Black lights generate considerable heat during use. Extreme care must be exercised to prevent contacting
the housing with any part of the body.
To prevent injury to eyes, do not look directly into black light.
Prolonged direct exposure of hands to the filtered black light's main beam may be harmful. Suitable gloves
should be worn when exposing hands to the main beam.
Follow manufacturer's instructions when using black lights and filter.
Do not wear sunglasses or glasses with light-sensitive lenses during fluorescent penetrant inspections. They can
contribute to improper interpretation of defects.
Prolonged or repeated inhalation of vapors or powders may result in irritation of mucous membrane
areas of the nose.
Provide adequate ventilation when handling cleaner, emulsifier, penetrants, or developers.
Continual exposure to penetrant inspection material may cause skin irritation.
Observe the following when handling cleaners, emulsifiers, penetrants, or developers.
(1) Avoid contact with penetrant inspection materials by wearing neoprene gloves.
(2) Wash inside and outside of gloves.
(3) Wash exposed areas of body with soap and water.
(4) Check for traces of fluorescent penetrant materials on skin, clothing, and gloves using a black light source.
