Safety Concerns With Uv - GAYLORD Ultima Vent GX2-UV Technical Manual

As with many types of technology if it is not used properly and/
or proper precautions are not taken there is the potential for
injury or harm. This is especially true with UVC light due to
the fact that it does not physically hurt at the time of exposure.
While UVC is very effective at breaking down grease mol-
ecules, direct exposure to large amounts is harmful to skin
and eyes. The amount of UVC generated in these hoods is
greater than that what results from direct exposure to the sun.
Under no circumstances is it acceptable to view the lighted
lamps without proper eye protection or expose bare skin
directly to the light. All interlocks and safety precautions
called for in this manual must be followed to avoid the potential
for harm to service personnel and/or operators. In addition,
only trained and authorized personnel may perform some
maintenance See previous page for details.
Personal Protective Equipment
1. Eye protection that prevents 100% of UVC being trans-
mitted through the lens must be worn at all times when
performing service work on any Ultima Vent that is
energized and/or has the potential to be energized and
expose personnel to UVC light.
2. Whenever service work is performed it is recommended
that long sleeve pants and shirts be worn to minimize the
potential for inadvertent exposure of the skin to UVC.
Safety Interlocks
