DAILY INSPECTION INSTRUCTIO NS 3.1 Introduction The QSA Global, Inc. Model 880 Delta, Sigma, Elit e and Omega radiographic exposu re devices provide innovation to the most widely used family of radi ographic exposu re devices utilized for on-site gamma radiography.
DAILY INSPECTION INSTRUCTIO NS 3.2 Figure 3.1 Source assembly and remote control cabl e con nectors 2 Exposure Device The source assembly is shown in the stored positio n in a titanium or ‘S’ tube at the center of the depleted Uranium shield of the exposur e device.
DAILY INSPECTION INSTRUCTIO NS 3.3 First, the locking mechanism requires a deliberate a c tion to enabl e exposure of the source assembly. This is accomplished by co upling the control cable co nnecto.
DAILY INSPECTION INSTRUCTIO NS 3.4 Transit Mode Rotating the handle of the remote control crank in the EXPOSE direction (count er-clockwi se) moves the source assembly out of the shielded position in t he exposu re device and into the source guide tubes (projection sheaths).
DAILY INSPECTION INSTRUCTIO NS 3.5 Figure 3.4 Sealed source in the exposure mode Daily Inspection of the System A daily inspection of the gamma radiography sy stem for obvious d efects is essential to ensure the equipment is in a safe and prop er o perating condition.
DAILY INSPECTION INSTRUCTIO NS 3.6 2 Inspect the labels on the exposu re device or the transport case to ensure they are legible and securely attached to the unit. The warning label cont aining the trefoil should be l egible fro m a distance of at least 3 ft (approximately 1 m).
DAILY INSPECTION INSTRUCTIO NS 3.7 odometers to obtain an approximation of the travel di st ance. One full revolution of the cra nk handle is equal to approximately 10 in (25.4 cm) of travel. Two remote control conduits (sheaths, housing s) are atta ched to the control crank.
DAILY INSPECTION INSTRUCTIO NS 3.8 2 Control Conduit Inspection : a. Inspect the control conduit where it is swag ed onto the fittings that mount on the control crank. There should be no evidence of cra cks or breaks in the PVC sheath. Also, look for bulges in that area that result from repeated flexing.
DAILY INSPECTION INSTRUCTIO NS 3.9 d. A final check of the control cable connector and sou rce assembly conne ctor i s accomplished by use of a Model 550 NO GO gauge to check for signi ficant we ar on the connectors that woul d affect safety. Without using excessive force, ch eck the followi ng four positions (se e figure 3.
