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.

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

valuable information in the area of

occupational medicine I value any
