Garage exhaust removal systems capture emissions directly at the source to move contaminated air away from breathing zones. Capturing vehicle exhaust at the source minimizes air movement, reduces energy usage, and keeps the air clean and breathable. Continue reading to learn about various pollutants in connection with garage exhaust emissions and how to reduce the risk of overexposure in garages, workshops, and more.
Carbon Monoxide (CO): The Silent Killer in Your Garage
Carbon monoxide is a colorless, odorless gas produced when fuel combustion is incomplete — a common byproduct of vehicle exhaust. Even in small amounts, CO can bind to hemoglobin in your blood, reducing oxygen flow to vital organs like the brain and heart. Exposure can lead to serious health risks, including death in high concentrations.
Symptoms of exposure include:
• Shortness of breath
• Dizziness or lightheadedness
• Confusion or disorientation
• Nausea and headaches
How to protect yourself:
• Always use a properly installed garage exhaust removal system.
• Ensure your garage is well-ventilated to prevent carbon monoxide buildup.
• Install a carbon monoxide detector in your workspace.
Nitrogen Dioxide (NO₂): A Hidden Respiratory Hazard
Nitrogen dioxide and other nitrogen oxides (NOₓ) are produced when fuel is burned at high temperatures, especially in vehicle engines. These gases contribute to smog formation and can cause serious respiratory issues when inhaled.
Symptoms of exposure include:
• Coughing and wheezing
• Shortness of breath
• Chest pain or tightness
• Increased risk of asthma attacks
How to protect yourself:
• Use an exhaust removal system that captures emissions directly at the tailpipe.
• Maintain vehicle engines to reduce NO₂ emissions.
• Keep your workspace ventilated and perform regular air quality checks.
Benzene & Formaldehyde: Dangerous Carcinogens in Garage Exhaust
Benzene and formaldehyde are toxic air pollutants found in vehicle exhaust fumes. Both are known or suspected carcinogens, with long-term exposure linked to cancer, birth defects, and genetic mutations.
Symptoms of exposure include:
• Dizziness or headaches
• Irritation of the eyes, nose, and throat
• Long-term risk of cancer and organ damage
How to protect yourself:
• Use high-quality exhaust hoses and removal systems to capture and vent fumes.
• Minimize engine idling inside enclosed spaces.
• Wear appropriate respiratory protection when exposure risk is high.
Sulfur Dioxide (SO₂): The Airway Irritant
Sulfur dioxide is released when diesel fuel containing sulfur is burned. It’s a pungent, colorless gas that can quickly irritate airways and trigger respiratory issues.
Symptoms of exposure include:
• Throat irritation
• Shortness of breath
• Aggravated asthma symptoms
How to protect yourself:
• Use low-sulfur fuel when possible.
• Install and maintain a garage exhaust removal system.
• Limit engine run time inside enclosed garages.
Ozone (O₃): The Smog Component You Don’t See
Ozone is not emitted directly from vehicles but forms when hydrocarbons and nitrogen oxides react in sunlight. It’s a key component of smog and can have serious effects on lung function.
Symptoms of exposure include:
• Coughing and throat irritation
• Chest pain
• Shortness of breath
• Reduced lung capacity
How to protect yourself:
• Capture and remove vehicle emissions at the source.
• Keep doors and windows open when working indoors, especially during summer months.
• Monitor outdoor air quality when garage doors are open.
Particulate Matter (PM): Tiny Particles, Big Risks
Particulate matter is made up of microscopic particles from fuel combustion that can penetrate deep into the lungs. These fine particles can cause irritation and long-term health problems.
Symptoms of exposure include:
• Wheezing and coughing
• Shortness of breath
• Aggravated asthma symptoms
How to protect yourself:
• Use exhaust removal systems designed to minimize particulate emissions.
• Keep your work area clean and dust-free to avoid additional air quality issues.
• Schedule regular equipment maintenance to reduce particulate output.

WARNING: Vehicle Exhaust is extremely dangerous and potentially deadly. We always recommend that any system be properly engineered to meet the specifications of your application. If you are using our Crushproof system, we recommend that you use it with a fan and as an intermittent repair solution only, not to be run for long periods of time. This hose is to be used only with naturally aspirated 4 cycle engines running at an idle and under no load. We recommend keeping any run of hose as short as possible preferably 11' or under and sized to include ambient air to cool the exhaust temperatures. This hose is designed to handle frequent temperatures up to 400° and intermittent temperatures to 600°. When using Crushproof hose for the first time, watch closely to verify that the exhaust is exiting the building as designed. IF YOU SEE ANY EXHAUST COMING BACK INTO THE SPACE, THE HOSE IS NOT BEING USED PROPERLY. TURN THE VEHICLE OFF IMMEDIATELY AND CALL OUR EXPERTS.
