Other precautions 
Both the deuterium and the visible lamps operate at high 
temperatures, and touching either of these lamps may result in 
burns. Before replacing a lamp that has been lit, switch off the 
spectrophotometer and either ensure that the lamp has cooled, or 
protect your fingers from burns.  
Do not block the ventilation grilles on the spectrophotometer and 
accessories. Consult the manuals supplied with your computer, 
monitor and printer for their specific ventilation requirements. 
Use of the Cary system and accessories may involve materials, 
solvents and solutions which are flammable, corrosive, toxic or 
otherwise hazardous. 
Careless, improper, or unskilled use of such materials, solvents and 
solutions can create explosion hazards, fire hazards, toxicity and 
other hazards which can result in death, serious personal injury, and 
damage to equipment and property. 
ALWAYS ensure that laboratory safety practices governing the use, 
handling and disposal of such materials are strictly observed. These 
safety practices should include the wearing of appropriate safety 
clothing and safety glasses.
