Specific Safety Considerations
Dymax ECE series flood-lamp systems are designed to maximize operator safety and minimize exposure to
UV light-curing energy. To use the systems safely, they must be set up and operated in accordance with
the instructions in this user guide. Dymax assumes no liability for any changes that may impair the
protections of the ECE flood-lamp curing system. Please also read and understand the safety
considerations unique to UV light-curing systems as described below.
WARNING! Looking directly at the UV light emitted by an ECE flood lamp can result in eye
injury. To prevent eye injury, never look directly at the high-intensity light and always wear
protective goggles (provided).
Dymax UV Light-Curing System Safety Considerations
Operators must understand these four concepts to use the UV light source safely:
UV exposure
High-temperature surfaces
Ozone
Bright, visible light
Each is described below.
UV Exposure
Standard Dymax UV light-curing systems and bulbs have been designed primarily to emit UVA light (Figure
1). UVA light is generally considered the safest of the three UV ranges: UVA, UVB, and UVC. The American
Conference of Governmental Industrial Hygienists (ACGIH) does recommend Threshold Limit Values (TLVs)
for ultraviolet light.
The strictest interpretation of the TLV (over the UVA range) for workers’ eyes and skin allows continuous
exposure up to 1 mW/cm
2
(intensity). Unless you are placing bare hands into the curing area, it is unusual
to exceed these limits. To put 1 mW/cm
2
limit into perspective, a cloudless summer day will typically
