PERCENT ACETIC ACID. IF ELECTROLYTE GETS INTO THE EYES, FLUSH
WITH WATER AND GET IMMEDIATE MEDICAL ATTENTION.
3. Because of the potential hazards mentioned above, the serviceman must remove rings, wrist watch,
etc. and WEAR SAFETY GOGGLES when working on or near the battery. He must follow battery
| installation and maintenance procedures given in Chapters 3 and 8. Furthermore, the serviceman
should not leave the x-ray unit unattended with the battery compartment cover and the ::assette
tray removed, unless adequate warning signs and safety measures to limit access to the area are made.
4. The x-ray control access door, shown in Illustration 3-1, can be opened only with a key. Because of
the possible electrical shock and other hazards present when this door is opened, the key should not
be left in the lock but should be retained by the serviceman or by the customer. The serviceman
should not leave this unit unattended with the door unlocked and open, unless adequate warning
sions and safety measures to limit access to the area are made.
5. When recharging the battery, the x-ray unit must be located in a large ventilated room. During
normal charging conditions and when all batteries are functioning properly, there is little or no gas
emitted. Should abnormal conditions develop, there could be an accumulation of hydrogen gas
which, if confined in a small space, would be explosive in the presence of flame or electrical spark.
Whenever the extension cord plug is inserted in a wall outlet, a fan ventilates the battery compartment.
A hazardous situation will not develop where the outflow from this compartment is into a large or
a well ventilated small room.
6. An audible tone and/or red x-ray light indicated presence of radiation. If either indicator is on at
any time other than the expected x-ray exposure interval, immediately release the handswith X-RAY
and ROTOR buttons and move the Main Power Circuit Breaker to OFF. Perform the procedure for
disconnecting the HV Transformer before attempting to determine the malfunction.
THIS UNIT IS NOT DESIGNED FOR USE IN HAZARDOUS AREAS.
