Personal Safety
To prevent injury follow these instructions.
S Do not operate or service equipment unless you are qualified.
S Do not operate equipment unless safety guards, light shields, doors,
and/or covers are intact and automatic interlocks are operating properly.
Do not bypass or disarm any safety devices.
S Keep clear of moving equipment. Before adjusting or servicing any
moving equipment, shut off the system controller and wait until the
equipment comes to a complete stop. Lock out power and secure the
equipment to prevent unexpected movement.
S Obtain and read Material Safety Data Sheets (MSDS) for all materials
used. Follow the manufacturer’s instructions for safe handling and use
of materials. Always use recommended personal protection devices.
S Make sure the UV area is adequately ventilated.
S The UV equipment runs at extremely high temperatures. Do not touch
the UV lamphead face during operation or immediately after shutting off
the equipment.
S To prevent injury, be aware of less-obvious dangers in the workplace
that often cannot be completely eliminated, such as hot surfaces, sharp
edges, energized electrical circuits, and moving parts that cannot be
enclosed or otherwise guarded for practical reasons.
S Always wear safety glasses that offer UV protection.
S Never expose any part of the body to direct or indirect UV light.
Ultraviolet Radiation
WARNING: Ultraviolet light is a form of electromagnetic radiation and can
be harmful if exposure exceeds recommended levels. Protect eyes and skin
from direct exposure to UV light. All equipment or areas where UV light is
used must be adequately guarded, shielded, and interlocked to prevent
accidental exposure.
Ultraviolet light is not capable of penetrating into the body and interacting
with internal tissues and organs.
The National Institute for Occupational Safety and Health (NIOSH)
document Criteria for Recommended Standard... Occupational Exposure to
Ultraviolet Radiation (PB214 268) establishes guidelines for safe use.
See Figure 1-2. Ultraviolet light is divided into wavelength bands A, B, C,
and V along with vacuum UV. Although values for wavelength bands will
vary depending on the source, the following ranges may be used as a
guide.
S UV-V (450−400 nanometers) – visible UV.
S UV-A (400−315 nanometers) − represents the largest portion of UV
energy and is most responsible for human skin aging and increased
pigmentation. UV−A is at the lower limit of sensitivity to the human eye.
S UV-B (315−280 nanometers) − most responsible for reddening and
burning of the skin and damage to the eyes.
S UV-C (280−100 nanometers)
