Unless otherwise specified, the reference to WARD DIESEL NO SMOKE in this FAQ section includes WARD DIESEL NO SMOKE and WARD DIESEL NO SMOKE 2. If this FAQ section does not answer your questions, click here to contact us.

Are FEMA Grant funds available?
Yes. WARD DIESEL NO SMOKE is highly funded and approved by the Assistance to Firefighters Grant Program (AFG Grant). Ask us for the Grant Assistance Package with copies of successful applications for WARD DIESEL NO SMOKE or click here for AFG Grant page.

Does WARD DIESEL NO SMOKE void the engine warranty?
NO. Letters have been provided by engine manufacturers.

How is WARD DIESEL NO SMOKE automatic?
The WARD DIESEL NO SMOKE system automatically activates upon startup and when the transmission is put into reverse upon re-entry to the station. This critical automatic feature is a more "fool proof" means to ensure that the system is utilized.

The term direct source capture is mentioned in the various standards. What is direct source capture?
A direct source capture system is a vehicle exhaust removal system that is connected to the exhaust train on the vehicle. In other words, by definition, it is physically part of the exhaust system.

We move our vehicles from bay to bay in the firehouse. Are we locked into a bay with WARD DIESEL NO SMOKE?
WARD DIESEL NO SMOKE is an on-board system. WARD DIESEL NO SMOKE provides freedom of movement. There are no hose drops which lock the vehicle into a bay. Also, there are no hanging hoses swinging in the fire station and creating a safety hazard.

What about our health and safety concern of inhaling and ingesting diesel exhaust to hook up the hose?
This is one of the biggest advantages of the apparatus-mounted system - it direct source captures the toxic diesel exhaust at the tailpipe. Therefore, it does not require diesel exhaust inhalation by personnel while hooking up a hose as the rig is backed into the station. This is commonly referred to as the so-called "bend-over for the back-in" problem.

What are the health hazards of diesel exhaust inhalation (in a confined structure - i.e., firehouse)?
Health effects of diesel exhaust of both long and short term exposure include:

  • Premature Death
  • Lung Cancer
  • Heart Attacks
  • Testicular Cancer
  • Chronic Bronchitis
  • Neurological Damage
  • Liver/Kidney Damage
  • Aggravated Asthma
  • Exacerbated Allergies
  • Lower Resistance - Respiratory Infections

    Consider these findings:

  • American Heart Association: "Diesel Exhaust Associated with Higher Heart Attack, Stroke Risk in Men"

  • Reuters: "Diesel Fumes Can Affect Your Brain, Scientists Say"

  • New York Times: "Soot Particles Strongly Tied to Lung Cancer"

  • EPA Report: "...long-term (i.e., chronic) inhalation exposure is likely to pose a lung cancer hazard to humans..."

    What are the OSHA standards?
    OSHA measures Permissible Exposure Limits (PELs) over a time weighted average 8 hour day. PELs - Carbon Monoxide 35 PPM, Sulfur Dioxide 5 PPM, PNAs 1 PPM, Diesel Particulate Matter 1 PPM, Nitrogen Oxide 25 PPM, Nitrogen Dioxide 5 PPM. WARD DIESEL NO SMOKE meets and exceeds OSHA, NIOSH, NFPA, and is FEMA (AFG) Grant approved.

    What does NFPA state?
    NFPA 1500 9.1.6: "The fire department shall prevent exposure to firefighters and contamination of living and sleeping areas to exhaust emissions."

    What if we do not have source capture? (We have ceiling-mounted air exchangers that kick up dust)?
    Current standards call for 100% effective source capture systems. The best available control technology captures the exhaust contamination at the source.

    What is diesel exhaust?
    Diesel exhaust is a complex mixture of toxic compounds including the termed "carcinogen" Diesel Particulate Matter (DPM), commonly termed "soot". Diesel exhaust also contains certain Nitrogen Oxides (NOx), Polyaromatic Hydrocarbons (PNAs), Sulfur Dioxide (SO2), and Carbon Monoxide (CO). Some DPM (soot) particles are large or dark enough to be seen as soot or smoke. Others are so small that several thousand of them could fit on the period at the end of this sentence. The smallest diesel particles are diameters below 50 nanometers (a nanometer is one million times smaller than the head of a pin). Newer diesel engines emit higher numbers of small particles than the older vehicles. Research has shown that the smallest diesel particles are of the greatest health concern as they will penetrate deep into sensitive areas of the respiratory tract.

    What is the frequency of filter changes on the WARD DIESEL NO SMOKE?
    There are a number of variables that affect the frequency of filter changes including timer setting, the age of the engine, the sulfur content of fuel, and the number of runs. For instance, large city fire department WARD DIESEL NO SMOKE users such as Indianapolis F.D., Nashville F.D., Sacramento F.D., or San Antonio F.D. typically change their WARD DIESEL NO SMOKE filters approximately once a year. On the other hand, a volunteer fire department might go 10 years between filter changes. In general, most fire departments go 2-3 years between filter changes. Note that these guidelines on filter changes do not apply to the WARD DIESEL NO SMOKE 2.

    What is the WARD DIESEL NO SMOKE over-ride switch? What about soot/fumes on-scene?
    WARD DIESEL NO SMOKE now provides clean emissions on-scene. With the flip of a switch, the WARD DIESEL NO SMOKE over-ride feature activates the filter system. For ambulances in front of hospital doors, the system can be activated to keep the hazardous, nuisance soot from being breathed by hospital and emergency personnel, and patients. No more shutting off the vehicle in front of hospital doors, which is not a viable option in extreme weather conditions.

    WARD DIESEL NO SMOKE 2 is an exciting new product improvement and enhancement by Ward Diesel Filter Systems. The new high performance substrate with proprietary wash coat removes gaseous matter on 2007 model engines. 2007 model engines address emissions for the environment. WARD DIESEL NO SMOKE 2 provides the clean air you need in the firehouse, within the enclosed structure, for an important health and safety upgrade.

    Why the decision for the apparatus-mounted exhaust removal system (i.e. WARD DIESEL NO SMOKE)?
    WARD DIESEL NO SMOKE is fully automatic, involving no manual hose hook-ups.
