Work-related lung diseases are lung problems caused by long-term exposure to particles and materials in certain work environments. They include conditions like asbestosis, black lung disease, silicosis, and asthma caused by repeated inhalation of dusts, fibers, gases, and fumes from sources like factories, mines, and agriculture. Symptoms include coughing and breathing difficulties. Diagnosis involves medical history, exams, and tests. While lung scarring cannot be reversed, treatment focuses on preventing further exposure and managing symptoms. Workplace safety measures are important for prevention.

2. What are work-related lung diseases?
Work-related lung diseases are lung problems
that are caused by certain work environments.
They are caused by breathing materials into the
lungs. These lung diseases may have lasting
effects, even after the exposure ends.
Particles in the air from many sources
cause these lung problems. These sources
include factories, smokestacks, exhaust,
fires, mining, construction, and agriculture.

3. ● Asbestosis. This is caused when a
person breathes in tiny asbestos
fibers. Over time, this leads to lung
scarring and stiffening of the lungs
● Coal worker's pneumoconiosis or
black lung disease. This is caused by
breathing coal dust. It causes lung
inflammation and scarring.
● Silicosis. This condition is caused by breathing in airborne
crystalline silica. This is a dust found in the air of mines,
foundries, and blasting operations. It is also found in the air
of stone, clay, and glass manufacturing facilities. It causes
lung scarring. It can also increase the risk for other lung
diseases.

4. ● Byssinosis or brown lung
disease. This is caused by
breathing in dust from hemp,
flax, and cotton processing.
It affects textile workers,
especially those who work
with unprocessed cotton.
● Byssinosis or brown lung
disease. This is caused by
breathing in dust from
hemp, flax, and cotton
processing. It affects
textile workers, especially
those who work with
unprocessed cotton.
● Work-related asthma. This is
caused by breathing in dusts,
gases, fumes, and vapors. It
causes asthma symptoms such
as a chronic cough and
wheezing. This condition can be
reversed if found early. You're at
higher risk of getting this illness
if you work in certain
environments. These include
manufacturing and processing
operations, farming, animal care,
food processing, cotton and
textile industries, and refining

5. CAUSES
What causes work-related lung diseases?
Certain types of jobs put you at greater risk for
this than others. For instance, working in a car
garage or textile factory can expose you to
unsafe chemicals, dusts, and fibers. There are
also genetic reasons that are not well-
understood.
Most work-related lung diseases are caused by
repeated, long-term exposure. But even one
severe exposure to an unsafe agent can damage
the lungs.
Smoking can make any work-related lung
diseases

6. SYMPTOMS
● What are the symptoms of work-
related lung diseases?
● Each person's symptoms may
vary. Common symptoms of
lung diseases include:
● Coughing
● Shortness of breath, which often
gets worse with activity
● Chest pain
● Chest tightness
● Abnormal breathing patterns
● Wheezing
● Scratchy, dry, or sore throat

7. • How are work-related lung diseases diagnosed?
• The first step is for a healthcare provider to ask about a
person's symptoms, job, and what kinds of materials they are
exposed to at work.
• Tests that may be needed to figure out the type and severity of
the lung disease include:
• Chest X-ray
• A test that takes pictures of internal tissues, bones, and
organs.
• Pulmonary function tests
• These tests help measure how well the lungs move air in and
out. The tests are often done with special machines that you
breathe into.
DAIGNOSIS

8. ● Bronchoscopy
This test uses a flexible tube called a
bronchoscope to view the main airways of the
lungs (the bronchi). Bronchoscopy helps to
diagnose lung problems, look for blockages, take
out tissue or fluid samples, or remove a foreign
body. This test may include:
● Biopsy. This test takes out a small piece of
tissue, some cells, or fluid from the lung.
This is then checked under a microscope.
● Bronchoalveolar lavage. This test
removes cells from the lower respiratory
tract. This is done to help find inflammation
and rule out certain causes.

9. ● Blood gas
This test measures the amount of carbon
dioxide and oxygen in the blood. Other
blood tests may be used to look for possible
infections and other problems.
● CT scan
This is an imaging test that uses X-rays and
a computer to make detailed images of the
body. A CT scan shows details of the bones,
muscles, fat, and organs. CT scans are
more detailed than regular X-rays. They can
be used to diagnose lung diseases, watch
disease progression, and check the
response to treatment.

10. TREATMENTS
How are work-related lung diseases
treated?
There is no cure for most work-related lung
diseases other than lung transplant.
Treatments are aimed at:
• Preventing further exposure
• Preventing more lung scarring
• Managing symptoms
• Helping you stay active and healthy
• Treatment depends on the type of lung
disease. There is no way to fix lung
scarring that has already happened.

11. PREVENTION
Can work-related lung diseases be prevented?
The best prevention is to avoid being exposed to
dangerous materials. It's important to use
protective equipment when working with materials
that can cause lung disease. This can include
wearing facemasks or respirators. In addition,
always follow workplace safety steps. It's also
important not to smoke. And to follow advice for
lung testing (such as spirometry) to measure your
lung function.
An occupational health expert can check a
workplace for risks for work-related lung diseases.
Employers can also protect workers by following
safety and health regulations.

12. ● Work-related lung diseases are lung problems
that are made worse in certain work
environments.
● They are caused by long-term exposure to
certain materials that are breathed into the
lungs.
● Particles in the air from many sources cause
these lung problems. These sources include
factories, smokestacks, exhaust, fires, mining,
construction, and agriculture.
● Common symptoms include breathing
problems such as coughing and shortness of
breath.
● There is no way to fix or regrow damaged
lung tissue. The goal of treatment is to stop
further exposure, prevent worsening of the
disease, manage symptoms, and help you
stay active and healthy.
● Workplace protection is key to preventing and
managing these diseases.
