How to Procure X-ray Machines and Lasers
X-ray machines and lasers must be procured through the procurement process. They may not be purchased on a p-card. The procurement process will require the completion of an Addendum B for Hazardous Materials. EHS Radiation Safety will need to sign off on procurement of these devices. Thus, we urge all researchers to contact EHS Radiation Safety before they begin the process, to tell us what they are purchasing and where it will go. This way, EHS can quickly sign and return the addendum B and expedite the approval process.
X-ray and laser purchasers without a permit will need to apply for a new permit.
X-ray and laser purchasers with an existing permit will need to go through the amendment process.
How to Dispose of X-ray Machines
Any disposal or transfer of x-ray machines must be approved by EHS Radiation Safety. X-ray machines may be:
-Transferred to another UH researcher with an x-ray permit (with prior approval from Radiation Safety Officer)
-Returned to the manufacturer
-Sold to a licensed broker or registrant
-Disposed of as solid waste (consult with Radiation Safety)
When disposing of x-ray machines as solid waste, any hazardous material must be removed. The x-ray tube must be removed and disposed of properly. The lead shielding present in the machine, and any hazardous material used in cooling systems or other components must also be removed. In all cases, contact EHS before beginning disposal.
How to Dispose of Lasers
Any disposal of class 3B and 4 lasers must receive pre-approval from EHS Radiation Safety. Lasers may be:
-Transferred to another UH researcher with a laser permit (prior approval required)
-Returned to the manufacturer
-Sold to a licensed broker or registrant
-Disposed of as solid or electronic waste (consult with Radiation Safety)
In order to dispose of a laser as waste, any hazardous material must be removed. This includes the lasing media comprised of toxic chemicals or compressed gases. In addition, the laser must be permanently disabled or rendered inoperable, typically by severing the power cord. In all cases, contact EHS before beginning disposal.
