First Aid

Seek immediate medical attention for skin burns and direct UV exposure to

the eyes.

Microwave Radiation

WARNING: The lamp system utilizes high powered RF microwave energy

generated by a magnetron to provide power to the UV lamp. This

technology is identical to that of residential microwave ovens and like these

ovens can be dangerous if misused. The lamp system is safe provided that

the RF screen and gasketing are intact. Any damage such as rips or holes

in the screen may cause leakage of dangerous amounts of microwave

radiation. The power to the lamp is interlocked to the RF detector and will

shut down if microwave leakage exceeds safe levels. Any excessive

leakage will cause the system to shutdown.

Currently there are two organizations that set recommended guidelines for

exposure to occupational microwave radiation exposure, OSHA (U.S.

Department of labor, Occupational Safety and Health Administration −

Directive 29cfr 1910.97) and ANSI (American National Standards Institute −

Directive C95.1−1982). The ANSI directive, which is more stringent and

most commonly referred to, states that individuals should not be exposed to

microwave radiation levels above 8 mW/cm

at 2.45 GHz on a continuous

basis, or an average of 8 mW/cm

over a six minute period.

RF levels near the CoolWave 2 system installation should be checked

periodically. To measure RF levels, a hand-held survey meter is available

from ETS-Lindgren company. Their HI-1501 Survey Meter is calibrated for

2450 Mhz microwave sources and can measure RF levels from 0−2, 0−10,

and 0−100 mW/cm

Radio Interference

UV lamps are classified as non-consumer industrial, scientific, and medical

(ISM) equipment, as defined in Federal Communications Commission

(FCC) Rules and Regulations Volume 47, Part 18. As required by these

rules, Nordson Corporation verifies that their systems are capable of

compliance with applicable technical standards governing radiated

emissions when the equipment is properly maintained and is installed in an

appropriate light shield. This system complies with EN55011 (CISPR-1,

Group 2, Class A).

NOTE: Nordson UV lamps operate at a fundamental frequency of 2.45

GHz. They may cause interference with wireless local area networks

(WLANs) that also operate at this frequency.

Ozone

Ozone (O

) is a colorless gas that is generated by the reaction of

short-wave UV light (around 200−220 nanometers) with air, and it occurs

whenever high-energy electrical discharge is present.
