Ozone
Issues:
• The emitters used with the UVB-100 produce ozone when they’re operated in air (that is, outside vacuum
conditions). Ozone vapors are harmful (they can cause mucous membrane damage) so should not be
breathed. When there’s a high enough concentration of ozone, it is a poisonous gas.
•
Additionally, there is a risk of explosion if the system is pumped out with a hydrocarbon oil mechanical
pump when large amounts of ozone are present.
Prevention & Protection:
How do we help protect you?
•
The UVB-100 controller key: The UVB-100 controller includes a key that must be used for the UVB-100
emitters to operate. See “What must you do...”, below, for more information.
What must you do to help protect yourselves?
•
Use the UVB-100 emitters only in vacuum situations. Do not operate the UVB-100 emitters in air.
•
For those applications that require pumping at pressures approaching atmosphere or applications that desire
the production of ozone, an inert mechanical pump fluid such as Fomblin or Krytox should be used because
they are not reactive with oxygen.
•
Manage the use of the UVB-100 controller key. Identify the personnel in your organization who are
qualified to use the key and ensure that only these personnel have access to the key.
•
Ensure that the key for the UVB-100 controller is kept in a secure location.
