Dr. Ozzy, an Australian occupational medicine specialist, introduces the topic of biological hazards in the workplace. These hazards, which include harmful organisms or their byproducts, can cause infections, allergies, and poisonings. Infections can occur through direct contact, indirect contact via fomites, foodborne or waterborne transmission, droplet and airborne contamination, and vector-borne diseases. Examples include viruses, bacteria, fungi, and zoonotic diseases. Allergies can result from contact with animals, plants, or their products. Poisonings can occur through contact with certain plants, animals, or marine life. Occupational factors, such as the type of work and the work environment, play a significant role in determining the risk of exposure to these hazards.
🛡️ Managing Biological Hazards in the Workplace
To manage biological hazards, Dr. Ozzy discusses the hierarchy of controls, emphasizing the importance of eliminating hazards when possible. This includes removing sources, using pesticides, and employing sterilization and disinfection techniques. Engineering controls such as isolation facilities, ventilation systems, and specialized storage are also crucial. Administrative controls involve policy reviews, immunization programs, health monitoring, and training. Personal protective equipment (PPE) is necessary for workers who may come into contact with biological hazards. The video concludes with a call for tailored controls based on specific hazards and a promise of more detailed examples in future videos.

Highlights
Biological hazards are defined as organisms or organic matter produced by these organisms that are harmful to human health.
Biological hazards can cause three broad health effects: infection, allergy, and poisoning.
Infections can be transmitted directly or indirectly, including through contact with blood or body secretions.
Indirect transmission can occur through contact with surfaces where infectious agents can survive for extended periods.
Foodborne and waterborne toxins can lead to infections due to poor food handling or contaminated water sources.
Droplet and airborne contamination, such as from coughing or sneezing, can transmit infections over distances.
Environmental factors like soil or water can be sources of infections, including Legionella from water-based cooling towers.
Vector-borne diseases involve organisms carrying disease-causing microorganisms, allowing transfer between hosts.
Susceptibility to infections depends on factors like geographical location, vector and host characteristics, and protective measures.
Allergies can result from contact with animals, plants, or their products, leading to irritant contact dermatitis or allergic reactions.
Poisonings can occur from contact with certain plant species, animal bites, or direct skin contact with harmful creatures like jellyfish.
Occupational factors play a role in the risk of exposure to biological hazards, with some jobs having a higher risk due to the nature of the work.
Outdoor workers, those in agriculture, forestry, or fishing, and laboratory workers are at increased risk of exposure to biological hazards.
Geographical location and environmental factors can influence the prevalence of vector-borne diseases like malaria.
Socioeconomic and cultural practices can affect susceptibility to certain infections and the risk of zoonotic infections.
Indoor workplaces, especially enclosed spaces with central air conditioning, can be potential sources of biological hazards.
The hierarchy of controls is used to manage biological hazards in the workplace, tailored to the specific worker, occupation, and environment.
Elimination of hazards, engineering controls, administrative controls, and personal protective equipment are key strategies for managing biological hazards.
The video provides valuable information on occupational medicine and will explore specific examples of biological hazards in future videos.
Transcripts
get a everyone this is Ozzy op doc and
thank you for visiting my channel what's
up doc I'm a doctor from Australia and I
specialized in the field known as
occupational medicine hello everyone
today we'll be discussing one of the
more complex hazards in the workplace
biological hazards given the wide
breadth of this topic I'll be only
speaking generally and leave specific
examples for later videos so biological
hazards are defined as organisms or
organic matter produced by these
organisms that are harmful to human
health biological hazards can cause
three broad health effects on the body
namely infection allergy and poisoning
for infections this can be any organism
that is capable of causing disease
some examples include viruses bacteria
and fungi animals can also transmit
infections to humans known as ooh and
nurses and this can be either direct or
indirect
a transmission of infections this can be
direct and this is where physical
contact with the infected person or
infective agent can lead to direct
transmission it can also result from the
exposure to biological material such as
blood or body secretions there can be
indirect transmission through surface
contact so some infectious agents can
survive on surfaces for extended period
of time and some inanimate objects or
materials can act as mechanisms for
transfer known as fomites for example it
can be common objects such as door
handles or kitchen countertops
it can also be food borne or waterborne
toxins infections can also be
potentially contracted via contaminated
food or water sources this can be due to
poor food handling poor hygiene or
drinking contaminated water droplet and
airborne contamination mucus secretions
emitted from coughing or sneezing can
create droplets or aerosol infections
that have the potential to transmit over
certain distances for example influenza
droplets can come from the environment
such as soil or water and cause
infections environmental examples
include the transmission of Legionella
from aerosolized
droplets from water-based cooling towers
vector borne disease vectors are
organisms which can carry on them
disease-causing microorganisms and
allowed their transfer from one host to
another vectors are often fairly mobile
allowing the distance of potential
disease transmission to be high
susceptibility and depend on a number of
factors including geographical location
vector and host characteristics as well
as protective measures in place examples
can include malaria carrying mosquitoes
for allergies animals and plants and
their respective products can be
potential allergy closing agents this
can come either via direct inflammation
of the skin known as irritant contact
dermatitis contact with particular
agents can also lead to an allergic
reaction so that with subsequent contact
this can lead to development of a skin
initially known as allergic contact
dermatitis the final way that biological
hazards can cause health effects on the
body is poisonings contact with certain
plant species of plant materials can
cause poisonings contact with certain
animals particularly being in by snakes
or spiders or direct skin contact with
jellyfish can cause harmful effects
occupational factors can also be
important in determining the risk of
coming into contact with biological
hazards namely the type of occupation as
well as the location and environment of
the work with types of occupations some
biological has its intrinsic to is a
specific occupation outdoor workers can
be exposed to a wide range of bio
hazards those they work in close contact
with animals or animal products such as
those in agriculture forestry or fishing
industries are more at risk of zoonotic
or vector related diseases arbitral
workers can also be at risk to that the
close contact with animal products
health scan laboratory workers are also
increased risks through the exposure to
human blood and bodily fluids working in
roles which involved hand and liquid
waste rubbish collection and disposal
can also be high-risk the location and
environment can also be important vector
borne diseases can also be more
prevalent depending on the geographical
location such as malaria which is
endemic throughout most of the tropics
socioeconomic factors as well as certain
cultural practices can also lead to
susceptibility of certain infections for
example when markets can lead to the
increase risk of zoonotic infections as
well as food and water contamination
indoor workplaces can also be potential
sources of biological hazards
particularly in enclosed spaces areas
with central air conditioning or areas
of public objects or spaces in order to
manage biological hazards again we use
the hierarchy of controls the complexity
of biological hazards in the workplace
means that the development of controls
need to be tailored to the worker the
specific occupation in the workplace
with elimination if possible elimination
of the hazards should be the highest
priority
this could mean eliminating the source
such as water reservoirs for Legionella
lemon aiding the agent of vector by the
use of pesticides or through the use of
sterilization and disinfection
techniques such as heat pressure and the
use of chemicals engineering controls
having specialized isolation facilities
for those working in the laboratory
setting having ventilation systems such
as negative pressure and safety cabinets
has specialized storage and transport of
biological agents automating equipment
having adequate waste disposal such as
sharps containers and biological hazard
bags administrative controls review of
policies and procedures particularly at
those involving infection control
immunization programs for the workers
regular health monitoring of workers
training on safe handling of biological
materials having adequate labeling and
warning signs as well as regular review
and maintenance of ventilation and
airconditioning
finally with PPE having the adequate
gloves protective clothing eye and face
protection and Rasputia protection in
summary biological hazards can have a
number of health effects on the body
namely infection allergy and poisoning
occupational factors can also be
important in determining the risk of
exposure namely the type of work as well
as the location and environment finally
it's important to tailor your controls
to the specific biological hazard that a
worker will be exposed to in their
occupation I'll be leaving a few
references in the video description if
you wish to explore this topic further I
will also go into more specific examples
of biological hazards in subsequent
videos thank you for watching this video
I hope that I provided you with some
valuable information in the area of
occupational medicine I value any
feedback therefore please feel free to
leave a comment on any of my videos as
well as a like if you enjoyed it if you
