Emergency Response Procedure
These immediate actions should be taken to protect personnel by establishing and maintaining a restricted area
around the radiation device allowing time to perform Emergency Response Actions in a controlled manner. Any
of the following conditions warrant implementation of the Emergency Response Procedures:
•
Inability to return the source to the fully shielded position within the device.
•
Damage to the device shielding creating elevated dose rates around the device.
•
A failure of any component that’s critical to the safe operation of the device.
During performance of emergency response actions, the Radiation Safety Officer or their alternate must maintain
control of the affected area.
1)
Actions to be Performed
i.
Stop and Think: Recognize an emergency situation exists. Follow company operating and emergency
procedures. Attempt to reduce external dose rates by remotely adding supplemental shielding (e.g.,
lead, concrete block, steel, etc.) around the elevated dose rate areas of the device.
ii.
Re-Establish the Restricted Area Boundaries: Survey the area and re-establish, or adjust as necessary,
the restricted area boundaries. Maintain control of radiation areas to ensure no unauthorized
personnel can gain access to the device or restricted area.
iii.
Notify QSA Global, Inc. and the Responsible Regulatory Authority: Advise of the situation, giving as
much detail as possible and obtain advice on further actions to take to return conditions to normal.
Information should include identification of the equipment involved, the cause of the incident, actions
taken to establish a safe condition, doses to all personnel involved and corrective actions taken to
prevent recurrence (if known at the time).
2)
Fires, spills and explosions:
Should the Model 989 exposure device be involved in a fire, perform the following actions:
i.
Survey the area surrounding the device and set up a restricted area (or controlled area) boundary if
necessary around the device location to limit radiation exposure to personnel.
ii.
Immediately contact your Radiation Safety Officer or Qualified Expert, QSA Global, Inc. and your
applicable regulatory agency to advise them of the situation, and determine what additional steps to
take in response to the handling and assessing the Model 989 exposure device and radiation source.
The radioactive source used in the Model 989 exposure device is a special form capsule that has been tested
up to 800°C. The radioactive material within the source capsule is solid, and will not leak from the container
similar to a liquid radioactive material spill. Performance of the semi-annual leak test confirms the integrity
of the sealed source containment.
