Safety Practices and Hazards 
6  Cary 100/300/4000/5000/6000i/7000 Spectrophotometers User’s Guide 
Verifying Safe State 
The following general safety precautions must be observed during all 
phases of operation, maintenance and service of this instrument.  
To ensure continued safety of the instrument after maintenance or 
service procedures verify the instrument is returned to a safe state 
for the user. This includes running performance checks to verify the 
instruments safety systems are functioning correctly. Check the 
general condition of the instrument during operation for wear or 
signs of corrosion that are likely to inhibit function or safety. 
Failure to comply with these precautions or with specific warnings 
elsewhere in this manual violates safety standards of design, 
manufacture, and intended use of the instrument. Agilent 
Technologies assumes no liability for the customer’s failure to 
comply with these requirements. 
Ultraviolet radiation 
The deuterium (standard in all instruments) and mercury lamps (if 
fitted) in the instrument emit hazardous ultraviolet (UV) radiation. 
This radiation can cause serious damage to eyes. NEVER look 
directly at either lamp and NEVER operate either lamp unless it is 
correctly mounted in the lamp turret (Cary 4000/5000/6000i/7000 
only) and the turret is correctly mounted in the instrument. 
NOTE 
The mercury lamp is fitted as standard in the Cary 4000/5000/6000i/7000. 
Electrical hazards 
The Cary 100/300/4000/5000/6000i/7000 instruments and some 
accessories contain electrical circuits, devices, and components 
operating at dangerous voltages. Contact with these circuits, devices 
and components can cause death, serious injury, or painful electrical 
shock.
