Chemicals known to be found in diesel exhaust
Diesel exhaust contains 41 chemicals or more that the State of California has identified as toxic air
contaminants. The health risks of air toxins vary from pollutant to pollutant, but are all serious.
This is only a partial listing of the chemicals and compounds that may be found in the emissions from
any diesel engine. Most are known to be toxic and cause cancer. This list was compiled from several
sources and is believed to be accurate.

Health Impact of Diesel Particulate Matter:
Most particulate matter emitted by diesel engines is small enough to evade the body's defenses and
lodge deep in the lungs. Particulate matter air pollution is associated with increases in mortality,
especially in people older than 65 years old who have existing cardiopulmonary diseases and in infants
and children with developing lungs. It is also associated with health problems including aggravation of
asthma, especially in children, and other chronic lung diseases, impacts on lung function, and
increased susceptibility to infectious illnesses. Your severity of exposure will vary based on where
you live, commute and work. Here are some of the risks of exposure:
Short-Term Effects
-
Irritation of eyes, nose and throat.
-
Inflammation of lung tissue
-
Difficulty breathing
-
Asthma attacks
-
Coughing
-
Wheezing
-
Dizziness
-
Drowsiness
-
Nausea
-
Vomiting
-
Headache

-
Bronchitis
-
Persistent cough
-
Cancer
-
Hypertension
-
Heart disease
-
Stroke
-
Infections and blood disorders
-
Premature births
-
Inhibited growth of lung tissue in children
-
Premature death

Environmental Impact of Diesel Emissions:
Diesel engines and vehicles emit pollutants like particulate matter (PM), sulfur oxides (Sox), toxic
compounds, such as formaldehyde, and ozone precursors, such as NOx and VOCs. Ground level ozone
pollution causes crop and forestry losses. Particulate matter causes damage to materials and soils,
commonly used building materials and culturally important items such as statues and works of art. NOx,
Sox and particulate matter contribute to visibility impairment. NOx emissions contribute to the
acidification, nitrification and eutrophication of water bodies. To put it into simple terms, diesel
emissions help make everything dirty.

Take action to avoid exposure whenever and wherever possible.
Be pro active by keeping the air you breathe in the workplace clean and reasonably free from exhaust
fumes. Know and understand the risks and dangers these fumes present and what you can do to reduce or
eliminate them and encourage others to do the same. Protecting your lungs is no less important than
your eyes with safety glasses and your skin from chemicals with gloves.
-
You have the right to work in a safe, healthy environment. It's the law!
Check your local, state and federal regulations and guidelines for health and safety.
-
Work environments should have adequate ventilation. Operating vehicles indoors requires the use
of exhaust entrapment systems like exhaust hoses connected to vehicle tail pipes. The use of
vents
or open doors alone is not enough but should be used in conjunction with exhaust hoses and hoods.
-
Ask your employer for information on the hazards associated with diesel fumes, read it, make sure
you
understand it and if not, seek clarification.
-
Use all available ventilation devices and controls available to you, know how to use them and be able
to
detect any inoperative equipment.
-
Report any broken or ineffective equipment to your employer such as poor extraction fans, leaking
or
poor fitting hoses.
-
Understand and recognize the symptoms of over exposure: light-headedness or dizziness, vomiting,
coughing, sore throat, burning eyes. Know what to do: move the individual to fresh air and
seek medical attention is symptoms are severe.
-
Take actions to reduce emissions from the start. Turn off engines when not in use. Discourage
idling
and unnecessary operation of vehicles and machinery especially indoors.
-
Use emissions reducing systems like catalysts, particulate traps and low sulfur fuels and
lubricants.
Maintain vehicles and equipment and keep them running properly.
-
Checking for the presence of soot on the walls or on other surfaces in your workplace is a useful
indicator that diesel fumes are not being adequately controlled.
