General Information

2.1.3 Class 1 LASER

2.1.4 Chemical and Biological Safety

A Class 1 LASER is installed in this instrument. Class 1 LASERS are products where the radiant power of the LASER beam accessible (the accessible emission) is always below the Maximum Permissible Exposure value. Therefore, for Class 1 LASERS the output power is below the level at which it is believed eye damage will occur. Exposure to the beam of a Class 1 LASER will not result in eye injury. Class 1 LASERS may therefore be considered safe. However, Class 1 LASER products may contain LASER systems of a higher Class but there are adequate engineering control measures to ensure that access to the beam is not reasonably likely. Examples of such products include LASER printers and compact disc players. CDRH assession number 0510555-02.
Data: 0.3 mW; wavelength = 650 nm
DANGER Potential Chemical/ Biological Exposure Hazards. Handling chemical samples, standards and reagents can be dangerous. Users of this product are advised to familiarize themselves with safety procedures and the correct use of chemicals, and to carefully read all relevant Material Safety Data Sheets.

2.1.5 Source Lamp Safety

Normal operation of this instrument may involve the use of hazardous chemicals or biologically harmful samples.
The user must observe all cautionary information printed on the original solution containers and safety data sheet prior to their use.
All waste solutions must be disposed in accordance with local and national law.
The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
The source lamp operate at high temperatures.
To avoid a possible electric shock, disconnect the instrument from the power source before servicing the lamp. Make sure that the instrument cannot be accidentally switched on again.
CAUTION The UV lamp generates UV light. Do not look directly at an operating lamp without wearing UV protective eye glasses.
