, place or circumstance especially in the laboratory premises. Anticipated
possible exposure to a risk and its negative effects determines the degree of risk.
Questions:
• It is a type of risk assessment that reinforces the biosafety principles as a
whole and it also includes more than one containment zones in a workplace setting.
a) Overarching risk assessment
b) Local risk assessment
c) Pathogen risk assessment
d) None

, ANSWER: a
• This risk group of microbes have a high personal risk, high community risk and
may cause serious illness in either human or animal, often results in immediate death.
a) Lactobacillus acidophilus
b) Saccharomyces cerevisiae
c) Staphylococcus aureus
d) Ebola virus
ANSWER: d
2. Laboratory Acquired Infections
a. Laboratory acquired infection is defined as any infection obtained through
direct or indirect contact to pathogenic microbes or related infectious materials usually
in a laboratory setup or clinical facility.
b. Although first written records of LAIs can be traced all the way back to late 19th
century time period, there are still several unreported cases of LAIs happening
everyday, and many laboratory staff are at serious health risk.
c. Even if there is no exact reported cause or incidence in the written
documents, pipette aspiration, needle and syringe use, and exposure to spillage are
some of the most common identified causes of LAIs.
d. No matter how small or insignificant, it is important to immediately document
and report all laboratory incidents associated with exposure to LAIs in order to help
avoid information errors and maintain the veracity of recorded details.
e. It is noted that interventions such as raising awareness about LAIs and providing
biosafety trainings among lab workers greatly help minimize future recurrence of LAIs
and other related infections.
f. Proper use of personal protective equipment (PPEs), available biocontainment
gadgets and strong adherence to laboratory standards and practices reduces great
amount of health risks associated with laboratory hazards.
g. Aerosols are composed of gaseous solid particles or liquid droplets in a
suspension. Inhaling aerosols which may contain microorganisms or other airborne
particles play a major health threat among workers in the laboratory.
Questions
• Which of the following is NOT a route of exposure or source of lab accidents?
