Prevention & Protection

Because avoiding an accident is the best way to protect your crew and community, the PROTECH System by E-ONE features the unique OnGuard® collision warning and mitigation system, G4® (electronic stability control), the CrewGuard occupant detection system, a 360-degree camera system and backup sensors. Combined with protection, or as we like to call it, ProTech-tion, E-ONE provides the safest technology package for your crew.


We test and re-test E-ONE fire trucks until they exceed SAE, ECE and NFPA standards. In fact, our cab structure withstood over five times the static roof load and over twice the frontal impact required by the NFPA and SAE, making it the strongest cab in the industry. Every E-ONE cab is designed with a structural roll cage to provide maximum protection and the highest levels of performance — structural extrusions and sub-frames, full flange wishbone frame rail, center uprights and crossbeam extrusions. Your next E-ONE Fire Truck comes with horizontal and vertical supports to carry vertical loads, thicker, 3/16” aluminum-alloy exterior skin material and more. On-site testing capabilities include tilt and stability, pump testing, cab water-leak testing, aerial stability testing on both flat ground and a five degree slope, weight scales, waterway flow testing, bumper turret under truck nozzle spray testing, load bank testing, and grade ability testing.
