Firefighters face exposure risks long before they arrive on scene. Diesel exhaust in and around the station is one of the hazards departments can address with the right exhaust removal strategy.
Apparatus start-ups, low idle operation, backing into the bay, and routine station movement can all create exhaust exposure opportunities for firefighters, EMS crews, mechanics, and station personnel.
Cancer prevention is not one single action. It is a complete operating approach: remove exhaust at the source, control contaminated gear, decontaminate after calls, follow best practices, and keep education in front of every crew member.
Diesel exhaust exposure is a serious concern for fire stations and emergency fleets. A strong prevention plan should reduce unnecessary exposure wherever possible, including inside the station and around emergency vehicles.
Traditional hose systems and NO SMOKE filtration systems are both designed to address exhaust exposure, but they work very differently. The best choice depends on how your department operates, your station layout, and where protection is needed.
NO SMOKE is mounted directly to the apparatus, filtering exhaust at the vehicle without requiring an overhead hose connection before response.
Hose systems are typically mounted inside the station and connect to the exhaust pipe or stack to capture exhaust while the apparatus is in the bay.
| Consideration | NO SMOKE Filter Systems | Hose Systems |
|---|---|---|
| System Location | Mounted directly on the vehicle | Mounted in the station or apparatus bay |
| Connection Before Response | No overhead hose connection required | Often requires a hose connection or track system |
| On-Scene Protection | Can support filtration around the apparatus while operating | Generally limited to the station environment |
| Station Layout Impact | Less dependent on bay layout, track location, or ceiling design | May require bay modifications, tracks, rails, or hose drops |
| Special Apparatus | Can be reviewed around the specific vehicle and exhaust configuration | May be challenging with tall vehicles, vertical stacks, or tight bays |
| Best Fit | Departments that want vehicle-mounted exhaust protection beyond the bay | Departments focused only on exhaust capture inside a controlled bay layout |
A vehicle-mounted system helps address a common limitation of station-only exhaust removal: once the apparatus leaves the bay, the station system stays behind.
NO SMOKE is designed around the vehicle, helping reduce exhaust exposure during cold starts, low idle, station operation, response movement, and on-scene use.
