An aircraft maintenance technician (amt) describes his work environment where deteriorated fuel tank ventilation hoses were not only a trip hazard on the hangar floor but the hose seals were venting fumes from the fuel tanks of a cessna ce-560XL aircraft into the work area. Technician experienced nausea and headaches.

Narrative:
A cessna ce-560XL aircraft was in for a-check inspection and fuel tanks were drained and opened for non-destructive testing (ndt) inspection. Fuel tank ventilation system installed to vent tanks to outside. However; the hoses used; stretched from bay #3 to west garage door. Hoses become trip hazard and also do not seal properly; venting fumes into work area. Hoses appear to need maintenance due to deterioration. Attempted to use the sirius multi gas detector to see what level jet a fumes were at; but was unable to calibrate unit due to calibration gasses being empty. I have been in this area of the hangar since xa:30pm and I am experiencing nausea and headaches. I recommend to install overhead vent system so that vent lines are not on floor and fumes vent out; or install an inline blower into the system now in use to provide positive airflow to push the fumes out of the hangar. Venting open fuel tanks for ndt. Excess fumes from fuel tank venting system.
