SAFETY AND MAINTENANCE PROCEDURES

PROPER USE OF X-RAY TUBES ARE THE RESPONSIBILITY OF EQUIPMENT MANUFACTURERS AND USERS.
CARE MUST BE EXERCISED WHEN INCORPORATING TUBES INTO AN X-RAY SYSTEM TO ENSURE THAT
THE SYSTEM EARTH LEAKAGE CURRENT COMPLIES WITH APPROPRIATE END-PRODUCT SAFETY
STANDARDS AND RELEVANT LOCAL INSTALLATION REQUIREMENTS.
RESPONSIBILITY FOR AFTER-SALE OPERATING AND SAFETY PRACTICES. LIMITED LIFE AND RANDOM
FAILURES ARE INHERENT CHARACTERISTICS OF X-RAY TUBES.
X-RAY TUBES CONTAIN MATERIAL THAT MAY BE HARMFUL TO THE ENVIRONMENT AND HUMANS.
DISPOSE OF X-RAY TUBES IN ACCORDANCE WITH APPLICABLE REGULATIONS. IT IS RECOMMENDED THAT
FAILED TUBES BE RETURNED TO THE MANUFACTURER OR AN APPROPRIATE FACILITY TO ENSURE
PROPER HANDLING.
ALL PERSONS WHO WORK WITH X-RAY TUBES MUST PROTECT THEMSELVES AGAINST RADIATION
EXPOSURE AND POSSIBLE SERIOUS BODILY INJURY.
A. Safety
1. Do not operate this tube except in accordance with the Technical Data Sheet, these precautions and any additional
information provided by equipment manufacturers.
2. Ensure that the Thermal or Pressure switch is properly connected, operating, and is not bypassed.
3. Preferred method of cleaning tube housing assemblies is with alcohol, methanol or hospital grade disinfectant.
X-ray tube assembly is not intended to come into contact with patients.
4. X-Ray tube assemblies are classified as ordinary equipment and not protected against ingress of water.
5. This product is not to be used in the presence of a flammable anesthetic mixture with air or with oxygen or with

PRODUCTS
SERIOUS HAZARDS EXIST IN THE OPERATION OF X-RAY TUBES.
HIGH VOLTAGE SHOCK – As much as 150,000 volts, and can be lethal. When direct access to receptacles
is required, primary circuits must be disabled and capacitors/cables discharged.
RADIATION EXPOSURE – When energized, radiation in the x-ray spectra are damaging to human tissue.
BERYLLIUM (Be) POISONING – Dust or fumes from Be in metal center sections are highly toxic and can
cause serious injury or death. Do not perform operations which produce dust or fumes, such as grinding, grit
blasting or acid cleaning.
GLASS EXPLOSION – Breaking glass envelopes can cause implosion, resulting in scattering of glass
particles. Handle glass tubes carefully.
BURNS – Housings containing dielectric oil may reach scalding temperatures. Over heating and resultant
rupture can cause serious burns.
